Grayling Power Plant Upgrades
AVEC with the funding of Denali Commission and Alaska Energy Authority have been investing in various upgrades that will improve plant efficiency enabling future integration of renewable energy. The existing manual single-phase three-in-one panel controls are being replaced with automated switchgear controls, a significant upgrade to the cooling system, and two new electronic gensets are being installed.
Additionally, AVEC and Alaska Native Tribal Health Consortium are working together to upgrade the heat recovery system supplying heat to the water treatment plant in Grayling. The heat recovery system was constructed in 2018. This project replaces the exhaust manifold on the primary Detroit Diesel Series 60 generator engine with a marine manifold with a turbocharger and includes updating the required controls.
