High on the list of notable projects of the year is Tucson Electric Power’s (TEP) solar plus storage facility. The project is being built by NextEra Energy and features a 100 MW solar array and a 30 MW, 120 MWh energy storage system. Its most notable feature, however, is its power purchase agreement.

TEP reported that the all-in cost for the solar-plus-storage project was “significantly less than $0.045/kWh over 20 years.” TEP said the solar portion of the project, at under 3¢/kWh, was “the lowest price recorded in the U.S.” That puts the remaining storage portion of the project at about 1.5¢/kWh.
