What Unitil does
Unitil Corporation (NYSE: UTL), founded in 1984 and headquartered in Hampton, New Hampshire, is a public utility holding company delivering regulated electricity and natural gas distribution services across Maine, New Hampshire, and Massachusetts. The company serves approximately 110,100 electric customers and 105,000 natural gas customers across state-granted exclusive service territories, with revenue collected through rates set by state Public Utilities Commissions under cost-of-service regulation. Following the 2025 acquisitions of Bangor Natural Gas (January 2025) and Maine Natural Gas ($86M, November 2025), Unitil became the largest natural gas utility in Maine, serving approximately 90% of the state's gas customers. A pending acquisition of Aquarion water entities in New Hampshire for ~$57M signals further vertical expansion into regulated water utility services.
The company's technology backbone centers on Advanced Metering Infrastructure (AMI) deployed across Massachusetts (2025 complete) and New Hampshire (beginning January 2026 in Merrimack County), enabling 15-minute interval data collection, two-way communication, remote service management, and time-based rate structures including Time-of-Use and Electric Vehicle TOU programs. Supporting platforms include an outage management system, GIS mapping technology, a grid intelligence platform integrating distributed energy resources, and a utility-scale battery storage system in Massachusetts serving 1,300+ homes. The MyUnitil customer portal and mobile app (iOS/Android) provide digital self-service for account management, bill payment, energy usage monitoring, and outage reporting. Over 3,600 distributed energy resource interconnections have been successfully integrated. Advanced meters comply with NIST 800-53 cybersecurity guidelines.
Unitil's revenue model is subscription-recurring under regulated cost-of-service frameworks: distribution charges, transmission charges, and supply charges are billed monthly to residential, commercial, and industrial customer classes, with rates varying by jurisdiction. Differentiated products include Massachusetts Heat Pump Rates (seasonal discount Nov–Apr, ~$540 average winter savings), TOU and EV-TOU rates, net metering for customer-owned generation, an EasyCare rental program for water heaters and conversion burners, Energy Navigator personalized recommendations, and a Wholesale Distribution Service enabling storage customers to participate in New England wholesale markets. A $1.2 billion five-year capital investment plan through 2030 targets 6.5%–8.5% annual rate base growth, funded in part by a 1.4M-share public offering completed in August 2025. The company maintains a 42-year consecutive dividend payment streak with a current annualized dividend of $1.90 per share. FY2025 net income reached a record $50.2M, and Q1 2026 revenue grew 27% YoY to $216.9M.
