Customers

Unitil serves regulated end users rather than selling into competitive wholesale markets.

The company also serves affiliated utilities through centralized service arrangements and provides pipeline access to its gas distribution businesses.

Residential customers

Households buying electric and/or gas delivery for everyday usage under regulated rates.

Commercial customers

Businesses, offices, and retail users that need reliable local utility service.

Industrial and municipal customers

Larger users that require dependable distribution infrastructure and tariff-based service.

Affiliated utility companies

Subsidiaries that receive centralized administrative, technical, and energy management services.

Strategy

Unitil’s strategy is centered on operating regulated local utility networks and earning returns through approved rate structures. The company also uses centralized service subsidiaries and pipeline infrastructure to support its distribution businesses and maintain a regional operating platform. Its business model depends on disciplined capital investment, regulatory relationships, and reliable service delivery across its franchise territories.

Geography

Unitil’s operations are concentrated in the northeastern United States, primarily New Hampshire, Massachusetts, and Maine. Its utility footprint is local and regulated, with service territories centered around the seacoast and capital regions of New Hampshire, north central Massachusetts, and southern and central Maine. Granite State’s pipeline assets are primarily located in Maine and New Hampshire, reinforcing the company’s regional operating profile.

Risks

Unitil’s business is exposed to regulatory, operational, and infrastructure risks typical of a local utility. Because earnings depend on approved rates and recoverable capital investment, changes in regulation, supply availability, or allowed returns can affect results. The company also faces physical, cyber, weather, and financing risks tied to operating electric and gas networks with significant long-lived assets.
