Peterborough Solar Project: Summary & Basic Timeline

With overwhelming support and enthusiasm from the public, the Town of Peterborough is currently building the largest solar array in the state (944 kW DC). The project is being funded by a $1.22 million PUC grant, with the remaining $1.4 million in total project costs being covered through a long-term power-purchase agreement (PPA) with Borrego Solar.  Upon completion, this array will power our newly constructed wastewater treatment plant located off of Rt. 202 and help offset energy costs for other municipal buildings.  The project is anticipated the save the town an estimated $250,000.00 to $500,000.00 over the next two decades.   This savings will be achieved through a long-term power-purchase agreement with Borrego Solar that enables the town to purchase power at a discounted rate (8 cents/kWh versus 14 cents/kWh) and new state rules regarding “virtual” net metering.   Basically, “virtual” net metering allows for the benefits of energy captured at one site (in this case the Peterborough WWTF) to be shared among other buildings not directly attached to the energy capturing site.  This model enables a large-scale solar project to help offset the cost of purchasing energy elsewhere, as excess energy is captured and essentially sold back to the larger energy grid.

* Phase 1 of the project is currently under-way, with the former WWTF lagoons undergoing a filling process to make way for the new array

* Phase 2 of the project is tentatively scheduled to begin in mid-November, with actual construction of the array to get under-way

* The project is expected to be complete and functional in the spring of 2015
