Overview

AttributeValue
SSS Relevance⭐⭐⭐ High (regional)
Market TypeState-controlled with partial reform
Key Clean ResourcesHydro (13%), Nuclear (5%), Wind/Solar (18-23%)
EAC SystemGEC (Green Electricity Certificate), I-REC
Grid Carbon Intensity~550-600 gCO2/kWh

China has the world's largest electricity system, still dominated by coal (~58%) but with massive clean energy expansion. Nuclear capacity is growing rapidly (29 reactors under construction), and China leads global renewable installations.

SSS Relevance

⭐⭐⭐ High (regional) — China has significant but complex SSS potential:

  • Growing nuclear fleet (~55 GW operating, 29 reactors under construction)
  • Massive hydro (Three Gorges + many others, ~13% of generation)
  • Rapid renewables growth — but often tracked via GECs
  • Regional variation — clean energy concentrated in certain provinces

SSS-Eligible Resources

Resource TypeCapacity/OutputSSS Classification
Nuclear~55 GW, ~5% of generation✅ Potentially SSS — not GEC-tracked
Legacy Hydro~400 GW, ~13%⚠️ Much tracks via GEC; large legacy plants potential SSS

Operating Nuclear Plants: 55+ operating reactors at ~20 sites (Daya Bay, Qinshan, Taishan, etc.)

Note: China leads the world in nuclear construction. By 2035, nuclear capacity could exceed 150 GW.

Market Structure

Regulator: National Energy Administration (NEA), National Development and Reform Commission (NDRC)

Market Model: State-controlled with provincial dispatch. Pilot spot markets operating in several provinces. State Grid and China Southern Grid operate transmission.

Grid Operators:

  • State Grid Corporation of China (covers most of country)
  • China Southern Power Grid (southern provinces)

Major Generators:

  • China Huaneng, China Datang, China Huadian, State Power Investment Corporation, China Energy Investment

Clean Energy Policy

Carbon Neutrality Target2060
Peak EmissionsBefore 2030
Renewables Target50% of capacity by 2025 (achieved)
Nuclear Target70 GW by 2025, 150+ GW by 2035

EAC Infrastructure

Primary Systems:

  • GEC (Green Electricity Certificate): Domestic certificate system
  • I-REC: International system, issued by some generators
AttributeDetails
GEC OperatorChina Renewable Energy Engineering Institute
Standard1 GEC = 1 MWh
ScopeRenewables (subsidized and unsubsidized)
TradingBeijing/Guangzhou power exchanges

Important for SSS: Chinese nuclear is not included in GEC system. Nuclear generation flows to grid as default delivered power, potentially SSS-eligible.
