1
Q
What is a Techno-economic assessment?
A
A combination of technical &(or) economic performance assessment and analyses of processes and systems
2
Q
Examples of motivations for doing a techno-economic assessment?
A
- Lowe capital cost design, for the same design objective
- Incremental production increase, from the same asset base.
- Marginally-reduced unit production costs.
- Better energy/environmental performance, without compromising competitive position.
3
Q
What is the levelized cost of energy (LCOE)?
A
The LCOE averages the cost of producing energy for a generation plant across the whole life cycle for this plant:
LCOE=(total life cycle cost of the generation plant) / (total energy produced be the plant over its lifetime)
4
Q
What is included in the total life cycle cost of a plant?
A
- Capital cost of deployment
- fixed operations and maintenance costs per year (not proportional to the actual or estimated power output of the plant)
- Variable operations and maintence costs (proportional to the actual or estimated power output of the plant)
- Fuel costs
- Cost at end-of-life disposal or salvage benefits.
5
Q
Mention some cost affecting parameters
A
- Production facility investment
- Production facility O&M
- Fuel prices
- Raw material prices
- Production Efficiency
- System losses
- Taxes and VAT¨
- Financial support/grants
- Utility prices
6
Q
How differs TEA from LCOE?
A
- LCOE does not account for performance assessment
- More accurate operating hours are estimated
- Calculate capacity factors
- Applicable to more than one plant in a system
- Tool for comparing alternatives
- Robust sensitivity analyses
