US utility Duke Energy has partnered with Anderson County to install a 5MW grid-tied battery energy storage system in South Carolina.
The battery storage system will be installed at Anderson Civic Center to provide up to 30 hours of backup power during outages.
The project is part of efforts by Duke Energy to invest $500 million in battery energy storage in the Carolinas over the next 15 years.
The system is claimed to be the first of its kind in Carolina and will be used for grid reliability during times when demand on the main energy network is high.
The system is expected to be operational by 2021.
Michael Callahan, president of Duke Energy in South Carolina, said: "Through projects like this, we're transforming the state's energy infrastructure to support the two-way flow of electricity and significantly improve reliability for our customers.
"The added benefit of this project is that – in the case of a power outage – the storage system can be dedicated to the Anderson Civic Center so this critical emergency facility will be able to support residents and evacuees in time of crisis."
Tommy Dunn, Anderson County Council chairman, added: "Power is critical at the Civic Center when our facility is being utilized as a command post for service providers and shelter to citizens who have been displaced. We are excited about the opportunity to partner with Duke Energy on this project that will benefit our community during times of disaster."
