China
Overview
| Attribute | Value |
|---|---|
| SSS Relevance | ⭐⭐⭐ High (regional) |
| Market Type | State-controlled with partial reform |
| Key Clean Resources | Hydro (13%), Nuclear (5%), Wind/Solar (18-23%) |
| EAC System | GEC (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 Type | Capacity/Output | SSS 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
| Policy | Status |
|---|---|
| Carbon Neutrality Target | 2060 |
| Peak Emissions | Before 2030 |
| Renewables Target | 50% of capacity by 2025 (achieved) |
| Nuclear Target | 70 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
| Attribute | Details |
|---|---|
| GEC Operator | China Renewable Energy Engineering Institute |
| Standard | 1 GEC = 1 MWh |
| Scope | Renewables (subsidized and unsubsidized) |
| Trading | Beijing/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.
Emissions Factors
| Source | Value | Use Case |
|---|---|---|
| National Grid Average | ~550-600 gCO2/kWh | Location-based Scope 2 |
| Regional Factors | Vary significantly by province | More precise reporting |
| Residual Mix | Not formally published | Emerging methodology |
