Wholesale energy prices dip below zero because of California’s solar power


Solar power in CaliforniaSolar power shines bright in California, and wholesale energy prices prove it. Last winter and early spring’s dependence on solar drove wholesale energy prices to negative prices, according to the U.S. Energy Information Administration.

Solar power in the California Independent System Operator accounted for nearly 40% of net grid power for three hours on March 11, 2017, the administration reports —a major first.

These figures don’t translate for the consumer into retail prices, which are based on averages. But the move will likely cause energy companies to pay more attention to green energy options.
