New Hampshire Public Utilities Commission

The New Hampshire Public Utilities Commission (NHPUC) is the primary state body responsible for regulating public utilities operating within New Hampshire's borders. It exercises jurisdiction over electric, natural gas, telephone, water, and sewer utilities, setting rates, approving service standards, and adjudicating disputes between utilities and their customers. The Commission's decisions directly affect the cost and reliability of essential services for residential and commercial ratepayers across all 10 of the state's counties.

Definition and scope

The NHPUC operates under authority granted by RSA Title XXXIV, which establishes the Commission's structure, powers, and jurisdiction. The Commission is composed of 3 commissioners appointed by the Governor with the consent of the Executive Council, each serving staggered 6-year terms (RSA 363:1).

Utilities subject to NHPUC jurisdiction include:

  1. Electric distribution companies (e.g., Eversource Energy, Liberty Utilities)
  2. Natural gas distribution companies
  3. Local exchange telephone carriers
  4. Water and sewer utilities operating as public utilities under state law
  5. Competitive electric suppliers requiring registration

Scope limitations and coverage boundaries: The NHPUC's authority is confined to intrastate utility operations. Interstate transmission facilities, wholesale electricity markets, and interstate natural gas pipelines fall under the jurisdiction of the Federal Energy Regulatory Commission (FERC), not the NHPUC. Municipal water and sewer departments that operate as departments of local government — rather than as corporate utilities — are generally not subject to NHPUC rate regulation. Telecommunications services classified under federal deregulatory frameworks may also fall outside Commission jurisdiction. Professionals and researchers working across New Hampshire's broader government landscape can reference the New Hampshire Government Authority for parallel agency coverage.

How it works

The Commission operates through a formal docketed proceeding system. Each regulatory matter — a rate case, a tariff filing, a petition for a franchise certificate — is assigned a docket number and proceeds through defined procedural steps including public notice, evidentiary hearings, and written orders.

Rate-setting process:

  1. A utility files a rate case petition, including a cost-of-service study and proposed rate schedules.
  2. The Commission's staff, the Office of Consumer Advocate (OCA), and intervenors conduct discovery and file testimony.
  3. Evidentiary hearings are held before a presiding officer or the full Commission.
  4. The Commission issues an order establishing just and reasonable rates, applying the standard set out in RSA 378:7.

The Commission also administers the Site Evaluation Committee process (in coordination with other state agencies) for energy facility siting involving generation projects of 30 megawatts or larger (RSA 162-H).

A distinction exists between rate regulation and registration requirements. Traditional investor-owned utilities are subject to full cost-of-service rate regulation. Competitive electric suppliers, by contrast, must register with the Commission but are not subject to rate regulation — they operate under market pricing, and the Commission's oversight focuses on consumer protection disclosures and compliance.

Common scenarios

Formal rate case: An electric distribution company seeks a base rate increase to recover infrastructure investment. The proceeding typically spans 9 to 12 months and results in a Commission order either approving, modifying, or denying the requested rates.

Customer complaint adjudication: A residential ratepayer disputes a service termination or a billing dispute that the utility has not resolved. The Commission's Consumer Affairs staff can investigate informal complaints; unresolved matters may be elevated to a formal docket.

Certificate of public convenience and necessity: A new utility or an entity seeking to expand service territory must obtain a certificate (RSA 374:22) before commencing operations. This applies to water utilities, new gas distribution entrants, and similar providers.

Renewable portfolio standard (RPS) compliance: Under RSA 362-F, electric utilities and competitive suppliers must demonstrate compliance with New Hampshire's renewable energy class requirements. The Commission audits annual compliance filings and may assess administrative fines for deficiencies.

Interconnection disputes: Distributed generation owners — solar installers, small wind operators — may petition the Commission when a utility disputes the terms of grid interconnection.

Decision boundaries

The NHPUC issues three categories of formal decisions:

  1. Orders — binding determinations in docketed proceedings, subject to appeal to the New Hampshire Supreme Court under RSA 541.
  2. Declaratory rulings — interpretive determinations on whether a given entity or activity falls within Commission jurisdiction.
  3. Staff letters and informal guidance — administrative communications that do not carry the force of a formal order.

The Commission does not have jurisdiction over:

Appeals from Commission orders proceed to the New Hampshire Supreme Court, not to the Superior Court. This direct appellate pathway, established under RSA 541, distinguishes utility regulatory review from standard administrative agency appeals, which may pass through the Superior Court first. The New Hampshire Insurance Department and the New Hampshire Banking Department operate analogous single-industry regulatory structures at the state level, though with distinct statutory foundations and no overlap with utility rate jurisdiction.
