Energy Systems Integration

Energy systems integration is an approach to solving complex energy challenges that explores ways for energy systems to work more efficiently on their own, with each other, and with the electric grid. NREL's energy systems integration directorate employs a holistic approach to developing, evaluating, and demonstrating innovative technologies and strategies to ensure that our energy sources, demand-response programs, and delivery systems can work seamlessly together. The directorate is led by Associate Laboratory Director Juan Torres.
