Batteries for Energy Storage: New Developments Promise Grid Flexibility and Stability

The issue for power plants is flexibility. "Large amounts of wind energy are being reliably and cost-effectively integrated onto the power system today," said Denise Bode, CEO of the American Wind Energy Association (AWEA) , who added "Energy storage can be a valuable resource for the power system in maximising the efficient use of this resource, and add flexibility for electric utilities." The Electric Reliability Council of Texas Inc. (ERCOT) faced the renewable power industry's most critical issue in February 2008. With a huge wind portfolio in the state the wind died down, and ERCOT declared emergency conditions after a 1200-MW drop in production. The three-hour shortfall, accompanied by increasing overall electricity loads, very nearly caused rolling blackouts.
