Introduction
Analysis of the Standard Core Framework
| Evaluation Dimensions | Technology Maturity Evaluation | Economic Evaluation |
|---|---|---|
| Evaluation Object | Key Technology Elements (CTE) | Overall Economic Benefit of the Project |
| Core Indicators | TRL1-9 Level | EIRR/ENPV/FIRR |
| Method System | Checklist Method + Expert Review | Cash Flow Analysis |
Technology Maturity Level 9 Evaluation System
The standard divides technology maturity into three major development stages:
- R&D stage (TRL1-5): from basic principle discovery to simulated environment verification
- Engineering demonstration (TRL6-7): from prototype to engineering prototype verification
- Commercial application (TRL8-9): from offshore testing to commercial operation
Wave energy power generation deviceTypical verification path:
- TRL4: laboratory water tank test
- TRL6: offshore simulated environment test
- TRL8: continuous operation assessment in real sea conditions
Key technology identification method
| Criticality classification | Technical importance | Technical difficulty |
|---|---|---|
| Class A (major) | Class I (very important) | Class I (very difficult) |
| Class B (key) | Class II (important) | Class II (difficult) |
Systematically identify CTE through the Work Breakdown Structure (WBS) and Technical Breakdown Structure (TBS)
Key points for implementing economic evaluation
Core formula for national economic evaluation
Calculation of electricity sales revenue: $$B_s = E_e(1-\eta_{ap})(1-\eta_{tl})P$$
Economic internal rate of return determination: $$EIRR \geq i_s$$
Key indicators of financial evaluation
- Financial net present value (FNPV) ≥ 0
- Payback period ≤ industry benchmark
- Appropriate debt-to-asset ratio
Recommendations for standard implementation
- Technical evaluation priority: TRL assessment should be completed before economic analysis
- Dynamic adjustment mechanism: It is recommended to update the evaluation parameters every two years
- Risk prevention and control: Focus on the risk of technological leap from TRL5 to 6
