CONSERVATION POTENTIAL
ASSESSMENT (CPA)
The Conservation Potential Assessment (CPA) developed by Lighthouse Energy Consulting for Inland Power & Light is an analysis of energy data and findings. The CPA estimated the cost-effective energy savings potential for the period of 2024 to 2043. This report describes the results of the full 20-year period, with additional detail on the two-and 10-year periods that are the focus of Washington's Energy Independence Act. (EIA). The initial two years of this study are also the final two years of the four-year period covered by Inland Power's first Clean Energy Implementation Plan (CEIP). If desired, the results of this study can be used to update the conservation target identified in that CEIP.
​
Inland Power provides electricity service to over 36,000 customers across 13 counties in eastern Washington and northern Idaho. The EIA requires that utilities with more than 25,000 customers identify and acquire all cost-effective energy efficiency resources and meet targets set every two years through a CPA. Inland Power's history of consistently exceeding its biennium conservation targets is show in Figure 1 below, which is based on EIA compliance data reported to Washington's Department of Commerce.
The EIA specifies the requirements for setting conservation targets in RCW 19.285.040 and WAC 194-37-070 Section (5), parts (a) through (d). The methodology used in this assessment complies with these requirements and is consistent with the methodology used by the Northwest Power and Conservation Council (Council) in the 2021 Power Plan. Washington's Clean Energy Transformation Act (CETA) has additional requirements for CPAs; namely, that the assessment of cost-effectiveness make use of specific values for the social cost of carbon. Appendix III details these requirements and how this assessment fulfills those requirements.
Your Comments
The purpose of this report is to consider and take comments on the establishment of Inland Power's ten-year conservation assessment and two-year conservation targets. This is based on the energy efficiency requirements put forth in the Energy Independence Act (I-937) of 2006.
