Renewable Distributed Generation (25kW-150kW)

Middleborough Gas and Electric Department offers Renewable Distributed Generation (RDG) for solar arrays sized 25kW-150kW AC. Solar arrays that fall within RDG guidelines, will receive a quarterly check or possible account credit for any excess generation produced.

In order to qualify for a rebate, all Solar RECs must be committed to MGED’s portfolio. MGED is currently offering a solar rebate of $0.50/W (not to exceed $50,000). RDG rebates are paid-out over four (4) years. MGED Rebate Application 

An Interconnection Application (PDF) must be submitted to MGED for pre-approval and to apply for eligibility on the RDG solar array to receive a MGED Reservation Letter which would verify if your qualified for a rebate. MGED will require a circuit study which a fee will apply. The cost of which will vary based on the size of the proposed array.

Please read the RDG Guide (PDF) thoroughly before applying for interconnection.


Any proposals for solar arrays larger than 150kW, must be presented to MGED management for consideration. Please call Dani Taylor at 508-947-1371 or send an email to: [email protected] for more information.

    • After installation is complete, the system owner or their contractor should call the town wiring inspector for a final inspection.

System Inspection
