On page 2 of the Application A vista mentions energy effciency targets established though the
Integrated Resource Plans (IRs). Please provide a copy of the IRs used to establish the
effciency targets for both electrc and gas. If Avista used additional analysis, or relied upon
additional resources to establish these targets, please provide these also.
RESPONSE:
The IRs used to establish the efficiency targets for both electric and natual gas are the 2009 IRs.
Please access these through the lin provided below for both the electrc and natual gas IRs.
Electrc targets are found on page 3-10 withn the electrc IR. This is a system taget and Idaho's
portion was allocated on a customer basis. Natual gas targets are found on page 4.9 of the natual
gas IR. Again, the "nort division" target is a system target for the combined Idaho-Washington
serce terrtory. Idaho's portion of the target is derved using number of customers.

REQUEST:
Please provide the most recent study or other document that quantifies the DSM potential for both
gas and electrc applicable to Avista's Idao servce tertory.
RESPONSE:
The most recent study quantifyng the DSM potential for electrc is the Conservation Potential
Assessment (CPA) completed in 2011 using a 2009 base year since the study began in 2010.
Please refer to the attachments for the CPA and the Appendices.
For natual gas, the most recent document quantifyng the DSM potential is included within the
natual gas IR. Please refer to Appendix 4.1.1. In addition, Global Energy Parers, the same
consultant that prepared the attched electrc CPA is beginnng our natual gas CP A that wil
. accompany the upcoming 2012 Natual Gas IR.

The Application states, on page 2, Avista achieved 105% of the IR goal for electrcity, but only
85% of the IR goal for natual gas. Please explain why this record of achievement support a
larger reduction in the gas rider tarff than the electrc rider tarff.
RESPONSE:
The increase in Idaho Schedule 191, effective October 1, 2010, was to cover the operations of
Idaho natural gas energy efficiency programs as well as to reduce the underfded balance of over
$1.3 milion (balance at effective date). To date, we have a overfuded balance of $1.1 milion for
Idaho natual gas so the proposed reduction is to reduce the overfded balance but should leave
enough fuding to cover operations even with increasing natual gas tagets.

REQUEST:
The Application states on page 3:
"Avista has long encouraged the direct-use of natual gas by its electrc customers.
As an electrc effciency program, the Company is continuing this effort with
residential rebates for the conversion of electrc and natual gas space and water
heat loads, as well as a broad program for any non-residential electrc to natual gas
conversions meeting specific crtera for relative British Thermal Unit (BTU
effciency. The cost-effective potential for these measures has been incorporated
into Avista's Integrated Resource Planing effort and are contained within the
identified acquisition goal."
For electrc to natual gas conversions please explai:
a. Whch IR, electrc or gas, the company uses to establish the cost effective potential and
acquisition targets for these programs.
b. Whch tarff rider, electrc or gas, provides the fuds for these programs.
RESPONSE:
a. The Company uses the electrc IR to establish cost-effective potential for fuel
conversions and electrc effciency upgrades. The Company uses the natual gas IR to
establish cost-effective potential for natual gas upgrades.
b. The electrc tarff rider fuds fuel conversions (electrc to natual gas) and electrc
effciency upgrades. The natual gas taff rider funds natual gas effciency upgrades.

The Application states on page 6: "For 2010, the Company's portfolios were cost-effective with
TRC and PAC ratios of 2.33 and 5.02, respectively for its electrc portfolio and 1.62 and 3.60,
respectively for its natual gas portfolio." Please provide:
a. The documentation supporting these calculations.
b. The results of any cost effectiveness tests at the program level for both gas and electrc.
RESPONSE:
a. Please refer to the Company's DSM Anual Report, ICL_PR_005 Attachment A, for
additional documentation supporting these calculations, specifically Tables 1, 2, 5 and 6 as
well as the Appendix page 30 for additional detail by state.
b. Please refer to the Company's DSM Anual Report Tables 15 and 16 for cost-effectiveness
at the program level for both electrc and natual gas with net-to-gross factors applied.
