ERCOT Board Defers Decision on Modifying Reserve Margin Target
Copyright 2013 EnergyChoiceMatters.com.
The ERCOT board of directors deferred until September a decision to increase the target reserve margin to 16.1% from the current 13.75%.
ERCOT Board Chair Craven Crowell said that the planning reserve margin, as well as the load carrying capability of wind which is also being reviewed, are directly related to proceedings at the PUCT regarding resource adequacy.
Craven said that action at yesterday's Board meeting on the planning reserve margin would complicate work for such policymakers.
Craven also cited lingering questions from the Texas Industrial Energy Consumers regarding the methodology used by ERCOT's consultant in the loss of load study, including how demand response is counted, whether the forced outage rate is too high for peak periods, and the sensitivity of wind studies.
Craven asked ERCOT Staff to take a second look at the reserve margin recommendation in light of these concerns.
