These dispatch events come as grid operators scramble to prevent rotating blackouts amid a triple-digit heat wave sweeping the East Coast. The prolonged heat has caused congestion and overheating of transmission lines, leading to sharp increases in wholesale electricity prices. As soaring temperatures reduced the efficiency of traditional power plants, utilities struggled to meet skyrocketing demand for electricity. “This summer is proving challenging for grid operators, as extreme heat and rising demand again push our aging infrastructure to its limits,” said Sunrun CEO Mary Powell. “Home storage paired with solar is a reliable and controllable resource that can provide on-demand power to the grid to prevent blackouts and reduce energy prices for all households. We must fully embrace these technologies if we’re to achieve energy security for America.” On Tuesday evening, Sunrun answered urgent requests for emergency power by dispatching stored energy in home batteries to the grid during sweltering heat along the East Coast. The influx of power from thousands of Sunrun batteries helped fill the gap of energy reserves while reducing the need for expensive and polluting peaker power plants. In New York, Sunrun completed its fourth dispatch event within the last week, helping relieve stress on congested circuits identified by the utility partner. Three more power-sharing events in New York are scheduled for the coming week. In Puerto Rico, Sunrun activated more than 5,600 batteries in less than one hour to assist the island’s utility provider during power generation shortfalls. In California, Sunrun’s fleet of home batteries enrolled in a statewide distributed power plant dispatched 325 megawatts of peak power. The dispatched batteries acted in the same way as a traditional power plant and decisively knocked down the state’s evening peak demand for e...
