Storio Energy develops and operates energy storage solutions (batteries) for professionals in France around 3 uses cases: (1) Solar PV + Storage for businesses. The battery boosts self consumption and generates additional savings and revenues on our clients bill. (2) EV Charging + Storage: Buffer batteries help secure the energy needs of high-speed EV charging station, avoiding the need for an expensive grid connection. (3) Solar PV + Storage for IPPs. Batteries can generate additional revenues and reduce grid connection cost for large scale hybrid solar + storage injection projects. Storios core innovation is to operate these batteries in real-time through its software platform, leveraging their residual flexibility to provide balancing and ancillary services to the electrical grid. This means that in addition to having a local role generating savings on site, our batteries contribute to stabilizing the grid and accelerating the energy transition, which generates complementary revenues. Our goal is to constantly optimize the total value of our assets, and share these profits with our clients. Storio offers a turnkey solution, working with its clients from initial feasibility studies, to purchasing the batteries, installing them on site, and operating them seamlessly using our software platform during the 15+ years of operations. We also offer financing solutions - Storio can partially or entirely finance your storage projects. Check our website to learn more and get in touch with our team of energy storage experts !
