We support renewable energy and partner with our customers to ensure safe and reliable interconnection of renewable energy into the electric grid.
After you have
researched and selected the renewable generating system that best suits your needs and selected an installation contractor, you or your contractor will need to
apply to have your system interconnected to Pepco’s electric grid, pay an application fee, have your new system installed and then inspected by your local electrical inspector, and have a net-capable Pepco electric meter installed at your premise. This complete interconnection process takes approximately 77 business days. Interconnecting ensures that you will continue to have a supply of electricity coming into your home, even when your solar panels are not generating power – at night or when clouds, shade or snow limit generation. The net-capable meter ensures you will receive Pepco bill credits for generation your premise does not use and your system feeds into the grid.
The application process has several key steps to ensure a successful interconnection to the grid. We have provided these simple and easy-to-follow steps to help guide you with the process. You can also download our
Small Generator Interconnection Application Checklist for Maryland.

Your interconnection process starts with completing an
application and agreement based on your proposed system’s nameplate capacity. The table below lists the general interconnection criteria for each application and agreement level. The nameplate capacity is the
maximum output, expressed in kilowatts, of an electric generator under specific conditions designated by the manufacturer, as indicated on the nameplate physically attached to the generator.
Aggregated Net Energy Metering will need to submit the appropriate-level Interconnection Application and Agreement plus the
ANEM application rider. Customers interested in community solar energy can find more information
Once your application has been received, Pepco’s application system automatically determines if a fee is required and calculates it based on the jurisdiction, system size, and application level. The online system automatically creates and emails an invoice to the contractor or customer.
Pepco will communicate with you during the application process if the following documents are needed.
