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.

New York will be short 1 GW of resources by 2034, driven by increased demand, large load growth and lack of natural gas, according to the preliminary results of NYISO's biennial Reliability Needs Assessment.

MISO has multiple planning topics to tackle on the horizon, with work involving an update of merchant HVDC interconnection procedures, making expedited transmission project reviews more manageable, and evaluating co-located load and generation seeking interconnection.

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.

FERC approved NYISO’s proposed tariff revisions to more accurately accredit natural gas resources’ capacity, but the commission delayed their implementation until 2026.

MISO plans to pursue a more straightforward, 50% peak load megawatt cap to limit the number of generator interconnection requests it will accept annually.
