Restricted Circuit Map

Potomac Electric Power Company (PEPCO) supports renewable energy and is proud to partner with customers to ensure the safe and reliable interconnection of renewable energy into the electric grid.

In some regions, PEPCO might not have an open circuit at your location – or the circuit might be restricted or constrained, making additional interconnections unavailable or limited.  The map linked below ​shows general areas where circuits are restricted. Click here​ to access a searchable version; type an address into the search box to locate a specific location. If the address in which you are interested in falls within a restricted area, you may contact the PEPCO'S Green Power Connection Team for more details. Projects larger than the listed restriction may be approved following system upgrades, which would be at the developer's and/or customer's expense.

The technological, legal, and regulatory considerations that apply to interconnection of solar generation and other distributed energy resources are complex and constantly evolving. The map(s) linked above are for illustrative purposes only.  Although Atlantic City Electric, Delmarva Power & Light Company, Potomac Electric Power Company, and their affiliates make good faith efforts to keep online maps current, they cannot guarantee the timeliness or accuracy of the information.  Developers/customers must still apply for, and be granted, approval to install prior to beginning construction/installation of a proposed interconnection project.  Moreover, a location showing available capacity does not guarantee approval.  Furthermore, additional operating requirements or distribution system upgrades could be required, which would be at the developer's and/or customer's expense.  You are encouraged to seek appropriate technical, operational, financial, and legal advice before proceeding.
