China Huaneng has fully grid-connected a 960 MW wind-solar-storage project in Ulanqab, Inner Mongolia, in a new step for combining wind, solar and battery storage into a single plant that can also help an existing coal-fired power station run more flexibly.
The project was developed by a subsidiary of China Huaneng, one of China’s largest state-owned power producers. It was reported on 21 October 2026 by TaiyangNews, citing China Huaneng, and the company describes it as the first project of its kind in China.
What the Huaneng wind-solar-storage plant contains
The facility combines 810 MW of wind power with 150 MW of solar power, a 60 MW/240 MWh grid-forming battery energy storage system and a 20 Mvar static synchronous condenser, all connected through a 220 kV step-up substation.
Once fully operational, China Huaneng expects the project to generate approximately 2.3 billion kWh of electricity a year.
The storage and grid equipment matter as much as the turbines and panels. Wind and solar output rises and falls with the weather, so the battery system stores electricity for use when generation dips, while the synchronous condenser helps keep the local grid stable. Pairing them with a coal plant retrofit is designed to let the older plant vary its output more flexibly instead of running at a fixed level.
Why Inner Mongolia is central to China’s clean energy build-out
Inner Mongolia holds some of China’s strongest wind and solar resources, and the region has become a testing ground for large hybrid plants that mix generation, storage and grid services.
In the same week, Inner Mongolia’s energy regulator published an implementation list covering five solar desertification-control projects in Alxa League with a combined capacity of 5.5 GW, showing how new solar capacity is being paired with land restoration in desert areas.
The wider context is a rapid global shift in energy spending. According to the International Energy Agency’s World Energy Investment 2026 report, global energy investment is expected to reach 3.4 trillion US dollars in 2026, with about 2.2 trillion dollars directed to clean energy technologies and infrastructure, including renewables, grids, storage and efficiency.

FAKTA
- What: A 960 MW wind-solar-storage project in Ulanqab, Inner Mongolia, fully grid-connected.
- Developer: A subsidiary of China Huaneng; the company calls it the first project of its kind in China.
- Make-up: 810 MW wind, 150 MW solar, 60 MW/240 MWh grid-forming battery storage, 20 Mvar static synchronous condenser, 220 kV substation.
- Expected output: Approximately 2.3 billion kWh of electricity a year once fully operational.
- Purpose: Combine wind, solar and storage in one plant and help retrofit a coal-fired power plant for more flexible operation.
- Regional context: Five solar desertification-control projects in Alxa League, Inner Mongolia, totalling 5.5 GW, were listed by the regional energy regulator in the same period.
Conclusion
The Ulanqab project shows where large-scale renewables are heading: not wind or solar alone, but hybrid plants where storage and grid equipment let variable generation behave more like steady, dispatchable power — and where older fossil plants are adapted to fit around clean energy rather than replaced overnight.
