MISO said its second, mostly 765-kV long-range transmission plan will provide the Midwest region with at least a 1.9:1 benefit-cost ratio, a metric that was greeted with skepticism by Independent Market Monitor David Patton.

MISO’s Independent Market Monitor debuted six new market recommendations this year as part of his annual State of the Market report.

NEPOOL held its annual summer Participants Committee meeting in New Hampshire during a multiday stretch of extreme heat and high demand on the New England grid.

ERCOT’s Board of Directors has passed one contentious protocol change and tabled another that have divided stakeholders and staff and led the IMM to argue against the heavy use of ECRS.

MISO’s Independent Market Monitor continues to cast doubt on the theoretical benefits estimates of the second long-range transmission projects as the RTO intends to add more projects to the already $17 billion to $23 billion portfolio.

ERCOT staff and the ISO's Market Monitor have set aside their differences and promised to work together in improving the procurement and deployment of ancillary services.

MISO and its Independent Market Monitor agree legal action is likely concerning the RTO’s payments to SPP for a market-to-market flowgate.

ERCOT stakeholders have endorsed the grid operator’s proposed ancillary service methodology for 2024, but only after extracting a commitment from staff to bring the proposal back for further review.

Doubts continue to swirl around which version of MISO’s future fleet mix is appropriate for long-range transmission planning — the Independent Market Monitor’s or the RTO’s itself.

Amid the Independent Market Monitor’s denunciation of MISO’s fleet assumptions for long-term transmission plans, lead planners defended their approach to planning for 2040.
