Isolux Corsan Continues to Lead the Field in PV Plant Construction Worldwide

The Company has Built Plants With a Total Installed Capacity of 267 MWp in Three Years

MADRID, December 16, 2010 - Isolux Corsan reasserts its pole position amongst the leading
specialised companies worldwide in the construction of turnkey projects
(Engineering, Procurement and Construction/ EPC) for photovoltaic solar
plants built primarily in Spain and Italy by achieving an installed power of
267 MWp in only three years.

In a record time of nine months the company, has just
completed the construction of the largest photovoltaic plant in Europe in the
Italian province of Rovigo, with a surface area of 85 hectares and an
installed power of 72 MW.

The facilities, developed by the American company SunEdison
are located in the region of Veneto ( Rovigo/ Italy). It will generate enough
clean electricity to provide for the annual consumption of a population of
50,000 inhabitants and will also save the atmospheric emission of 41,000
tonnes/year of CO2.

280,000 installed modules

Isolux Corsan has made every endeavour, from the perspective
of logistics and human resources, to undertake the construction of this
photovoltaic plant. It has employ a total of 500 people. In addition it has
used a total of 280,000 solar panels based on monocrystalline and
polycrystalline technology, more than 6,000 tonnes of steel structures and
more than 840 kilometres of various types of cabling, e.g. low voltage, high
voltage, fibre optic, etc. were used.

The plant is also fitted with cutting-edge technology for its
remote monitoring and centralised operation and also for anti-intrusion
monitoring and control along the more than 4 kilometres of the perimeter
enclosure.

Other relevant projects

In conjunction with the Rovigo photovoltaic plant, Isolux
Corsan is now finalising other photovoltaic projects in Italy with an output
of 27 MW. Prior to this, it is worth highlighting the 170 MWp installed in
Spain mainly for the company T-Solar one of the leading independent power
producers (IPPs) in the international market for renewable energie . This
includes the Arnedo plant ( Rioja province/ Spain), one of the largest in the
country covering a surface area of 70 hectares and producing an output of
34.19 MWp.

For the forthcoming years, Isolux Corsan is addressing the
challenge of consolidating the internationalisation of this activity abroad
with new projects. Examples of these currently in progress are in France,
Italy and Greece, North Africa (Algeria and Morocco) and USA, as well as in
emerging countries in which the constructor and concessionaire is making
considerable inroads. Such is the case in India, Brazil and Mexico.

Isolux Corsan's activity in developing photovoltaic projects
ranges from administrative processing, engineering and construction through
to the commissioning and maintenance of the facilities for their entire
service life. The management and execution of all work is underpinned by the
main official management certifications for the areas of R&D&I (UNE 166.002),
quality (ISO 9001), environmental management (ISO 14001) and the prevention
of occupational risks (OSHAS 18001).
