New England regulators agreed that their region faces a growing winter reliability challenge but expressed skepticism over ISO-NE’s proposed solutions.

Midwest gas-fired generators have made incremental improvements to ensure fuel supply over the past year, MISO stakeholders learned.

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.

A NERC report finds that the grid’s dependence on gas-fired generation will require pipeline outages to factor more heavily into reliability planning.

At the NYISO Management Committee, the RTO said that it declared a major emergency on May 21 after the loss of 1,000 MW of generation in ISO-NE.

FERC rejected Dominion Resources’ request to recover almost $400,000 in uncompensated costs incurred when it ran four dual-fuel units on fuel oil.
