Hitachi ABB Power Grids is to upgrade the gas-insulated switchgear (GIS) and monitoring solution at Hubei Qingjiang Hydropower Development Company’s Geheyan hydropower plant in central China.
Operational since 1994, the Geheyan hydropower plant was the first of its kind on the Qingjiang River, a tributary of the Yangtze River. It plays an important role in China's hydropower development history and is contributing to China’s long-term goal of becoming carbon-neutral. With an installed capacity of 1.2GW, it is the backbone power plant for peak load shifting and frequency regulation in central China’s power system. Over the years, it has contributed to social, economic and environmental developments in the region.
To ensure the aging power plant continues to operate smoothly, Hitachi ABB Power Grids will replace third party GIS, upgrade and install 550kV, 220kV GIS and high-voltage bushings for transformers. The equipment upgrade will greatly enhance the reliability of the power plant and minimize power losses.
