The largest ever simulation of a transactive energy system shows potential economic benefits for the nation and a flexible grid ready to power the electrical, building and transportation sectors with clean renewal energy. The savings would equal the annual output of 180 coal-fired power plants nationally.
That savings could translate to economic benefits of up to $5 billion annually in Texas alone, or up to $50 billion annually if deployed across the entire continental United States.
The simulation showed that if a transactive energy system were deployed on the Electric Reliability Council of Texas (ERCOT) grid, peak loads would be reduced by 9 to 15 percent. “Because Texas’s grid is quite representative of the nation’s energy system, it not only enabled the modeling and simulation of transactive concepts but provided a reliable extrapolation of the results and potential economic impacts to the broader United States grid and customers,” he said. Hayden Reeve, a PNNL transactive energy expert and technical advisor, led a team of engineers, economists and programmers who designed and executed the study. The final multi-volume report was released today. That’s why the Department of Energy’s Office of Electricity called upon the transactive energy experts at Pacific Northwest National Laboratory to study how such a system might work in practice. But a transactive energy system has never been deployed on a large scale, and there are a lot of unknowns. This kind of flexible control over energy supply and use patterns is called “transactive” because it relies on an agreement between consumers and utilities. In this system, consumers would coordinate with their electric utility operator to dynamically control big energy users, like heat pumps, water heaters and electric vehicle charging stations. The largest ever simulation of its kind, modeled on the Texas power grid, concluded that consumers stand to save about 15 percent on their annual electric bill by partnering with utilities.
