When PowerChina Hubei Electric Engineering was hired as the engineering, procurement, and construction contractor to deliver an 80-megawatt ground-based photovoltaic power station, they faced several challenges, including a short 10-month schedule with a requirement to realize lifecycle digital twin application. They originally used third-party design software but quickly realized that it was inefficient and that they needed integrated dynamic modeling technology.PowerChina Hubei selected OpenBuildings Designer and OpenRoads for 3D modeling, as well as ProjectWise for collaborative design management. With Bentley, they developed photovoltaic design software for mountainous photovoltaic power projects. The solution optimized the design scheme, reducing land occupation and avoiding 40 potential rework scenarios to save more than CNY 800,000. Integrating SYNCHRO 4D accelerated construction by approximately 30 days. They used the Bentley iTwin platform to automatically generate digital twin models, avoiding approximately CNY 1 million in costs had the digital twins been developed at the operation stage.
