Alaska Electric Light and Power is expecting a cost of power adjustment credit for its customers starting as early as October 1.
AEL&P spokesperson Debbie Ferreira said customers could see a $0.007963 credit per kilowatt-hour used. A household that uses 1,000 Kwh a month would save $7.96 on its monthly bill. The cost reduction continues through December.
“Most often our COPA is a credit,” Ferreira said. “If it isn’t a credit it is typically because a lot of [diesel] fuel was used.”
The utility kept maintenance costs and diesel fuel use below what was expected, Ferreira. Also, plenty of rain allowed sale of the extra power generated at the utility’s hydroelectric facilities to Juneau’s interruptible and duel fuel customers.
Princess Cruises and Greens Creek mine can buy surplus electricity to offset onsite generation. While the University of Alaska Southeast and the federal building have both electric and oil boilers.
“When we have surplus energy, we sell,” Ferreira said, “but when we need that energy, we can shut it off immediately.”
This is not an option for communities like Ketchikan that don’t have interruptible customers.
“So when it pours rain like this they have to spill it,” Ferreira said.
AEL&P files a COPA request with the Regulatory Commission of Alaska every quarter.
AEL&P customers saw an average COPA increase of $3.75 on their first three monthly bills of 2012 due to diesel generator use during an unplanned power outage in Nov. 2011.
