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.

After two requests for more information and nine months, FERC has greenlit MISO’s plan to exchange its current, vertical curve for sloped demand curves in its seasonal capacity auctions.

Members of MISO’s Advisory Committee emphasized that all players in the footprint need to act swiftly to position themselves for “hyperscale” load growth and the EPA’s new carbon rule.

MISO reaffirmed its commitment to its second, $25 billion long-range transmission portfolio while stakeholders asked the RTO to be mindful of river crossings and whether it may reassign developers for the first LRTP portfolio’s projects in Iowa.

Two years after announcing its $1.8 billion Joint Targeted Interconnection Queue transmission portfolio with SPP, MISO is putting final touches on FERC filings to make it happen.
