G.E.S. – The European BESS. Smart, scalable and cybersecure.
Grid Energy Storages (G.E.S.) Oy is a Finnish energy-tech company and the first truly European battery energy storage system (BESS) provider. Our patented G.E.S. CORE™ sodium-ion platform uses no lithium and no critical imports. It is designed for Europe’s autonomy, energy security and resilience. For data centres, it provides backup resilience, peak shaving, grid flexibility revenue and better use of renewable energy. It also improves power quality: it suppresses flicker, harmonics and voltage disturbances, and smooths the rapid load swings of AI and high-performance computing. It comes in modular units that scale from a single site to multi-megawatt installations. Built on Nordic industrial thinking, our systems are safe, understandable, serviceable and long-lasting.
