Energy Efficiency Evaluation, Measurement, and Verification

2018-2020 Energy Efficiency Evaluation Overview

2018-2020 EE Portfolio Report to the Governor and Legislature, June 2022

Below is a chart that compares first year savings goals to evaluated first year savings across the energy efficiency portfolio for the years 2018 through 2020 (data from the 2018-2020 EE Portfolio Report to the Governor and Legislature, linked above). The drop-down menu at the top of the chart can be used to change the savings metric that the chart shows. At the bottom of the chart, there is a link to a full Tableau dashboard with more data from the 2018-2020 EE Portfolio Report to the Governor and Legislature.

2018-2020 Evaluation Plan

Energy Division and the IOUs collaborated on an Evaluation Plan for energy efficiency programs that comprise the 2018-2020 program cycle. The evaluation plan includes specific sector approaches, including market, process, and impact evaluations, as well as proposed budgets. This Plan update reflects prioritization of studies and allocation of funds for EM&V in D.14-10-046. Read the Evaluation Plan here.

Background and Historical information  

  • Program Funding - Program-specific funding and projected energy savings for the utilities' 2010-2012 energy efficiency portfolios.
  • Program Reports - Monthly, quarterly and annual utility program reports, including reported energy savings and expenditures, for the 2010-2012 and prior program cycles.
  • Program Performance Metrics (PPMs) and Market Transformation Indicators (MTIs) - Resolution E4385 established PPMs and MTIs developed by Energy Division in collaboration with the utilities for the Statewide Programs of the 2010-2012 program cycle. The Complete PPM Worksheets referenced in the resolution provides a comprehensive framework of PPMs, MTIs, and associated objectives.
  • Policy and Planning (PPD) and Energy Division (ED) workshop series on 2013-2015 Energy Efficiency EM&V - D.10-10-033 - directed PPD and ED to hold a series of workshops focused on EM&V issues related to the 2013-2015 Energy. Four workshops, each focused on a specific issue, were held through summer 2012:
    • Experimental Design - materials available here.
    • Market Transformation Metrics - materials available here.
    • Load Forecasting
    • Macro-consumption metrics  
  • Energy Efficiency Financing Workshop - Pursuant to an ALJ Ruling, an EE Finance workshop was held February 8-10, 2012. EE Finance Workshop materials and presentations:
