ENSTAR’s service area spans nearly 5,000 square kilometers and includes 711 kilometers of high-pressure transmission lines and 5,000 kilometers of distribution pipelines. Included in the transmission kilometrage are two subsea pipelines that deliver gas from the Kenai Gas Fields to Anchorage and beyond. ENSTAR delivers gas to its customers and also transports gas on behalf of area electric utilities, which use natural gas to generate more than 80% of electricity.
In total, ENSTAR delivers approximately 60 billion cubic feet (Bcf) of natural gas each year, with 33 Bcf of that gas going to ENSTAR customers.
Average winter daily demand for ENSTAR’s system is around 230 million cubic feet per day (MMcf/d).
