Contents

The landscape of natural gas in Anchorage, Alaska, is undergoing significant changes, particularly as of late 2025, directly impacting the wallets and energy security of Southcentral Alaska residents. As the primary natural gas distributor in the region, ENSTAR Natural Gas Company is currently navigating complex regulatory challenges, critical infrastructure upgrades, and an ongoing long-term gas supply concern from the vital Cook Inlet basin. These factors are converging to create a period of uncertainty for over 150,000 residential and commercial customers.

The most pressing issue for consumers is the proposed rate increase, which is currently under review by the state’s Regulatory Commission of Alaska (RCA). This article breaks down the most recent, essential updates on ENSTAR’s operations, its corporate structure, and the future of the natural gas market in Alaska’s largest city.

ENSTAR Natural Gas Company: Corporate Profile and Key Entities

ENSTAR Natural Gas Company is a regulated public utility that serves the vast majority of Southcentral Alaska, including Anchorage, the Kenai Peninsula, and other surrounding areas. Understanding the corporate structure and the key players is essential to grasping the forces shaping the region's energy future.

  • Utility Name: ENSTAR Natural Gas Company, LLC
  • Headquarters: Anchorage, Alaska
  • Service Area: Southcentral Alaska (over 150,000 customers)
  • Parent Company: TriSummit Utilities Inc. (A Canadian-based energy infrastructure company)
  • Ownership: TriSummit Utilities is owned by Canadian pension funds.
  • Previous Ownership: Acquired by TriSummit from AltaGas, which previously acquired SEMCO Energy Inc.
  • Affiliates: Alaska Pipeline Company (APC)
  • Key Management: John Sims (President)
  • Regulator: Regulatory Commission of Alaska (RCA)

This organizational structure means that major decisions regarding utility operations, investment in energy infrastructure assets, and rate filings are ultimately influenced by the governance of TriSummit Utilities and subject to the strict oversight of the RCA.

The 2025 Rate Hike and Regulatory Scrutiny

The most significant and immediate news concerning ENSTAR in late 2025 revolves around two separate but related filings to increase customer costs, both of which are under intense scrutiny by the Regulatory Commission of Alaska (RCA).

1. General Rate Case Filing (May 2025)

On May 2, 2025, ENSTAR filed a comprehensive rate case with the RCA. The utility is requesting a general increase in customer rates to cover rising operational costs, maintenance, and capital investments.

  • Requested Increase: An increase of 5.77% per year for customers.
  • Estimated Customer Impact: If approved, the average customer's gas bill is projected to increase by approximately $8.95 a month.
  • Justification: The request is driven by the need to recover costs associated with maintaining and upgrading the aging natural gas distribution system, ensuring system reliability, and general operating expenses.

2. Gas Cost Adjustment (GCA) Hike (July 2025)

In addition to the general rate case, ENSTAR filed Tariff Revision TA355-4 on May 15, 2025. This filing specifically addresses the Gas Cost Adjustment (GCA), which is a mechanism utilities use to pass the fluctuating cost of acquiring natural gas directly to consumers without a profit markup.

  • Proposed GCA Change: Seeking to raise the GCA from $9.0716 to $10.1091 per thousand cubic feet (Mcf).
  • Effective Date: The proposed increase is slated to take effect on July 1, 2025.
  • RCA Probe: The RCA has initiated a probe into this increase, particularly amid concerns over the rising cost of supply and the potential for subsidization fears, highlighting the sensitivity of natural gas pricing in the Anchorage market.

The combination of a general rate case and a GCA hike means Anchorage customers are facing a double impact on their monthly utility bills, making the RCA's final decision a critical point of interest for the entire Southcentral Alaska region.

Addressing the Cook Inlet Gas Supply Challenge

The long-term reliability of natural gas in Anchorage is inextricably linked to the production levels in the Cook Inlet Basin. This local supply is the lifeblood of Southcentral Alaska's heating and electricity generation, but it has faced persistent concerns about depletion and future availability.

The 2025 Supply Update

On January 15, 2025, ENSTAR President John Sims provided a crucial Cook Inlet gas supply update to the Regulatory Commission of Alaska. This presentation highlighted the ongoing efforts to secure a stable, long-term supply, especially given that Hilcorp, the largest Cook Inlet natural gas producer, had previously announced uncertainty about producing gas beyond its existing contracts.

To mitigate the supply risk and ensure future energy security, ENSTAR has been actively pursuing strategic partnerships:

  • Glenfarne Energy Transition: ENSTAR is working with Glenfarne Energy Transition, a global developer and manager of energy infrastructure assets, to create a more robust supply structure.
  • Gas Storage Solutions: Efforts are underway to improve gas storage capabilities, including a subsidiary of Houston-based Hilcorp Energy Co. applying to operate a new gas storage facility in the Cook Inlet Basin to shore up winter supply.

The necessity to resurrect in-state gas development and secure a longer-term supply remains a central theme for ENSTAR and the entire Alaskan energy sector, as the current production levels near an inflection point.

Infrastructure and Community Investment in 2025

Beyond the regulatory and supply issues, ENSTAR is heavily focused on critical infrastructure projects to maintain the safety and reliability of its distribution network, much of which is decades old.

The Kenai Gas Line Replacement Project

A major focus for 2025 is the continuation of the Kenai Gas Line Replacement Project. This essential work involves replacing aging natural gas pipelines that are approaching 70 years of service.

  • Project Goal: To replace old pipelines that are highly susceptible to leaks and damage from the unique challenges of the Alaskan environment, including earthquakes and the constant freezing/thawing of the ground.
  • Safety and Reliability: These replacements are vital for ensuring the continued safe and reliable delivery of natural gas to customers across the region.

In addition to this large-scale work, the utility is also involved in various smaller summer field activity projects across its service territory, including the Kenai Peninsula, to maintain and upgrade its extensive network of pipes, meters, and valves.

Community Support and Customer Service

In a demonstration of community commitment, ENSTAR Natural Gas Company donated $50,000 to the United Way of Anchorage in 2025 to help Southcentral Alaskans who are struggling with energy costs. This charitable effort comes as the utility faces scrutiny over its customer service reputation.

While ENSTAR provides contact information for its Anchorage Administrative Office and customer support, online reviews and its Better Business Bureau (BBB) profile indicate ongoing customer complaints regarding billing errors, service practices, and line locates. Addressing these customer service challenges remains a key area for the company as it seeks to implement significant rate changes.

What Anchorage Customers Need to Know Now

For Anchorage residents, the current environment demands vigilance regarding energy costs and consumption. The proposed 5.77% rate case and the Gas Cost Adjustment increase are not yet final but represent a significant potential rise in heating expenses. Customers should monitor the Regulatory Commission of Alaska’s proceedings for updates on Tariff Revision TA355-4 and the general rate case to understand the final approved rates.

The long-term outlook is tied to the success of securing new Cook Inlet gas supply and the timely completion of crucial infrastructure projects like the Kenai Gas Line Replacement. ENSTAR’s partnership with Glenfarne Energy Transition and the efforts of producers like Hilcorp are central to maintaining the energy stability that Southcentral Alaska relies on for its harsh winters. In the immediate future, managing energy consumption and staying informed about the RCA’s regulatory decisions will be the best strategy for Anchorage natural gas users.
