Related: About this forumHawaii's new reality of solar plus storage: under 10 cents
https://pv-magazine-usa.com/2019/03/28/hawaiis-new-reality-of-solar-plus-storage-under-10-cents/In only a few years, solar paired with energy storage has gone from a niche concept to the new reality of the U.S. power system. And it all really came down to price.
While the 14.5 cents per kilowatt-hour that SolarCity was able to achieve with solar plus storage on Kauai was groundbreaking three and half years ago when it was announced, today Hawaiian regulators set a new threshold for the price that solar projects fully backed by four-hour batteries must beat: 10 cents per kilowatt-hour.
The Hawaiian Public Utilities Commission (HPUC) has approved contracts between the subsidiary utilities of Hawaiian Electric Industries and the developers of six projects, representing a combined capacity of 247 MW of solar, and 998 megawatt-hours of energy storage meaning that the entire capacity of all six projects will be fully backed by four-hour batteries.
The price for each of these contracts was between eight and ten cents per kilowatt-hour. This is cheaper than both gas peaker plants and HEIs current cost of fossil fuel generation, much of which is petroleum-based, which the company put at around 15 cents per kilowatt-hour.

They did. They sure dont seem to be helping us with decentralized generation very much.
They talk up $.10 but is that to the end user or the cost to HECO and they continue to charge us $.28?
(I realize Kauai is independent)
