ENSTAR Natural Gas Company

What ENSTAR Natural Gas Company does

ENSTAR Natural Gas Company is a regulated public utility and the largest natural gas distributor in Southcentral Alaska, headquartered in Anchorage at 5151 Fairbanks Street. Founded in 1961 and operating as a wholly-owned subsidiary of Canadian parent TriSummit Utilities, ENSTAR delivers natural gas to over 150,000 residential, commercial, and industrial customers across more than 25 communities, representing approximately 57% of Alaska's population. The company's core business is regulated gas distribution under tariffs approved by the Regulatory Commission of Alaska (RCA), with revenue generated primarily through monthly subscription billing for gas delivery to its defined service territory.

The company's technology stack centers on physical distribution infrastructure — pipelines, meters, service lines, and a partial ownership stake in the expanded Cook Inlet Natural Gas Storage Alaska (CINGSA) facility in Kenai — supplemented by a customer-facing digital layer. The MyENSTAR online portal (managed by Smart Energy Water, Inc.) and a native mobile application provide 24/7 account management, while ACI Payments Inc. processes bill payment transactions. ENSTAR publishes rate schedules, regulatory filings, and tariff information publicly and engages customers through a multi-channel presence including social media and community programs in Alaska.

ENSTAR's strategic agenda is dominated by long-term supply security. Following Hilcorp's 2022 announcement that it could not produce gas beyond existing contracts expiring in 2033, ENSTAR has pursued a multi-pronged supply strategy: a $67 million CINGSA storage expansion (with CIRI and Northern Natural), a five-year supply agreement with Furie Operating Alaska starting in 2026, an exclusivity agreement with Glenfarne Energy Transition to develop the Cook Inlet Gateway LNG import terminal (with a 30-year supply LOI), a non-binding LOI with Donlin Gold Mine for in-state industrial gas sales, and Berkeley Research Group-led assessments of North Slope, Interior, and LNG alternatives. The company operates three regional offices (Anchorage, Mat-Su Valley, Kenai Peninsula) with a workforce in the 101–250 range and no public financial disclosure.

Partnerships

Eight partnerships are on record, tiered core and minor.

• Glenfarne Energy TransitioncoreStrategic or Co-development Partner · 6 January 2025ENSTAR has entered into an exclusivity agreement with Glenfarne Energy Transition to evaluate and develop a Cook Inlet Gateway LNG import terminal on the Kenai Peninsula. This partnership is critical for securing long-term LNG supply as a bridge solution to address declining Cook Inlet gas production. ENSTAR also has a non-binding letter of intent with Glenfarne for a 30-year domestic gas supply agreement.
• Furie Operating AlaskacoreStrategic or Co-development PartnerENSTAR signed a five-year supply agreement with Furie Operating Alaska to bolster local gas supply starting in 2026. This new gas contract, submitted to the Regulatory Commission of Alaska for approval, represents new gas coming onto the ENSTAR system.
• CIRI (Cook Inlet Region Inc.)coreStrategic or Co-development PartnerENSTAR partnered with CIRI and Northern Natural to invest $67 million to expand the Cook Inlet Natural Gas Storage Alaska (CINGSA) facility in Kenai. This facility, built in 2012 to allow utilities to store gas during summer months for withdrawal during high demand periods, received additional wells and capacity expansion of 2 BCF.
• Northern NaturalcoreStrategic or Co-development PartnerENSTAR partnered with CIRI and Northern Natural to invest $67 million to expand the Cook Inlet Natural Gas Storage Alaska (CINGSA) facility in Kenai, increasing capacity by 2 BCF.
• Berkeley Research GroupminorImplementation/ SI/ Consulting PartnerENSTAR hired Berkeley Research Group following Hilcorp's 2022 announcement to evaluate gas supply options. BRG conducted a Phase I Cook Inlet Gas Supply Assessment in collaboration with Railbelt utilities to identify and implement alternatives to replace declining Cook Inlet gas, including North Slope gas, Interior gas, and LNG import solutions.
• Chugach ElectricminorStrategic or Co-development PartnerENSTAR and Chugang Electric, two of Alaska's largest utilities, have submitted filings to the Regulatory Commission of Alaska making the case for their respective preferred LNG import projects as Cook Inlet gas production declines. ENSTAR backs Glenfarne's Cook Inlet Gateway project while Chugach supports a competing project by Harvest Midstream. The RCA is investigating whether building both facilities would be duplicative.
• Donlin Gold MineminorStrategic or Co-development PartnerENSTAR has signed a non-binding letter of intent with Donlin Gold Mine for in-state gas sales, representing a potential long-term gas customer in Alaska.
• TriSummit UtilitiescoreOthersENSTAR is a TriSummit Utilities company. TriSummit Utilities is a Canadian corporation that is ENSTAR's ultimate parent company. ENSTAR's principal place of business is at 5151 Fairbanks Street, Anchorage, AK 99503.

Direct peers

• Chugach Electric Association: Alaska's largest electric utility, also serving the Railbelt region. Directly comparable as a fellow Alaska regulated utility; competing with ENSTAR on the proposed LNG import solution (backing Harvest Midstream's project instead of Glenfarne). Shares the same Cook Inlet supply dynamics and RCA regulatory environment.
• ONE Gas, Inc. Publicly traded pure-play natural gas LDC serving ~2.3 million customers across Oklahoma, Kansas, and Texas. Directly comparable as a regulated local distribution company with similar rate-base growth and tariff-driven revenue model; useful benchmark for ENSTAR's regulatory economics.
• Spire Inc. Natural gas LDC holding company serving ~1.7 million customers across Missouri, Alabama, and Mississippi, with midstream and marketing segments. Directly comparable on regulated distribution operations and gas supply procurement.
• Northwest Natural Holding Company: Pacific Northwest natural gas LDC serving ~2 million customers in Oregon and Washington. Directly comparable as a regulated gas utility with diversified customer mix and emphasis on renewable natural gas and long-term supply planning.
• Southwest Gas Holdings: Natural gas LDC serving ~2 million customers across Arizona, Nevada, and California. Comparable regulated distribution utility with similar geographic-concentration dynamics and rate-case-driven growth.
• New Jersey Resources Corporation: Natural gas LDC serving ~550,000 customers in New Jersey plus clean energy ventures and storage/midstream. Comparable as a regulated LDC with portfolio diversification beyond distribution.
• Chesapeake Utilities Corporation: Multi-state regulated natural gas distribution utility (~230K customers across Florida, Delaware, Maryland, Pennsylvania, Ohio) plus transmission and propane. Comparable as a smaller-scale regulated LDC with growth via organic expansion and tuck-in acquisitions.
• SEMCO Energy Gas Company: Michigan-based regulated natural gas LDC serving ~300,000 customers across Michigan. Comparable as a mid-size regulated gas utility operating under state public service commission oversight with similar rate-base recovery model.

Others

• Hilcorp Energy Alaska: Cook Inlet's largest natural gas producer and ENSTAR's incumbent supplier through contracts expiring 2033. Highly relevant as the upstream counterparty whose decline drives ENSTAR's supply strategy; not a peer in a competitive sense but the most important supply-side relationship.
• Glenfarne Energy Transition: Developer of the Cook Inlet Gateway LNG import terminal project on the Kenai Peninsula under exclusivity with ENSTAR. Highly relevant as ENSTAR's core LNG import partner; an enabling/development partner rather than a peer but critical to ENSTAR's long-term supply thesis.
