MISO, PJM and SPP have failed for years to find a suitable replacement for a 20-year-old system reference they use to portion out flow rights on their system, the so-called freeze date.

The MISO Board of Directors hit the high notes of resource adequacy anxiety, a possible new member with experience at Southern California Edison and an annual budget that will creep past $400 million.

MISO said it managed a milder summer overall compared to previous years, though it weathered two hurricanes and escalated into emergency warnings during a heat wave.

MISO’s quarterly public meetup with its board of directors put on display the unrelenting rift between the RTO’s planners and the Independent Market Monitor over MISO’s $21 billion in long-range transmission planning.

MISO’s new day-ahead market clearing engine should move into standalone production near the end of September following a delay in testing, RTO executives said.

MISO’s $25 billion, mostly 765-kV long-range transmission package for the Midwest region is nearing finalization, while the Independent Market Monitor continues to doubt the necessity of the projects.

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

MISO said its cost of doing business is set to escalate within the next four years, spawning bigger operating budgets and heftier member dues.

MISO’s system is at the mercy of faster interconnections of new resources and retirement delays, executives said in a quarterly address to the board and stakeholders.

MISO and its board are scrutinizing the steps they can take to preserve institutional knowledge on the board of directors as they confront half of board members reaching term limits this year and next.
