Sales and Marketing

Financial Performance

Eversource has recorded a continuous increase in revenues over the last five years.

In 2014 net revenues increased by 6% due to growth across all of the company’s reportable segments.

The most significant factor in the increase in revenues relates to cost tracking mechanisms for the recovery of higher costs associated with the procurement of energy supply, which increased $506.8 million and $126.9 million for electric distribution and natural gas distribution, respectively impacted by the overall New England wholesale energy supply market, partially offset by decreases in transition cost recovery revenues.

Natural gas distribution revenues increased due to higher sales volumes driven by colder weather. Base electric distribution revenues declined due a drop in retail electric sales volumes, driven primarily by the cooler summer weather.

Transmission revenues increased due to the recovery of higher revenue requirements associated with ongoing investments in transmission infrastructure, partially offset by the impact of net reserve recorded in 2014 as a result of the FERC change in measuring the return on investment at utilities.

The company also recorded a strong income from 2010-2014.

In 2014 Eversource's net income increased by 4% due to a reduction in the amortization of regulatory assets.

Cash flows provided by operating activities decreased by 2% in 2014 due to the impact of Department of Energy damages proceeds resulting from the spent nuclear fuel litigation, the absence of 2013 cash disbursements for major storm restoration costs, the decrease in pension and related cash contributions, and changes in the timing of working capital items.  These impacts were more than offset by higher income tax payments in 2014 and the unfavorable cash flow impact resulting from lower recoveries from customers in 2014, relating to regulatory cost recovery tracking mechanisms.


Updating its brand to be more inclusive and flexible, in 2015 Northeast Utilities changed its corporate name to Eversource Energy.

That year Eversource, Spectra Energy, and Spectra Energy Partners announced that National Grid was joining Access Northeast, the innovative energy solution for New England, as a co-developer. Once Access Northeast is operational, it is projected to save electric customers an average of $1 billion a year during normal weather conditions and even more during severe cold weather. This alliance will provide New England natural gas distribution companies and generators with additional access to natural gas supplies from multiple, diverse receipt points along the Algonquin pipeline system, including the Iroquois pipeline system.

Eversource projects to make capital expenditures of about $8 billion from 2014 through 2017, out of which it plans to invest $3.5 billion in its electric and natural gas distribution segments and $3.7 billion in its electric transmission segment.
