1. TCP Offshore Wind Farm: 5.2-MW Wind Turbine Generators
At the TPC Offshore Wind Farm – Phase 1 Demonstration Project (the Project), for which Hitachi, Ltd. and its consortium partner, Jan De Nul nv (JDN), were awarded the engineering, procurement, and construction (EPC) contract from Taiwan Power Company (TPC), the installation and commissioning of 21 units of Hitachi’s 5.2-MW wind turbine generators (HTW5.2-127) have been completed, and all 21 units have been in operation since December 2021. As the Project is the first oversea and first offshore project for Hitachi’s wind turbine generator division , it has encountered various challenges, some of which were exacerbated owing to the COVID-19. Hitachi believes that these experiences can be utilized not only in the future offshore projects in the Japanese domestic market but also in the construction and operation and maintenance (O&M) of larger wind turbines.
In this Project, the consortium of Hitachi and JDN was also awarded with the 5 years of O&M scope, and today, the consortium continues to accumulate and digitize the technical knowledge related to the operation, maintenance, and preventive maintenance of the offshore wind farm. Hitachi, by integrating such data into the Lumada model and using it, aims to contribute to the development of businesses related to the stable operation of wind power generation facilities, the life extension of existing wind turbines in Japan, and improvement of their availability.
