Isolux Corsan Will Construct the Largest Electrical Transmission Line in Kenya

MADRID, June 8, 2011 -

- The Project, Under Contract With the Public-Sector Company, Ketraco,
Will Make it Possible to Upload the Output From The Highest-Capacity
Wind-Farm in Africa (300 MW)

- The Company's Backlog Already Includes Several Projects on the African
Continent, Worth Some EUR1 bn.

Isolux Corsan has won the tender for the construction of the
largest high-voltage electrical transmission line in Kenya and one of the
largest in Africa: 428 km long, bearing 400 KV. The EPC contract, signed with
the public-sector Kenya Electricity Transmission Company (Ketraco), under the
auspices of the Kenyan Energy Ministry, is for EUR142m.

When built, the project will enable uploading of the power
output from the wind-farm with the greatest installed capacity throughout the
African continent (300 MW). It is located near to Lake Turkana, and has been
developed by the private-equity company, Lake Turkana Wind Power, with
support from various financial institutions led by the African Development
Bank.

Construction work on the line will begin in the second half of
this year, and will take 23 months. Isolux Corsan is scheduling finalisation
for the end of 2013.

The new high-voltage line will link the town of Loyangalani,
near Lake Turkana, to the town of Suswa, on the outskirts of Nairobi, which
will mean that several geothermal plants located along the route will be able
to upload their output onto it in the future.

The contract signed with Ketraco is the largest EPC contract
that Isolux Corsan has undertaken to date in Africa. It allows the company to
become known in one of the fastest growing economic areas in Africa, within
the framework of a landmark project, namely the highest-capacity wind-farm in
the continent. It will also make it possible for Isolux Corsan to expand its
business activity in the area over the next few years.

The contract signed with Ketraco consolidates Isolux Corsan's
business in Africa, where it already has stable operations in eight
countries: Angola, Algeria, Gabon, Equatorial Guinea, Kenya, Mauritania,
Morocco and Mozambique. Its activity on the African continent contributes 8%
of the company's total revenues. The projects underway in Africa, mainly in
the energy sector, represent a turnover for Isolux Corsan of over EUR1
billion.
