Hitachi Energy to Supply 1100 kV Transformers for Nanyang Power Project in Central China
Hitachi Energy has announced it will provide high-voltage transmission equipment for Phase II of the Nanyang Power Plant in Henan Province, central China. The project includes the supply of 1100 kV gas-insulated switchgear (GIS), 1100 kV transformers, and generator circuit breakers.
The Nanyang Power Plant Phase II project is a key regional energy initiative with an installed capacity of 2,000 megawatts (MW). Once completed, the facility will strengthen the reliability of central China's ultra-high voltage (UHV) alternating current grid, enhance peak load management across Henan, and support large-scale renewable energy integration.
Under the agreement, Hitachi Energy will supply transformers and GIS equipment for the plant's 1000 kV step-up substation, which connects to the Nanyang 1000 kV UHV substation. These systems will enable efficient power transmission and stable grid operation within the regional UHV network.
The transformers will convert generator output into 1000 kV electricity for long-distance transmission, while the GIS system represents the product's first global deployment. The company says the GIS achieves leading performance metrics in electrical and mechanical reliability, compact design, and environmental sustainability.
Additionally, the generator circuit breakers provided will strengthen equipment protection, streamline operations, and reduce maintenance requirements.
Once Phase II is commissioned, the total installed capacity of Nanyang Power Plant will reach 4,000 MW, positioning it as a benchmark project for energy efficiency and operational reliability in central China.
