About Cactos

Cactos is a Finnish energy technology company that develops cloud-controlled, distributed battery energy storage systems (BESS) built on recycled EV batteries. Their flagship product, Cactos One, automatically optimizes energy use for commercial and grid-scale customers by charging during cheap hours and discharging during peak demand, while also providing backup power and enabling participation in ancillary grid services markets. Their proprietary software platform, Cactos Spine, aggregates distributed storage units into a virtual battery to support grid stability and renewable energy integration.
