Repairs on the Snettisham power line sailed a few more days ahead of schedule last week.
Alaska Electric Light & Power Co. spokesman Scott Willis said that without any major holdups, Juneau could have its hydroelectric power back online by the beginning to middle of this week.
Previously, Willis had estimated June 8.
"Things have gone really smoothly out there," he said.
The unusually long stretch of good weather helped, Willis said. "They've been able to work some very long days."
Finishing early affects local electric rates, which incorporate the cost of running the city on diesel. Residents are now paying 54 cents per kilowatt-hour.
Last week, Willis estimated the rate issued June 16 would be 18 cents per kWh, but the estimate will be lower if the project finishes early. In an ordinary year the summer rate is about 8 cents.
