Cadenza Innovation installed its propagation protected 250kWh battery energy storage system, meeting UL9540 and NFPA855 requirements at NYPA’s headquarter building . The safe solution allowed the system to be installed 10 feet distance from the building and near a bus stop. The technology has now matured to its current implementation in the cost-effective Cadence BESS product series, with high and low voltage DC solutions, deploying Cadenza’s world leading safety with propagation protection between cells, modules and containers, at the same time as it is minimizing the ejection of flammable gases, literally eliminating the possibility of an explosion when the amount of flammable gases are kept below its lower flammability limits. The design principles used by the BESS installed at NYPA, where the same as the Cadence 3HV 3MWh battery system, with an even more robust fire wall protection and exhaust system initiated by continuous feedback of flammable gas monitoring. This protects assets and fire personnel from fire and explosions.

Cadenza Innovation provided its 40kWh Cadence UPS series battery rack suitable for IT and AI storage applications to back up the IT server at Wilton CT public schools. The battery deploys the MyCadenzaCloud for dual purpose, meeting not only UPS functionality of the IT equipment and protecting it against power surges, voltage sagging and other power quality issues, but also allows the school to participate in aggregating energy storage for Eversource, the local utility. The system now participates in Energy Storage solutions demand response program, performs daily arbitrage to offset electrical costs, at the same time at it is backing up the IT servers for the schools. This dual BESS/UPS use is unique for the Cadence product series and available also for AI Storage deployed in a Virtual Power Plant, having a 208VAC three phase circuit as well as an 48VDC circuit that can back up DC equipment without disruption during a power outage.

The administration of the school was delighted to be able to back up their equipment for several hours, instead of only a few minutes with the traditional battery technology. “If the power goes out, we can actually keep the administration fully functional between the emergency light and our internet services and ride out the standard outage that is at most about one hour in Connecticut. Even the phones are working during an outage!”

Cadenza installed one of its indoor battery systems at a furniture store in New Jersey to cut down electricity costs and provide backup power. Cadenza’s customer was Samba Energy, an EPC firm that had been contracted to install a solar system and a battery system to improve the store’s costly electrical useage. While the store significantly cut down its energy purchase by installing solarpanels, it still had issues with peak power which were especially costly during the summer months. MyCadenzaCloud was able to reduce the store’s maximum power demand from about 50kW during maximum useage to about 15kW, savings thousands of dollars. At the same time, energy arbitrage was deployed in the energy management system. Recent analysis, after a few years of operation, has shown that the battery system was fully “paid off” after 4 years. While the electricity tariffs in New Jersey in the past 3-4 years have increased by more than 40%, the furniture store’s electrical bills have been cut in half! The system selected was the Cadence CI481600, an 80kWh UPS/BESS system that is available in both C&I and AI Storage (VPP adopted software) configurations. The system is easily installed in standard server racks and has a combination of power buses used (208VAC, 240VAC, 120VAC, and 48VDC)

S&C Electric’s Gridmaster®, Cadenza’s preferred microgrid controller, was deployed to in a project building a microgrid with two nested microgrids at Ameren Corporation’s Technology Applications Center near the University of Illinois campus to support the center and a 1-MW residential load. Ameren is a utility company serving some 2.4 million customers.

S&C Electric Company provided its full EPC capability creating a nested 50-kW microgrid within a 1-MW microgrid, all interconnected at 12 kV. S&C oversaw the construction of both a 100-kW wind turbine and a 125-kW solar array for Ameren, and provide the utility with two 500-kW natural gas generators as additional alternative energy sources. Most importantly, S&C provided a 250-kW/ 500-kWh energy-storage capability that serves as the backbone of the 50-kW microgrid, enabling it to operate on 100% renewable generation.

S&C further supplied Remote Supervisory Vista® Underground Distribution Switchgear to integrate the various systems. It also provided SpeedNet™ Radios to support device communication. To provide the “glue” to make the various sources of generation work smoothly both on the main grid and within the islanded microgrid, S&C deployed the GridMaster® Microgrid Control System. Nine IPERC cybersecure, adaptive, and distributed Intelligent Power Controllers were installed on the system to provide control functionality of the microgrid.

This “first-of-its-kind” solution enabled Ameren to be the first utility company to operate a microgrid system that can conduct a seamless return to utility power after entering microgrid mode at utility-scale voltages. This technology will become immensely important as AI data storage centers develop, requiring flexible and adoptable solution ranging from local power generation to backup and grid interactive battery systems to high voltage utility interconnections for urban environments.
