In 2010, Nexamp was awarded contracts to install solar photovoltaic systems at 13 water and wastewater treatment plants in Massachusetts, whose energy consumption was a huge drain on municipal budgets. The projects were completed under the Massachusetts Solar Stimulus initiative, funded through the American Recovery and Reinvestment Act. Every year, Massachusetts' 370 water and wastewater facilities consume more than 1 billion kilowatt-hours, emitting 1 million tons of carbon dioxide. This project is part of the 4.5 megawatts of solar installed under the initiative which save the Commonwealth $1.7 million annually.
