In 2010, Nexamp was awarded contracts to install solar photovoltaic systems at 13 water and wastewater treatment plants whose energy consumption was a huge drain on municipal budgets. The projects were completed under the Massachusetts Solar Stimulus (MaSS) initiative, the state’s largest solar procurement.
At the time of its installation, the system at Chelmsford Spring Water District was the Commonwealth’s largest ground-mounted solar array. The 485.1 kW solar plant generates enough annual electricity to offset 844,680 lbs. of carbon dioxide, and provides approximately half of the power for the water treatment facility.
