Greensmith Delivers Over One-Third of all U.S. Energy Storage Deployments in 2014

Greensmith Software Platform Manages Grid-scale Energy Storage Systems

Over one-third of all energy storage capacity installed in the U.S. in 2014 was delivered by Greensmith and is managed using the company's fourth generation software platform.

The result is based on the inaugural U.S. Energy Storage Monitor from GTM Research and Energy Storage Association (ESA), which reports that 61.9 megawatts of energy storage came online in the U.S. in 2014. Greensmith's advanced software platform was used to integrate grid-scale and behind-the-meter energy storage systems, five in total, including the single largest battery-based power system deployed globally in 2014, providing 24x7 frequency regulation services.

GEMS4, Greensmith's latest software platform, was used to integrate and manage all five energy storage systems, totaling 23 megawatts. The platform also integrated four new battery technologies including lithium-ion, flow and aqueous-ion – bringing the company's total to twelve battery types integrated since inception.

The GEMS software platform manages the complete life cycle of energy storage systems. The technology-agnostic platform integrates all storage system components including batteries and inverters, manages storage assets to optimize battery performance, and provides connectivity with utility SCADA systems. GEMS offers modules for various applications such as frequency regulation, ramp rate control, and renewables smoothing. In its fourth generation of development over six years, GEMS offers advanced algorithms, such as string balancing and loss mitigation, improving battery performance per dollar spent.
