SUBJECT: Final 2020 Annual Savings Report

NEEA is an alliance of utilities that pools resources and shares risks to transform markets toward
energy efficiency that benefits consumers in the Northwest. NEEA’s role is to establish technology
and market conditions that advance energy efficiency in markets in a sustainable way.

Energy savings are enabled by the alliance’s market transformation programs, codes and
standards work, and investment in tools, training, resources, data and research to support greater
efficiency. The programs seek to affect sustainable changes in markets, which then result in energy
savings.

As such, Idaho Power has asked NEEA to report savings based on an established agreement.
Based on that agreement, NEEA provides annual tracking and reporting of savings resulting from
long-term market transformation efforts.

This memo provides the final energy savings estimates for 2020. NEEA allocates the savings based
on Idaho Power’s funding share of its regional investment. The savings are above NEEA’s market
transformation baseline and are net of savings claimed through regional utility programs. Details
about baseline and technical assumptions are in the attached Excel spreadsheet.

Please do not hesitate to contact Christina Steinhoff at 503.688.5427 with any questions about this
report.

Final 2020 Savings Estimate Summary
NEEA estimates Idaho Power’s 2020 annual electric energy savings associated with its initiatives is
2.01 aMW (Table 1). These savings are above the NEEA baseline1 and exclude an estimate of
savings that Energy Trust of Oregon, Bonneville and local utilities claim through locally run
programs. NEEA allocates energy savings based on funder share.

Residential 0.98
Commercial 0.77
Industrial 0.26
Notes:
The values might not add up because of rounding.
These are site-based, first year electric savings.
Net Market Effects= Total Regional Savings- Local Program Savings -Baseline Savings
2020 Updates to Voluntary Program Savings
Approximately, 0.50 aMW come from voluntary programs like Heat Pump Heaters, Retail Products
Portfolio and residential new construction. NEEA also added savings from its Extend Motors
Products Program. The remining savings come from codes and standards either tied to voluntary
programs or related to direct codes and standards work.
The voluntary program savings is greater than the 0.33 aMW NEEA reported in February 2021
primary because:
•Extended Motors Products: NEEA added the Extend Motors Products program to its savings
portfolio. NEEA partnered with the League of Pacific Northwest to increase the region’s
motor fleet efficiency by influencing end-users to improve motor management services.
Idaho Power’s funding share of the savings increased by 0.02 aMW from the Q1 forecast.
•New Construction: NEEA was able to track significantly more certified above code homes
within the region. The number of certified homes increased from 7,249 in the forecast to
9,165, resulting in 0.09 more aMW of savings for Idaho Power.
•Commissioning: NEEA had a conservative forecast of commissioning. NEEA updated the
forecast based on its annual commissioning survey and new construction data from Dodge.
Idaho Power’s funding share of the savings increased by 0.03 aMW from the Q1 forecast.
1 NEEA estimates Baseline as the savings that would have occurred without NEEA, utility, the Bonneville Power
Administration, and the Energy Trust of Oregon’s market intervention.

spreadsheet.2
Value of Codes & Standards
The remaining savings come from codes and standards work. This work can both be tied to a
program (e.g. Next Step Homes, Clothes Washers and Heat Pump Water Heaters) or not.
Influencing the adoption of codes and standards is a key market transformation strategy, and,
when successful, results in a sustained market change. On behalf of the region, NEEA works at
state and national levels to influence the adoption of increasingly stringent building energy codes
and federal appliance and equipment standards. Working in collaboration with its partners, NEEA
gives the Northwest a voice in codes and standards processes and is frequently the only efficiency
organization directly representing utilities in these forums.
Value of Future Portfolio
NEEA has several programs such as Commercial Window Attachments, Very High Efficiency
Dedicated Outdoor Air Systems, and Variable Capacity Heat Pumps that are new and do not yet
have associated savings rates. In the next few years, NEEA anticipates these voluntary programs
will begin delivering savings. NEEA is also investigating several emerging technologies with savings
opportunities for the 5-10-year horizon. These include thin triple-pane windows and ultra-high-
definition televisions.
Historical Updates
NEEA updates its historical savings estimates based on new data. Changes to the 2019 savings
estimate were not significant. More details about the historical updates are available in the 2019
Updates tab of the attached spreadsheet.

2 Note that NEEA is basing the 2020 DHP savings estimate on 2019 data and 2020 local programs data. NEEA will
update these estimates in September with final data from manufacturers.

Appendix A: Methodology to Forecast Savings
Allocation Methodology
NEEA allocates regional savings (Idaho, Montana, Oregon, and Washington) using shares of
investment by funder. These shares vary by funding cycle. Savings from previous investments
receive the previous funder share. Savings from current investments receive the current funder
share. Table 2 shows the funder shares.
Table 2: Funder Shares
Business Plan Funding Share
2020-2024 9.23%
2015-2019 8.01%
2010-2014 8.67%
Prior 6.42%
Baseline and Technical Assumptions
This report follows NEEA’s method of measuring electric energy savings from market
transformation efforts. The baseline is an estimate of the market adoption without intervention
by NEEA, the Bonneville Power Administration, the Energy Trust of Oregon and utilities. Prior to
reporting the savings above the baseline, NEEA removes the savings counted through the local
programs. This effort avoids double counting energy savings.

The technical assumptions come from third-party research including NEEA-contracted research
and the Regional Technical Forum.
