Alaskans have relied on ENSTAR to serve their homes and businesses with cleaner burning, economical and efficient natural gas for over 60 years. ENSTAR Natural Gas Company, headquartered in Anchorage, Alaska, is a regulated public utility that delivers natural gas to more than 150,000 residential and commercial customers in 26 communities in Southcentral Alaska, a customer base that represents approximately 60% of the state’s population.

Cook Inlet Natural Gas Storage Alaska (CINGSA) is Alaska’s first commercial natural gas storage facility. It was constructed to address Southcentral Alaska’s peak winter demand for natural gas delivery. CINGSA has a storage capacity of 11 billion cubic feet. Five horizontally drilled wells allow up to 150 million cubic feet of gas per day to be injected or withdrawn from the storage reservoir.
