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 who anyone that wants to install generators has a consistent way of applying to BGE for interconnection using standard applications.
Maryland Standard Small Generator Interconnection Rule
Examples of Interconnection equipment include:
Wind turbines, photovoltaics (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.
If you have any additional questions regarding BGE’s Small Generator Interconnection Agreement or net metering, please email your question and contact information to
The first step in the application process is to determine whether your equipment falls under the scope of Maryland regulations that require an application to be submitted to BGE to interconnect.Any small electricity generator facility that will be interconnected to an electric distribution system that is owned or operated by an electric company in Maryland and meets the following criteria must be registered:
If your generator application falls under the regulations outlined above and will be electrically connected in BGE's service area, you must
apply to BGE for approval to interconnect. If a generator exceeds 2,000 kW, you may be required to file a Certificate of Public Convenience and Necessity (CPCN) with the Maryland Public Service Commission (MD PSC). Please refer to the
MD PSC Website CPCN Exemptions: Frequently Asked Questions for more information about these requirements.
Level 2: $50 plus $1 per kW of rated generating outputLevel 3: $100 plus $2 per KW of rated generating outputLevel 4: $100 plus $2 per KW of rated generating output

As a final step, BGE will send you a
Certificate of Completion (PDF, 17 KB). It contains information about the interconnection equipment to be used, its installation, and should include proof, such as a copy of a certificate of inspection, that the installation has been inspected and approved by the local inspection authority. You must complete and return the certificate to BGE after the installation is completed and final electrical inspector approval has been obtained.
