Abengoa Solar Signs Contract with PG&E to Supply Solar Power in California

* Abengoa Solar signs Power Purchase Agreement with PG&E for a 250-megawatt
concentrating solar power (CSP) project to be built in California, 100 miles
northeast of Los Angeles, near Harper Dry Lake.
* The California Energy Commission is reviewing the Application for
Certification to license the 1,765-acre CSP project.

SAN FRANCISCO--(Business Wire)--
Abengoa Solar announces the signing of a power purchase agreement with Pacific
Gas & Electric (PG&E) to supply the electricity generated by the new solar plant
"Mojave Solar." The project will generate 250 megawatts (MW) of Concentrating
Solar Power (CSP) and is to be located in an unincorporated area of San
Bernardino County, between Barstow and Kramer Junction, approximately nine miles
northwest of Hinkley, and 100 miles northeast of Los Angeles. The project is
expected to bring 1,200 green construction jobs and, when completed,
approximately 80 permanent jobs to this desert area.

Once it starts operating in 2013, it will generate nearly as much electricity as
all of California`s present-day commercial CSP installations combined, enough to
power about 90,000 average homes, and avoid over 431 kilotons per year of
greenhouse gas emissions.

On August 10, 2009, Abengoa Solar filed an Application for Certification with
the California Energy Commission for its Mojave Solar Project. The project has
been deemed data adequate by the CEC and public meetings are anticipated to
begin in December.

Santiago Seage, CEO of Abengoa Solar explained that "Mojave Solar is a project
we have been working on for several years. The permitting and engineering effort
is very advanced and we are very proud to partner with PG&E to make this project
a reality."

The project will be sited on 1,765 acres of private, previously disturbed land
that had been farmed since the 1920s but is now largely fallow. The solar plant
will use significantly less water per acre than was used for agricultural
purposes.

"The location has been carefully chosen and the plant has been specifically
configured to minimize environmental impacts on the desert," said Scott Frier,
COO of Abengoa Solar, Inc.

The spinoff economic benefits, including jobs created, are expected to be
significant near an area that was farmed for alfalfa from the 1920s but was
later largely abandoned.

Mojave Solar Project will contribute to meeting California`s aggressive
Renewable Portfolio Standard, which calls for moving away from fossil fuels to
solar energy and other renewable energy sources that avoid pollution and
greenhouse gas emissions.

We expect to start construction by the end of 2010, subject to financing under
the U.S. economic stimulus legislation.

The Mojave Solar Project will use a similar size and type of Abengoa Solar
parabolic trough technology as the system that will be installed at the Solana
Electrical Generating Station announced in 2008 near Phoenix, Arizona. This is a
highly innovative system that maximizes power production in trough plants.

The plant uses parabolic mirrors that are arranged in long troughs and track the
sun`s movement continually during the day, concentrating the solar radiation
onto a heat-absorbing pipe at the focal point of the mirrors. A heat transfer
fluid circulating inside the pipe reaches temperatures of more than 700 degrees
Fahrenheit. This heat is then used to generate steam that drives a conventional
steam turbine.

In addition to the Mojave Solar Project in California and the Solana Project in
Arizona, Abengoa Solar has seven CSP plants under construction or operation and
others under development. In August 2009, Abengoa Solar announced that it was
selected by Xcel Energy, Colorado`s largest electric utility company, to build a
demonstration parabolic trough concentrating solar power plant at Xcel Energy`s
Cameo coal plant near Grand Junction, Colorado. Abengoa Solar has also used
recently parabolic trough technology to make industrial process heat for a major
food processor to cook snacks in Modesto, CA and for the U.S. Department of
Energy to treat contaminated groundwater in Tuba City, AZ.
