AS REQUIRED BY THE ENERGY POLICY ACT OF 2005, A
PUBLIC HEAI~NG TO CONSIDER A RECOMMENDATION TO
NOT IMPLEMENT THE ELECTRIC TIME-BASED METERING
AND PRICING OPTIONS
RECOMMENDATION
In order to meet the reporting requirements of the Energy Policy Act of 2005 (EPACT), staff
recommends that the CiD’ Council hold a public hearing and find that it is not appropriate to
implement the electric time-based metering and pricing options required by the EPACT, and
direct staff to evaluate the future teclmical feasibility, customer interest, and cost-effectiveness of
providing time-based rate options to each customer class and report back to Council by June 30,
2009.
BACKGROUND
To meet the EPACT requirements, the City of Palo Alto Utilities (CPAU) must offer time-based
metering and pricing options to all customer classes by August 2007, or issue a decision as to the
appropriateness of implementing the standards. This report addresses those requirements.
Time-based metering and pricing options provide incentives for customers to respond to electric
supply costs and constraints. Modifying behavior in response to time-based prices can result in
lower costs, reduced enviromnemal impacts and increased system reliability. Electric supply is
more costly during periods of high usage, and therefore, reduced use or shifting use to less costly
time periods can reduce utility costs and save money for customers. Because high-price periods
coincide with lower power generation efficiency and greater transmission system congestion,
time-based pricing also realizes enviromaaental and reliability benefits.
The specified time-based rate options to be considered under EPACT are: 1) time-of-use pricing;
2) critical-peak pricing; 3) real-time pricing; mad!or 4) peak load reduction credits.
t)Time-of-use (TOU) pricing provides an electric rate to customers based upon the time of day,
or for pre-determined blocks of hours during the day, that electric energy is consumed. TOU
rates are usually seasonal in nature, apply to pre-determined blocks of hours, and are
CMR:299:07 Page 1 of 3
published in advance. Presently, TOU rates in Palo Alto are offered only to large conm~ercial
customers on a voluntary basis.
Critical-peak pricing (CPP) goes a step ful~her than TOU pricing by adjusting prices more
frequently and with shorter notice, with an increase of prices for peak usage hours during
days of unusually high electric system demand to directly reflect actual wholesale market
price spikes.
Real-time pricing (RTP) retail rates change on an hourly, or possibly more Kequent, basis.
Rates are usually announced to customers on a~ advanced, or fox, yard, basis.
Peak load reduction credits (PLRC} are provided to large load customers who enter into pre-
established a~eements to reduce load during peak hours.
At the current time, CPAU offers TOU rates to commercial and industrial customers (rates E-4-
TOU and E-7-TOU). Also, CPAU’s existing volunta’y toad curtaihnent prodam has
successfully demonstrated demand reduction results that help to ensure reliable system operation
and minimal overhead cost.
DISCUSSION
TMough prior studies and economic evaluations, staff has determined that implementation of
time-based metering and-pricing options are not cunently practical or effective for some Palo
Alto electric customer classes, and it is therefore not appropriate to implement the EPACT time-
based metering standards for all customer classes at this time. This is due primarily to utility
billing system limitations, insufficient metering capability, and uncertain and expected low
customer participation at current time-based cost differences.
Limitario~zs of the current customer it~formatio~ and billing s)’s~ems.
The cmrent Utilities billing system camot readily accept the necessary pro~amming
modifications required to generate customer bills on a TOU rate option. Manual billing
would be required to implement these rate options, and the cm-rent staffing level is
insufficient to support manual billing. The CPP, RTP and PLRC time-based rate options
are not available under the cunent billing system either. The cunent billing system
version is no longer being supported by the software vendor, which has resulted in the
business decision to migrate to a new Utility Customer Information System in
conjunction with the city-wide SAP upgade.
b~suffcien~ meteri~g capabilio’.
The only Palo Alto meters capable of time-based pricing are demand meters currently
installed in convnercial and industrial applications. The majority of cunent meter
installations are not capable of being pro~ammed for TOU, CPP or RTP options. A new
policy would need to be established to replace existing residential and commercial single-
phase electric meters with meters capable of recording consumption by time. Staff’s
review of options for residential and commercial metering for the FY 2008/09 will
include meter purchasing, calibration standards, communication capabilities, meter
maintenance budgets, staffing, and Capital Improvement Program impacts.

U~certai~ a~d low customer garticigatio~z.
Palo Alto has offered voluntary TOU rates to commercial demand-metered electric
customers since 3anuary 2002, but has not had any customers choose service under the
commercial TOU rate schedules. Furthermore, consultant studies to evaluate the
customer potential for a demand response prodam, whereby customers receive financial
incentives to reduce demand during high demand on-peak hours based on the Ufility’s
avoided cost, have determined that such pro~ams require ~eater differences between on-
peak and off-peak prices than is currently available to attract significant customer
participation. Low participation may require charging pa-ticipating customers for their
time-based meter (common to other electric utilities), which would make the program
even less attractive.
For these reasons, staff has determined that it is not appropriate to implement the electric time-
based metering and pricing options required by the EPACT at the current time.
RESOURCE IMPACT
The costs associated with the recommended evaluations will be included in the various Utilities
Department operating budgets.
POLICY IMPLICATIONS
These recommendations do not represent a change in current City policies.
ENVIRONMENTAL REVIEW
The adoption of the resolution does not constitute a project under the California Environmental
Quality Act. Therefore, no enviromnental assessment is required.

~ ~ the ~ " ~’request, a time-based rate schedule under vh~cn rate c~argca
by the electric utility v" -’~ ’ " ~a~ ourm~ different time periods and
reflects the vaqance, if any, in the utility’s costs o£ generating
and purchasing electcic~ty at the wholesale level. The time-based
rate ~chemfle shall enable the electric consumer to manage
energy use and cost through advm~ced metering and
communications tec!~ology.
(B) The t}:?es of time-based rate schedules that may be offered
under the schedrde referred to in subparagaph (A) include.
among others--
(i) time-oLuse pricing whereby electrici"U p~fices are set
for a specific time period on an advance or for~vard basis,
t3?ically not changing more often tha~ twice a year,
based on the utility’s cost of generating and/or
purchasing such elecU@ity at the wholesaie level for the
benefit of the consumer. Prices paid for energy
consumed during these periods sha!l be pre-established
:~d known to consumers in advance of such
consumption, allowing them to vary their demand and
usage in response to sud~ prices and manage their energy
costs by shifting usage to a lower cost period or reducing
their consumption overall;
(ii) critical peal< pricing a,:hereby time-of-use prices are
in effect except for certain peak days, when prices may
reflect the costs of generating an@’or purchasing
electricity at the wholesale tevel and when consumers
may receive additional discounts for reducing peak
period energy consumption;
(iii) real-time pricing whereby electricity prices are set
for a specific time period on an advanced or forward
basis, reflecting the utility’s cost of generating and/or
purchasing electricity at the wholesale level, and may
change as often as hourly; and

(iv) credits for consumers with large loads who enter into
pre-established peal{ load reduction agreements that
reduce a utility’s planned capacity obligations.
(C) Each electric utility subject to subparagraph (A) s!~all
provide each cusiomer requesting a time-based rate with a time-
based meter capable of enabling the ulilily and c~tstomer to o~er
and receive such rate, respectively.
(D) For purposes of implementing ttais paragraph, any reference
contained in this section to the date of enactment of~he Public
Utility Regulatory Policies Act of t 97.8 shall be deemed to be a
