Exhibit 99.1

EEI FINANCIAL CONFERENCE November 10 - 12, 2019

Safe Harbor Statement 1 All per - share amounts in this presentation are reported on a diluted basis. The only common equity securities that are publicly traded are common shares of Eversource Energy. The earnings and EPS of each business do not represent a direct legal interest in the assets and liabilities allocat ed to such business, but rather represent a direct interest in Eversource Energy's assets and liabilities as a whole. EPS by business is a non - GAAP (not determined using generall y accepted accounting principles) measure that is calculated by dividing the net income or loss attributable to common shareholders of each business by the wei ght ed average diluted Eversource Energy common shares outstanding for the period. Earnings discussions also include a non - GAAP financial measure referencing 2019 earni ngs and EPS excluding the impairment charge for the Northern Pass transmission (NPT) project. Eversource Energy uses these non - GAAP financial measures to evaluate and provide details of earnings results by business and to more fully compare and explain 2019 results without including the impact of the NPT impairment charge. Management believes the NPT impairment charge is not indi cat ive of Eversource Energy’s ongoing performance. Due to the nature and significance of the impairment charge on net income attributable to common shareholders, man agement believes that the non - GAAP presentation is a more meaningful representation of Eversource Energy’s financial performance and provides additional and use ful information to readers in analyzing historical and future performance of the business. Non - GAAP financial measures should not be considered as alternatives to Ever source Energy’s consolidated net income attributable to common shareholders or EPS determined in accordance with GAAP as indicators of Eversource Energy’s ope rat ing performance. This presentation includes statements concerning Eversource Energy’s expectations, beliefs, plans, objectives, goals, strateg ies , assumptions of future events, future financial performance or growth and other statements that are not historical facts. These statements are “forward - looking state ments” within the meaning of the Private Securities Litigation Reform Act of 1995. Generally, readers can identify these forward - looking statements through the use of w ords or phrases such as “estimate,” “expect,” “anticipate,” “intend,” “plan,” “project,” “believe,” “forecast,” “should,” “could” and other similar expressions. Fo rward - looking statements involve risks and uncertainties that may cause actual results or outcomes to differ materially from those included in the forward - looking statemen ts. Factors that may cause actual results to differ materially from those included in the forward - looking statements include, but are not limited to: cyberattacks or breache s, including those resulting in the compromise of the confidentiality of our proprietary information and the personal information of our customers; acts of war or terrorism , p hysical attacks or grid disturbances that may damage and disrupt our transmission and distribution systems; ability or inability to commence and complete our major strateg ic development projects and opportunities; actions or inaction of local, state and federal regulatory, public policy and taxing bodies; substandard performance of third - pa rty suppliers and service providers; fluctuations in weather patterns, including extreme weather due to climate change; changes in business conditions, which coul d i nclude disruptive technology related to our current or future business model; increased conservation measures of customers and development of alternative energy sources; co ntamination of, or disruption in, our water supplies; changes in economic conditions, including impact on interest rates, tax policies, and customer demand and pay men t ability; changes in levels or timing of capital expenditures; disruptions in the capital markets or other events that make our access to necessary capital more diffi cul t or costly; changes in laws, regulations or regulatory policy, including compliance with environmental laws and regulations; changes in accounting standards and financia l r eporting regulations; actions of rating agencies; and other presently unknown or unforeseen factors. Other risk factors are detailed in Eversource Energy’s reports filed with the Securities and Exchange Commission (SEC) and up dat ed as necessary, and are available on Eversource Energy’s website at www.eversource.com and on the SEC’s website at www.sec.gov. All such factors are difficult to pr edict and contain uncertainties that may materially affect Eversource Energy’s actual results, many of which are beyond our control. You should not place undue relia nce on the forward - looking statements; each speaks only as of the date on which such statement is made, except as required by federal securities laws, and Eversource Ene rgy undertakes no obligation to update any forward - looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events.
