WESTERN MASSACHUSETTS ELECTRIC CO

Western Massachusetts Electric Co., CIK 106170, operates as a regional electric utility rooted in SIC 4911, delivering power distribution and related grid services to residential, commercial, and municipal customers across western Massachusetts and parts of central Connecticut; it maintains a balanced portfolio of transmission maintenance, demand response programs, and localized customer care that together support reliability for mixed-use communities and industrial parks. The company’s work centers on strengthening delivery infrastructure, managing storm response, and collaborating with state regulators to align with decarbonization mandates, while also offering energy efficiency solutions to help large customers manage peaks. As with any utility, it faces material risks from unforeseen storms, supply chain pressure for critical equipment, and evolving rate cases in front of the Massachusetts Department of Public Utilities, plus compliance requirements tied to federal reliability standards and climate laws.
