Butuo ±800-kilovolt Converter Station will transmit electric energy generated by the Baihetan Hydropower Station to the economically developed areas of eastern China. The clean energy delivered will meet annual electricity demands for 75 million people, reducing coal consumption by 27 million tons. With an aim to apply lifecycle digital workflows, the project team needed integrated technology to streamline workflows, control project costs, and achieve digital deliverables. Leveraging ProjectWise and Bentley Open applications, the team established a connected digital environment for collaborative multidiscipline design and construction management. Through 3D modeling and visual planning, they reduced total land used for the station by about 10 hectares to save CNY 45 million and reduce the project’s carbon footprint. Working in an integrated digital ecosystem reduced design time by 30 days, shortened the construction period by 40 days, and saved approximately CNY 7 million in overall project costs. The interoperability of Bentley’s applications helped save two days delivering the digital models for operations and maintenance.
