Last August, thunderstorms in the United Kingdom triggered a loss of power generation that left 1.1 million consumers fumbling for a flashlight. As trains halted and traffic slowed, 475 MW of energy storage began discharging. A combination of batteries and other generators worked together to take 1 GW of demand off the system. In less than four minutes, grid frequency was returned to normal and power returned to customers. Blackouts are not particular to the UK. According to the U.S. Energy Information Administration, Americans lose approximately $150 billion to power outages each year. What’s less common is the use of advanced energy technologies like energy storage and distributed energy resources to increase reliability and keep the lights on. But that could change, if these technologies were allowed to compete in wholesale electricity markets on the basis of price and performance. Two new market briefs from AEE demonstrate why they should.
