NERC and WECC warned that inverter-based resource performance remains an ongoing issue in the Western Interconnection.

NERC found that the bulk power system was generally reliable and resilient in 2022, but forced outages among coal and natural gas plants hit their highest level in the decade.

A whitepaper on a pressing matter — managing battery systems connected to the grid — bogged down in a debate over its details as NERC’s Reliability and Security Technical Committee met Wednesday.

Most regions of the North American grid remain at elevated risk of supply shortfalls this summer, NERC said in its 2023 Summer Reliability Assessment.

FERC approves NERC’s inverter-based resources plan, proposed in February, and declines to include industry suggestions.

The N.Y. State Reliability Council Executive Committee indicated its Installed Capacity Subcommittee may increase the amount of 10-minute reserve assumptions.

The Department of Energy says it will fund eight projects to demonstrate how solar, wind, storage and other clean energy resources can support the grid.

NYISO updated the Operating Committee about forecasted summer conditions, assessing that margins are declining over time as NYISO transitions to clean energy.

NERC CEO Jim Robb said he felt “sobered by the amount of work in front of us” but confident the ERO can address the grid’s “hyper complex risk environment.”

The New York State Reliability Council has approved a uniform set of requirements for inverter-based resources over 20 MW to connect to the NYISO grid.
