Duke Energy's gets approval for grid modernization project with solar + battery microgrid and standalone battery system

The American electric power utility, Duke Energy, announced that regulators have approved two projects involving energy storage worth about $30 million. The first project is a microgrid for Madison County that will consist of a 2-MW (AC) solar facility and a 4.4 MW / 4.4 MWh lithium-based battery storage facility. The microgrid will provide a safe, cost-effective and reliable grid solution for the Hot Springs area as well as energy and additional bulk system benefits for all customers. The project is part of Duke Energy's grid modernization plan that it previously announced. The second project is a large battery storage project in the city of Asheville where Duke Energy will connect a 9-MW / 9-MWh lithium-ion battery system at a Duke Energy substation site in the Rock Hill community – near Sweeten Creek Road. The battery will primarily be used to help the electric system operate more efficiently and reliably for customers.
