The ATE ESX system combines certified safety with true flexibility, offering modular energy storage solutions for buildings, outdoor units, and grid-scale applications.
Electricity frequency trading
Electricity trading can be compared to stock trading — but in reverse. When grid frequency is high, the system buys electricity; when frequency is low, it sells. This mechanism stabilizes the grid, prevents disruptions and blackouts, and ensures reliable electricity supply for society.
By leveraging these frequency services, the ATE ESX system not only strengthens energy resilience but also generates attractive income — reducing the need to import expensive electricity from other regions.
