REC ASA - REC acquires 20% of US downstream player

Oslo, April 11, 2008: Renewable Energy Corporation ASA (REC) has made
a US$ 40 million investment taking a 20% equity position in
Mainstream Energy, a leading US player in PV systems integration and
distribution.

Mainstream Energy LLC (MSE) is well established as a leading PV
systems integrator and distribution company in the US. MSE serves
different customer segments through its operating companies, AEE
Solar Inc. and REC Solar Inc. (the latter not to be confused with the
division within the REC Group with the same name). MSE expects sales
revenues in 2008 of approx. US$ 160 mill.

The investment made by REC to acquire 20% of the shares in MSE totals
approx. US$ 40 million. The initial shareholding of 20% is obtained
through a combination of share purchase and share subscription. Under
the agreement between REC and the current shareholders of MSE, REC
can increase its shareholding to a majority position through options
that can be exercised over the next 3 years. The specific terms and
conditions in any subsequent transactions are dependent on the future
performance of MSE.

"Our investment in Mainstream Energy is both a reflection of the
increasing importance of the US market and our ambition to take a
more active role in building robust and scalable market channels as a
basis for further growth", says Erik Thorsen, President and CEO of
REC.

REC Solar, established in 1997 in California, has grown on the
strength of its professional sales-and-installation teams and strong
marketing partnerships to become one of the largest PV system
integrators of solar electric systems to homeowners and businesses in
the United States. Currently operating in a dozen locations in
California, Colorado, New Jersey, Hawaii and Oregon, REC Solar is
expanding throughout the US.

AEE Solar Inc. is one of the largest distributors of renewable energy
systems and equipment in the US. Headquartered in Northern California
with sales offices in Southern California, Arizona, Utah, Colorado,
and Canada, AEE Solar is a full-service distributor, offering a
comprehensive range of solar products and services. AEE Solar offers
extensive customer service and technical support.

The US market for PV systems has experienced significant growth over
the last years with California taking a leading role with close to
60% of the total US market. Incentive systems and renewable portfolio
standards, both at federal and state level, combined with
increasingly more competitive PV systems, are expected to result in
continued market growth in the US.

The US market in general, and Southern California in particular, are
also believed to be amongst the first markets where PV systems are
going to be able to compete at purely commercial terms, without
subsidies.

"The investment by the REC Group brings not only capital to
accelerate our expansion nationwide, but also deep insight and
experience in the entire PV value chain which we hope to leverage to
provide additional value to our customers and manufacturing partners
alike", says Timothy Ball, Chairman of Mainstream Energy.

Proximity to the customers and insight into local conditions,
including tariff schemes and regulations for installations, are key
to provide cost efficient solution. MSE's leading market position, in
particular in California, and the competencies and capabilities in
design and installation of PV systems provides a robust platform for
future growth. REC will provide added visibility in module supply and
future cost position. Together, REC and MSE will pursue new product
development opportunities and develop innovative solutions aligned
with customer requirements.
