On June 27, the 100MW/200MW hour decentralized control grid type independent energy storage power station independently developed by China Huaneng achieved full capacity grid connection at Shandong Laiwu Power Plant, marking the official operation of the world's first 100MW level decentralized control grid type independent energy storage power station.

This energy storage power station is one of the 2022 energy storage demonstration projects in Shandong Province. It can store 200 MW hours of electricity in one charge and meet the daily electricity demand of approximately 30,000 households. After the project is put into operation, it will be included in the unified scheduling and management of the Shandong Power Grid, which can consume approximately 100 million kilowatt hours of new energy annually and reduce coal consumption by approximately 31,000 tonnes.
