I agree Nextera is a good suitor, among the large corporate utilities to serve HI. The dynamic might change, however, as any realistic all-renewables, by 2045, mandate will require aggressive phase-ins. That will, in turn, limit the island's ability to cost out natural gas as a replacement for fuel oil (infrastructure$$). I thought they were even considering an LNG import facility? A higher Renewable Portfolio Standard (RPS) may be the silver lining, but the aforementioned high diesel generator costs could be around until they get there.
If the rest of the United States could capitalize on the difference between 12 and 35 cents /kwh, we could finance Elon's "blue square" I bet. Hmmm, 4,000TWH (.23/kwh) = $920 billion per year. You could probably buy that "farm" in three, if you hadn't politically "bought the farm" much sooner.
