Somerville Announces New Community Choice Electricity Program

Program aims to reduce electricity costs while introducing renewable energy sources

SOMERVILLE— The City of Somerville will start a new electricity bulk buying program for households and businesses citywide this July. Called Somerville Community Choice Electricity (Somerville CCE), the goal of the program is to reduce and stabilize the cost of electricity for residents and businesses in Somerville, as well as increase the share of renewable “green” energy in Somerville’s electricity supply. Somerville will be joining more than 60 Massachusetts cities and towns that take advantage of state law that allows them offer this type of “municipal aggregation” program.

Over the duration of the 30-month program, Somerville ratepayers are expected to save on monthly electricity costs relative to the default rate from Eversource (formerly NSTAR). As with all municipal aggregation programs in the country, there is no guarantee of cost savings because Eversource adjusts rates twice annually while the Somerville CCE program locks in rates for 30 months. However, ratepayers will be insulated from market fluctuations, which occurred in recent winters, and program participants may leave the program at any time with no termination fee. When the program begins in July 2017, Somerville ratepayers will be saving money. The Somerville CCE rate will be $0.10538/kWh, versus the filed Eversource rate of $0.10759/kWh.

Increasing Our Use of Green Energy

In addition to stabilizing and reducing costs, Somerville CCE will bring more renewable energy to Somerville’s supply. The default supply will contain 5% more renewable energy than what is currently required by the State of Massachusetts. In addition, ratepayers have the option to either increase their renewable energy percentage to 100%, or drop down to the minimum state requirement. Transitioning the community’s electricity supply to renewable sources is critical to the City’s goal to become carbon neutral by 2050, as 22% of Somerville’s greenhouse gas emissions are estimated to come from grid-supplied electricity.

How Does Electricity Aggregation Work?

Municipal aggregation harnesses the bulk buying power of ratepayers to secure a low, fixed rate for electricity. Communities have been aggregating electricity since 1997, and more than 60 cities and towns in Massachusetts—including Lowell, Melrose, New Bedford, and Salem—already have active electricity aggregation programs. These communities, and Somerville, developed their aggregation plans in accordance with Mass. General Law c.164, sec. 134, which authorizes any municipality to aggregate the electrical load of interested consumers within its boundaries.

How the Somerville CCE Program Works

  • All Somerville ratepayers will receive a notification letter in on June 1. Letters include a mail-in opt-out card, with pre-paid postage.
  • Ratepayers will be automatically enrolled 30 days after notification, unless they choose to opt out of the program in advance.
  • Once enrolled, at any time during the program, customers may leave the program with no penalty.They will be returned automatically to Eversource supply.
  • Bills and service are still issued and provided by Eversource. Program participants are still Eversource customers, and Eversource is still responsible for emergency response and maintenance.
  • Rates are fixed from July 1, 2017 to December 31, 2019. When the program ends, Somerville has the option to go out to bid again for a second round of the program.
  • Ratepayers have the option to increase their supply to 100% renewable energy ($0.13198/kWh), or drop down to the state minimum requirement for renewable energy ($0.10398/kWh).
