Optimized for applications from one to four hours in duration, the SLD technology will be offered as part of NEC Energy’s GSS platform and will be available for installation from first quarter of 2016.

Offered as complete turnkey systems as well as standalone DC racks and containers, the technology will make use of lithium-ion cells based on NEC’s lithium manganese oxide chemistry.

NEC Energy Solutions CEO Bud Collins said: "With the introduction of our new SLD technology, we are able to increase the value of energy storage to enable applications like peak shifting, primary reserve, renewable integration, and peaking power.

"We’ve been engineering and testing these systems for over a year to ensure they meet our highest standards for safety and reliability, necessary to deliver the performance and certifications our customers expect.

"Installed in container farms or buildings, these SLD systems will provide up to 140MWh of energy storage – with power conversion, controls, and thermal management systems – per acre of land."
