leverages this framework to deliver on the broad portfolio goals outlined in 1
this eight-year strategic business plan. 2
TSB, defined as “the sum of the benefit that a measure provides to the 3
electric and natural gas systems,”
12
replaces energy savings and peak 4
demand goals beginning in 2024.
13
TSB expresses, in Net Present Value 5
dollars, the lifecycle energy, ancillary services, generation capacity, 6
transmission and distribution capacity, and greenhouse gas (GHG) benefits 7
of EE activities, on an annual basis.
14
TSB ties EE goals directly to the 8
avoided cost value of EE savings, capturing the benefits of saving energy 9
during high value hours of the day and year. It is also fuel agnostic and can 10
facilitate the pursuit of building electrification through fuel substitution. In 11
this application, PG&E explains how it will optimize its portfolio to deliver 12
TSB for California. 13
The second policy change directs PAs to assign programs in their EE 14
portfolios to categories, or “segments,” based on their primary purpose.
15
15
There are three segments: resource acquisition (RA), equity, and market 16
support (MS). Codes and Standards (C&S) programs are considered a 17
separate category. Cost-effectiveness requirements apply to the RA 18
segment
16
while the equity and MS segments must adhere to a budget 19
cap.

Because cost-effectiveness requirements apply only to the RA 20

CPUC TSB Technical Guidance, Version 1.2, October 25, 2021, p. 1. See also p. 7:
“The ACC produces hourly avoided cost values, and the ACC output table for electric
avoided costs instructs the CET whether to use input kW or kWh values, depending
on when the energy is saved. The avoided cost rate is based on price forecasts,
measure impact profiles, climate zones, program administrator, etc. Benefits
associated with avoided kW are only accrued in peak hours, and these benefits flow
into the measure benefits calculation outputted by the CET.”

D.21-05-031, OP 3, p. 81 states,
“Beginning in program year 2022, energy efficiency program administrators who are
investor-owned utilities or community choice aggregators shall ensure that the
forecasted benefits exceed the costs of the resource acquisition segments of their
portfolios, as measured by the Total Resource Cost test, without considering Codes
and Standards programs.”
