no word on that deal. but in the usa it looks like battery adds .015@kwh—this was from a record low contract priced signed in arizona in May by Tuscon Electric Power.
TEP declined to reveal the exact pricing, but the all-in cost for the solar-plus-storage project is “significantly less than $0.045/kWh over 20 years,” said Carmine Tilghman, senior director for energy supply at TEP. And, at under 3¢s/kWh, he says he believes the solar portion of the PPA is “the lowest price recorded in the U.S.”
