San Francisco-based Zenergy Power Inc., a global firm developing high-efficiency, renewable energy devices that capitalize on superconductor technologies, has been contracted by Consolidated Edison Co. (Con Edison) to build and test a smart-grid device for improving the stability and reliability of New York City's electrical system.

The equipment, known as a fault current limiter (FCL), instantly detects and absorbs spikes in power that, left unmanaged, could damage electrical equipment or trigger power outages, according to the company.

Con Edison, a subsidiary of Consolidated Edison Inc., authorized a project to design, build and test a single-phase FCL of a type that would be applicable to a number of substations within the utility's electrical system. Zenergy expects to deliver the prototype by the end of August.

"Fault current limiters will be an essential element of the smart grid to maintain reliability and improve its resilience and flexibility," says Pat Duggan, a Con Edison project manager and an FCL specialist.

At the conclusion of testing, Zenergy expects to extend its designs to other FCLs that are customized for protecting Con Edison and other utilities' equipment on higher voltage lines of up to 138 kV.
