Resource Adequacy
Resource adequacy is the ability of electric grid operators to supply enough electricity at the right locations, using current capacity and reserves, to meet demand. It is expressed as the probability of an outage due to insufficient capacity.
Stakeholders will vote on whether it’s worth debating the cost allocation for holders of firm transmission service reservations of more than 1,000 MW.
MISO is considering prohibiting resources on extended outages from participating in capacity auctions or other changes to capture the risk of such outages.
MISO and OMS began distributing their annual joint resource adequacy survey with a new calculation method some stakeholders believe is overly conservative.
CAISO is seeking to create a new transmission access charge area for the Metropolitan Water District of Southern California.
PJM can maintain adequate reliability with a generation fleet almost entirely composed of natural gas units, according to a study the RTO released.
MISO expects a 19.2% planning reserve margin this summer, well above its 15.8% requirement, and a percentage point above its projection last year.
CAISO is preparing for spring oversupply, when unusually high levels of hydro output are expected to compound the impact of growing solar penetration.
General assumptions regarding winter operations will need to be replaced with actual data to improve PJM’s winter resource adequacy analysis.
Load forecast data for the MISO 2017/18 PRA shows that all local resource zones have enough capacity to meet their clearing requirements.
MISO will roll some capacity sitting in the definitive planning phase of its interconnection queue into the annual OMS-MISO resource adequacy survey.
