North Dakota Public Service Commission: Utilities Regulation

The North Dakota Public Service Commission (PSC) holds constitutional authority over public utilities operating within the state, including electric, natural gas, telephone, and pipeline services. The Commission's regulatory functions determine how rates are set, how service territory disputes are resolved, and which entities must obtain certificates before operating. This page covers the Commission's jurisdictional scope, its procedural mechanisms, the categories of decisions it issues, and the boundaries separating PSC authority from other state and federal regulatory bodies.

Definition and scope

The North Dakota Public Service Commission is a 3-member elected body established under Article V, Section 14 of the North Dakota Constitution. Commissioners serve staggered 6-year terms and exercise regulatory authority granted under North Dakota Century Code (NDCC) Title 49, which governs public utilities and carriers.

The PSC's primary subject-matter jurisdiction covers:

  1. Electric utilities — investor-owned electric providers operating under franchise or certificate of public convenience and necessity
  2. Natural gas distribution companies — local distribution companies (LDCs) supplying gas to residential and commercial customers
  3. Telephone utilities — incumbent local exchange carriers (ILECs) and certain competitive carriers as defined under NDCC § 49-21
  4. Pipeline safety — intrastate gas and hazardous liquid pipeline operators subject to federal pipeline safety statutes adopted by reference
  5. Grain buyers and warehousemen — licensing and bonding functions separate from utility rate regulation
  6. Underground damage prevention — administration of the North Dakota One-Call notification system

Rate regulation authority applies specifically to investor-owned utilities. Rural electric cooperatives operating under the Rural Electrification Act framework are not subject to PSC rate oversight; their rates are governed by cooperative member-board processes. The North Dakota Industrial Commission retains separate jurisdiction over oil and gas extraction, a distinction addressed further under Decision Boundaries below.

Scope limitation: PSC jurisdiction is bounded by state lines. Wholesale electricity transactions conducted across state lines fall under the Federal Energy Regulatory Commission (FERC) pursuant to the Federal Power Act (16 U.S.C. § 824). Interstate natural gas pipelines and storage facilities are regulated by FERC, not the PSC. Telecommunications services classified as information services by the Federal Communications Commission (FCC) are also outside PSC rate jurisdiction.

How it works

The PSC conducts formal contested case proceedings, informal complaint resolution, and administrative licensing actions. Formal proceedings follow the North Dakota Administrative Agencies Practice Act (NDCC Chapter 28-32), which requires notice, opportunity for hearing, and written findings.

Rate case procedure:
A utility files a rate application with supporting cost-of-service studies, proposed tariff sheets, and financial data. The PSC issues a procedural schedule establishing discovery deadlines, intervention cutoff dates, and a hearing date. Intervenors — which may include the North Dakota Attorney General's Consumer Protection Division, industrial customers, or municipal governments — may submit testimony and cross-examine witnesses. The Commission issues a final order setting the authorized rate of return and approving, modifying, or rejecting proposed tariff schedules.

Under NDCC § 49-05-10, investor-owned utilities may implement interim rate increases pending final order, subject to refund, where the Commission has not acted within 75 days of a complete application filing.

Certificate of Public Convenience and Necessity (CPCN):
Any entity seeking to construct a high-voltage transmission line (115 kV or above), a large wind or solar generation facility, or a major natural gas pipeline within North Dakota must obtain a siting permit or CPCN from the PSC before construction commences. The threshold for large energy conversion facilities requiring a permit is a nameplate capacity of 50 megawatts or greater (NDCC § 49-22-01).

Common scenarios

Residential utility complaint: A residential customer disputing a billing error or disconnection notice may file an informal complaint with the PSC. Commission staff conducts an investigation and facilitates resolution between the customer and utility. If informal resolution fails, the customer may request a formal hearing.

Transmission line siting: A developer proposing a 230 kV transmission corridor must submit an application identifying the route, environmental review documentation, and evidence of need. The PSC holds public hearings in affected counties — for example, a project crossing Burleigh County and Morton County would require public sessions in each county before a siting decision is issued.

Telecommunications service territory: When 2 carriers dispute the boundaries of a service area, the PSC adjudicates the boundary under its authority over telephone utility certificates, applying criteria that weigh existing infrastructure, customer impact, and competitive market conditions.

Pipeline safety inspection: PSC staff conducts periodic safety inspections of intrastate natural gas distribution systems. Violations of 49 C.F.R. Parts 191–195, as adopted by state rule, may result in civil penalty orders issued by the Commission.

Decision boundaries

The PSC's authority ends at 3 identifiable jurisdictional lines:

PSC vs. FERC: Wholesale power sales, interstate transmission rates, and hydroelectric licensing are FERC-exclusive. The PSC may not regulate the rates a utility charges for power sold into the MISO (Midcontinent Independent System Operator) wholesale market.

PSC vs. North Dakota Industrial Commission: Oil and gas production, including saltwater disposal wells, compressor stations serving production operations, and gas gathering upstream of the custody transfer point, falls under the North Dakota Industrial Commission. The PSC takes jurisdiction over gas distribution downstream of the city gate or custody transfer meter.

PSC vs. municipal franchise authority: Municipalities retain authority to grant or withhold local franchise rights to utilities operating within city limits, though the PSC retains rate jurisdiction over those same utilities regardless of franchise status.
