About

Rewbi uses AI to optimize grid-connected battery storage. We generate revenue by charging when electricity is cheap and discharging when electricity is expensive. We rent battery storage for a fixed fee per month, and we earn 2x that fee in monthly revenue by dispatching the battery optimally. Today, power companies use human traders to manually track grid conditions and update the battery’s dispatch schedule. However batteries can adjust their power output 100x faster than traditional power generation (e.g. hydro, coal, nuclear, gas), with the ability to go from full-speed charging to full speed discharging in under a minute. Electricity prices change every 5 minutes, often by 300% or more. Our AI better tracks 100s of live inputs, and it makes decisions faster than a human operator (with lower overhead!), improving revenue 2x.
