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:

2012 Bid Process
• Contract period—12 month contract, February 2012-January 2013
• Total savings for aggregation members = $420,185

2013 Contract Renewal
• Contract period—12 month contract, February 2013-January 2014
• Total savings for aggregation members = $276,049

2014 Bid Process
• Contract period—9 month contract, February 2013-November 2014
• Total savings for aggregation members = $197,259

2015 Contract Renewal
• Contract period—8 month contract, March 2015-November 2015
• Total savings for aggregation members = $221,627

2016 Contract Renewal
• Contract period—12 month contract, November 2015-October 2016
• Total savings for aggregation members = $242,402

2017 Bid Process 
• Contract period—12 month contract, November 2016-October 2017 
• Total savings for aggregation members = $251,409

2018 Contract Renewal 
• Contract period—12 month contract, November 2017-October 2018 
• Total savings for aggregation members = to be calculated after default utility rates are set for contract period
