Home – Energy – China is building a 250-mile “Solar Great Wall” in the middle of the Kubuqi Desert, with the goal of reaching an astonishing 100 gigawatts by 2030
China’s Kubuqi Desert is being reshaped into one of the most striking energy projects on Earth, a 250-mile solar corridor planned to stretch through Inner Mongolia and reach as much as 100 gigawatts of capacity by 2030.
NASA’s Landsat imagery shows how quickly the panel fields expanded between 2017 and 2024, turning a once sparse desert landscape into what officials and observers call a “solar great wall.”
The most eye-catching piece is the Junma Solar Power Station, where panels form a giant galloping horse. But the real story is not the design. It is the way China is trying to combine power generation, desert control, grid expansion, and energy security in one enormous bet.
The corridor is planned to run across sunny, flat terrain south of the Yellow River, between Baotou and Bayannur. NASA says the location is attractive because it has strong sunlight, open land, and proximity to industrial centers, all of which matter when you are trying to build power at this scale.
Once fully built, the Kubuqi project is expected to be 250 miles long and about 3 miles wide. So far, Chinese officials have said roughly 5.4 gigawatts have been installed, leaving a long road before the planned 100 gigawatts becomes a reality.
In practical terms, this is not just a map-making exercise. A 100-gigawatt target is the kind of number that turns energy policy into something ordinary people can feel through factories, data centers, air conditioning, and eventually the electric bill.
The Junma Solar Power Station was completed in 2019 and arranged to resemble a galloping horse. Guinness World Records says the image uses 196,320 panels and covers about 345 acres, making it the largest solar panel image on record.
That is a lot of hardware for a picture. NASA says the plant generates about 2 billion kilowatt-hours of electricity each year, enough to cover the annual electricity needs of roughly 300,000 to 400,000 people.
Why a horse? The symbol has strong cultural links to the region, according to Guinness, and “Junma” is commonly translated as “fine horse.” Still, the image works almost like a billboard that can be seen from orbit. China is declaring to the world its intentions for a clean-energy transition.
The most interesting part may be what happens under the panels. The elevated structures can slow wind, reduce evaporation, and create shade that gives grasses and crops a better chance to grow in a place known for sand and dryness.
That matters because renewable energy projects usually get judged by how many electrons they push onto the grid. In Kubuqi, planners are also trying to turn the project into a tool against desertification, one that helps hold down dunes instead of just sitting on top of them.
But this is where caution helps. Satellite data has shown greening around some solar projects in China, yet scientists are still studying how much these changes can reshape local ecosystems and whether they could affect rainfall patterns over time. No one should pretend that a desert becomes farmland just because panels arrive.
Producing power in the desert is only half the job. Moving it to the cities that need it is the other half, and that usually means new high-voltage transmission lines, storage, and grid rules that can handle the ebbs and flows of power according to the weather.
The Beijing-Tianjin-Hebei region is the major destination. China’s government says the Kubuqi Desert Ordos Central-Northern New Energy Base is expected to send about 40 billion kilowatt-hours of electricity annually to that region once complete, with more than half coming from clean energy.
For anyone stuck in a traffic jam under city smog, that part is easy to understand. Cleaner Cleaner energy means a cleaner city to get around. Yet power only matters at scale if it reaches the homes, trains, factories, and offices where demand keeps climbing.
There is a caveat here, and it is an important one. A major Kubuqi-linked project is designed to include 8 gigawatts of solar power, 4 gigawatts of wind power, 4 gigawatts of coal-fired power, and 5 gigawatt-hours of energy storage, according to a company filing reported by Reuters.
That does not erase the clean-energy significance of the project, but it does make the story less glamorous. The coal capacity is meant to support the grid when renewable output is uneven, though critics of coal-heavy systems often warn that fossil backup can become a long-term habit rather than a temporary bridge.
At the end of the day, Kubuqi is a reminder that energy transitions rarely move in a perfectly clean line. They look more like construction sites, full of compromise, cables, dust, and deadlines.
China’s desert buildout is happening against the backdrop of its already large solar lead. NASA cited Global Energy Monitor data showing that, as of June 2024, China had about 386,875 megawatts of operating solar farm capacity, roughly 51 percent of the global total.
That is why Kubuqi feels bigger than one project. It is part of a national strategy to use open deserts, state-backed developers, and long-distance transmission to feed major industrial and population centers.
The business angle is just as important as the climate one. Reuters reported that China’s Three Gorges Renewables planned an investment of about $10.99 billion in an integrated Inner Mongolia energy project, with construction slated to begin in September 2024 and grid connection targeted for June 2027.
The next few years will show whether the “solar great wall” becomes a working power machine or a spectacular symbol with bottlenecks. Watch transmission, storage, coal usage, and the actual pace of installed capacity. Those details will tell the real story.
For now, the galloping horse is doing its job. It grabs attention. The harder question is whether the vast panel fields around it can keep moving China toward cleaner power while restoring fragile land and sending electricity hundreds of miles away.
