FERC accepted CAISO’s proposal to allow for storage resources to bid above the ISO’s $1,000/MWh soft offer cap in the real-time market to account for their intraday opportunity costs.

June brought a 2-GW lower peak than anticipated and unchanged real-time and fuel prices from last year, MISO said in a monthly operations report.

As ISO-NE undertakes major capacity market accreditation reforms, New England storage developers are voicing concerns that potential flaws in the RTO’s modeling methodology could discourage new investments in storage resources.

The PJM MRC endorsed one of two proposals to revise how the RTO uses reserve resources, approving a deployment scheme where instructions are sent by basepoints, while rejecting a parallel proposal to grant operators the ability to dynamically increase market procurements.

NYISO analysts continue to recommend a two-hour battery electric storage system resource as the proxy unit for the ISO’s capacity market demand curve.

The D.C. Circuit Court of Appeals rejected Entergy’s challenge of MISO’s seasonal capacity accreditation and generator outage rules, two years after FERC approved the rules.

FERC said it needs more explanation behind MISO’s plan to use a capacity accreditation that would accredit resources based on a combination of their projected availability and historical performance during periods of high system risk.
