Lockheed Martin has been selected to supply the “largest stand-alone commercially contracted” battery storage system at a US Army base in Colorado.
Lockheed’s 4.25-megawatt Gridstar lithium battery system is being installed at Fort Carson as part of an energy savings performance contract project to reduce costs and “increase energy resilience”, the company said on 21 August.
The battery system is being built by infrastructure firm AECOM.
Annika Moman, AECOM’s senior vice-president, said the Gridstar system was chosen because of its “unique modular architecture, allowing for a flexible design and a reduction in operational risk”.
Lockheed said last April it also planned to launch a flow battery energy storage system- based on what it said would be a new electrochemistry, comprising “engineered electrolytes”, within “little more than a year.”
The company told BEST Battery Briefing its proprietary flow battery, which would be marketed under the Gridstar storage brand, would be designed for utility-scale projects to provide “flexible, durable, and over six hours energy storage”.
