For business

What is Eversource Energy?

Eversource Energy currently serves nearly 4 million electric and natural gas customers in New Hampshire, Massachusetts, and Connecticut. Each of Eversource Electric’s three service territories provides specific towns with gas and electricity. For example, New Hampshire includes 211 towns that cover 5,628 square miles. In Massachusetts, coverage is available for 140 towns, which natural gas coverage for 51 towns. Connecticut’s territory has 149 towns covering 4,400 square miles, which includes 74 towns for natural gas.

Founded in 1966, Eversource Gas and Energy generates, transmits and distributes electricity and natural gas. The company initially launched as Northeast Utilities, and, in 2015, the company announced its plan to adopt Eversource Energy as its corporate name.

Understanding CT, MA and NH's deregulated market

The US Energy Information Administration (EIA) teaches us that, out of the six states comprising New England, Vermont is the only one that isn’t a deregulated market. When states have deregulation, that means customers can choose among competitive energy suppliers and their utility for electricity and natural gas. So, if you find a rate and plan you like better than what you currently have, deregulation gives you the power to switch. (Note, however, that if you’re still in a contract with your supplier, you could be charged an early termination fee.)

What is Eversource Energy's price to compare?

The price to compare is what a utility company charges as its electricity-supply rate.  When customers look at their utility bills, they’ll see a separate supply cost broken down in kWh for electricity or Therm for gas. As of Feb. 1, 2020, Eversource’s price to compare electric rate is 8.306 cents per kWh. If you find companies with lower supply rates, you should consider a switch.

What is the difference between a utility and a supplier?

When talking about utility companies, you might hear them referred to as Electric Distribution Utilities (EDUs) or Transmission and Distribution Service Providers (TDSPs). These companies, including Eversource Utilities, own and are responsible for maintaining utility poles. If the power goes out, this is also the company you contact. Some utilities outside Texas also generate electricity and are suppliers.

The supplier does not deliver power to your house. Regardless of which company supplies your power, your utility will deliver it. Even under deregulation, you cannot choose your utility.

Which suppliers are available in Eversource Energy's service area?

This depends on the territory. For example, if you’re looking for a supplier in New Hampshire, examples include Clearview Energy and Direct Energy. Enter your ZIP code above to see what’s available in your area.
