Hawaii at a glance
Hawaii is the most expensive electricity market in the United States by a wide margin, and the cause is geographic rather than regulatory: no pipeline or transmission line reaches the islands, so most generation burns imported petroleum priced on world markets. Each island runs its own grid with no mainland backup. Cooling demand is steady year-round, and there is essentially no heating load.
