The story
On April 16, 2008, a series of avalanches destroyed and damaged transmission towers on the line connecting the Snettisham Hydroelectric Project with Juneau, severing the city's main source of hydroelectric power. AEL&P immediately switched to diesel generators to supply the city's electricity needs. Diesel consumption exceeded 80,000 gallons per day, while electricity costs increased from about 11 cents to 52.5 cents per kilowatt-hour. The resulting increase in electricity costs prompted widespread conservation efforts among Juneau residents and businesses. The transmission line was repaired and hydroelectric service restored after about 45 days.
