MISO summer planning reserve margins will remain firmly above requirements even after it shaved nearly half a percentage point.

MISO expects a 19.2% planning reserve margin this summer, well above its 15.8% requirement, and a percentage point above its projection last year.

SPP’s Regional State Committee (SPP RSC) accepted a working group’s proposal to leave unchanged their safe-harbor thresholds.

MISO will have a 15.8% planning reserve margin for the 2017/18 planning year, up slightly from last year, according to the RTO’s loss-of-load-expectation study.

The SPP Capacity Margin Task Force conducted its penultimate meeting  as it continues to set up the stakeholder group that will replace it.

Independent Market Monitor David Patton asked MISO’s Board of Directors to suspend the RTO’s work on the proposed redesign of its capacity auction.

MISO has adequate capacity to meet summer demand, though there’s a good chance the RTO will dip into its load-modifying resources.

The SPP board of directors' approval of the RTO’s first reduction in its planning reserve margin since 1998 almost left members wanting more.

SPP members voted last week to reduce the RTO’s planning reserve margin to 12% from the current 13.6%.

The SPP task force updating the RTO’s planning reserve margin requirements shared its draft report on loss-of-load expectations.
