System Capacity Value Meeting
This meeting focuses on how to value DR from an electric
generation resource perspective. The meeting will summarize
the extant methodologies such as the TDV and the CPUC
avoided costs methodologies. Those methods are focused
on the value of measures that can reduce energy usage
over a large number of hours in a typical year. DR,
however, offers its greatest potential value in atypical
years. Therefore methods need to be developed to produce
these atypical values. The meeting will discuss methods
for determining generation values under stress case
scenarios, and defining those scenarios such as low
hydroelectric resources and high natural gas prices.
The meeting will also focus on determining methods for
adjusting the generation shapes currently used in the
TDV and CPUC methods to better reflect the peak value
of energy during capacity constrained periods. Note
that while the focus is on capacity, generation energy
costs and environmental costs will be addressed as well
in this meeting. focused on the technologies that are
applicable to buildings and could provide value as a
demand response (DR) technology. The meeting will explore
the characteristics that make a technology a DR resource
(electric load reduction at the time of system or local
capacity needs, dispatchability does not have to provide
substantial annual energy reductions) as well as the
characteristics that would affect the value of that
technology (predictability of impacts; level of customer
participation needed to attain reductions; persistence
of reductions; limitations on duration, frequency and
cumulative operations; and degradation of reductions
during periods of need). The meeting will also delve
deep into issues related to specification, implementation
costs, production levels, and rollout requirements of
programmable controllable thermostats (PCTs) as well
as similar issues related to other possible DR technologies.
