Peterborough, N.H. is building a 947-KW solar array—the state's largest photovoltaic system and first solar-on-landfill project. The array is sited on former sewer lagoons at the town's wastewater treatment facility.
The project has no up-front costs, thanks to a $1.2-million grant approved on Jan. 15 by the state Public Utilities Commission Renewable Energy grant program and financing through a power purchase agreement with Water Street Solar 1.
