Technical Regulations for Connecting Compressed Air Energy Storage Power Stations to the Power Grid

1 Scope

GB/T 46373-2025 is the Chinese national standard covering connecting a CAES plant to the network - the active and reactive power capability in both charge and discharge, the ramp rates and the response to dispatch, the fault ride-through and the protection, and the metering and communication with the control centre. First edition, under the China Electricity Council, and it belongs with the saline aquifer siting standard GB/T 46545.1-2025. In force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026.

This document specifies the general requirements for the grid connection of compressed air energy storage power stations, as well as power control, primary frequency regulation, operational adaptability, and power consumption. Technologies related to quality, relay protection and safety automatic devices, dispatch automation and communication, simulation models and parameters, grid connection testing and evaluation, etc. Require. This document applies to newly built, renovated, and expanded compressed air energy storage systems connected to the public power grid at voltage levels of 10(6)kV and above. Construction, operation, maintenance and overhaul of power plants.
