Sales and Marketing

Residential customers accounted for about 45% of Eversource's total revenues in 2015; commercial customers, 31%.

Financial Performance

Eversource has recorded a continuous increase in revenues over the last five years. In 2015 the company's net revenue increased by 3% to $7.95 billion due to higher electric distribution segment revenues.

Electric distribution revenues increased primarily due to a Connecticut Light and Power base distribution rate increase, and higher retail sales volumes driven by weather impacts.

The company's net income has followed similar trend as net revenues over the last five years. Net income increased in 2015 by 7% to $886 million due to higher net revenues and a decrease in operations and maintenance expenses related to tracked costs and costs that are part of base electric and natural gas distribution rates.

In 2015 Eversource's operating cash inflows decreased by 13% to $1.42 billion as the result of changes in working capital due to Department of Energy damages proceeds received from the Yankee Companies of $4.7 million in 2015 (compared to $132 million in 2014).


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.

The company continues to invest heavily in electric transmission projects that maintain the reliability of the region's electric grid. It also planned to invest heavily in natural gas delivery infrastructure, including $213 million in 2015 and nearly $1.3 billion from 2016 through 2019.
