FERC rejected SPP’s proposed Tariff revisions requiring load-responsible entities (LREs) to maintain sufficient capacity and planning reserves.

Planning reserve margins are expected to be adequate for a hotter-than-normal summer, FERC said in its annual summer reliability report.

SPP stakeholders approved a revision request that allows the RTO to lower its planning reserve margin as it waits on a quorum-less FERC.

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.
