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.
CAISO
The California PUC (CPUC) will vote on a proposal to replace reliability-must-run contracts between CAISO and Calpine.
The three grid operators serving the East Coast, ISO-NE, NYISO and PJM Interconnection, have so far weathered the extended cold snap gripping the region.
The new year’s frigid temperatures resulted in a new winter peak demand for ERCOT Wednesday morning.
ERCOT
The ERCOT year-end Capacity, Demand and Reserves (CDR) report projects a 9.3% planning reserve margin for 2018.
MISO said it will defer any initiative to account for outages in capacity planning until it kicks off a broader discussion on overall resource availability.
NYISO
Generation coming online in the next few years will be enough to maintain reliability after the Indian Point nuclear plant shuts down, NYISO said.
MISO will pre-emptively refile its current resource adequacy construct for FERC approval Friday.
NERC
NERC released its annual Long-Term Reliability Assessment, urging preservation of “essential reliability services.”
ERCOT
ERCOT’s summer peak demand is expected to reach 85.01 GW by 2027, a 22.36% increase over this summer’s peak.
MISO’s Zone 4 either has sufficient reserves or is in dire straits, depending on the viewpoint expressed at an Illinois Commerce Commission workshop.
