On May 19, 2016, a small fire was reported when misaligned mirrors reflected sunlight into a level of Unit 3 tower not designed to collect power, requiring the tower to shut down for repairs. As another of the three power-generating units was already offline for scheduled maintenance, the plant was left with only one third of its installation functional. Unit 3 resumed operation on June 8, 2016. All three units were back in operation by June 20, 2016. Solar thermal electricity production in California peaked at 703 MW on that day, up from 452 MW on June 7 when two units were offline.
