This metrics answers the question how efficient the system is. Aspects of energy convertors, local/on-borad storage, retail and depot, transport of the fuel and production of fuel are are studied based on following.
- Part load efficiency of technology
- Full load efficiency of technology
- Efficiency of auxiliary facilities
The various submetrics are given below.
