THE CURRENT SITUATION

CSP p lants using pa rabolic troughs a re a lready a reliable and demonstratedtechnology. More than 40 plants, with an overall installed power of more thantwo thousand MW, are either in c onstruc tion or in opera tion, ma inly in Spa inand the USA.

Parabolic through c ollec tors and heliosta t fields a re in opera tion sinc e the ea rly

80s with p roven performanc es. CSP plants are dispatchable and their d ispa tchab ility c an be enhanc ed by

new storage technologies and/or hybrid concepts using other renewable orc onventiona l fuels. E.g . ACSs p lants And asol 1 and 2 have a nomina l storagec apac ity of 7.5 h eac h.

Dual applications, i.e. elec tric ity and water desa lina tion, might b ring importantbenefits in some spec ific p lac es.

Currently, the generation costs are still high and the conversion cycle waterneeds for c oo ling need to be red uced

CSP p lants a llow the g rid to a c c ommodate more non d ispa tchab le renewab lesources.

MSP-STE OBJECTIVES 2020

The Sola r Therma l Elec tric ity ind ustry

estimates at 30GW the potential for installedcapacity in the EU by 2020, mostly in theSouthern c ountries.

The potentia l in Med iterranea n Southerncountries is technically several times the

world demand. We can imagine that alower target than for the EU is economicallyviab le, for insta nc e, 20GW.

All over Europe national AC-grid and interconnectors are

saturated

In most European countries the peak power growth was notcompensated by the transport system expansion in the sameamount d uring the last yea rs.

In most EU countries the construction of new overhead

transmission lines is virtua lly impossib le. In the rest o f the c ountries,the required time to build new overhead transmission line is quite

high (between 10 and 15 yea rs).

The European Sup ergrid is the only solution

TRANSMISSION: THE REAL CHALLENGE

HVDC TRANSMISSION LINES:


19/21

There a re many examples in the world of HVDC lines

For overhead lines tension used c an b e up to 800 KV, a t overa ll c ost

comparable with AC lines of the same capacity, while submarineand underground lines a re only up to 350 KV for the time being, andha ve still a higher c ost.

In the next five to ten yea rs, due to the new deve lopments expec ted

in terms of the cable isolation, the main cable and convertingstations suppliers expect to increase voltage with the new transistorstechnology and increase transmission capacity to reach costsc omparab le with AC lines.

The ma in transmission c ompanies and TSOs are still no t enthusiasticabout subterranean HVDC due to cost considerations, and onlywhen the need is extremely urgent, suc h as the Frenc h-SpanishPyrenees c onnec tion, they dec ide to go to this tec hnology.

There a re many fac tors whic h a ffec t the c ost of a HVDC line,overhead , sub terranean or submarine. The p a th a t whic h

transmission cost will decrease is linked to technologicaldeve lopment a nd the size o f the ma rket.

A credible plan to implement a Euro Mediterranean super-grid willencourage investments leading to substantial reduction in cables

and c onverting sta tions fabric a tion a nd dep loyment c osts.

A growing number of new HVDC submarine lines are beinginsta lled or developed a ll a round Europe.

A new European super-TSO will be the first step to c rea te the newplanned supergrid, to be developed under a concession scheme(Brazil is a story of suc c ess).
