Ketchikan Public Utilities (KPU) in Alaska has switched off its diesel generators and returned to hydroelectric power after a dry summer. The area usually receives around 19 inches of rain in October, but this year saw just 11 inches, with most of it falling in the second half of the month. KPU's hydro-producing lakes had hit the low end of their target elevation, but the recent rain has allowed the utility to switch back to hydroelectric power. However, the area remains in drought and KPU's diesel generators may need to be switched back on if lake levels do not rise.
