Public Utility District
CONSENT
To: Board of Directors
From: Steven Poncelet
Date: February 17, 2010
Subject: Consideration of Adopting Energy Efficiency Targets to meet the SB
1037/AB 2021 Requirement
1. WHY THIS MATTER IS BEFORE THE BOARD
SB 1037/AB 2021 requires publicly-owned utilities (POUs) to invest in all cost-effective,
reliable and feasible energy efficiency as the first source of power in their energy portfolio.
Setting energy efficiency targets requires Board approval.
2. HISTORY
SB 1037 requires publicly-owned utilities (POUs) to invest in all cost-effective, reliable
and feasible energy efficiency as the first source of power in their energy portfolio.
California Assembly Bill 2021 restated that requirement and adds additional
independent reporting requirements for POUs to "identify all potentially achievable cost-
effective electricity efficiency savings and shall establish annual targets for energy
efficiency savings and demand reduction for the next 10-year period'. The Board
adopted the first set of energy efficiency targets in 2007 and established a target of
10,014 MWh. This target equated to an average of-0.67% of total load per year. The
District, as well as all participating California POU's, must formally adopt their energy
efficiency targets on a triennial basis.
3. NEW INFORMATION
The District and the Northern California Power Agency (NCPA) are in the process of
updating energy efficiency targets through a member-wide study conducted by Summit
Blue Consulting. Before the Board is the first. triennial update using input from the
Summit Blue Consulting model and with adjustments made by District staff in
collaboration with NCPA staff.
An excerpt of the energy efficiency potential study results, recommended by staff, is in
Attachment 1. A summation of the 10-year results is:
Energy Savings: 19,880 MWh (from 2011 through 2020, -1.1% MWh sold/year)
Demand Savings: 2.573 MW (from 2011 through 2020, -0.7% per year)
These targets are based on the District's documented energy saving results for the past
two years but also acknowledges that, over a 10-year period, maintaining the District's
energy savings AND cost-effectiveness will become increasingly difficult as the District
moves past the 'low hanging fruit' and we start to saturate some programs. This trend
of declining energy savings and increasing program costs over times has been well
documented in California's electric utilities. The1.1% per year target over 10 years,
however, represents significant electric savings and puts the District near the top of
California utilities for setting energy savings targets.
4. FISCAL IMPACT
The costs for the District's energy conservation programs are included in the approved
FY10 & 11 budgets and are projected for future years. There is no direct fiscal impact
associated with this action item.
5. RECOMMENDATION
Adopt Truckee Donner Public Utility District's energy efficiency targets for the period
2011 through 2020 as follows:
Energy Savings: 19,880 MWh
Demand Savings: 2.573 MW
