Oncor

Oncor, Texas' largest transmission company, is installing five lithium-ion batteries this summer in South Dallas neighborhoods, providing backup power to schools, traffic lights and a fire station. With the capacity to each store 50 kWh of energy — enough to power three to five houses for three hours — the batteries are designed to kick in when the electricity trips off, whether because of a falling branch or equipment issues.
