Alaska Interconnection

Both grids, though, are managed by the Alaska Systems Coordinating Council (ASCC) as if they were one entity like the other interconnections in North America.

ASCC was formed in 1983 and is an affiliate North American Electric Reliability Corporation (NERC) member.

[2] While both parts of the Alaska Interconnection have no connection to remaining interconnections of North America, all generating units connected to both of its grids generate at a synchronous speed of 60 Hz, the frequency common to North America.

Electricity is also delivered to homes and small businesses in the same manner as in Canada and the contiguous United States with a split-phase 120/240 volt service.

[4] Because the transmission networks in Alaska are isolated from other interconnections in North America, average rates for electricity are $0.18 per kWh – the second highest price in the United States after Hawaii, whose average residential rate is $0.37 per kWh.
