City Manager’s Report
HONORABLE CITY COUNCIL
FROM:CITY MANAGER DEPARTMENT: ADMINISTRATIVE
SERVICES
DATE:JANUARY 20, 2004 CMR: 116:04
SUBJECT:CITY OF PALO ALTO’S ENERGY TRANSACTION
ACTIVITY REPORT FOR THE FIRST QUARTER, FISCAL
YEAR 2002-03
This is an information report and no action is required.
BACKGROUND
The purpose of this report is to inform the City Council of the status of the City’s energy
portfolio as of the end of the first quarter of fiscal year 2003-04. The City’s risk
management policies require that staff report to Council on the City’s energy portfolio
composition compared to Council-adopted policy, portfolio performance, and other key
market information.
DISCUSSION
Open Transactions as of September 30, 2003
Open transactions are commitments which the City has made to
electricity or gas, but for which supplies have not been delivered.
purchase either
Electricity." The City’s current transactions in electricity are with Western Area Power
Administration, which provides 100% of current load, and Northern California Power
Administration, which provides "within month" balancing. The City currently holds one
long-term position in the energy market with non-governmental organizations. This is a
Quarter 1 and Quarter 4 purchase for calendar years 2005 through 2009. The delivery of
the commodity is 25 MW for 24 hours per day, seven days a week. The City purchased
this commodity for $20.0 million. The current market value of this transaction is $26.7
million. The Mark to Market (MTM) value, the difference between the original purchase
price and the current value of the contract, is $6.7 million, representing an increase of 33
percent. A positive MTM indicates that the contract (or portfolio) is currently worth
more now than when it was purchased, based on the current forward price curve. It is
important to note, however, that the MTM represents a snapshot only, and changes on a

daily or even hourly basis. One would expect that, given the City’s laddering purchasing
strategy, the MTM value will tend to be relatively stable and closely track the market.
This means that the purchases will, on average, largely mirror the marketplace. The
market valuation is based on data provided by NYMEX and BP North America.
The electric portfolio is approximately 9% in surplus in the coming year, assuming
average hydro conditions. Considerable deficits exist from January 2005 and beyond and
staff is working to fill future requirements. Completion of the Gas and Electric Master
Agreements, and their approval by Council last quarter (CMR:482:03 and CMR:510:03)
will provide the authority and contract terms and conditions for staff to execute block
purchases approved by Council (CMR:288:03) and bring the portfolio within appropriate
bounds set by expected load. Master Agreements represent contracts that qualify
suppliers to serve as eligible counter party suppliers for the City.
Electric supply portfolio net costs for FY 03-04 are presently estimated to be
approximately $10 million below budgeted levels. This is a result of commodity purchase
credits from the Western Area Power Administration (WAPA). The June 30, 2004 supply
reserve balances are projected to be $6.3 million above the $54 million maximum reserve
target. These projections do not provide for considerable regulatory/legal uncertainties.
Gas: The current gas portfolio consists of 44 open transactions (transactions for which
gas has yet to be delivered). The contract volume of these transactions is 5,882,485
MMBtu with total commitments of $25.6 million. The current MTM value of these
transactions is $557,000. The average transaction duration is approximately 3.7 months
with transactions ranging in duration from 1 to 24 months. The counterparties for the
open transactions include BP North America and Sempra Inc.
The figure below shows the historic MTM value for the gas portfolio since January 2002.

Date
The laddered purchasing strategy continues to be implemented, with 89% of gas required
to meet pool loads in FY 03-04 purchased already. The weighted average cost of gas for
Palo Alto pool customers is currently below market prices.
Total supply portfolio costs are up by $1.5 million from budgeted numbers, though a
corresponding revenue increase from G3 customers largely offsets these higher costs.
The gas supply rate stabilization reserve balances are projected to be approximately $8
million at the end of June 2004. The Council approved reserve minimum maximum
range is $6-12 million.
Value at Risk
The "riskiness" of an energy portfolio that changes over time can be measured in many
different ways. The industry standard is to use a ~value at risk" (or VaR) measure as a
key indicator. The VaR measures the risk that adverse market conditions will force
CPAU to use reserves to cover costs over what is charged to ratepayers on purchases not
yet made to meet load. In using VaR, the focus is made solely on negative or adverse
changes that could impact ratepayers. In this report, the VaR measures the amount of
money required from reserves due to adverse market changes occurring within a one
week period. In addition, the VaR assumes that the "worst" outcome occurs only one in
20 times (95%) over the next 12 months.
CMR: 116:04 Page 3 of 6
In compliance with the Risk Management Guidelines, the Utilities’ Front Office and the
Energy Risk Manager monitor the VaR and ensure that its value is limited to below 10%
of the existing supply reserve levels for both electricity and gas. Currently, the VaR for
the electricity portfolio is 1.8% and that for the gas portfolio is 2.1%. The historic levels
of both these values are presented in the following graphs, along with the values of the
reserve levels.

Credit Risk
Electricity: Currently, the City purchases electricity from the Western Area Power
Administration (WAPA) for most of its load. WAPA is a Federal Agency and operates
under the full faith and credit of the United States Government, minimizing the City’s
credit risk. The City does have one transaction with an A- rated counterparty. The
current credit exposure is $6.5 million for a contract for delivery between 2005 and 2009.
It should be noted that post 2004 credit risk is likely to increase as the City increases its
transactions with non-governmental counterparties which have a lower credit rating than
the Federal Government. All counterparties on the proposed supplier list are highly
creditworthy and will be carefully monitored as part of risk management program.
Gas." Details on the City’s credit exposure are presented in the following table. The City
has exposure to two counterparties. The first counterparty is rated AA+, and currently
this party has a credit exposure to the City of approximately $543,000. The second
counterparty is rated BBB+ and the City’s credit exposure is $1.1 million. Thus, the
C]V[E: 116:04 Page 5 of 6
City’s total credit exposure is $557,000. In both cases the City’s credit exposure is ,,veil
within the limits established by the Risk Management Policy and Guidelines.
