Nexamp's solar + storage project with IBEW Local 103 in Dorchester, MA builds on IBEW's history of strong environmental stewardship and leadership. Located behind IBEW's meter, the system is expected to produce 265,000 kWh of electricity per year, meeting over 60% of the building's electricity needs with clean energy. Pairing the array with a 100 kW/210 kWh AC-coupled, lithium-ion battery energy storage system will allow IBEW to store electricity produced by the solar array to use when it is most needed, meeting peak demand and reducing demand charges by up to 33%. ​
