The reasons for a brilliant STE future
1. Technical STE is the only dispatchable and grid-friendly -enhancing grid stability- renewable technology with potential enough to meet the electricity needs worldwide in order to achieve a carbon free generation system
2. Local Economic Development Local content of STE plants -and corresponding contribution to the GDP- will be one of the main drivers behind the supporting policies in many countries.
3. Competitiveness The cost of STE plants will show important reductions when approaching from the current 3 GW installed to the similar values of Wind (300 GW) and PV (100 GW)

The consulting firm Deloitte carried out the study “Macroeconomic impact in 2010 of the Solar Thermal Electricity Industry in Spain”, which can be downloaded from www.protermosolar.com In the 2010 study the basic element for calculating the impact on the GDP and on the other economic aspects was the number of plants under construction or operation along the different months of 2010. When calculating the impact in 2012 we have used the same ratios to all power plant under construction or in operation, along with another set of consistent hypotheses in line with those used by Deloitte in 2010.

Actual PPA for a given project at a certain location under specific
support circumstances
Harmonized PPA for a “typical” project at
the same location without public
support
“Discount” factors
PPA or FiT duration
Concessional loans
Specific Financial conditions
Plant size
PPA escalation rate
Loan duration
Grants
DISCLAIMER: This attempt to provide reference prices must be considered approximated. There are many default values that might be not applicable to all projects as well as some country specific requirements.
“Typical” project 150 MW 4h storage 25 PPA No public financing and no escalation

Cost reduction estimations: The view from the Industry in 2012
Hypothesis: 30 GW will be built at that time. Some breakthroughs might accelerate this trend.
