Due to A vista system capacity issues and seasonal spot power prices, air conditioning
load will be given priority in customer selection. However, the Company intends to explore the
effects of demand responses on both winter and summer peaks. Therefore, customers with
HV AC systems (for heating and air conditioning) will be given equal priority. Additionally, in
order to gain knowledge and experience with a variety of demand response technologies, the
Company will install demand response equipment in the above listed applications.
Measurement & evaluation (M&E) is integral to defining benefits of a pilot program and
identifying areas for improvement or modification. A vista s M&E will examine four
components: (1) kilowatt savings, (2) technology, (3) customer acceptance, and (4) an
evaluation of reductions in peak demand on the Company s distribution system.
A vista requests that the Commission approve the proposed Schedule 96 tariff and related
tariff changes for an effective date ofJuly 15, 2007.
ST AFF REVIEW
Staff has reviewed A vista s proposal and discussed elements of the pilot program design
and M&E intentions with Company staff. Staff appreciates the opportunity to participate in
development of the demand response pilot program prior to the Company s filing.
Staff believes the potential benefits of demand response efforts merit A vista s attention
and finds the proposed pilot to be an appropriate means of exploring demand response issues.
As indicated in the Application, this will essentially be A vista s first effort in the demand
response area, and the Company has had the luxury of being able to review the efforts of other
utilities in designing these initial steps. The proposed pilot effort is limited in scope, yet is
designed to obtain considerable information for a relatively modest investment. The proposed
pilot appears to have been designed to minimize the duplication of efforts previously conducted
by other utilities, and focuses on verifying the results of other utility programs and their
applicability to Avista s service area and system, and to examine new issues and technology.
The Application identifies a broad range of objectives for the measurement and evaluation of this
pilot program. In addition to measuring peak kW reductions, Staff encourages the Company to
measure kWh as well to examine whether energy use is reduced or shifted to other times.
On June 21 2007, Avista filed additional comments, clarifying that as a pilot program
the program includes flexibility to allow for modifications based upon market conditions and
lor findings." The comments include the example of expanding the program beyond the two
