The Maryland Public Service Commission (PSC) requires that all Small Generator Interconnection equipment connected to BGE's electric utility distribution system be approved by the requirements of Section 20.50.09 of the Code of Maryland Regulations.
Customers with residential small generator equipment that are not connected to a power grid are not required to apply to BGE for approval to interconnect. Similarly, customers with back-up generators used during outages only (for 100 milliseconds or less) do not need to apply.
These regulations ensure that anyone that wants to install generators up to 10,000 kW have a consistent way of applying to BGE for interconnection using standard applications.
Maryland Standard Small Generator Interconnection Rule
Wind turbines, photo voltaics (PV), small gas-turbine generators, fuel cells, solar panels, small internal combustion-engine generators (ICE), and steam turbine units (cogeneration).
Any customer moving in to a premises with an existing, net-metered generation system is required to take ownership and responsibility of the system. Please familiarize yourself with all rules and policies regarding small generator interconnection before submitting the change form below.
