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.

Two-thirds of the nation’s wholesale electricity sales occur in a competitive market managed by a Regional Transmission Organization (RTO) or Independent System Operator (ISO), with over 200 million customers in these areas and over $120 billion in annual energy transactions taking place. Under the Federal Power Act, these markets are overseen by the Federal Energy Regulatory Commission (FERC), which ultimately determines the rules for how wholesale electricity is bought and sold in the marketplace. RTOs/ISOs develop the market rules that dictate whether and how energy resources can participate and compete. Wholesale electricity markets should allow all resources to compete on price and performance, as the Federal Power Act requires that the rates, terms, and conditions of service governing wholesale competitive markets be “just and reasonable” and not grant any “undue preference or advantage.” Many market rules, however, are outdated, having been designed with older technologies in mind. Those rules can favor incumbent technologies and disadvantage newer and more innovative energy options – that is, advanced energy.
