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.
FERC and grid operators will explore "resilience" following the commission’s rejection of Energy Secretary Rick Perry’s proposed rulemaking.
CAISO
California faces a “severe shortage” of transmission capacity needed to tap potential New Mexico and Wyoming wind resources, CAISO said.
While the high load and generation outages followed the pattern of the polar vortex, MISO managed to keep prices stable and maintain better reliability.
MISO’s next capacity auction will likely rely on megawatt values and limits similar to those underpinning last year’s auction.
PJM
Grid operators turned to coal- and oil-fired generation as Arctic air sent temperatures plunging to record lows from the Great Plains to the Deep South.
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.
