6. 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 reasons for a brilliant STE future

12. 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.
Macroeconomic impact of the
STE Industry in Spain in the year 2012

13. Main results of the
macroeconomic impact in 2012
Installed capacity 1.970 MW
Contribution to the GDP 1.835 millions €
GDP in construction 958 millions €
GDP in O&M 877 millions €
Electricity generated 3.432 GWh
Equivalent premium (CNE) 927 millions €
Employment 17.816 Persons
Employment in construction 15.607 Persons
Employment in O&M 2.209 Persons
I+D investment 60 millions €
CO2 emissions avoided 2,4 t CO2
Savings in CO2 rights 17 millions €
Savings from replacing imported fossil fuels 131 millions €

14. Premiums: 927 M€
Savings in CO2 rights: 17 M€
Savings from replacing
imported fossil fuels: 131 M€
Fiscal contribution
(Social Security, Corporate, Personal
and Local Taxes,) 772 M€
Contribution to GDP:
1835 M€
+ Leadership of the Spanish industry
+ Attraction of foreigner investment
+ Reduction of electricity pool price
+ Regional economical convergence
Comparison between premiums received
and returns to the economy in 2012
Unemployment subsidies
avoided: 132 M€
Supporting STE was a
wise decision for Spain

18. Other direct effects on Industry
Reorientation of other mature industries:
- Construction, civil works
- Engineering of conventional power plants
- Electricity Transmission Infrastructures
- Galvanizers, …
Reinforcement of some industry sectors:
- Piping and tanks
- Heat exchangers
- Boilers
- Cabling
- Telecommunication and control
Enlargement of supplier’s subsidiaries in the country:
(Promotion, Maintenance, Stock Management, …)
Huge impact in auxiliary sectors
- Cleaning, environmentalists, labs, …
- Road transport
- Training, …

19. Jobs in a typical STE plant
in Spain (50 MW, 7,5 h. storage)
 2214 one year equivalent jobs on the whole value chain
(promotion, engineering, comp. manufact.,& construction)
 47 direct jobs for operation and related services during
the whole life span of the plant

Some breakthroughs might
accelerate this trend.
