Vistra expands residential battery aggregation program with Enphase Energy

Vistra (VST) announced an expansion of its battery aggregation program to include Enphase Energy’s (ENPH) IQ Batteries, further scaling its residential virtual power plant to strengthen grid reliability across Texas. The program, Battery Rewards, is offered through Vistra’s flagship retail electricity brand, TXU Energy, and allows eligible Enphase customers to earn incentives by exporting stored battery power to the grid during periods of high demand. “As Texas continues to expect rapid load growth, demand-side solutions are becoming increasingly important,” said Sam Sen, Vistra’s vice president of energy transition solutions. “By bringing additional flexible resources like batteries online during critical periods, we can strengthen grid reliability and serve more load using the infrastructure already in place.”
