Marubeni Corporation has entered into an agreement with DONG Energy whereby
Marubeni acquires a 49.9% stake in the 172MW Gunfleet Sands offshore wind farm.

Marubeni will pay to DONG Energy a cash consideration of approx. GBP 200
million for the 49.9% stake in Gunfleet Sands. Completion of the transaction is
conditional on, inter alia, Marubeni obtaining financing commitments from
project financing banks. Completion is expected to take place during Q4 2011.

”We are delighted to have reached an agreement with DONG Energy for this
important partnership; it is especially significant as it is the first
investment by a Japanese company into an offshore wind power project. We are
paying close attention to the offshore wind power sector and DONG Energy, the
world leading company in this sector. We believe the offshore wind power sector
represents a tremendous growth opportunity not only in Europe but in Japan and
the Americas as well.” says Masumi Kakinoki, Executive Officer of Marubeni.

"We see this partnership with a well-established and prominent Japanese company
as a vote of confidence to renewable energy in general and DONG Energy in
particular. We believe the further development of the offshore wind industry
will be based on bringing together different kinds of investors with an
interest in this field. We are proud of being recognized internationally as an
attractive partner and a market leader within offshore wind," says Anders
Eldrup, CEO of DONG Energy.

The wind farm, located in the Thames Estuary off the Essex coast, produces
green power corresponding to the annual power consumption of some 125,000
British households. The first green power from the wind farm was produced in
August 2009, and the entire wind farm went into production in the spring of
2010.

DONG Energy will be providing operation and maintenance services to Gunfleet
Sands under a long-term arrangement. DONG Energy and Marubeni have also agreed
a long-term purchase agreement for the power production and green certificates
arising from Marubeni's share of Gunfleet Sands' wind farm.

The transmission assets have been sold as part of the general tender process
initiated by the UK regulator, Ofgem.

The information provided in this announcement does not change DONG Energy's
previous financial guidance for the 2011 financial year or the announced
expected investment level.
