ERCOT says it is prepared for a polar blast that is expected to bring sub-freezing temperatures to Texas this weekend.

The ISO's latest seasonal assessment shows it has more than 87 GW on hand to meet a forecast peak demand of 67.4 GW this winter.

Gas supply to Eastern New York could be limited during freezing weather because demand may exceed interstate pipeline capacity, NYISO’ stakeholders were told.

MISO expects to easily navigate normal winter conditions with its firm supply but said a worst-case winter storm in January could exhaust emergency reserves.

December contained unexceptional load and growing energy prices, according to MISO's monthly operations report.

MISO flirted with its first maximum generation event of the year, a month after it cautioned members that winter operations would get risky.

MISO raised alarm bells about soaring forced outages should a severe arctic blast descend on the footprint this winter.

ISO-NE stakeholders approved tariff changes that incorporate a new transmission planning process focused beyond the RTO’s current 10-year planning horizon.

Twitter users were quick to pounce on ERCOT's quiet release of its winter resource assessment and the resignation of a new board member.

NYISO on Tuesday reported sufficient capacity this winter to meet forecasted peak demand conditions, with a total of 42,415 MW of resources available.
