HPUC approved six solar and storage contracts of cumulative 247 MW / 998 MWh

According to the Institute for Energy Economics and Financial Analysis (IEEFA) in Cleveland, USA, 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 MWh of energy storage. 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 HEI’s current cost of fossil fuel generation, much of which is petroleum-based, which the company put at around 15 cents per kilowatt-hour,« says IEEFA.
