Energy Storage for Frequency Regulation ... Alevo selected Nuvation Energy's battery management system to manage the batteries in their 2 MW /1MWh energy storage system ... A key reason they chose Nuvation Energy's BMS is because it can measure battery cells from 0 volts and accurately manage the charging process from 0% to 100% ... Managing this charging process requires highly accurate current readings and a level of precision that most battery management systems cannot provide. Alevo's high energy density cells had 99% availability and could be safely discharged to zero volts.  ... Today the Alevo Gridbank ESS pictured here continues to provide frequency regulation services to the PJM interconnect ... Nuvation Energy's Multi-Stack Controller provides parallel stack management and enables servicing of individual battery stacks without taking down the ESS. ...

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. ... Check out the video below to learn more about the 2 MW energy storage system we built. ... ... Project Details: ... Wastewater treatment plant, City of Santa Rosa, CA ... Spinning reserve, for diesel genset changeover in case of grid outage ... Custom ultra-compact 24-foot container due to siting constraints ... Outputs 2 MW for 15 minutes ... Capacity - 588 kWh ... PCS - Parker Hannifin 890GT-B, 2 MW, 1200 V DC ... NMC batteries ... Nuvation Energy turnkey custom energy storage system design (racks, battery selection, pack & rack design, container, HVAC, fire suppression, PCS, etc. ... https://www.youtube.com/embed/9LZjIsXmklI.

Energy Storage for PV Smoothing ... Stalwart Power selected Nuvation Energy's battery management system to manage their 50 V battery energy storage system for grid-attached, behind-the-meter energy storage ... The Stalwart system was a 17.5 kWh lithium-iron phosphate energy storage system that utilized a Schneider PCS. ... ... Stalwart selected batteries for the system, but needed to replace the manufacturer’s bundled battery management system because it was not designed to support deployment at the utility. ... Stalwart chose to replace the battery manufacturer's BMS with Nuvation Energy's BMS due to its remote monitoring capabilities ... Nuvation Energy battery management systems can be used to remotely monitor an energy storage system and flag potential issues that would merit a service call, before those issues impact system safety or performance. ... Nuvation Energy performed all aspects of system integration for this project ... Our software team also developed a custom site controller that performed PV smoothing and load balancing functions. ... Project Details: ... PV smoothing and load shifting ... 50 V DC, 17 kWh, LiFePO4 battery stack, Schneider PCS ... Ethernet communications, remote access to performance data and BMS controls ... Created custom PV smoothing, load shifting algorithms and site controller ... Performed all system integration and testing ... Installed in the field at a utility in Atlanta, Georgia, with on-site support from Nuvation Energy.
