CEEC’s Energy Storage System Powers Gansu’s Green Future: A 100MW PV Project in Gaolan County

Operational Impact‌

Transforming Energy and Industry

  1. Economic Impact:
    • 180 million kWh annual generation meets 30% of Lanzhou’s chemical park demand, cutting costs by 15%;
    • 4.5 – year payback period, 18% faster than industry norms.
  2. Environmental Leadership:
    • 76,000 tons annual CO₂ reductions, equivalent to 410,000 trees planted;
    • Recognized as a provincial “Hydrogen Development Key Project.”
  3. Industrial Catalyst:
    • Attracts 2 hydrogen enterprises with ¥3 billion in projected output;
    • Positions Lanzhou as a green hydrogen hub in western China.
  4. Social Value:
    • Trains 150 local technicians in renewable energy;
    • Increases rural household income by ¥6,000/mu through land leases.

Project Context

Solar Abundance Meets Industrial Transformation

   Gaolan County, Gansu Province, with 2,000 annual sunlight hours, hosts CEEC’s 100MW PV project, a key component of the Lanzhou Hydrogen Energy Industrial Park. With a ¥450 million investment, the project spans 3,837 mu and addresses three critical challenges

  • Grid Integration: Reduce Gansu’s PV curtailment through energy storage
  • Hydrogen Demand: Supply stable green electricity to Lanzhou New Area’s chemical park
  • Economic Growth: Generate ¥20 million in annual tax revenue, create 300 jobs, and benefit 500 rural households

A Triad of PV + Energy Storage + Hydrogen

CEEC’s innovative system features：
  1. Energy Storage Core:
  2. Hydrogen Synergy:
  3. Grid – Friendly Design
  • 20MW/40MWh lithium - ion ESS with ≤15 - minute response, reducing PV volatility from ±25% to ±5%; Daily 2 - cycle operations yield ¥5 million in annual revenue through peak - valley arbitrage.
  • Reserved hydrogen electrolysis interfaces allow future green hydrogen production costs below ¥25/kg;ESS provides millisecond - level power support for stable hydrogen generation
  • Decentralized generation with centralized grid connection via 110kV substation; Smart energy management optimizes PV, storage, and load in real time.
