ENERGY AGGREGATION

Electricity Supply Aggregation

Project Overview
The goal of the Nashua Region Electricity Supply Aggregation is to purchase electricity as a group from a competitive supplier at a lower rate than each member could receive on its own. By purchasing as an aggregation, municipalities and school districts can offer electricity suppliers a larger demand than if they each tried to purchase electricity individually. The larger demand, in turn, allows suppliers to offer a better rate to the aggregation than it could to individual members.

The Nashua Regional Planning Commission serves as an aggregator to facilitate a bid process among competitive electricity suppliers licensed with the NH Public Utilities Commission. Each aggregation member signs its own contract with the supplier for a fixed electricity supply rate. Rates and contracts are identical for each member within a given electric distribution territory.

Project History
In 2011, NRPC utilized funding from the Energy Technical Assistance and Planning (ETAP) program to work with 9 towns and 6 school districts to form an aggregation to procure electricity from a competitive supplier. Since that time, the aggregation has completed the following contract rounds:
