Energy Storage System Prototyping ... Nuvation Energy prototyped and built an energy storage system using second life Nissan Leaf batteries ... The batteries were no longer sufficient for powering electric vehicles ... However, at 70% state of health, they were perfect for use in stationary energy storage. ... Using the second life batteries, our team built a behind-the-meter energy storage system at Nuvation Energy’s headquarters in Silicon Valley ... There are several electric vehicle charging stations in the parking lot, where employees plug in their vehicles when they get to work ... Unfortunately, this tends to be during peak demand time, when it costs more to use electricity. ... Our second life energy storage system allows employees to charge their vehicle during peak demand times, without Nuvation Energy incurring peak usage charges ... At night, we hook the system up to the grid to charge the batteries when energy is less expensive ... In the morning when energy costs are higher, we use the system to charge employee electric vehicles off-grid. ... Check out these videos to learn more about our energy storage system or continue reading to see how this prototype has been commercialized. ... Project Details: ... 24 kWh stack, 360 V DC, 48 Nissan Leaf second life modules ... Designed site controller with load-shifting to manage demand charges ... Standard 19” rack ... Residential and commercial behind-the-meter or grid-attached ... Battery trays easy to install and service ... Installed a pair of Nuvation Energy BMS 12-channel Cell Interfaces on each tray ... .

Custom Energy Storage System ... Trane selected Nuvation Energy to build a custom energy storage system (ESS) for a wastewater treatment plant in the City of Santa Rosa, CA ... The plant employs backup diesel generators as part of their demand charge management system ... It can take a few minutes for the diesel generators to get fully ramped up and online ... Nuvation Energy created a custom energy storage system that could be used for demand charge management and facilitate the seamless transition from the utility grid to the diesel gensets. ... To support the high power demand requirements of the treatment plant, the ESS can output 2 MW for 15 minutes ... In addition to this unusual power requirement, the approved site was not large enough to support a standard 40-foot containerized ESS ... So Nuvation Energy worked with ESS container manufacturer Eco-H to build a compact 24-foot container.  PCS integration and final testing before field deployment were performed at Parker Hannifin - Energy Grid-Tie Division in Charlotte, NC. ...

Residential Solar Plus Storage ... GS Yuasa chose Nuvation Energy’s Low-Voltage System Assembly and Stack Switchgear (SSG) for their solar plus storage solution installed in Bright Power’s solar photovoltaic (PV) system ... The PV system was installed at Via Verde, a residential development located in the Bronx, New York City. ... New York City suffered from severe power outages during Hurricane Sandy in 2012 ... Jonathan Rose Companies and Phipps Houses, the developers of the Via Verde residences, built affordable housing that provided reliable energy to a community that was harshly impacted by the hurricane ... They built a 300,000 square foot urban infill, which included Bright Power’s 66 kW building-integrated PV system ... The solar system provides affordable energy to residents, cutting annual electricity costs by $13,000. ... Nuvation Energy’s integrated battery management solution was obligatory for GS Battery’s energy storage system to pass UL 1973 certification, a requirement for all new energy storage systems being deployed in New York City ... The BMS protects the batteries from overcharging and over-discharging, and provides thermal management ... Using Nuvation Energy BMS provided such robust battery protection that GS Yuasa doubled their battery warranty from five to ten years for clients who selected to integrate it into their lead-acid energy storage systems. ... Project Details: ... Residential development in the Bronx, New York ... 72 kWh of energy storage ... Custom solution for GS Yuasa SLR1000 ... Lead-acid batteries ... UL1973 certified ... nDisplay (operators interface) allows system monitoring and management ... Nuvation Energy provided low-voltage system assembly and Stack Switchgear ... .

Solar Energy Storage for Island ... Civic Solar chose Nuvation Energy to provide battery management solutions for Islas Secas, a 100% solar powered island resort off the coast of Panama. ... The island microgrid is powered by a 355 kW photovoltaic (PV) array ...
