California hits solar power record: Meets nearly half demand
California ISO reported on its Twitter feed that the all-time peak percentage of demand served by solar hit 49.95 percent at 12:58 p.m. that day. The previous record was 47.2 percent on May 14, 2017.
The ISO manages 80 percent of the power grid across California and Nevada, according to reports. California ISO’s home state has added about 2,000 MW of solar capacity annually for the past three years.
Overall, California has more than 17,000 MW of installed capacity. The state’s Renewables Portfolio Standard calls for clean energy to account for 33 percent of retail electricity sales by 2020.
In February 2018, one of California’s big three utilities, Pacific Gas & Electric, announced it had reached California’s 2020 renewable energy goal three years ahead of schedule, and now delivers nearly 80 percent of its electricity from greenhouse-gas free resources.
