 PSC APPROVES GAS MERGER,
SETS CUSTOMER PROTECTIONS

LINCOLN – The Nebraska Public Service Commission has 
issued an order approving the proposed merger between 
natural gas utilities Black Hills Corp. and NorthWestern 
Energy Group, Inc. The Commission is required under 
state law to ensure such transactions do not harm 
customers and are consistent with the public interest.

With the order, Nebraska becomes the first state to 
approve the proposal. Approval remains pending before 
regulators in Montana and South Dakota, as well as 
federal authorities.

The Commission’s order today follows review of 
testimony, filings and evidence submitted in Docket 
NG-128. The order also approves settlement agreements 
reached between the utilities, the Laborers’ International 
Union of North America (LIUNA) and the Public Advocate 
appointed to represent ratepayers. 

“The Commission undertook a thorough and careful review 
of this request to ensure it serves the public interest,” said 
Commission Chair Tim Schram. “Approval of the merger, 
subject to the terms of the settlement agreements, will 
support continued safe, reliable natural gas service for 
Nebraskans while maintaining responsible regulatory 
oversight and customer protections.”

As part of the approved settlements, the utilities agreed to 
a range of enforceable commitments, including:

  • Rate protections: A moratorium on general base rate 
    increases for NorthWestern Energy in Nebraska until 
    May 1, 2027; and for Black Hills in Nebraska until May 
    1, 2028, with limited exceptions for extraordinary 
    circumstances.
  • Cost protections: A prohibition on recovering merger 
    transaction costs from Nebraska ratepayers and 
    restrictions on seeking recovery of certain transition 
    costs unless customer benefits outweigh those costs.
  • Oversight and reporting: Annual reporting on safety, 
    service quality and merger integration activities to 
    ensure ongoing accountability to regulators and the 
    public.
  • Workforce and contracting provisions: Commitments 
    to fair contracting practices, consideration of Nebraska-
    based labor, and requirements tied to safety standards 
    and compensation for large-scale infrastructure projects.

The Commission found that the agreements represent a 
reasonable resolution to the issues in the case and that the 
proposed merger would not adversely affect the utilities’ 
ability to serve their combined total of approximately 350,000 
customers across Nebraska. Black Hills and NorthWestern 
have indicated that the merger is not expected to result in 
customer-facing changes to day-to-day services such as 
billing, meter reading or emergency response.

The utilities announced the all-stock merger in August 2025. 
It was approved by shareholders of both companies in April 
2026.

The transaction is expected to close in the second half of 
2026, pending remaining governmental approvals.
