How could the proposed Community Choice Aggregation legislation affect PJM Interconnection?
CCA legislation may require PJM Interconnection to adapt regional grid market mechanisms The legislation proposed by Representative Nathan Davidson would authorize Community Choice Aggregation (CCA) programs in Pennsylvania. These programs allow local governments to combine the electricity demand of residents and small businesses and purchase generation from competitive suppliers on their behalf. Since PJM Interconnection manages the regional wholesale electricity market and transmission across the area, the introduction of aggregated demand through CCA programs would necessitate changes to the existing regional grid market mechanisms to accommodate this new structure of demand.

How it reaches PJM Interconnection
-
Rep. Nathan Davidson introduced legislation in Pennsylvania to authorize Community Choice Aggregation (CCA) programs. These programs would allow counties or municipalities to combine the electricity demand of residents and small businesses to purchase generation from a competitive supplier on their behalf, while the existing utility maintains transmission and distribution services. The proposal aims to ease the burden of high electricity bills on residents and small businesses.

The facts so far
As reported. Each one links to where it comes from.
- The proposal would allow communities to shop on their behalf, potentially giving customers greater bargaining power and additional options to pursue competitive rates.sungazette.com
- CCA programs allow a county, municipality, or group of local governments to combine the electricity demand of participating residents and small businesses, and purchase generation from a competitive supplier on their behalf.sungazette.com
- The existing utility continues to provide transmission and distribution service under CCA programs.sungazette.com
Why it matters
The shift toward CCA represents a structural change in how electricity demand is managed and procured in Pennsylvania. For consumers, this could lead to greater bargaining power and competitive rates, especially given that residential electricity prices have risen sharply, increasing nearly 46% between 2018 and 2025. The success of this model depends on balancing local consumer choice with the stability of the regional grid.
For PJM Interconnection, which manages the complex regional wholesale market, this change in demand aggregation is significant. RTOs must ensure grid reliability while facilitating market competition. Adapting to CCA means integrating a new, locally-driven procurement method into the established regional market rules, which could affect operational planning and market design.
What we don't know yet
