Why PJM Now

Solar is Now a Capacity Resource in PJM

PJM is the largest wholesale electricity market in North America, and capacity prices have reached record highs. As of 2025, FERC eliminated the must-offer exemption for intermittent resources, meaning operational solar assets with Capacity Interconnection Rights are now required to participate in PJM's capacity market. Combined with an interconnection queue dominated by solar, the revenue and compliance stakes for solar asset owners have never been higher.

$333/MW-day
Record BRA Clearing Price
The 2027/28 Base Residual Auction cleared at the highest price in PJM's history, and solar with CIRs now participates directly in that capacity market.
Mandatory
Capacity Must-Offer Now in Effect
As of February 2025, FERC eliminated the RPM must-offer exemption for intermittent and storage resources. Operational solar projects with CIRs must now offer into PJM's capacity auctions.
Solar-Led
Largest Share of PJM's Queue
Solar and solar-plus-storage make up the largest share of PJM's interconnection queue, with the bulk of new capacity targeting commercial operations through the late 2020s.

5 Questions to Ask Any PJM Solar Operator

The answers will tell you more about an operator's service model than any capabilities presentation.

1
Are you a registered PJM Market Participant?
Only registered Market Participants can represent assets in PJM's wholesale markets. Operators who rely on a third-party MP structure, or who are not registered at all, add complexity and counterparty risk that shows up in your asset's market access and revenue reliability.
2
Can you manage curtailment and DNE in real time?
Solar assets face curtailment orders and Do-Not-Exceed limits that shift with grid conditions. Without low-latency RTU telemetry and 24/7 dispatch, your asset risks non-compliance penalties and avoidable lost generation. Ask how the operator responds to dispatch signals minute to minute.
3
How do you handle the new RPM must-offer requirement?
Capacity participation is no longer optional for solar with CIRs. Ask specifically how your operator manages MSOC determination, ELCC accreditation, and the annual UCAP filing calendar. A missed window carries real revenue and compliance consequences for the entire delivery year.
4
Do you own and operate your own 24/7 NOC?
Continuous monitoring and dispatch is a PJM operational requirement, not an option. Operators who outsource NOC functions or provide only business-hours coverage cannot meet PJM's real-time availability and telemetry standards, which directly affects compliance and revenue.
5
Will you get a high level of customer service?
Scale without service quality is a liability. Having direct access to the person actually managing your asset matters more than portfolio size alone.

FAQ

Frequently Asked Questions

Key questions about solar generation operations and market participation in PJM, answered.

Yes. In February 2025, FERC approved PJM's proposal to eliminate the must-offer exemption for intermittent and storage resources. All operational solar projects with Capacity Interconnection Rights are now required to offer into PJM's Reliability Pricing Model (RPM), beginning with the 2026/27 Base Residual Auction. Projects still in development must participate immediately upon reaching their commercial operation date. SYSO manages qualification, MSOC strategy, and every pre-auction deadline so your asset stays compliant.
PJM uses an Effective Load Carrying Capability (ELCC) methodology to accredit solar. Because solar generation tapers off during the late-afternoon and evening hours when PJM's reliability risk is highest, solar ELCC ratings are modest and tend to decline as more solar is added to the system. Accurate accreditation, and pairing solar with storage to lift it, directly affects how much capacity revenue your asset can earn.
Curtailment is the intentional reduction of a solar asset's output due to grid constraints or oversupply; Do-Not-Exceed (DNE) dispatch limits cap real-time output based on grid needs. Both reduce the energy you can sell. Meeting them requires advanced telemetry and remote RTU control so the asset can respond to dispatch signals in real time, minimizing lost generation while staying compliant. SYSO's 24/7 NOC manages this continuously.
PJMNet is PJM's private wide-area network connecting generation assets to PJM's control centers, and ICCP transmits real-time operational data between your asset and PJM. Every solar asset in PJM's wholesale markets requires validated ICCP telemetry to receive dispatch and curtailment signals, report output, and settle accurately. SYSO operates dedicated PJMNet ICCP infrastructure that new assets onboard onto, eliminating the months-long process of building and validating a standalone connection.
Grid-connected solar earns primarily through the Day-Ahead and Real-Time energy markets, selling generation at locational marginal prices, plus now-mandatory capacity revenue through the RPM auctions and environmental attributes such as RECs and SRECs. Pairing solar with battery storage opens additional value through clipping recovery, energy arbitrage, and improved capacity accreditation.
For many PJM solar projects, adding co-located storage is increasingly compelling. A paired BESS can capture energy that would otherwise be clipped by the inverter or lost to curtailment, shift generation to higher-price hours, and meaningfully improve capacity accreditation. SYSO co-optimizes dispatch across the solar and storage components to maximize total asset revenue.
