• China Energy Engineering Group Shanxi Electric Power Survey and Design Institute Co., Ltd. won the bid for the EPC general contracting project of infrastructure supporting the Datong Economic Development Zone Green Power Park for approximately 1.086 billion yuan. This marks a substantial step for Shanxi Province in promoting the strategic transformation of energy structure and deepening the supply side reform of old industrial bases. This project is far from a single photovoltaic station construction, but a systematic project covering all aspects of "power generation, transmission, storage, and regulation". The core construction content includes: a planned photovoltaic matrix with a capacity of 300MW (360MWp on the DC side), a key 110kV booster station, and a high-grade transmission line with a total length of over 40 kilometers, ultimately converging into a comprehensive substation that integrates photovoltaic, wind power, energy storage, and regulation functions.Editor/Bian Wenjun
