- Business
- NSTAR Electric Company, doing business as Eversource Energy service company for electric operations, engages in the regulated transmission and distribution of electricity to residential, commercial, and industrial customers primarily in eastern and central Massachusetts, including the Boston metropolitan area; it operates through electric distribution and electric transmission segments, delivering power coordinated by ISO New England without owning generation facilities following post-deregulation divestitures such as the 2002 sale of its Seabrook Station nuclear interest. The company provides core services encompassing retail electricity delivery to over one million customers across 81 communities; high-voltage transmission infrastructure; smart grid technologies for self-healing power restoration and outage minimization; district energy production of electricity, steam, and chilled water via subsidiaries like Medical Area Total Energy Plant, LLC in Boston's Longwood Medical Area; and support for renewable integration including wind power contracts, electric vehicle infrastructure with EV supply equipment rebates and make-ready incentives, networked geothermal pilots, solar, offshore wind, and battery storage programs. Founded in 1999 through the merger of Boston Edison Company, Cambridge Electric Light Company, Commonwealth Electric Company, and NSTAR Gas Company (formerly Commonwealth Gas and Cambridge Gas), NSTAR Electric is headquartered in Westwood, Massachusetts, and operates solely within Massachusetts as a wholly-owned subsidiary of Eversource Energy, formed after its 2012 acquisition by Northeast Utilities (rebranded Eversource in 2015). Recent developments include a $56 million electric rate increase approved effective January 2025 to support infrastructure investments; ongoing Phase II electric vehicle program modifications such as enhanced rebates for direct current fast chargers, heat pump expansions, and third-party funding stacking without deductions; declaration of preferred dividends in December 2024 and ongoing debt securities underwriting agreements in 2025 with banks including Goldman Sachs, Mizuho, and J.P. Morgan; and capital expenditure emphasis on electric distribution (43% allocation) and transmission (28%) as part of Eversource's modernization efforts amid regulatory approvals for performance-based ratemaking.
