ISO Capacity Markets

FERC Order 2222 created the opportunity. Your program needs the infrastructure.

ISO capacity markets offer substantial revenue for community solar operators who can qualify their DER portfolio as an ISO-recognized capacity resource. Nexwatt provides the technical pathway.

Market Coverage

The markets Nexwatt supports

PJM

Basic Residual Auction (BRA) and Reliability Pricing Model. Largest capacity market in North America covering 13 states and DC.

Key requirements: ICAP qualification, metering accuracy, dispatch telemetry

ISO-NE

Forward Capacity Market (FCM). New England's annual capacity auction with strict DER aggregation telemetry requirements.

Key requirements: DER aggregation registration, real-time telemetry, dispatch testing

NYISO

Installed Capacity (ICAP) market. New York's capacity market with specific DER aggregation tariff provisions post-FERC 2222.

Key requirements: ICAP qualification, DRIS registration, telemetry compliance

Regulatory Context

FERC Order 2222: What it means for your program

Issued in September 2020, FERC Order 2222 requires all organized wholesale electricity markets — including PJM, ISO-NE, NYISO, MISO, CAISO, and SPP — to allow distributed energy resource aggregations to participate directly in capacity, energy, and ancillary service markets. This was a landmark ruling that opened the door for community solar programs to compete alongside traditional generation for capacity market revenue.

The critical detail: Order 2222 required ISOs to file compliance tariffs, but each ISO sets its own aggregation rules — minimum size thresholds, telemetry standards, dispatch capability requirements, and registration procedures. PJM filed its compliance tariff in 2023. ISO-NE and NYISO have each filed with materially different requirements.

For a community solar program operator, navigating three different ISO compliance frameworks — each with its own telemetry format, documentation requirements, and dispatch testing procedures — is the central technical challenge. That complexity is precisely what Nexwatt was built to abstract.

Qualification Process

ISO capacity qualification: the required steps

01 DER inventory filing and metering validation
02 ISO DER aggregation registration
03 Telemetry system testing and approval
04 Dispatch capability demonstration event
05 Capacity auction enrollment and offer submission

Nexwatt manages steps 1 through 4 on behalf of program operators — handling the documentation, testing coordination, and ISO correspondence that typically takes 4–6 weeks of internal staff time.
