  • Maryland Net Energy Metering and Small Generator Interconnections

  • We support renewable energy and partner with our customers to ensure safe and reliable interconnection of renewable energy into the electric grid.

    Code of Maryland Regulations (COMAR) 20.50.09 for Small Generation Interconnection Standards and COMAR 20.50.10 for Net Metering Authority define the small generator interconnections application processes Delmarva Power follows. Small generator technologies that qualify for interconnection with our system include solar (photovoltaic or “PV”), rooftop solar, wind, biomass, fuel cells, qualifying closed circuit hydro-electric, and micro-combined heat and power.

    The two-part interconnection application process  connects your renewable generator system to the electric grid. This complex process takes approximately 77 business days from when Delmarva Power receives your complete application to when Delmarva Power issues your Authorization to Operate, including the time during which your contractor installs your solar array or other renewable generating system.
