Eversource is New England's largest energy delivery company, providing safe, reliable and sustainable electric, gas and water service to 4.4 million customers across Connecticut, Massachusetts and New Hampshire. With nearly 10,000 employees committed to their communities, Eversource traces its roots back to the middle of the 19th century, when numerous regional utility companies first began powering the region. Through decades of strategic mergers and consolidation, these pioneering entities came together to form a unified energy delivery system that today stands as the backbone of New England's power infrastructure.
Formerly known as Northeast Utilities, the company rebranded to Eversource Energy in 2015, marking a new chapter in its mission to deliver safe, reliable energy while advancing clean technologies and environmental sustainability. As a Fortune 500 company trading on the NYSE under the symbol ES, Eversource combines deep historical expertise with forward-thinking innovation, investing billions in smarter, more resilient infrastructure to meet the evolving needs of the 21st century. The company's nearly 10,000 men and women live in the neighborhoods they serve, working to power the possible for New England's homes, businesses and communities.
