Purpose and background
Purpose
Conduct a statewide energy efficiency potential study to determine the potential for development of specific natural gas and electric energy efficiency measures in the various regions of New Mexico.
Information will be used by each utility in implementing cost-effective energy efficiency and load management programs under New Mexico’s Efficient Use of Energy Act (EUEA).
Background
EUEA directs New Mexico to support public utility development of all cost-effective energy efficiency and load management measures. These measures include removing regulatory disincentives and allowing rate recovery of energy efficiency and load management program costs. Under PRC rules, IOU gas and electric public utility must obtain PRC approval of energy efficiency programs, implement those programs, and report their results and costs.
No comprehensive statewide study has been conducted to date, although some entities have conducted their own studies.

Objectives
Provide information to the public
Identify energy-efficiency measures that meet the total resource cost (TRC) test
Specify measures relating to housing and building structures and appliances
Address climate zones and other geographic considerations, as well as utility service areas
Describe and quantify the strategies for implementing those measures in a manner that produces the maximum achievable energy savings

Preliminary baseline forecast results for residential and commercial sectors
The following slides present the market characterization, base-year market profiles and baseline forecasts
We also identify key forecast assumptions
Feedback on these assumptions and preliminary results is welcome, but must be provided by April 22
The Global team will reach out to each IOU and the rural coop association by the end of April to finalize

Discussion
Industrial sector analysis
Utilities will provide data by SIC code so we can define the segmentation
We are working with SWEEP to characterize appropriate measures
Sensitivity/scenario analysis
Avoided costs – need to develop a high and low estimates
Appliance/equipment standards – will analyze a scenario with more aggressive standards
Schedule for completion
We will hold several webcasts to review intermediate results in the coming month
Analysis complete by May 15
Final report completed by May 30
