ERCOT is repeating many of the preparations it took before last summer as it looks ahead to even tighter reserve margins in 2019.

NYISO said it will have adequate capacity on hand to meet its forecasted peak demand of 24,260 MW for the 2018/19 winter season.

Several MISO stakeholders are criticizing Tariff filings the RTO plans to make by the end of the year to free up an additional 5 to 10 GW of capacity.

ISO-NE’s interim proposal to use an out-of-market mechanism to address concerns about fuel security was approved by FERC.

Stakeholders are skeptical of MISO's proposed Tariff revisions imposing stricter outage rules and load-modifying resource requirements.

ERCOT’s Technical Advisory Committee endorsed a staff suggestion to increase by 50% the boundary thresholds used to project future loads in Far West Texas.

ISO-NE said it expects to have sufficient capacity on hand this winter to meet load, which it forecasts will peak at 20,357 MW in normal conditions.

The National Energy Technology Laboratory accused PJM of providing misleading analysis of its resource availability during last winter’s “bomb cyclone.”

ISO-NE kicked off its formal annual review of the transmission system to delineate zones for Forward Capacity Auction 14.

MISO staff now say they will zero in on three short-term resource availability and need fixes that can be rolled out early next year.
