Using Clean Energy to Produce Clean Water

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.The nearly 4,000 modules installed produce one million kilowatt hours annually and complement a wind turbine project to reduce the water pollution control facility’s energy costs and carbon footprint.
