CSP: THE NEXT BIG THING?
So far solar equals photovoltaic, but:
cost per kWh remains stubbornly high
photovoltaic penetration continues to be very small
CSP holds great promise but faces numerous hurdles
various competing and still evolving technologies with thermal storage as key
2
significant potential for reducing costs and advantage in limited space requirement several players already active
US and Spain current market leaders but enormous potential in the Mediterranean

CSP process and components
Working principles and features of CSP a solar reflector field consisting of mirrors
(parabolic shape or flat) concentrates solar
radiation onto a receiver (i.e. absorber tube in
which synthetic oil or an other medium flows, or
a central receiver tower holding the heat transfer
medium)
the heated transfer medium is pumped througha heat exchanger generating steam which drives
a steam turbine to produce electricity
during the cycle, the transfer medium can also
go through a heat exchanger to charge the heat
storage system: molten salt (or another storage
medium) can be heated and used afterwards to
retrieve thermal energy for operation during thenight

Different technologies
are available, at different

CSP plants are usually
large-scale plants (10/50
MW and beyond, up to300 MW), best suited for
utility-scale applications

THERMAL STORAGE IS KEY
Thermal storage allows CSP to supply electricity even when the sun does not shine and
to dispatch energy predictably and on demand, significantly improving plant revenues
Heat is stored in molten salt (or other media) and can be retrieved for operation during the
night: the plant is able to produce electricity for a longer number of hours

storage medium is estimated to reduce additional capex to 20/kWh; ** at Andasol 1 (200 ha in total), thermal storage footprint is 50 ha

CSP: GREAT PERSPECTIVES, WITH SOME SERIOUS HURDLES
PROs CONs
a (partially) mature technology, notwithstanding
still open to many improvements: economies of
scale have not yet been reached
best positioned to exploit the potential offered
by solar energy, several times larger than the
current and future world electricity demands
more cost-effective than solar hotovoltaic and
location specific: high potential in the US, lower
in Europe, enormous in North Africa
not yet cost-competitive with conventional
electricity sources
capital intensive: financing may constitute a
major hurdle in the actual economic downturn
CSP is a viable CO2-free alternative to PV for large-scale infrastructure
7
competitive with other renewables sources scalable and with thermal storage possibility
allowing dispatchable power, i.e. electricity
predictable and on demand(unlike other
renewables): both ofgreat interest for utilities
hybridization potential for deployment together
with traditional technologies or as retrofit to
existing plants
many government incentives already in place
huge pipeline of projects around the world, and
growing: Spain and US are the leaders
huge quantities of water needed for the cooling
process: dry-cooling technologies are underdevelopment, but not mature yet
components bottlenecks possible in the medium
term (i.e. receivers, mirrors, etc..)
typical large-scale deployment reliant on the
development ofintegrated and dedicatedgrids/connections
performance negatively affected by wind and
dust

CSP OFFERS AN ENORMOUS POTENTIAL WITH LIMITED LAND USE
CSP has a limited footprint, far smaller than required by other renewables
9.000.000
Area needed to satisfy the current world electricitydemand through different renewable energy sources
km2
A desert area of 80 km x 80 km dedicated to CSP couldproduce in a year as much energy as contained in all Middle
East oil production (9 billion barrels/year)
World electricity demand* can be met through a desert area
of 300 km x 300 km (as small as 0.23% of all world deserts)

MARKET: TODAY THE U.S. AND SPAIN ARE UNDISPUTED THE LEADERS
After the first plants during the 80s, CSP is coming back, driven by oil price volatility,
climate change concerns, and new incentive schemes
California 1985-1992
9 parabolic trough plants built for a total of 354 MW: the plants
were provided with natural gas back-up (SEGS plants)
Electricity production costs decreased by about 2/3, from 0,44
$/kWh for the first 14 MW plant to 0,17 $/kWh for the last 80
MW plant
Spain 2007-2009 Spain ha set a 500 MW CSP target for 2010, and has approved a 0,27 /kWh 25
years feed in tariff for CSP
Between 2007 and 2009 the first European CSP plants have started operations:
PS10 (11 MW) and PS20 (20 MW), solar tower technology
Andasol 1 (50 MW) and Puertollano (50 MW), parabolic trough technology
PE1 (1,4 MW), the world first linear Fresnel commercial plant
The current pipeline includes at least 12 plants in construction for a total of 800
MW, plus about 2.000 MW near construction, 8.000 in authorization, 3.500announced
USA 2007-2009 In 2007 Nevada Solar One (67 MW, parabolic trough) starts operations, the first CSP
plant built in the U.S. since 1991
CSP development is mainly driven by RPS (Renewable Portfolio Standards), which
oblige utilities to source certain shares of electricity from renewables
More than 5.000 MW are in construction/pipeline

* two hybrid configurations are possible: in SEGS plants a small natural gas component, up to 25% of the total power production, is installed along with the CSP component; in ISCSS plants a smallCSP component is integrated into a traditional gas plant, to produce up to 15% power during peak hours

The deployment of long range electrical interconnections will be required in
order to import electricity from North Africa to Europe

announced the construction of a3.000 km long / 6 GW connection
between the cities of Adrar and
Aachen, for a 2 bil investment

Growth of energy demand in the Mediterranean region:
recent estimates* indicate that by 2030: energy demand in the area will grow by 44% vs. 2005 levels
30% of natural gas demand and 40% of oil demand will be met trough imports
DRIVERS FOR THE GROWTH OF CSP IN THE MEDITERRANEAN REGION
Increasing focus on CO2 emissions reduction, oil price volatility, energy
security and global climate regulations are driving the growth of CSP
CO2 emissions growth in the Mediterranean region:
by 2030 CO2 emissions are estimated to grow by 50% vs. 2005 levels
20-20 2020 emissions and renewables package:
committed EU to reduce GHG emissions to at least 20% below 1990 levels by 2020 and to
increase the share of renewables in energy use to 20% by 2020 makes explicit provisions that green electricity imported from third countries may qualify
for the target
