Scaling Clean: This report draws on original RMI analysis as well as extensive discussions with PJM states, utilities, customers, and clean energy developers.
Spurred by state decarbonization policy, strong customer demand, and rapidly improving technology, carbon-free energy is playing a growing role in PJM, the United States’ largest wholesale electricity market. However, the pace of PJM’s energy transition is much too slow to avoid the worst impacts of climate change. To accelerate and sustain decarbonization while retaining reliability and affordability, PJM will need to better incorporate the capabilities and services of carbon-free resources in its markets
Through the Resource Adequacy Senior Task Force (RASTF), PJM stakeholders are considering significant changes to the RTO’s capacity market rules, including the creation of a voluntary clean energy market. In this report, we review two clean energy market designs under consideration (the Forward Clean Energy Market and Integrated Clean Capacity Market), share analysis that clarifies the opportunities that clean energy markets provide, and make recommendations to PJM and its stakeholders as they consider next steps.
Key Findings
- Accounting for the capacity value of clean energy resources lowers costs and reduces emissions.
- If we assume all market actors accurately account for the capacity value of clean resources, the two market designs and the status quo produce identical, “optimal” outcomes.
- State carve-out policies (e.g., policies specifying targets for specific technologies or in-state generation resources) have meaningful cost and emissions implications that should be considered together with their benefits.
- If a centralized clean energy market helped attract new buyers, the increased voluntary demand would accelerate clean energy deployment and fossil asset retirement.
Recommendations Based on Our Analysis and Conversations with PJM Stakeholders
- PJM and RASTF stakeholders should keep “clean procurement” in the task force’s scope and pursue reforms that remove barriers to the participation of clean energy resources in the capacity market.
- States should collaboratively define a standardized clean energy product that can be competitively procured throughout PJM, which could streamline clean energy credit transactions, lower costs, and accelerate emissions reductions.
- A regional clean energy procurement process should foster participation from all potential buyers, including cities and businesses with clean energy goals.
- PJM and stakeholders should prioritize approaches that accelerate near-term decarbonization, can adapt to a more deeply decarbonized grid, and are politically feasible.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
