★ World's Largest Proven Coal Reserve — The Zhundong Mega-Basin
Xinjiang holds approximately 2.19 trillion tonnes of predicted coal resources — roughly 40% of China's total and the largest single coal reserve area on Earth. The Junggar (Zhundong) Basin alone contains an estimated 390 billion tonnes of identified reserves, dwarfing any single coalfield in Australia, the United States, or Russia. This extraordinary resource endowment has made Xinjiang a national "energy security battery": cheap pit-head coal powers large ultra-supercritical (USC) generating units that produce electricity sold at regulated prices to eastern provinces via UHVDC infrastructure. At current extraction rates, Xinjiang's coal could last thousands of years — which simultaneously makes it an incredible economic asset and a profound decarbonisation challenge. The strategic question for China's 2060 neutrality commitment is not whether Xinjiang can stop burning coal, but how fast and on what timeline, given the region's economic dependence on coal-fired power revenues.

Major Xinjiang Coal Basins & Fields
| Basin / Field | Location | Predicted Resources | Coal Type | Notable Feature |
|---|---|---|---|---|
| Zhundong (准东) | Eastern Junggar Basin, Changji | ~390 billion tonnes | Sub-bituminous; low sulphur | World's largest single contiguous coalfield; open-pit development |
| Hami (哈密) | Turpan-Hami Basin, East Xinjiang | ~570 billion tonnes | Bituminous + lignite | Site of Hami-Zhengzhou ±800 kV UHVDC pit-head coal power base |
| Yili (伊犁) | Yili Valley, West Xinjiang | ~480 billion tonnes | Low-rank lignite + sub-bit | Yili coalification complex; coal-to-gas + coal-to-liquid projects |
| Northern Slope Junggar (北疆) | Urumqi / Changji region | ~400 billion tonnes | Bituminous | Proximity to Urumqi industrial load; oldest mines in region |
| Southern Xinjiang (Kashi / Aksu) | Tarim Basin rim | ~60 billion tonnes | Bituminous | Under-developed; high elevation extraction challenges |
Coal Power Fleet — Pit-Head Ultra-Supercritical Units
Xinjiang's coal power strategy differs fundamentally from coal provinces like Shanxi or Henan. Rather than mining coal and transporting it by rail to coastal power plants, Xinjiang builds massive pit-head generating stations adjacent to open-cut mines and transmits the electricity via UHVDC lines. This "convert coal to electrons" model dramatically reduces rail freight (saving ~80 million tonnes of rail capacity per year), allows ultra-large USC units (1,000+ MW per unit) to run at very high utilisation rates, and delivers electricity to eastern demand centres at competitive cost.
Fleet Characteristics (2023)
- ~110 GW total coal capacity — largest provincial fleet outside Inner Mongolia
- USC units dominate — 600–1,000 MW per unit; steam parameters 600°C / 31 MPa (world-class thermal efficiency ~44%)
- Average utilisation 5,500+ hours/yr — higher than most provinces because units run as export baseload
- Flue gas desulphurisation (FGD) + SCR DeNOx required on all units >300 MW since 2015 — SO₂/NOx within EU standards
- Water consumption: Xinjiang's arid climate makes water-cooled condensers a stress point; air-cooled units increasingly deployed
- Flexibility retrofit programme: 20 GW of coal units being retrofitted for 40% minimum load operation to absorb solar/wind variability by 2026
| Power Base | Location | Capacity (GW) | UHVDC Line |
|---|---|---|---|
| Hami North Thermal Power Base | Hami | ~12 GW (operational+approved) | Hami-Zhengzhou ±800 kV |
| Zhundong Coal Power Base | Changji, Eastern Junggar | ~20 GW (phased build-out) | Changji-Guquan ±1100 kV |
| Urumqi / Northern Slope | Urumqi + Changji | ~35 GW (local + legacy) | Multiple AC interconnect |
| Yili Power Base | Yili Valley | ~10 GW approved pipeline | Yili-Huating proposed corridor |
★ China's Best Sunshine + Strongest Winds — Curtailment Now the Binding Constraint
Xinjiang possesses some of the world's best renewable energy resources. The Turpan depression has solar irradiance exceeding 2,000 kWh/m²/year — matching North Africa. The Dabancheng wind corridor (between the Tianshan range and the Turpan basin) is one of the highest sustained wind resource zones on Earth, with average speeds of 8–10 m/s at hub height. By end-2023, Xinjiang had installed ~55 GW solar and ~45 GW wind — together exceeding the total installed capacity of Australia. The constraint is no longer resource or technology cost: it is grid absorption. With 110 GW of coal baseload running at high utilisation to serve UHVDC export contracts, there is limited flexibility to absorb the variability of wind and solar. Curtailment reached 30%+ in 2016 before improving as UHVDC capacity expanded and coal plants underwent flexibility retrofits. By 2023 curtailment had fallen to ~10% for wind and ~8% for solar — still among China's highest, but improving rapidly with each new UHVDC line and storage addition.

Goldwind — Born in Dabancheng
Xinjiang is the birthplace of China's domestic wind turbine industry. Goldwind Technology (金风科技), now the world's largest wind turbine manufacturer by cumulative installed base, was founded in Urumqi in 1998 to service the Dabancheng wind corridor. The company's permanent magnet direct-drive (PMDD) technology — developed to reduce gearbox failure rates in Xinjiang's dusty, temperature-variable environment — became the global industry standard. Today Goldwind ships turbines from 3 MW to 16+ MW. Its Xinjiang origins mean the province has deep institutional knowledge of wind energy operations, and Xinjiang technicians and engineers staff projects across Central Asia and beyond.
| Xinjiang Wind Metric | Value (2023) |
|---|---|
| Total wind installed | ~45 GW |
| Dabancheng corridor capacity factor | 38–42% |
| Hami wind capacity factor | 35–40% |
| Wind curtailment rate (2023) | ~10% (down from 33% in 2016) |
| Goldwind market share in XJ | >30% of local installations |
| Average new turbine size (2023) | 5–8 MW onshore |
| 14th FYP wind target | 80+ GW by 2025 |
★ World's Highest-Voltage Power Lines — Xinjiang's Energy Export Infrastructure
The defining infrastructure of Xinjiang's energy system is its Ultra-High Voltage Direct Current (UHVDC) transmission network — the arteries that carry electricity from Xinjiang's coal fields and renewable energy bases to power-hungry provinces 3,000+ km away. The Changji–Guquan ±1,100 kV UHVDC line (commissioned 2019) is the world's highest-voltage power transmission line ever built, capable of carrying 12,000 MW across 3,324 km — equivalent to the entire generating capacity of a mid-sized country. Together, Xinjiang's two major UHVDC lines can export ~270 TWh per year, making Xinjiang the largest net electricity exporter of any Chinese province. This export revenue (~¥80 billion/year) is a cornerstone of Xinjiang's economic development strategy and underpins the commercial case for both coal power and the emerging renewable energy base.
Xinjiang UHVDC Lines — Technical Specifications
| Line | Route | Voltage | Capacity | Length | Commissioned | Primary Source |
|---|---|---|---|---|---|---|
| Changji–Guquan (昌吉—古泉) ±1100 kV | Changji (XJ) → Guquan, Anhui | ±1,100 kV | 12,000 MW | 3,324 km | June 2019 | Zhundong coal + RE base |
| Hami–Zhengzhou (哈郑) ±800 kV | Hami (XJ) → Zhengzhou, Henan | ±800 kV | 8,000 MW | 2,210 km | January 2014 | Hami coal + wind base |
| Yili–Huating (伊华) ±800 kV (proposed) | Yili (XJ) → Huating, Gansu | ±800 kV | ~8,000 MW (planned) | ~1,800 km | Planned ~2028 | Yili coal-to-gas + RE |
| AC Interconnection (750 kV) | Xinjiang → Gansu → Qinghai grid | 750 kV AC | ~4,000 MW exchange | Multiple corridors | 2010 onward | Flexible interchange |
West-East Power Transmission Volume (TWh/yr)
Changji–Guquan ±1100 kV — World Record Line
Why ±1,100 kV? The previous UHVDC record was ±800 kV. State Grid Corporation pushed to ±1,100 kV to: (1) carry more power without adding more lines; (2) reduce resistive losses per GW transmitted over 3,300 km; (3) demonstrate Chinese mastery of ultra-high-voltage engineering. The line uses new-technology extruded XLPE cable sections, custom-designed converter stations, and insulator string technology that operates in Xinjiang's extreme conditions (-40°C winter to +45°C summer). Line losses are ~5.6% end-to-end — better than many 500 kV AC lines of a fraction of the distance.
| Parameter | Changji–Guquan Value |
|---|---|
| World record (at commissioning) | Highest voltage DC transmission line ever built |
| Equivalent capacity | ~12 nuclear reactors running continuously |
| Transmission efficiency | ~94.4% (5.6% losses over 3,324 km) |
| Capital cost | ~¥40 billion (~US$5.5 billion) |
| Converter stations | 2 (Changji sending; Guquan Anhui receiving) |
| Electricity delivered per year | ~66 TWh (design capacity utilisation) |
| CO₂ displaced vs coal alternative | N/A (primarily transports Xinjiang coal power) |
The UHVDC Transition Question — From Coal Electrons to Clean Electrons
Xinjiang's UHVDC lines were built primarily to export coal-fired electricity under long-term purchase agreements with eastern province utilities. The Dual Carbon commitment (peak 2030, neutral 2060) forces a fundamental rethink: should these lines continue carrying coal electricity, or can they transition to carrying wind and solar power from Xinjiang's world-class renewable resource zones?
- UHVDC lines run at 70–80% utilisation carrying coal baseload 24/7
- Coal power plants earn stable revenue from long-term contracts with Henan/Anhui utilities
- Xinjiang government depends on electricity export tariffs (~¥80B/yr) for fiscal revenue
- Renewable energy bundled with coal to meet utilisation requirements but at low priority
- 14th FYP requires 50%+ renewable energy bundled in any new approved UHVDC corridor
- NDRC 2023 directive: new Xinjiang coal-fired capacity must pair with 1:1 renewable capacity
- Storage (4–8 hour BESS) being built at UHVDC sending terminals to firm renewable output
- Green hydrogen electrolysis proposed for surplus wind/solar periods — avoiding curtailment

Xinjiang Electricity Mix Scenarios (TWh, 2023–2045)
Xinjiang Clean Energy Policy Timeline
- 1997
Dabancheng Wind Farm Phase 1 opens near Urumqi — China's first large-scale wind project. Uses imported Bonus (Denmark) turbines. Xinjiang Wind Power Development Company is established; becomes the predecessor entity to Goldwind Technology. The project demonstrates that China has world-class wind resources and launches the nation's domestic wind industry. By 2000, Goldwind is manufacturing its own turbines adapted for Xinjiang's extreme climate conditions.
- 2005
China's Renewable Energy Law enacted — mandates mandatory grid purchase of renewable energy and sets feed-in tariff framework. For Xinjiang, this triggers a first wave of wind farm development across the Hami and Dabancheng corridors. Coal production simultaneously ramps up as Zhundong field begins systematic development. Xinjiang's "dual track" energy economy begins: fossil fuels for immediate revenue; renewables as future hedge.
- 2010–2013
Xinjiang declared a national "Energy Resource Base" under the 12th Five-Year Plan. Massive coal mine approvals in Zhundong (Changji Autonomous Prefecture) — including the Dajing #1 open-cut mine with 10 Mtpa capacity. Hami Renewable Energy Base approved for joint coal + wind + solar development. State Grid Corporation begins planning for Xinjiang UHVDC corridors. Wind curtailment first emerges as a problem as installations outpace grid capacity.
- 2014
Hami–Zhengzhou ±800 kV UHVDC line commissions — China's first major Xinjiang-to-East power corridor. 8,000 MW capacity. Begins transforming Xinjiang into a net electricity exporter at scale. Bundled coal + wind power delivery model established. Wind curtailment hits 20%+ as coal capacity from Hami base fills transmission capacity. National Development and Reform Commission establishes Xinjiang as a priority zone for coal power base development.
- 2016–2018
Wind curtailment in Xinjiang peaks at 33% (2016) — the highest of any Chinese province. The State Grid Corporation and NEA launch emergency "coal flexibility retrofit" program, requiring coal plants to reduce minimum stable load from 50% to 40% to accommodate wind variability. Solar tariff cuts begin reducing cost of new PV. Xinjiang solar installed capacity crosses 10 GW. NDRC imposes a moratorium on new wind approvals in high-curtailment provinces — constraining Xinjiang's growth temporarily.
- 2019
Changji–Guquan ±1,100 kV UHVDC line (world record voltage) commissions — adding 12,000 MW of export capacity from Zhundong base. Curtailment begins rapid improvement as new transmission capacity opens. China's National ETS design finalised; Xinjiang's 200+ coal power plants face carbon pricing for first time. NDRC lifts wind development moratorium in Xinjiang; new solar and wind projects approved in large volumes. Total renewable capacity crosses 30 GW.
- 2020
Xi Jinping's Dual Carbon announcement (peak 2030, neutral 2060) — Xinjiang faces the deepest structural question of any province: how to manage eventual coal decline while maintaining economic stability. Xinjiang's 14th Five-Year Plan targets coal peak by 2025 and 100 GW of renewable capacity by 2025. New NDRC directive: any new coal-fired power approved in Xinjiang must be paired 1:1 with renewable capacity. Coal production continues rising to meet national energy security demands during global energy crisis.
- 2021–2023
Global energy crisis (2021–2022) leads China to accelerate Xinjiang coal production to ~450 Mtpa — ensuring national energy security. Simultaneously, solar + wind installations in Xinjiang surge: 30 GW of new renewable capacity added in 2021–2023. Wind curtailment falls to ~10%, solar curtailment to ~8% as BESS co-location becomes mandatory for new large-scale solar projects. Green hydrogen pilot (300 MW electrolysis) announced in Hami — China's largest single green H₂ project. NDRC approves Yili–Huating ±800 kV UHVDC feasibility study for coal-to-renewables transition corridor.

Primary Energy & Electricity Revenue Flows (¥B, 2023)
Xinjiang's Energy-Dependent Economy — Three Pillars
Coal mining, coal power generation, and coal chemical industries (coal-to-liquid, coal-to-gas, methanol, polyolefins) account for the largest single share of Xinjiang GDP. The Tarim Basin also holds China's 3rd-largest natural gas reserves (~3 trillion m³) and 15th-largest oil fields. CNPC Tarim operations produce ~35 billion m³/yr of natural gas piped to eastern China via the West-East Gas Pipeline (a parallel energy corridor to UHVDC). Coal production revenue of ~¥200B/yr and electricity export revenue of ~¥80B/yr are the bedrock of Xinjiang's fiscal position. Any rapid coal phase-out without replacement income would be a severe economic shock — making a managed transition critical.
Xinjiang is China's largest cotton producer (~85% of national output) and a major source of tomatoes, grapes, hops, walnuts, and stone fruits. Agriculture in this arid region is entirely dependent on glacier meltwater from the Tianshan and Kunlun ranges — a water supply directly threatened by accelerating climate change. Energy is crucial for agriculture: electric pumps lift water from deep wells and canals; greenhouses in Turpan require heating; cotton ginning is electricity-intensive. The intersection of energy transition and water stress makes Xinjiang's agricultural sector one of China's most complex climate vulnerability cases. Solar-powered drip irrigation systems are being deployed at scale to reduce energy and water consumption simultaneously.
Xinjiang's ultra-cheap electricity (¥0.25–0.30/kWh — among China's cheapest) is actively attracting energy-intensive industries from eastern provinces. Data centres (Alibaba, Tencent, JD.com all operating or building in Urumqi), silicon metal smelting for solar panels, polysilicon production (Daqo New Energy, Xinte Energy — two of China's top polysilicon producers operate massive Xinjiang plants), aluminium smelting, and electrolytic manganese are all relocating or expanding in Xinjiang to exploit cheap power. This "power carving" industrial strategy aims to transform cheap energy into higher-value products locally rather than exporting raw electricity.
Industrial Electricity Consumption by Sector (TWh, 2023)
★ Xinjiang's Transition Opportunity — The World's Largest Renewable Energy Base
Xinjiang's paradox is that it holds both China's largest decarbonisation challenge (its coal industry) and some of its greatest clean energy assets (solar + wind resources rivalling the Sahara). The strategic opportunity is to leverage the existing UHVDC export infrastructure — built for coal — to transition to exporting renewable electricity as coal plants are retired. Three mega-opportunities shape this transition.
