China Advances 14.6 GW Integrated Renewable Energy Base
China Datang Corp. is planning a massive 14.64 GW integrated renewable energy project in China’s Inner Mongolia Autonomous Region, combining large-scale solar, wind, battery storage, and coal-fired generation linked to long-distance ultra-high-voltage transmission infrastructure.
According to project details released by Datang International Power Generation Co., the development will include approximately:
- 8 GW of solar power
- 4 GW of wind power
- 2.04 GW / 8.16 GWh of battery energy storage
- 2.64 GW of coal-fired generation capacity
The project is intended to transmit electricity from resource-rich Inner Mongolia to the energy-intensive eastern province of Jiangsu through a planned 800 kV ultra-high-voltage direct current (UHVDC) transmission line with an 8 GW transfer capacity.
The proposed transmission corridor would extend approximately 1,886 kilometres, connecting converter stations in Ordos and Nanjing while crossing several Chinese provinces including Shanxi, Hebei, Shandong, Henan, and Anhui.
Datang said the project will be developed through a newly established joint venture called Datang (Ordos) Energy Development Co., Ltd., formed in partnership with Jiangsu Guoxin Group and Ordos New Energy Development and Utilization Co., Ltd..
The joint venture will have registered capital of approximately CNY 10 billion ($1.47 billion), with Datang holding a 51% stake, Jiangsu Guoxin Group 34%, and Ordos New Energy Development and Utilization 15%.
Total planned static investment for the wider project is estimated at approximately CNY 58.1 billion ($8 billion).
The project is designed as an integrated wind-solar-coal-storage energy base, where coal-fired generation and battery storage systems are intended to provide balancing capacity for intermittent renewable energy production and improve utilization of the long-distance transmission system. Datang said the configuration could reduce renewable energy curtailment rates to below 1%, compared with regional averages of around 10%.
The development reflects China’s continued expansion of large-scale renewable energy bases and UHV transmission infrastructure aimed at transporting electricity from western and northern generation regions to eastern industrial centres.
China remains the world’s largest renewable energy market, with rapid deployment of utility-scale solar, wind, and storage projects continuing under the country’s latest energy transition and grid modernization plans.
