  • Connecting Your System to the Grid

  • 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 Delmarva Power’s electric grid, pay an application fee, have your new system installed and then inspected by the Delaware Real Estate Commission (DREC), and have a net-capable Delmarva Power 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 Delmarva Power 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 Net Energy Metering and Small Generator Interconnections Checklist.

    COMPLEting the Right Application

    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. 

     
    Inverter NAMEPLATE CAPACITY Delaware APPLICATION AND AGREEMENT level
     
    10 KW OR LESS and inverter-based
    LEVEL 1
     
    2 MW or less FOR RADIAL DISTRIBUTION CIRCUIT OR SPOT NETWORK SERVING ONE CUSTOMER
     LEVEL 2 
    does not export power
    50 kw or less for area network
    10 mw or less for radial distribution Circuit
     Level 3 
     
    10 mw or less and not level 1, 2 or 3
    level  4


    Customers requesting aggregated net energy metering or community net energy metering will need to submit the appropriate-level interconnection application and agreement plus the anem or cef application rider.  

    Application Fees

    Once your application has been received, Delmarva Power’s application system automatically determines if a fee is required and calculates it based on the jurisdiction, system size, and application level.
