Regulatory Commission of Alaska: Notice of Utility Tariff Filing (ENSTAR)

What is this notice about?

ENSTAR Natural Gas Company asked the Regulatory Commission of Alaska (RCA) to approve a gas swap deal with Matanuska Electric Association (MEA) and Hilcorp, and to pass the related costs and credits on to customers through its gas cost adjustment (GCA) surcharge. Under the deal, Hilcorp would deliver about 1.2 billion cubic feet of gas to ENSTAR in late 2026, and ENSTAR would return the same amount to MEA by March 31, 2028. The public can comment until 5:00 p.m. on October 29, 2026.

Why was this notice issued?

ENSTAR filed tariff filing TA361-4 with the Regulatory Commission of Alaska asking for approval of a Gas Exchange Agreement and related tariff changes, and the Commission must give public notice of utility tariff filings.

What action is being taken?

The Commission is reviewing ENSTAR's request to approve a Gas Exchange Agreement with MEA and Hilcorp and to pass the associated costs and credits through the gas cost adjustment (GCA) surcharge. ENSTAR would pay Hilcorp $11.75 per thousand cubic feet (Mcf) for the initial gas ($9.00 per Mcf gas value plus a $2.75 per Mcf Hilcorp fee), and gas returned to MEA would be valued at $9.00 per Mcf. The filing also proposes revising Section 708 of ENSTAR's tariff to add gas exchange agreements as a new cost element in the GCA surcharge method. ENSTAR asks for expedited review and an October 30, 2026 effective date. The Commission may approve a rate or classification different from what was proposed.

Who is involved: ENSTAR Natural Gas Company, LLC (applicant); Matanuska Electric Association, Inc. (MEA); Hilcorp Cook Inlet, LLC (Hilcorp); ENSTAR natural gas customers
