About the Company 

Wattsto Energy is a long-duration energy storage innovator based in Houston, Texas. It turns storage into financeable infrastructure, making renewable power more reliable and scalable. Wattsto Energy delivers solutions for both grid-scale projects and off-grid microgrids. Its microgrid work spans island systems, remote regions, and mid-to-large commercial and industrial users, enabling clean, independent, and resilient energy. Its edge comes from: its next-generation battery systems, engineered for decades of safe, sustainable operation; the MERIT Protocol™—a proprietary energy protocol forming the foundation for Energy-as-a-Service (EaaS); and a Greentown Labs membership that builds ecosystem partnerships to connect technology with capital and markets.

About the Solution

Energy delivers long-duration storage based on vanadium redox flow batteries (VRFBs) using Wattsto Energy’s unique hybrid design for Li-ion BESS. Features include VRFBs with 10-hour standalone storage to directly address the duck curve by shifting surplus to peak demand; hybrid Li-ion BESS—its proprietary architecture which offloads deep cycling to VRFB, extending the lithium system lifespan by 30% and protecting investor asset value; non-flammable and fully recyclable electrolytes; and scalable systems from 500 kWh to 500 MWh. These features, paired with Wattsto Energy’s AI-driven EMS/BMS systems, optimize operations and unlock revenues from peak shaving, frequency regulation, capacity markets, and carbon credits.
