About Eversource

Founded in 1966 as Northeast Utilities, Eversource is Massachusetts' oldest and second largest utility company. It's also the largest in New England, serving New Hampshire and Connecticut as well. After its 2012 merger with Boston-based NSTAR, the company, which had already owned Western Massachusetts Electricity Company (WMECo) became Eversource Energy with 4M electricity and natural gas customers throughout its three service states. In Massachusetts, Eversource has Eastern and Western divisions, together serving over 1.3 million electricity customers across 140 communities. It delivers electricity to all customers on a monopoly basis and is required by state law to provide a so-called "basic service" supply to customers who have not chosen their own choice of supply.

Municipally–owned electric companies (Municipal Light Plants)

Depending on where you live, you may not get service from any of MA's three main investor-owned utility companies. Instead, your city or town has a municipally–owned electric company, or Municipal Light Plant (MLP).

Municipal aggregation or Community Choice Electricity

Even if you don't live in an MLP community, municipalities in Eversource, National Grid and Unitil territories can seek approval from the Massachusetts Department of Public Utilities to offer an aggregation service—often referred to as Community Choice Electricity—to its residents and/or businesses.

Electric supply companies and the supplier marketplace

As long as you are not served by an MLP, you can shop for supply outside of your electric utility and possibly find better value in the electricity supplier marketplace

Perch helps you navigate the electricity supplier options to find you a great deal

Let Perch handle everything for you.

  • We analyze your electric bill to understand your current costs.

  • We continuously monitor the supply marketplace to find you a lower rate than similar options in your area, based on your desired energy preference (remaining on a mixed energy plan typically leads to greater savings while going 100% green energy has a greater environmental impact).

  • You won't notice any interruptions to your service—our automated matching technology seamlessly works behind the scenes.

And we don't stop after we find you a low-cost plan. We'll continue to monitor the market and automatically switch you if a cheaper plan becomes available that matches your energy preference.

Massachusetts utilities and aggregations using renewable energy

In Massachusetts, it's required that all electricity companies get a certain percentage of their energy from renewable sources. This is thanks to the Renewable Portfolio Standard (RPS), established in 1997 to ensure utilities and electricity suppliers are investing in sources like solar, wind and hydro as more environmentally friendly power generation for their customers—and also a more recent Clean Peak Standard. Massachusetts has continuously updated its RPS and Clean Peak percentages, recently totaling 51% (2022), and potential new legislation could accelerate that percentage even more in future years.

How Perch helps you support renewable energy in Massachusetts

Support cleaner energy generation and fight climate change by joining a community solar project

  • Perch will help you subscribe to a solar farm in your area (subject to eligibility and availability).

  • While you won't be receiving solar electricity directly to your home, you'll be supporting the addition of more solar power to the overall energy mix on the grid—lessening the reliance on dirty, harmful fossil fuels.

  • In exchange for supporting operations of that solar farm, you'll receive a discount on your electricity bill in the form of credits.

  • You're guaranteed to see annual savings on your electricity cost thanks to the credits.

Get matched to a local solar farm and save on your electricity costs.
