Frequency regulation

Intermittent power generation from renewables and other sources, along with variable loads cause deviations from nominal frequency in the grid.

Energy storage systems are an attractive way to restore the balance between supply and demand, featuring rapid response and emission-free operation. The energy storage system is charged or discharged in response to an increase or decrease of grid frequency and keeps it within pre-set limits.

Hitachi Energy offers turnkey energy storage systems for power requirements ranging from hundreds of kilowatts to tens of megawatts, and including medium- or high-voltage grid connection. By choosing Hitachi Energy as a turnkey system provider, the customer gains a reliable partner for the overall system. Our project team acts as a single point of responsibility, thus minimizing project risk and complexity.
