Duke Energy’s 11MW/11MWh battery storage project, despite modest size, is thought to be the largest project of its type in North Carolina.

Duke Energy would still choose lithium-ion for an upcoming 7.3-hour duration energy storage system in Florida if it redesigned the project today, a spokersperson told Energy-Storage.news.

Duke Energy’s carbon reduction plan for its Carolina businesses includes proposals for a “significant growth” in energy storage deployments.

Honeywell and Duke Energy will jointly develop and deliver microgrid solutions to US cities.

The US could see new mines and raw material production “scale up” as demand for battery energy storage systems and grid resilience increases over the next decade, according to Margaret O’Riley, battery, automotive and electrification business recruitment lead for Duke Energy Corporation.

Major US utility company Duke Energy has announced the first grid-scale battery energy storage project to be built in the service territory of Duke Carolinas, in Anderson County, South Carolina.

Once again, lithium-ion battery-based solutions have been selected for projects that will “improve overall reliability” of electricity supplies, to enhance the grid and make it more efficient, while also providing backup in case of outages.

North Carolina-headquartered utility Duke Energy has agreed to sell a minority stake in a roughly 1.2GW portion of its renewable energy portfolio for US$1.25 billion.
