Power Generation

STG has constructed over twenty diesel power generation facilities (power plants) throughout Western Alaska for both Alaska Energy Authority and Alaska Village Electric Cooperative.  These power plants, which range in size from 100 to 1,500 kilowatts, generally consist of modular units with either gravel pad or pile foundations. In connection with these services, STG has also completed several power distribution projects in Western Alaska for Alaska Energy Authority, Alaska Village Electric Cooperative and United Utilities, Inc. The projects have consisted of both direct bury poles and poles installed on pile foundations. Terrain has varied from across tundra to mountainous steep slopes.  Completed distribution lines have ranged in length from short, village-based upgrades to longer village-to-village intertie lines.  Particularly in rural Alaska, STG intertie projects are generally completed in the winter months to minimize environmental impacts, due to the seasonal ability to mobilize heavy equipment across frozen ground.

“STG has been responsive and innovative to our schedules and budgets. We can count on them to get the job done right.”

Featured Project: Kasigluk Rural Power System Upgrade

In Kasigluk, STG once again demonstrated its abilities to execute complex, multi-faceted projects while completing an energy system overhaul for Alaska Village Electric Cooperative.  This project entailed transferring primary power generation from Nunapitchuk to Akula Heights while maintaining power generation to these two villages and also maintaining power to Old Kasigluk.  As part of this project, STG constructed a new bulk fuel retail facility for the communities of Akula Heights and Old Kasigluk along with a new bulk fuel storage facility, totaling over 600,000 gallons of storage capacity in all.  This project also included the construction of a power distribution system to the three aforementioned villages, the installation of a new diesel generation plant, the erection of three 100 kW wind turbines, the installation of a heat recovery system, upgrades to the school district’s bulk fuel facilities, and the installation of a standby generator in Nunapitchuk.
