TerraSol Energies selects ESS iron-flow battery for Pennsylvania recycling facility

ESS iron flow battery

ESS was selected by TerraSol Energies to deliver an ESS Energy Warehouse flow battery at a commercial facility in Pennsylvania. The Energy Warehouse system will be integrated with solar PV as part of a microgrid to reduce electricity demand charges and provide safe, sustainable backup power to Sycamore International.

“Sycamore International is a highly discerning, environmentally conscious customer that wants a clean and reliable long-duration storage solution paired with solar to ensure energy security and resilience at their facility,” said Dave Santoleri, President of TerraSol Energies. “The ESS Energy Warehouse delivers the right combination of performance, value and long operating life, at a superior levelized cost of storage metric.”

Commercial and industrial (C&I) energy users routinely face steep demand charges based on peak usage periods, in addition to general energy consumption costs. By utilizing long-duration energy storage to shave electricity use during these peak periods, companies can realize significant savings, leverage renewable energy resources to reduce their carbon footprint and provide resilience against power outages from extreme weather events and other causes.

“Power outages have a huge impact on our business – costing upwards of $40,000 per day in lost revenue,” said Steve Figgatt, CEO of Sycamore International. “We needed a solution that would ensure long-duration backup power when needed, with a favorable ROI and no safety issues. We ruled out lithium-ion batteries and other flow battery chemistries due to toxicity and cost. ESS’s iron-based flow battery offers the right combination of safety and sustainability with long asset life to match the expected life of our solar power system.”

“C&I customers are becoming increasingly aware of the cost and resilience benefits that long-duration energy storage can bring to their operations,” said Hugh McDermott, Senior VP of Sales and Business Development. “At the same time, there is an accelerating demand for sustainable storage solutions that are safe for both people and the planet and do not rely on rare earth minerals and components with supply chain risks. Our flow battery products utilize iron, salt and water – ingredients that are easily sourced – and are made in America with domestic components, offering a core strategic technology to enable the global energy transition.”
