The Folsom-based California Independent System Operator, which operates the state's wholesale electricity transmission grid, said today that wind power turbines on the grid set a new record of 4,196 megawatts on Sunday.

The record came at 6:44 p.m. That mark came on the heels of Friday's passing of the 4,000-megawatt threshold.

Previously, the ISO's all-time record peak output for wind energy was 3,944 megawatts on March 3.

"With these impressive wind-production levels, California is well positioned to meet the 33 percent by 2020 green power goal," said ISO President and CEO Steve Berberich. "Our control center operators are tracking a steady increase in renewable energy ... "

Currently, ISO said there is a total of 5,899 megawatts of wind plant capacity installed within the California grid.

California is the nation's second largest producer of wind power, trailing only Texas.

ISO said that Texas, which has a current wind-generation peak capacity of 10,407 megawatts, reached a record peak of 9,481 megawatts on February 9.
