NEXTracker’s NX Flow energy storage product delivers integrated, versatile, investment-grade solutions that maximize energy production and storage

FREMONT, CA, USA, Dec. 6, 2017 —  NEXTracker™, a Flex company, today announced NX Flow™, a modular, integrated solution designed for long duration solar-plus-storage applications. The solution is designed to maximize long-term value and offers the lowest levelized cost of storage (LCOS) for a wide variety of applications, such as peak smoothing, bulk load shifting and demand charge reduction. NEXTracker’s energy storage product provides customers with configurable and intelligent solutions for new and retrofitted power plants and stand-alone applications.

“Customers face a complex set of technology decisions as they design their energy systems and solutions today. NEXTracker’s solution leverages our expertise in optimizing power plant technologies to help customers make the right choice for each specific project,” said Alex Au, CTO of NEXTracker. “NX Flow can be used for many energy storage and solar-plus-storage scenarios, offering our customers a wide range of choices. With NEXTracker’s Energy Storage Solutions, we are on the front line of mass-scale intelligent energy system development for modern power plants.”

Bloomberg New Energy Finance forecasts the global energy storage market will “double six times” by 2030, growing from less than 5 gigawatt-hours in 2016 to more than 300 gigawatt-hours. An estimated $103 billion will be invested in energy storage over that time period.[1] As the solar tracker market share leader for the second consecutive year, NEXTracker continues to execute on increasing global demand for smart tracking and storage systems in the large-scale solar power industry.[2]

NX Flow’s complete storage solution (formerly known as NX Fusion Plus) integrates battery, inverter, solar tracker and software technologies to improve return on investment for owners of solar power plants. At the core of the system lies an advanced vanadium flow battery (VFB), which is DC-coupled with the photovoltaic (PV) array for high round-trip efficiency. With NX Flow, the battery charges directly off the array, enabling the battery to capture “clipped” energy up to its storage capacity limit. Energy that has been lost to clipping can now be captured and used to generate additional kilowatt-hours revenue. Pairing NX Flow VFB technology with solar power offers a bankable long duration storage option for project developers and asset owners.

 NX Flow uses the below capabilities to ensure maximum value and performance, including:

  • Smart, connected technology. An industrial-strength cyber secure data platform by parent company, Flex, combined with NEXTracker’s predictive smart control software and Digital O&M™, offer complete cyber-secure system analytics and monitoring for critical operational parameters.
  • Robust, pre-engineered designs for lowest Balance of System (BOS) cost. Upfront design work is eliminated, speeding up deployment; advanced safety designs are compliant with leading authorities having jurisdiction (AHJ).
  • Global supply chain powerhouse. Backed by Flex’s award-winning supply chain expertise, NEXTracker can deliver solar trackers, storage and other power plant infrastructure technologies at scale.
