MISO is questioning whether its one-day-in-10-years loss of load standard remains the best method for establishing resource adequacy, and state regulators want in on potential decisions.

Assembly Bill 2368 would require the California Public Utilities Commission to adopt a 1-in-10 loss of load expectation — or a similarly robust planning standard — when setting resource adequacy requirements.

NYISO's update to its draft Reliability Needs Assessment still shows an expected capacity shortfall by 2034, though it is slightly less than what was initially presented in July.

SPP directors and regulators have approved the grid operator’s first winter planning reserve margin, endorsing a base PRM that is 3 percentage points higher than many of its utilities wanted.

New York will be short 1 GW of resources by 2034, driven by increased demand, large load growth and lack of natural gas, according to the preliminary results of NYISO's biennial Reliability Needs Assessment.

FERC said it needs more explanation behind MISO’s plan to use a capacity accreditation that would accredit resources based on a combination of their projected availability and historical performance during periods of high system risk.

A new report from NERC and the National Academy of Engineering explored the shortcomings of traditional resource adequacy metrics and alternatives under development.

FERC found SPP’s tariff revisions laying out how it determines its planning reserve margin methodology only partly met the commission’s order on rehearing and directed an additional compliance filing.

ISO-NE outlined its current thinking on a potential Regional Energy Shortfall Threshold at the NEPOOL Reliability Committee.

Three years after a deadly winter storm nearly imploded the ERCOT grid, stakeholders in the Texas market are working on a reliability standard that may be stricter than industry norms.
