CEEC’s Energy Storage System Illuminates Xinjiang’s Gobi Desert – A New Benchmark for PV + Storage in Shihezi

Operational Impact‌

Economic and Ecological Leapfrog

  1. Cost Savings:
    • 20% reduction in electricity costs for high – energy industries, saving ¥12 million annually;
    • 4.2 – year payback period, 20% faster than industry averages.
  2. Grid Efficiency:
    • PV curtailment reduced from 8% to 3.5%, increasing green power generation by 12 million kWh;
    • Capacity utilization hours increased to 1,550, 10% higher than Xinjiang’s average.
  3. Environmental Impact:
    • Annual savings of 9,200 tons of coal, reducing soot by 1.83 tons and SO₂ by 6.24 tons;
    • Recognized as a “14th Five – Year Plan” 示范 project, attracting 300MW of additional PV investments.
  4. Industrial Synergy:
    • Stable electricity prices attract 3 silicon – material plants with projected ¥5 billion annual output;
    • Trains 200 local renewable energy technicians, transforming employment structures.

Project Context

Dual Challenges of Electricity Price Hikes and Grid Absorption

Annual effective sunlight of 1,400 hours in Shihezi’s 148th and 150th Regiments； High – energy industries in Shihezi require sustainable alternatives to coal – fired power.

  • Cost Pressure: Planned electricity price increases from ¥0.25/kWh to ¥0.30/kWh threaten profitability
  • Grid Absorption: Xinjiang’s historical PV curtailment rate of 8% (2019) undermines renewable energy stability
  • Annual CO₂ reductions of 25,100 tons, equivalent to planting 138,000 trees

"PV + Storage" Solving Grid and Cost Challenges

CEEC’s innovative integrated system features:

  1. Dynamic Grid Optimization:

  2. Peak – Valley Arbitrage:

  3. Grid Support:

  • 20MW/40MWh lithium - ion ESS with millisecond - level response to smooth PV output fluctuations; AI - driven algorithms predict solar irradiance and load demands for optimal charging/discharging.
  • Charges at off - peak hours (23:00 - 07:00) and discharges during peak hours (10:00 - 16:00), leveraging ¥0.30/kWh price differences; Daily 2 - cycle operations generate annual revenue of ¥6 million.
  • Reduces PV volatility from ±20% to ±5%, enhancing grid stability
