Healy Power Station Uninterrupted by Alaska Earthquake

Golden Valley Electric did not experience any power outages due to this morning’s earthquake in Anchorage. At the time of the earthquake, our load was approximately 165 MW with 30 MW coming over the Intertie. When the Intertie tripped off-line due to the earthquake, GVEA’s Battery Energy Storage System (BESS) and GVEA’s North Pole plants picked up this load.

Today, Matanuska Electric Assn. (MEA) requested GVEA’s assistance in patrolling the Intertie by air. GVEA sent approx. 4 megawatts of power south into MEA’s territory until they were able to bring some of their substations back on-line. GVEA inspected all of our generation facilities to ensure there was no damage due to the earthquake.

GVEA purchases fuel for our Fairbanks and North Pole power plants from the Petro Star Refinery. This morning, because it was unknown when the Trans-Alaska Pipeline and the Petro Star Refinery would be back on-line, GVEA coordinated fuel delivery from Valdez over the Richardson Hwy, to ensure an adequate fuel supply was available should it be needed. At this time, it is our understanding that both of these facilities will be back on-line this evening.

While the Intertie was off-line today, GVEA ran one North Pole turbine in order to control frequency on our system. Now that we are reconnected to the Intertie, the North Pole turbine has been taken off-line, and we continue to serve our members in the Interior by power generated from our Healy & North Pole Power Stations.
