Benefits to Investors of wind and solar maps

Allows investors to assess energy yield, at scaleof investment needed (and possible returns), ata range of power purchase tariffs, across ageographical area

Allows comparison of the relative economicviability of different locations

Allows identification of priority investmentopportunities

ECONOMIC RESOURCE LOOP EXAMPLE

20/24

CSP economic resource calculation

Capital costs (capex) $6,068/kW

Grid connection costs: $55,000/km

Operational lifetime: 25 years

Nearest electricity grid: 200 ha urban

Others

Straight line depreciation period: 20 years

Income tax rate: 20%

Operating/maintenance costs: 1.2% capex

Discount rate: 8% or 12%

Power purchase tariff USD/MWh: varied

Grid square assumed economically viable at a given tariff /discount rate combination if Net Present Value is positive afteroperational lifetime

Limitations

This method can guide where pre-feasibilitystudy work is likely to be worthwhile

However it does not replace site-specific,technical and economic investigations andcosting
