Summary Title: Carbon Neutral Natural Gas Portfolio Plan
Title: Utilities Advisory Commission Recommendation that Council Adopt a
Resolution Approving a Carbon Neutral Natural Gas Portfolio Plan to Achieve
Maximum Carbon Neutrality Using a Combination of Offsets and Biogas in
the Gas Supply Portfolio by Fiscal Year 2018 with No Greater than 10¢/Therm
Rate Impact; and Related Termination of the Palo Alto Green Gas Program
From: City Manager
Lead Department: Utilities
Recommendation
Staff and the Utilities Advisory Commission (UAC) recommend that the Finance Committee
recommend Council:
1. Adopt a resolution (Attachment A) that:
a. Approves the Carbon Neutral Gas Plan, enabling the City to achieve a carbon-neutral
gas supply portfolio starting in fiscal year (FY) 2018 with a rate impact not to exceed
ten cents per therm (10 ₵/therm); and
b. Terminates the PaloAltoGreen Gas program established by Resolution 9405; and
2. Direct staff to develop an implementation plan for the Carbon Neutral Gas Plan.
Executive Summary
The proposed Carbon Neutral Gas Plan will achieve carbon neutrality for the gas supply
portfolio by FY 2018 with a combination of high-quality environmental offsets and physical
“biogas” or “biomethane”. The proposed cost cap to implement the plan is 10 ₵/therm. Based
on current rates, this equates to about a 10% gas rate increase. For the median residential
customer usage, the additional cost of a 10 ₵/therm gas rate increase is about $43 per year.
The PaloAltoGreen Gas (PAG Gas) program was launched in December 2014. PAG Gas is a
voluntary program providing customers with the option to negate the impact of greenhouse
gas (GHG) emissions associated with their natural gas usage by purchasing environmental
offsets. Implementation of a carbon-neutral gas portfolio renders the voluntary program
redundant, therefore, termination of PAG Gas is recommended when implementing the Carbon
Neutral Gas Plan.

The UAC reviewed the proposed Carbon Neutral Gas Plan on August 31, 2016 and voted to
recommend that Council approve the proposed plan.
Background
City’s GHG Emissions from Natural Gas
Table 1 below, based on data from the 2016 Earth Day report (Staff Report 6754), shows the
estimate for City and community GHG emissions for 1990, 2005, 2012, and 2015.
Table 1
Palo Alto Community and City Greenhouse Gas Emissions (in 000’s of Metric Tons of CO2e)
Emissions Category 1990 2005 2012 2015
Natural Gas Use 194 166 160 135
Electricity Use 186 160 75 0

Total 780 752 591 501
* Consultant estimate based on population, employment, vehicle miles travelled and
vehicular emission profiles
** Includes landfill, refuse and Regional Water Quality Control Plant emissions
As shown in Table 1, GHG emissions from natural gas use in 2015 were reduced by 4,406 tons
due to the PAG Gas program. The bulk of the reduction in emissions associated with natural gas
use is associated with reduced natural gas use (from 37.2 million therms in 1990 to 30.1 million
therms in 2012 to 25.5 million therms in 2015).
Gas Utility Long-term Plan (GULP) and Early Evaluations of Alternative Gas Supplies
In November 2009, the UAC reviewed an analysis of physical biogas as a resource for the gas
supply portfolio.1 At that time, staff determined that physical biogas cost about 50 ₵/therm
more than natural gas, or about $100 per ton of carbon dioxide equivalent (CO2e)2 and would
increase a residential customer’s gas bill by 35%.
GULP includes a strategy to evaluate a voluntary green gas program and evaluate purchasing
non-fossil fuel gas for the gas portfolio. The City Council last approved updates to GULP in April
2012 (Staff Report 2522, Resolution 9244), including GULP Strategy 4:
Reduce the carbon intensity of the gas portfolio in accordance with the Climate
Protection Plan by:
a. Designing and implementing a voluntary retail program using reasonably
priced non‐fossil fuel gas resources; and
b. Purchasing non‐fossil fuel gas for the portfolio as long as it can be done with
no rate impact.

City of Palo Alto Page 3
In response to the GULP strategies, in April 2013, staff presented alternatives for a PAG Gas
program to the UAC3 including the use of physical biogas for the program, but found that it
would cost about $1 per therm more than natural gas based on responses to a request for
proposal issued by the Northern California Power Agency. In addition, the long-term contracts
required for biogas project developers to secure financing were, and are still, not conducive to
the potentially volatile demand associated with a voluntary green gas program.
PAG Gas
The PAG Gas program was modeled after the highly successful, voluntary PaloAltoGreen (PAG)
program, which allowed participants to receive 100% renewable energy and eliminate the GHG
emissions associated with their electricity use. Participation rates in PAG were the highest
among similar programs throughout the nation earning recognition for the City and creating a
sense of community pride around sustainability efforts. In 2012, approximately 20% of CPAU’s
customers participated in PAG, representing 8% of the City’s total electric usage.
By 2013, the City’s aggressive Renewable Portfolio Standard (RPS) goal combined with its
carbon-free hydroelectric resources rendered the electric supply portfolio largely carbon
neutral. In March 2013, City Council approved the Carbon Neutral Plan committing CPAU to
pursue only carbon neutral electric resources beginning in calendar year 2013 (Staff Report
3550, Resolution 9322). In September 2013, City Council suspended PAG and directed staff to
develop a new voluntary PAG Gas program to afford participants the opportunity to eliminate
the GHG emissions associated with their natural gas use (Staff Report 4041, Resolution 9372).4
In April 2014, City Council approved the establishment of a voluntary PAG Gas program (Staff
Report 4596, Resolution 9405) using high quality offsets to back the program. All offsets
purchased to date have been from a livestock methane capture project. The PAG Gas rate is
12₵/therm, which equates to an avoided GHG emissions cost of approximately $22 per ton of
CO2e.
The PAG Gas program goal is a 20% participation rate by 2020 with a corresponding GHG
reduction of 16,000 tons of CO2e per year. The 2020 goal represents a 10% reduction in the
City’s total GHG emissions associated with natural gas consumption. The reductions are
achieved by purchasing high quality environmental offsets, with a preference for California
projects, on behalf of participants in order to reduce or eliminate the impact of GHG emissions
associated with each participating customer’s gas usage. All customers can sign up for PAG Gas
3 https://www.cityofpaloalto.org/civicax/filebank/documents/33744
4 In June 2014, since the PAG (electric) program is redundant with the Carbon Neutral Plan, Council eliminated the
PAG program for residential customers (Staff Report 4718, Resolution 9422). At the same time, Council also
reactivated the program for commercial customers since some customers (including City facilities) desire to
participate in a voluntary green electric program to achieve environmental recognition and certifications in line
with their own corporate sustainability goals including participation in the U.S. Green Building Council Leadership
in Energy and Environmental Design (USGBC LEED) Program and the U.S. EPA Green Power Partnership Program.
City of Palo Alto Page 4
for their entire gas usage; commercial customers also have the option of participating in the
program for part of their natural gas usage.
Since the program launch in December 2014, roughly 4% of the City’s residential natural gas
customers have participated in PAG Gas accounting for approximately 3,200 tons of GHG
emissions per year. City facilities began participating in PAG Gas in July 2015 and account for
GHG emissions reductions of approximately 6,000 tons per year. For a typical residential
customer participating in PAG Gas, the cost is approximately $5 per month for an average use
of 42 therms per month. After the June 1, 2016 UAC meeting, staff began to evaluate carbon
neutral gas supply options and suspended active marketing of the program, resulting in
decreased participation in the program.
Figure 1 below shows the trajectory of PAG Gas participation for January 2015 through July
2016.
Figure 1: PAG Gas Program Participation
Figure 2 below shows the number of PAG Gas participants by customer type. Figure 3 shows the
percentage of total gas usage by customer type. As shown, the vast majority of participants are
residential customers—as was the case with the PAG (electric) program. The bulk of the
City of Palo Alto Page 5
participation in terms of gas usage is for City facilities. Very few commercial customers have
participated in the program to date.
Approximately 4.1% of the City’s residential natural gas customers have signed up for PAG Gas
as of the end of June 2016. In July 2015 all City facilities began participating in the program for
100% of their gas usage.

Utilities Advisory Commission Discussions
At its October 7, 2015 meeting the UAC heard public comment on, and discussed the merits
and drawbacks of, an opt-in versus an opt-out structure for the voluntary PAG Gas program.
The minutes from that meeting are provided as Attachment B. At its June 1, 2016, meeting the
UAC was presented with an overview and high-level analysis of several options for reducing the
carbon impact of natural gas use in the City including converting the voluntary program to an
opt-out model (meaning all customers would be automatically enrolled in the program, but
could voluntarily leave the program at any time) and adopting a carbon neutral portfolio for all
customers using either environmental offsets or physical biogas. The four main options
discussed by the UAC at its June 1, 2016 meeting are summarized in Table 2 below.

“slamming” or even taking advantage of
customers who are not paying attention
even after being notified of right to opt-
out
Requires ongoing outreach to notify
customers of their ability to opt-out at any
time
Requires development of detailed
program rules and processes to allow for
opting out/in, securing refunds and
identifying potential sources of funds for
such refunds.

UAC Action on June 1, 2016
On June 1, 2016, the UAC discussed the alternatives to continuing PAG Gas as a voluntary opt-in
program and generally agreed that the current opt-in model was the least desired option.
The UAC discussed the incremental cost of biogas and the availability of environmental offsets
and said that, if the long-term goal was to have a carbon neutral gas portfolio, it would not be
advisable to first convert the program to an opt-out program and then move to a carbon
neutral portfolio since it would look like there was an opt-out option, but then that option
would be taken away. One suggestion was to start with a portfolio that is not 100% carbon
neutral and transition to 100% carbon neutral over time. Another suggestion was to start with
offsets first and move to add more biogas over time. However, at the June 1, 2016 meeting,
the UAC was not presented detailed costs for the different alternatives.
One commissioner expressed support for converting to an opt-out program and advised against
introducing a new program that costs more when gas rates are increasing as shown in the long-
term Gas Financial Plan.
At its June 1, 2016 meeting, the UAC voted 6-1 (with Chair Cook, Vice Chair Danaher, and
Commissioners Ballantine, Forssell, Johnston and Trumbull voting yes and Commissioner
Schwartz opposed) to recommend that Council adopt a carbon neutral gas portfolio and direct
staff to develop an implementation plan. The minutes from the UAC’s June 2016 meeting are
provided as Attachment C.
Discussion
To design and implement a carbon-neutral gas portfolio plan, several inter-related variables
must be considered, including:
1. Rate impact.
2. Supply source (environmental offsets or biogas).
3. Timeframe over which carbon neutrality is achieved
4. Percentage of the portfolio to be made carbon-neutral.
With respect to each of the variables above, staff makes the following recommendations:
1. Rate impact: No greater than 10¢/therm annually
2. Supply source: Combination of environmental offsets and biogas, with exact mix
designed to maximize carbon neutrality within established rate impact limit. Staff
estimates approximate ratio of offsets (95%) to biogas (5%) at the outset of the
program.
3. Timeframe over which carbon neutrality is achieved: By FY 2018
4. Percentage of portfolio made carbon neutral: 100%
City of Palo Alto Page 10
Rate Impact
Staff recommends that Council make a clear determination of acceptable rate impact for a
carbon-neutral gas portfolio. Council took such a step with respect to Carbon Neutral Plan for
electricity where rate impacts, for a variety of reasons, were expected to be less significant than
those potential impacts from a carbon free gas portfolio. The rate impact of achieving carbon
neutrality for the electric portfolio is quite small (on the order of 1-2%) because the
incremental cost to get to carbon-neutrality is diminished by the significant RPS requirement
and the fact that carbon-free hydroelectric supplies provide about half of the City’s energy
requirements in a normal year. The rate cap for the carbon neutral electric portfolio established
by Council is 0.15 cents per kWh (Staff Report 3550, Resolution 9322).
By contrast, the costs associated with a carbon neutral gas supply and associated rate impacts
are not likely to be as low. The gas portfolio is currently supplied 100% by a fossil fuel source,
whereas the electric supply portfolio includes a large fraction of carbon-free hydroelectric
supplies and is subject to the State requirement for renewable supplies to meet a minimum of
33% (now 50% by 2030) of the City’s needs. A rate impact of 10 ₵/therm is equal to
approximately a 10% rate increase based on current gas rates and assuming a commodity rate,
which fluctuates monthly with market prices, of 30 ₵/therm.
Supply Source
Offsets as Supply Source
Using environmental offsets to neutralize the GHG emissions of the gas portfolio is significantly
less expensive than buying biogas. If environmental offsets were purchased today for 100% of
the City’s gas usage, all customers would experience a rate increase of approximately 4%. A
residential customer’s winter bill would increase by about $2 per month (about $0.75 in the
summer). A range of potential offset costs were analyzed and are presented in Figure 4 below.
The current cost of offsets is about $8 per ton of CO2e, which is equivalent to 4 ₵/therm.
City of Palo Alto Page 11
Figure 4: Rate and Bill Impact of Using 100% Offsets to Achieve Carbon-Neutrality
Biogas as a Supply Source
Alternatively, the City’s gas needs could be met with renewable physical biogas, a much more
expensive option.
Biogas is a product of organic conversion (from cow manure at a dairy farm or from a landfill,
for example). Most biogas produced in the United States is used as either a transportation fuel
or to generate electricity. Biogas is most valuable as a transportation fuel due to the Federal
Renewable Fuel Standard program and the state regulations like California’s Low Carbon Fuel
Standard (LCFS) and Renewable Portfolio Standard (RPS). Biogas converted to electricity may be
used to meet California’s RPS compliance obligations for electric utilities. State regulation and
pipeline interconnection costs have largely kept biomethane projects out of California, but out-
of-state supply sources are available.
The short-term price for biogas is in the $2-$3 per therm range due to the transportation fuel-
driven demand mentioned above. For a longer-term fixed-price commitment (5-7 years), prices
are discounted to around $1.50 per therm. Two things eliminated the consideration of biogas
for the City’s voluntary PAG Gas program: (1) the cost and the incompatibility between a
voluntary program with uncertain demand; and (2) the biogas project developers’ need long-
term commitments. While cost is still an issue, if it decided to pursue a carbon-neutral portfolio
for the long term, the City would be in a position to make a long-term commitment for biogas.
At a biogas price of $1.50/therm (or $1.20/therm over the projected $0.30/therm cost for
natural gas), supplying 100% of the portfolio with biogas results in about a 120% rate increase
City of Palo Alto Page 12
or about $65 more per month on an average residential customer’s monthly winter bill (or
about $22 per month more in the summer when average residential use is 18 therms/month).
Figure 5 shows both the rate and bill impacts at various biogas prices.
Figure 5: Rate and Bill Impact of Using 100% Biogas to Achieve Carbon-Neutrality
The two supply sources, environmental offsets and biogas, could be combined to achieve
carbon-neutrality. However, even a ratio of 5% biogas and 95% environmental offsets results in
a rate impact greater than 10%. Figure 6 shows the rate and bill impacts for different
percentages of the two supply resources using biogas costing $1.50/therm and environmental
offsets costing $8 per ton.
City of Palo Alto Page 13
Figure 6: Rate and Bill Impact of Using a Combination of Biogas and Offsets to Achieve
Carbon-Neutrality (Assumes $1.5/therm Biogas & $8/ton Offsets)
Carbon Neutrality: Portfolio Percentage & Timeframe
Two other variables may be adjusted when designing a carbon neutral plan. To reduce the cost
impact of buying green gas for the gas portfolio and the GHG emissions reductions only a
portion of the portfolio could be made carbon neutral. Alternately, or in addition, a green gas
portfolio standard could increase over time (e.g. start at 10% in FY 2018 increasing to 100% by
FY 2021).
Figure 7 shows the rate and bill impacts of various biogas to offset ratios if less than 100% of
the portfolio is carbon-neutral. Again, a $1.50/therm biogas price and an $8 per ton
environmental offset price are assumed.
City of Palo Alto Page 14
Figure 7: Rate and Bill Impact of Using a Combination of Biogas and Offsets to Achieve Partial
Carbon-Neutrality (Assumes $1.5/therm Biogas & $8/ton Offsets)
Summary of Proposal
The proposed plan will use a combination of physical biogas and high-quality environmental
offsets to achieve a carbon-neutral gas portfolio by FY 2018. The amount of biogas included in
the portfolio will be maximized while causing rates to increase by no more than 10 ₵/therm.
Given the 10 ₵/therm rate impact cap and current market prices, approximately 5% of the City’s
portfolio can be met with biogas with the remaining 95% neutralized with environmental
offsets.
If the price of offsets increases, the portfolio may need to comprise up to 100% offsets, or the
portfolio may be less than 100% carbon neutral. On the other hand, if the price of offsets
decreases, the proportion of biogas will increase. Purchasing biogas for less than 5% of the total
portfolio demand may be too small for a transaction. In that case, the portfolio will be
comprised of 100% offsets, and the rate impact with be significantly less than 10 ₵/therm.
Cost-effectiveness of a Carbon-neutral Gas Portfolio Compared to Electrification
In May 2015, the UAC reviewed a cost effectiveness study for abating GHG emissions by
electrifying building appliances and passenger vehicles. The report was provided to Council in
August 2015 (Staff Report 5971). Figure 8 shows the societal costs of carbon from that study
compared to the carbon cost of environmental offsets and biogas. The estimated cost of
$1.50/therm for biogas, or an incremental cost of $1.20/therm relative to brown gas, results in
an incremental cost of carbon of $226 per ton of CO2e. Environmental offsets are assumed to
cost $8/ton of CO2e.
City of Palo Alto Page 15
Figure 8: Incremental Societal Abatement Cost
As shown in Figure 8, environmental offsets are a much less expensive way to achieve carbon
reductions compared to most electrification options5. Biogas, however, results in higher
abatement costs than converting from natural gas-fired water and space heaters to electric
heat pump water and space heaters and converting from a gas stovetop to an electric stovetop.
Proposed Biogas and Offset Criteria for Carbon-neutral Gas Supply
Offset Criteria – Same as Approved for PAG Gas
For the PAG Gas program, Council approved the use of high-quality environmental offsets from
protocols approved by the California Air Resources Board. The approved protocols currently
include forestry, livestock, landfill, coal mine methane, urban forestry, ozone depleting
substance and rice cultivation projects. Offsets used for PAG Gas do not need to be certified by
CARB as it is an extra expense and only necessary if offsets are to be used for a regulatory
compliance obligation. Staff proposes to apply the same standards to offsets used for the
Carbon Neutral Gas Plan including a preference for California and local projects (Staff Report
4596, Resolution 9405).
Biogas Criteria – “Displacement” Concept Allowed
Biogas is generated from an organic source such a waste from a dairy farm, other agricultural
waste or from a landfill. Very little biogas is produced in California, but the Environmental
Protection Agency’s (EPA) Renewable Fuel Standard Program is driving the development of
projects in other states. The EPA recognizes two things: (1) molecules of biogas go into the
pipeline and rarely end up being burned by the purchaser of that gas and (2) gas transportation
5 The study concluded that (after federal and state incentives) it is cheaper to own and operate a compact electric
car (Nissan Leaf) than a similarly sized gasoline vehicle (Honda Civic) resulting in a negative incremental abatement
cost.
City of Palo Alto Page 16
can add significant costs if a biogas purchaser is forced to move gas long distances. The EPA,
therefore, allows for “displacement” whereby biogas is purchased at a point near the project
site and the environmental attributes of that gas are attached to brown gas delivered at a
different location. California’s RPS program, on the other hand, requires entities to contract for
gas transportation from the biogas source to the end use, adding significant cost to the gas.
Because the City is seeking ways to reduce its GHG emissions and is not using offsets or biogas
to meet a compliance obligation, the City has latitude to establish its own criteria for biogas use
and eligibility under the City’s carbon-neutral gas supply program. Staff recommends utilization
of the EPA’s approach, which allows for displacement of biogas in one location for brown gas in
another location under the City’s carbon-neutral gas program.
Alternatives
There are many alternatives to the proposed program, which can be described by varying the
key determinants. The following examples are ways in which the plan can be modified.
1. Rate impact: A rate impact higher than 10 ₵/therm would result in more biogas versus
offsets being part of the portfolio. If the rate impact limit was reduced, the portfolio may
not be able to be 100% carbon neutral. As another alternative, the rate impact could
increase over time—for example, starting out at 5 ₵/therm and increasing to 10 ₵/therm in
five years.
2. Supply: The proposed plan includes a combination of biogas and offsets such that the
amount of biogas is maximized while limiting the rate impact to a set amount (10 ₵/therm).
Instead of a rate impact measure, the program could be developed with a prescribed ratio
of biogas to offsets. In this case, the rate impact would depend on the cost of the offsets
and the biogas and could change year to year.
3. Carbon-neutral coverage of the portfolio: The proposed plan uses the full 10 ₵/therm to get
up to 100% carbon neutrality with the expectation that most (95%) of the supply will be
environmental offsets with the balance being biogas. However, the goal could be less than
100% carbon neutral supplies—for example, the goal could be to achieve 50% carbon
neutral supplies while under the 10 ₵/therm rate impact, which would allow for purchases
of biogas for about 8% of the gas needs and offsets for about 43% of the gas needs given
current prices for offsets and biogas supplies.
4. Timing: The most aggressive implementation schedule, by FY 2018, is recommended.
Carbon-neutrality could be staged over any number of years with changing rate impact or
changing proportion of offsets to biogas.
These program attributes could be combined in any number of ways to develop a program as
shown in Table 5 below.

Commission Review and Recommendation
Staff presented the proposed Carbon Neutral Gas Plan to the UAC at its August 31, 2016
meeting. Commissioners asked if the gas that would be neutralized by buying offsets or
replaced with biogas accounts for all the gas the City uses in addition to whatever is leaked
from source to transportation to the distribution system. Staff explained that the gas needs
were determined by what the City buys at the Citygate and it includes any gas leaked in the
City’s gas distribution system, but not any leaks in the gas transportation system or at the gas
source. The greenhouse gas emission calculation is based on accounting for the gas at the
Citygate as if it was 100% burned and not leaked as methane.
Commissioners generally indicated they liked the flexibility of the proposed program since it
provides for a higher amount of biogas as the cost comes down and it supports the
development of a biogas marketplace. Commissioners also discussed whether carbon neutral
gas would dampen the enthusiasm for electrification and asked if carbon neutral electricity has
dampened the penetration of rooftop solar.
After discussion and hearing public comment, the UAC voted to recommend Council approve
the plan (6-1 with Chair Cook, Vice Chair Danaher, and Commissioners Ballantine, Forssell,
Johnston, and voting yes and Commissioner Schwartz voting no). The minutes from the UAC’s
August 31, 2016 meeting are provided as Attachment D.

Resource Impact
Implementation of a carbon-neutral gas portfolio will increase retail rates (and revenues) and
the gas commodity budget. The recommendation is to cap the rate impact at 10 ₵/therm. At
that level, commodity costs will increase by about $3 million, from $9 million to $12 million, per
year. The retail rate revenue will likewise increase by $3 million. If the program is approved, the
increased cost and revenues will be reflected in the FY 2018 budget request.
A rate increase of 10 ₵/therm will increase rates by approximately 10%. For the median
residential customer using 18 therms per month in the summer and 54 therms per month in the
winter, the bill impact will be $1.80/month in the summer and $5.40/month in the winter, or
about $43 per year.
Policy Implications
The Council-approved Utilities Strategic Plan includes an objective to offer programs to meet
the needs of customers and the community.
Strategy 4 in the Council-approved GULP states:
Reduce the carbon intensity of the gas portfolio in accordance with the Climate
Protection Plan by:
a. Designing and implementing a voluntary retail program using reasonably
priced non‐fossil fuel gas resources; and
b. Purchasing non‐fossil fuel gas for the portfolio as long as it can be done with
no rate impact.
Implementation of a carbon-neutral gas portfolio represents a departure from GULP Strategy 4
because the voluntary program will be eliminated and there will be a rate impact resulting from
non-fossil fuel gas resources being purchased for the portfolio. GULP will need to be revised
accordingly should Council approve a carbon-neutral gas portfolio.
A carbon-neutral gas portfolio would, however, be an important part of meeting Council’s
aggressive goal to reduce the City’s GHG emissions by 80% by 2030.
Next Steps
Several tasks must be completed before implementing the proposed Carbon Neutral Gas Plan.
For example, existing gas purchasing agreements may be used to procure biogas with details
about the biogas added to the transaction confirmations. Environmental offsets for the current
PAG Gas program are included in the City’s agreement with the program administrator, so new
contracts may need to be developed to purchase offsets for the carbon-neutral portfolio. If the
Carbon Neutral Gas Plan is approved by Council, staff will execute enabling agreements with
qualified counterparties for purchasing environmental offsets.
City of Palo Alto Page 19
In addition, new rate schedules will be developed and brought to the UAC and Finance
Committee for recommendations and to the Council for approval. Staff anticipates that this can
be achieved such that the gas portfolio can be implemented in FY 2018.
Because implementation of a carbon-neutral gas portfolio represents a departure from the
Council-approved GULP strategies, GULP will need to be revised before the program is put into
place.
Cancelling PAG Gas will require communication with the customers, repeal of the rate schedule
via resolution, and removal of the charge on participating customers’ bills by the carbon-neutral
implementation date.
Environmental Review
The Council’s adoption of a resolution implementing a carbon-neutral gas portfolio and
terminating the PaloAltoGreen Gas Program does not meet the definition of a project, pursuant
to section 21065 of the California Environmental Quality Act (CEQA). Offset and biogas project
developers will be responsible for performing necessary environmental reviews and acquiring
permits as offset and biogas projects are developed.

Resolution No.
Resolution of the Council of the City of Palo Alto Approving a
Carbon Neutral Natural Gas Portfolio Plan to Achieve Maximum
Carbon Neutrality Using a Combination of Offsets and Biogas in
the Gas Supply Portfolio by Fiscal Year 2018 with No Greater than
10¢/Therm Rate Impact; and Related Termination of the Palo Alto
Green Gas Program
R E C I T A L S
A. In December 2007, Council adopted the City’s Climate Protection Plan which set
aggressive greenhouse gas (GHG) emission reduction goals to be achieved by the year 2020.
B. In March 2013, this Council approved Resolution 9322 directing staff to achieve
carbon neutrality for the electric supply portfolio by 2013 through the use of a combination of
hydroelectric resources, long-term renewable resources and short-term renewable energy
resources and/or renewable energy certificates (“RECs”).
C. On September 9, 2013, this Council approved Resolution 9372 modifying and
suspending portions of the PaloAltoGreen Program, and directing staff to develop a
PaloAltoGreen Gas (PAG Gas Program) Program.
D. On April 21, 2014, this Council approved Resolution 9405 establishing the voluntary
PAG Gas Program to provide the opportunity for residential and commercial customers to
economically reduce or eliminate the impact of GHG emissions associated with their gas usage
through the purchase of certified environmental offsets.
E. In April 2016, this Council adopted a GHG reduction goal of 80% by the year 2030.
GHG emissions associated with natural gas use were 135,000 metric tons of carbon dioxide
equivalent, or 27% of the City’s GHG emissions, in 2015.
F. The Carbon Neutral Gas Plan uses a combination of physical biogas and high-quality
environmental offsets to achieve a carbon-neutral gas portfolio by fiscal year 2018 by
maximizing the amount of biogas in the portfolio while holding the rate impact to ten cents per
therm (10 ₵/therm).
G. On August 31, 2016, the Utilities Advisory Commission voted 6-1 to recommend
Council approve the proposed Carbon Neutral Gas Plan and terminate the PAG Gas Program.
The Council of the City of Palo Alto RESOLVES as follows:
SECTION 1. The Council hereby adopts the resolution:
Attachment A
NOT YET APPROVED

1.Approving a Carbon Neutral Gas Plan, enabling the City to achieve a carbon-
neutral gas supply portfolio starting in fiscal year 2018 with a rate impact not to exceed ten
cents per therm (10 ₵/therm); and
2.Terminating the PaloAltoGreen Gas program established by Resolution 9405.
SECTION 2. The Council’s adoption of this Resolution, which implements a carbon
neutral gas portfolio and terminates the Palo Alto Green Gas program does not meet the

EXCERPTED FINAL MINUTES OF THE OCTOBER 7, 2015
UTILITIES ADVISORY COMMISSION MEETING
ITEM 2. DISCUSSION: Conversion of the PaloAltoGreen Gas Program From an Opt-In to an
Opt-Out Program
Chair Foster noted that this item is on the agenda due to support for the idea expressed from
members of the community.
Public Comment
Sandra Slater commended the commission for keeping sustainability on the agenda. She said
that it's time to move the needle now. She noted that research shows that participation will be
much higher if the program was converted to an opt-out program. She said that the program
could be changed to make the program supportable by all income levels. Converting the
program to an opt-out program is something the City could do that would have an immediate,
positive impact.
Lisa Van Dusen said that the program is not perfect since it is backed by offsets, but we
shouldn't let the perfect be the enemy of the good. We could pay even more by purchasing
more aggressive offsets. There could be mechanisms to get out of the program during an
"amnesty period" and low income customers on the Rate Assistance Program could be retained
as opt-in customers. She said that there was so much staff effort for the PaloAltoGreen
(electric) program just to achieve 24% participation and that there would be savings from lower
marketing and administration costs in an opt-out program.
Chair Foster said that the money paid by PaloAltoGreen Gas (PAGG) program participants fund
offsets that pay to convert waste into methane that is burned to produce renewable electricity
at a dairy farm in Wisconsin and that this wouldn't be done without the revenue from the
offsets. Assistant Director Jane Ratchye indicated that this is correct. She said that the offsets
that back this program are very high quality as they are selected only from those protocols that
have been certified for use in the state’s cap-and-trade auction by the California Air Resources
Board. One of the requirements of those protocols is that the offset be “additive”, or from a
project that would not have been done without the monetary support from the sale of the
offsets. Chair Foster said that he supports an opt-out program and that the additional cost is
only $5 to $6 per month for the average resident.
Commissioner Ballantine noted that there are ongoing costs to maintain an anaerobic digester.
He said that people who opt-in are causing something real to happen. The greenhouse gas
emissions reductions from those sources would not otherwise happen without programs like
PAGG.
Vice Chair Cook noted that the PaloAltoGreen (PAG) Electric program was effectively converted
to cover everyone via the carbon neutral program and was a great way to transfer the new
goal. He asked why PAGG was not made an opt-out program originally. Vice Chair Cook added
that Community Choice Aggregation (CCA) programs were successful because they were opt-
out programs. Ratchye replied that the carbon neutral electric supply is not the same as PAG
and that it was not developed as a transition from PAG. She noted that PAG purchased
Renewable Energy Certificates (RECs) for 100% of a residential customer’s load at a cost of 1.5
cents/kWh, or about 12% more than the normal electric rate. On the other hand, the carbon
neutral electric supplies consist of about half carbon-free hydroelectric supplies, renewable
supplies that are eligible under the state’s Renewable Portfolio Standard (RPS) and that RECs
are purchased for the balance of the needs. It is expected that by the end of 2016, the City’s
RPS will be 57% and with hydro supplies (given a normal hydro year), no RECs will be needed
for carbon neutral electric supplies. She said that the state’s new goal for an RPS of 50% would
result in carbon neutrality anyway at no additional cost in a normal hydro year. However, the
increased cost of PAGG for participants is 12 cents per therm, or about 12% more than the
normal gas rate of about $1 per therm. She said that the additional cost for PAGG was a
consideration for making the program an opt-in program like PAG when the program was
originally conceived. In addition, the program was just launched in January 2015 (and has yet
to roll out a comprehensive marketing campaign for the program) and staff was hoping to
determine the community’s appetite for the program. Ratchye agreed that CCAs are successful
opt-out programs, but that they are generally no more costly than the alternative from the local
utility so participants are not paying any extra to be “slammed” into a CCA.
Vice Chair Cook said that our rates are allowed to go up with the carbon neutral electric
supplies and asked what the threshold is for an opt-out versus an opt-in program.
Chair Foster replied that the comparison of PAGG to the carbon neutral plan is different—like
apples and oranges—since the carbon neutral electric supplies is not an opt-out, or opt-in,
program, but is the electric supply for all customers. The percentage increase in cost to electric
rate payers by going carbon neutral is small compared to the percentage increase to a customer
by paying for participation in PAGG. He said that PAGG should be compared to the PAG electric
program.
Chair Foster asked if there is any legal reason that City Council could not adopt an opt-out
program. Senior Deputy Assistant City Attorney Jessica Mullan said that a legal analysis would
have to be completed and the answer may depend on the program design.
Commissioner Schwartz asked if the point of the program was to reduce gas use or raise
revenue. Chair Foster responded that neither of those options is the point, but that the
objective is to reduce greenhouse gas (GHG) emissions associated with customers’ gas use.
Commissioner Schwartz said that she agreed that more people will do an opt-out program, but
that we need to make sure that participants truly want to participate. We need to provide a
very easy way for people to opt-out and not be penalized for any of the months they were
enrolled if they don’t want to be. A good outreach campaign could be a good way to increase
awareness of the issue and it could have an impact of increasing customers’ awareness. She
said that the program could be a bridge for people to become more conscious of using energy
and would not just be a way to buy ourselves out of the problem.
Commissioner Hall suggested that we not act too hastily, but develop a program like this over
time, similar to the carbon neutral portfolio adoption. He said that he suspects that there
would be a percentage of consumers that would find out later that they were enrolled in a
“voluntary” program and feel cheated. A way forward could be to develop a carbon negative
plan and start with a surcharge that would fund a solution to global warming. He said it could
be a program that would be broadly advertised to ensure that everyone would be aware of the
program.
Commissioner Schwartz noted that she had seen an effective “cow power” video, which is an
example of how the communication can be done in a playful way that would let people
understand that we are in this together, which is a compelling message for many people. She
added that it would be a good messaging experiment.
Commissioner Eglash thanked the public commenters. He also complimented the UAC for
placing the item on the agenda and allowing this discussion to take place. Commissioner Eglash
said that when he weighs the advantages and disadvantages of opt-in versus opt-out, he would
like to avoid disgruntled customers and any worry about customer satisfaction. The greatest
danger of an opt-out plan is potential customer dissatisfaction. We devote a lot of time to
customer satisfaction with the utility. He said it is more risky in this respect and as the price
becomes significant, the danger becomes worse. He said that, with a full marketing campaign,
is it still plausible that people would not be in the program that wouldn't want to be. He added
that perhaps a very successful campaign would result in the same participation of an opt-out
and an opt-in program. Commissioner Eglash indicated that he is leaning towards maintaining
PAGG as an opt-in program. He added that there should be no action on the item at this time
since there is no staff analysis, no fiscal analysis or legal analysis completed at this time. The
discussion is conceptual at this point; there is no proposed design for an opt-out program.
Chair Foster indicated that he disagrees that the participation rates for opt-in versus opt-out
will converge with a great marketing campaign. He added that this is a discussion item on the
agenda tonight so no action can be done.
Commissioner Schwartz said that customer satisfaction depends on transparency. The fact that
CPAU cares about being green will show that an opt-out program is consistent with the brand.
She added that safeguards to allow folks to opt-out will be consistent with transparency.
Commissioner Eglash said that many people in Palo Alto take pride in the City’s environmental
efforts. He stated that safety, reliability, and low cost are primary considerations and to impose
a greener solution that costs extra money is hazardous and must be done carefully.
Commissioner Ballantine noted that offset resources are finite and that pressures from supply
and demand will eventually bite us as the price for offsets will increase as demand increases.
He added that an opt-out program would require sufficient offsets to be supplied.
Commissioner Danaher said that the PAGG program has an environmental benefit, a
psychological benefit, and a moral benefit. He said that the best idea is to make the program
neither opt-in or opt-out, but our gas supply for everyone. He added that an opt-out program
still allows people to opt-out easily since it could be very easy to go to the website and opt out.
Commissioner Hall said that we could conduct a poll to see what the customers’ response
would be to an opt-out program. He said that we should want to have this information before
making a decision.
Commissioner Schwartz advised against a poll as it would defeat the purpose of communicating
the benefits of an opt-out program. Commissioner Danaher added that the poll would only be
answered by the small number of people who read and respond to email.
Commissioner Foster said that the program could be designed so that anyone who failed to
opt-out early enough could still get their money back. He asked if the UAC could make a
motion to recommend that the Council direct staff to develop an opt-out program. Director
Fong stated that it can be added to the rolling calendar. Mullan added that the item is
agendized as a discussion item and that the Commission can add it as a future item to be
agendized under Item 4 on this meeting’s agenda.
Vice Chair Cook thanked the public commenters. Commissioner Hall added his appreciation of
the input from the public commenters, even if some commissioners disagree.

EXCERPTED FINAL MINUTES OF THE JUNE 1, 2016
UTILITIES ADVISORY COMMISSION MEETING
ITEM 2. ACTION: Utilities Advisory Commission Discussion on Alternatives to the Existing
Voluntary Opt-In PaloAltoGreen Gas Program Including an Opt-Out Mechanism and a Carbon-
Neutral Natural Gas Portfolio
Senior Resource Planner Karla Dailey summarized the written report.
Commissioner Schwartz asked why is was so expensive just to convert from opt-in to opt-out
since the rate is not being changed. Dailey explained that changes to the billing system made up
the bulk of costs. Dailey pointed out that, after the initial investment, administrative costs drop
significantly for the opt-out program. Commissioner Schwartz stated that the cost estimate
seemed very high and questioned the advisability of making changes to the billing system,
which is planned for replacement.
Interim Director Shikada said the timing of an opt-out program should take into account the
legacy billing system.
Commissioner Trumbull asked about the bill impact. Dailey confirmed the bill impact is only for
those customers in the voluntary program.
Commissioner Ballantine asked about the customer breakdown. Dailey said 50% is residential,
30% is small commercial and 20% is large commercial.
Commissioner Forssell asked about the variability for a typical residential customer. Dailey said
some residential customers probably have much higher bills.
Dailey described the types of customers with respect to an opt-out program structure: active
supporters, passive supporters, unaware supporters, ambivalent customers, unaware
opponents, passive opponents, aware opponents and active opponents. Dailey said staff is
concerned about the customers who would be opposed to an opt-out structure, but do not opt-
out right away for whatever reason leading to resentment and poor customer relations at a
later date as well as issues around refunding the PAG Gas fee should a customer demand that.
Commissioner Schwartz said that bill impact was so small that it shouldn’t cause harm to most
customers and, if it was easy to opt-out, an opt-out program shouldn’t be a problem for
anyone. If there were customers that found out later and were mad, the program could be
designed to allow for refunding those customers. Dailey said that this is problematic.
Commissioner Schwartz said that the risk to consumer attitude seems not to be a large issue.
Continuing with the presentation, Dailey said that another option is to convert all, or a portion
of, the natural gas portfolio to carbon neutral supplies.
Commissioner Johnston asked if there would be any mechanical issues with running biogas
through the pipeline. Dailey said that there would be no problem since biogas must meet the
pipeline quality standards. Commissioner Ballantine added that the quality requirements
depend on whether the gas is used for generation directly, or put in the pipeline—and the
biogas can be mixed with natural gas to meet the pipeline quality standards.
Chair Cook asked how the $1/therm incremental cost of biogas compared to the cost of natural
gas. Dailey said that the current commodity cost of natural gas is about 20 cents per therm.
Commissioner Johnston asked if there were limits to the number of offsets available. Dailey
said that there would be sufficient offsets for our portfolio.
Chair Cook asked staff to describe the offsets. Dailey said that the protocols for the offsets are
all California Air Resources Board approved although the offsets themselves are not CARB
certified. She explained the extra CARB certification would be needed for offsets used for
compliance purposes rather than a voluntary program.
Public Comments
Sandra Slater stated that she and Lisa Van Dusen have prepared a letter with comments on the
issue. She said that she supports the opt-out program, but her favorite is to have the gas
portfolio carbon neutral. She said that climate change is a huge problem and time is getting
short. She said that offset purchases can be a bridge in a plan to purchase biogas. She said that
the success of the PaloAltoGreen program proves that there is large support for such a
program. She also referenced the 80% GHG reduction goal by 2030 Council directive. She
advised that we need to wean ourselves off of fossil fuels and move to electrification. She said
there will be a few people, maybe as many as a hundred, who will be opposed, but a small
number of people should not dictate the direction of the utility. She said that it would be nice
to have local offsets, but supporting methane capture projects outside of Palo Alto is valuable
since we have a global problem.
Lisa Van Dusen said that the main point is that there is fundamental responsibility to take
control of the impact caused. She advised that the City should take a bold action, noting that
nothing is perfect. The goal is to maximize carbon reductions, minimize the potential for
grumbling customers, minimize the impact to ratepayers, and allowing customers to have a
choice. She said that higher gas prices also acts to encourage additional gas use efficiency.
Commissioner Johnston said that the City should move away from the opt-in program design
and advised that it should be easy for customers to opt out of the program.
Commissioner Ballantine supported the option of moving to a carbon neutral gas portfolio,
rather than transitioning to an opt-out program. He said that during the rate adjustment
process, the larger users had a smaller percentage impact than the lower using customers,
which is due to the fixed costs to operate the system. He said that it is not free to have a carbon
neutral electric portfolio. He said that the move to electrification may be problematic if the
electric portfolio is carbon free, but the gas portfolio isn’t.
Commissioner Forssell asked if he program would only apply to residential customers only. She
asked if we first go to an opt-out program and allow customers to opt out, then transition to a
portfolio could be a problem since you first allow them out, then force them in. She said that
we could start with carbon neutral portfolio that is not 100%, but could transition there over
time.
Commissioner Schwartz said that all points of view are represented in Palo Alto. She said that
she is in favor of an opt-out program since this is an opportunity to practice how to do that. If
there is no way to opt out, this could be a problem for some customers who will create a large
issue in the community as it has been elsewhere with respect to having smart meters.
Commissioner Trumbull said he did not opt-in to the current program. He was also concerned
about opt-out as a transition to carbon-neutrality.
Vice Chair Danaher said he stated at the prior UAC meeting on the subject that he was
supportive of a carbon neutral gas portfolio and, after seeing the analysis, he is even more
supportive of that option. Danaher asked if there was any negative feedback for the carbon
neutral electric portfolio. Assistant Director Jane Ratchye said that there was no negative
feedback that she knew of regarding the carbon neutral electric portfolio. Vice Chair Danaher
said that there could be a cost for morality and that he supports moving to a carbon neutral
portfolio rather than moving to an opt-out program.
Chair Cook asked Chief Sustainability Officer Gil Friend whether the choices would support the
City’s carbon goals. Friend noted that natural gas represents 25% of the City’s GHG emissions.
Interim Utilities Director Ed Shikada noted that there was no staff recommendation for this
item and views this discussion as one of values. He said that a survey of the community could
be done to determine the community’s view on the issue.
Chair Cook noted that staff did not provide a recommendation as it usually does and said he
thought that this was appropriate in this case. He stated that we are talking about this at a time
when gas rates are very low and also at a time when rates across the board are rising
significantly this year. He said that he had not heard any protest regarding carbon neutrality for
electric supplies, but says that a transition to carbon neutral gas can start and increase over
time. It would be perhaps most advisable to start with offsets first and move to renewable
biogas over time. He would recommend #3 and move to #4 by 2030. He would like to see the
costs for these options.
Commissioner Schwartz said that the issue with smart meter rollout happened when there
were many missteps caused by a rate increase, very hot weather and the new meters were
blamed. She said that rising rates are not a good time to introduce a new program that costs
more. The downside is that the program could fail spectacularly if it becomes the rallying point
for complaints.
Commissioner Schwartz advised that a survey could be taken to determine the level of support.
Chair Cook said he appreciated the additional options presented by staff. He pointed out that
gas prices are currently very low and rates in the five utilities are increasing. Chair Cook said he
was not prepared to adopt a carbon-neutral program supplied with only biogas. He said the
rate impact would be less than the opt-in or opt-out options for a carbon-neutral portfolio.
Dailey confirmed that administrative costs for the portfolio are near zero. He said he prefers
starting with offsets and slowing adding biogas to the carbon-neutral portfolio. Chair Cook
recognized that there will be some complaints but said the rate impact is low and the impact of
a carbon-neutral portfolio is high.
Commissioner Trumbull stated that he was supportive of having more detail available for a
program before going to Council with a final recommendation.
ACTION:
Vice Chair Danaher made a motion that the UAC recommend that Council adopt a carbon
neutral gas portfolio and direct staff to develop an implementation plan. Commissioner
Trumbull seconded the motion. The motion passed (6-1) with Chair Cook, Vice Chair Danaher,
and Commissioners Ballantine, Forssell, Johnston and Trumbull voting yes and Commissioner
Schwartz opposed.
Vice Chair Danaher left the meeting at the conclusion of the discussion of item #2.
ATTACHMENT D
EXCERPTED DRAFT MINUTES OF THE AUGUST 31, 2016 – SPECIAL MEETING
UTILITIES ADVISORY COMMISSION MEETING
ITEM 2. ACTION: Recommendation that Council Approve a Carbon Neutral Natural Gas
Portfolio Plan to Achieve Maximum Carbon Neutrality Using a Combination Of Offsets and
Biogas in the Gas Supply Portfolio by Fiscal Year 2018 with No Greater than 10¢/Therm Rate
Impact; and Related Termination of the Palo Alto Green Gas Program
Senior Resource Planner Karla Dailey provided a presentation summarizing the written report.
Chief Sustainability Officer Gil Friend said that the Sustainability/Climate Action Plan (S/CAP)
includes a plan to get to a carbon neutral utility and an aspirational goal of a carbon neutral
city. He said that moving to an electrified city will be a long and complex process. He said the
proposed program is a bridge to using less natural gas and that a comprehensive approach
including offsets, biogas, efficiency and electrification will be necessary to achieve the city’s
long-term goals. He pointed out that buying offsets provides capital for more projects in the
U.S. and potentially locally.
Public Comment
Sandra Slater said that proposal is an interim strategy to get to carbon neutrality as soon as
possible and offsets are a good tool to use for the time being. The price signal that the program
cost provides will encourage gas efficiency and electrification of gas appliances. She suggested
the money currently used to market the voluntary program could be redirected to efficiency
and fuel switching programs. Offsets are not a “pass” for consumers as evidenced by the fact
that Palo Altans continue to conserve electricity despite the carbon neutral electric supplies.
Lisa van Dusen said that we must do everything and the beauty of this is that it can be done
now and shows an intention to reduce carbon emissions in the long term. We have policies in
place such as the 2009 proclamation to include environmental externalities and the S/CAP goal
to reduce greenhouse gas (GHG) emissions by 80% by 2030. It may be faulted as not enough or
too much, but it’s a good move in the right direction.
Vice Chair Danaher said that the UAC received a comment from a member of the public who
pointed out the proposed offset purchases do not cover fugitive methane losses from natural
gas production and transportation. Vice Chair Danaher added that methane is as bad as coal
due to the fugitive emissions. Commissioner Ballantine said that that position is not reflected in
any DOE report that he searched for. Commissioner Schwartz agreed that the coal and natural
gas are not considered to be equally bad by industry experts.
Vice Chair Danaher said the proposed program is a good starting point and asked about the
value of purchasing biogas. Dailey confirmed biogas is more expensive than offsets and it is
Council’s prerogative to decide whether biogas is worth including. Commissioner Danaher
asked where the methane comes from. Dailey explained the gas comes from landfills and
agriculture, mainly dairy farms.
Commissioner Ballantine said that if the source is dairy farms, then avoided methane emissions
need to be considered. Dailey explained that offsets are generated by preventing methane
from entering the atmosphere and the resulting biogas is a renewable fuel. A specific project
can produce both offsets and renewable biogas.
Commissioner Trumbull said that the request is fine, but he would like to get off gas as soon as
possible. He suggested that rather than buying biogas, extra funds be used for electrification.
Commissioner Johnston asked about the monthly bill impact of the 10 cent per therm rate
increase. Dailey answered that an average residential customer’s winter bill would increase by a
little more than $5 per month and pointed to a chart in the written report with the detail.
Commissioner Forssell clarified the proposed amount of carbon to be covered by offsets is only
that combusted in town and does not include methane leakage from the production fields or
leaks in the transportation system. Assistant Director Jane Ratchye said leakage in the
distribution system is covered. Commissioner Forssell asked about leakage data, and Ratchye
said we know the difference between purchases and sales, but that some of the difference is
due to mechanical meters operating slowly and not measuring all the gas flow so that the
difference cannot all be attributed to leaks.
Commissioner Schwartz pointed out that the strategic plan says customers should be offered
choices for managing their environmental footprint, but this proposed program does not offer
consumers choices and asked if the strategic objective needs to be changed. Ratchye said that
the supply source is a Council decision similar to the decisions made regarding the composition
of the electric supply portfolio. Commissioner Schwartz disagreed. She said where the
electricity comes from is irrelevant, but if she is being told she can’t have an electric stove, that
is a problem. Ratchye explained again that the proposal is about the gas supply portfolio and
not about electrification.
Commissioner Forssell observed there may be confusion between electrification efforts versus
the proposed carbon neutral gas portfolio.
Commissioner Schwartz asked if we need to change the strategic plan. Interim Director Ed
Shikada said that the strategic plan will be updated.
Commissioner Schwartz said biomethane is not very hard to come by. She said Apple can’t find
biogas to serve its facilities. Dailey replied there is biogas available but very little in California.
She explained that the plan is to get gas elsewhere and displace it in accordance with the
federal renewable fuels rules. She said she has talked to all of the City’s regular gas suppliers
and there is biogas available. She explained the some biogas producers are interested selling a
portion of their production for at a longer term at a fixed price discounted to the spot price in
order to diversifying their sales portfolios.
Commissioner Schwartz said if we are pushing everyone to electrify, we should talk about that
in the future.
Commissioner Ballantine said he likes the flexibility of the proposal that allows more biogas to
be included as it becomes available. Natural gas infrastructure is more resilient than electric
infrastructure. He said that, if and electric outage occurs, it would be a dark day in Palo Alto if
all is electric. He said the proposal is good because it includes biogas at a modest rate increase
while we start to work on initiatives to improve the resilience of the electric grid. He added that
this action helps to support a biogas marketplace and level the playing field for other ways to
get heat, including solar thermal heating. He also noted that energy efficiency and the incentive
to reduce local leaked gas is valued more.
Vice Chair Danaher said he likes the flexibility of the proposal to maximize biogas.
Chair Cook said he likes the staff proposal and appreciates the public comment. He pointed out
Carbon Free Palo Alto’s caution that it will be a distraction from the real goal of electrification
to reduce GHG emissions and might discourage fuel switching. He noted the differences
between the carbon neutral electric portfolio and the proposed carbon neutral gas portfolio
but suggested we test the hypothesis by determining whether the carbon free electricity
dampened the penetration of rooftop solar. He said helping to build a biogas market may lead
to lower prices as has happened with renewable electricity, and this program signals a move
away from the GHG emissions associated with natural gas usage.
Commissioner Schwartz asked if staff has done an analysis of where the electricity comes from
with electric used for heating, positing that additional electric load may cause the use of more
gas to power electric generation. Dailey answered that this proposal has nothing to do with
electric generation or increased electric usage.
Commissioner Ballantine asked if we electrify, would we increase our GHG footprint without
realizing it. Ratchye said that a discussion about electrification will happen at a later date.
