Statistical Technical Guidelines for New Energy Storage Power Stations

This document, DL/T 2922—2025, provides statistical technical guidelines for new energy storage power stations, covering electrochemical, compressed air, flywheel, and supercapacitor energy storage types. It specifies requirements for basic information (e.g., station overview, type, parameters, access, assets, and electricity trading), equipment information, operation information, and statistical verification. The guidelines emphasize principles of authenticity, accuracy, completeness, and timeliness in data collection, processing, and verification, ensuring consistency with actual site conditions. Applicable to production and operation systems, it aims to standardize statistics across the power industry, supporting data quality control and security. The document was proposed by the China Electricity Council and drafted by multiple entities including State Grid and research institutes, with first publication in 2025.
