Most of Sitka lost power for about a half-hour Wednesday afternoon (4-29-15), but the new equipment at the Blue Lake project was not to blame. A gate at the Green Lake No. 2 turbine was the culprit.
Due to a fault in the Blue Lake switchyard, all of Sitka lost power this afternoon at approximately 1:40 PM. Powerhouse technicians are currently re-energizing the grid, and estimate that electric service will be restored throughout the community by 2:30. Once power is back up, they’ll investigate the cause of the outage.
Sitka's environmental superintendent Mark Buggins says Sitka's water smells more strongly of chlorine -- because there's more chlorine in it. The temporary filtration plant at Indian River has much different disinfection requirements than Blue Lake, including higher chlorine. Disinfection standards are higher now than when the Indian River was last used as Sitka's water supply in 1984. The city should go back on Blue Lake water in mid-October.
After 53 years of continuous service, the turbines at Sitka’s Blue Lake Hydro plant are quiet. Walt Dangel, one of the original powerhouse operators at Blue Lake, threw the switches turning off the plant in a small decommissioning ceremony Monday morning (8-18-14). Dangel was assisted by Frank Rogers, Sitka’s senior plant operator. The two old turbines produce a combined 6 megawatts of power. They’re being replaced by three new turbines that will produce 16 megawatts.
City officials updated the Chamber of Commerce on the Blue Lake hydro project this week. Engineer Dean Orbison reminded the Chamber that Sitka has continued to rely on Blue Lake for drinking water through the construction. But for about two months this fall, the city will have to switch to Indian River.
The Sitka Assembly approved a contract Tuesday night with a California company that hopes to bottle water from the Blue Lake reservoir. The contract gives the company, I Water, the right to buy up to 200-million gallons of city water a year. But I Water must start exporting water soon -- or risk losing its water rights.
