Belmont Light recognizes that the decision to host an emission-free renewable distributed generation facility requires careful consideration of many economic and physical factors. Our distributed generation policy is designed to provide customers with flexibility of contract and fuel options while maintaining low rates for all customers and the reliability and safety of our system. If you have questions regarding our policy or rate, please do not hesitate to contact us. 

Before beginning installation, distributed generation host customers are required to submit an Interconnection and Service Agreement Application together with the application processing fee and a copy of the signed electrical permit. Qualifying systems include, but are not limited to:

  • Solar PV Systems
  • Battery Storage Systems or
  • Wind Turbines

Please email us at with any questions regarding the interconnection process.


Belmont Light shares its customers’ commitment to emission-free renewable energy. If you are considering installing solar panels or a wind turbine to supply energy to your home or business, please review our Policy on Emission-Free Renewable Energy Facilities effective December 1, 2015.

**The current policy replaces Belmont Light’s 2011 Net Metering and Buyback Tariff. Under the 2015 Policy, the buyback price for excess solar PV generated by new solar PV customers will change from Belmont Light’s full retail rate to 11 cents per kilowatt hour.**
