MISO is planning a study to ensure external resources bordering more than one of its local resource zones participates in only one zone.

MISO, commited to moving forward, said it plans to refile a plan to create external capacity resource zones with FERC by the end of the month.

FERC rejected MISO’s proposal to create external zones for its annual capacity auction but left the door open for a revised plan in the future.

At last week's MISO Resource Adequacy Subcommittee meeting, staff reviewed how capacity import limits can bind in the RTO's annual capacity auction.

MISO’s plan to create external resource zones in its annual capacity auction isn’t detailed enough on several fronts, FERC told the RTO.

MISO’s Market Monitor floated a plan that would allow resources that are unavailable for the full planning year to offer into the RTO’s capacity auction.

Stakeholders said they foresee MISO making multiple changes to its markets to accommodate energy storage in response to FERC Order 841.

A recent MISO study slightly overestimated actual capacity offers in the 2018/19 Planning Resource Auction.

MISO reported clearing 135 GW of capacity, with nine of its 10 local resource zones clearing at $10/MW-day.

After almost three years of deliberation, MISO is putting the final touches on a plan to create external resource zones for its annual capacity auction by 2019.
