Ensuring a Reliable Energy Transition
The PJM electrical grid, spanning 13 states and Washington, D.C., has been keeping the lights on for its customers for nearly a century, and its generation fleet is expecting to undergo a historic transformation to more renewable energy sources that rely on wind and sun to produce energy.
PJM has embraced this transition through its five-year strategy, producing intensive research and analysis on the opportunities and challenges presented by such a seismic shift. PJM and its stakeholders from throughout the energy industry have been hard at work smoothing the way for the transition by evolving our market rules, streamlining the planning process for new generators and engaging with states to put their clean-energy policies into action.
And that work will continue. Ensuring a Reliable Energy Transition describes PJM’s role as an independent regional transmission organization in identifying challenges to the nonstop delivery of electricity – a concept we refer to simply as “reliability” – and crafting solutions to those challenges amid the ongoing shift to solar, wind and other generators that increasingly rely on renewable energy sources.
Through this initiative, PJM will clearly articulate its concerns and propose an initial set of actions to be taken to keep the power flowing through this energy transition. Development and implementation of these solutions can only be accomplished in concert with all stakeholders and government partners.
Changes and Challenges Require Action
PJM and its stakeholders have taken concrete actions to usher in the energy transition with the following actions, among others:
- Development of new rules to remove barriers to renewable resources participating in PJM’s capacity market
- Groundbreaking work with the state of New Jersey to advance the buildout of its ambitious offshore wind program
- Rewriting interconnection rules to speed the entry of thousands of renewable generators flooding our planning queue
- Collaboration with states on a way for them to buy clean energy through a regional and centralized procurement or market system
At the same time, PJM has embarked on research to evaluate the anticipated changes to the system and any challenges they may present, and to begin to work with stakeholders on solutions. Building on a foundation of this research, analysis and stakeholder exchange over the past several years, and informed by lessons learned from Winter Storm Elliott in December 2022, PJM recently outlined a set of emerging risks to reliable electrical supply.
Specifically, while electricity demand continues to rise with the proliferation of energy-intensive data centers and electric vehicles and heating systems, more than 20% of PJM’s generators (~40 GW) are expected to retire by 2030. At the same time, the new renewable generation resources expected to replace them are successfully completing the PJM interconnection process but are not being built.
Ensuring a Reliable Energy Transition proposes an initial set of actions to support reliability that PJM can take independently and with its stakeholders, government and industry over the immediate, near-term and upcoming time frames to keep pace with these trends:
PJM’s work internally and with stakeholders and state/federal policymakers includes the following critical-focus tasks that will maintain reliability by:

Energy Transition in PJM: Resource Retirements, Replacements & Risks PDF
2.24.2023
Phase 3 of PJM’s ongoing study of impacts associated with the energy transition explores the pace of resource retirements and replacements through 2030 and highlights potential reliability risks to meeting growing electricity demand. The analysis shows that 40 GW of existing generation are at risk of retirement. The study’s projections indicate that the current pace of new entry would be insufficient to keep up with expected retirements and demand growth by 2030.

In PJM’s role as a NERC regional planning authority, and in response to the new Climate and Equitable Jobs Act in Illinois, PJM conducted a study to determine impacts to the transmission system resulting from anticipated generation retirements in Illinois through 2045. PJM identified several transmission upgrades that will be needed as Illinois generation retires or is phased out. For reliability reasons, PJM noted that it may need to request that certain units be permitted to operate beyond their desired deactivation dates.
