Market participants remain skeptical of a MISO plan to integrate external resource zones into its annual capacity auction.

MISO presented stakeholders with a proposal to tighten rules on capacity imports amid uncertainty over a recent appellate court ruling.

MISO has adopted the Independent Market Monitor’s recommendation to base pricing of external capacity resources on bordering balancing authorities.

MISO released details of its forward auction proposal last week while also proposing the addition of six external resource zones.
