Additional information

Salt River Project has signed a 20-year power purchase agreement with NextEra Energy Resources for a project in Arizona that will combine a solar array with energy storage. The single-axis tracker PV farm will charge the battery for use when the sun is not shining, with Salt River Project likely to evaluate its usefulness in countering periods of peak demand and otherwise optimising the use and consumption of power from solar generation assets.
