DONG Energy A/S - Severn Unit 10 Return to Service Update

This is an update of the general service notice about Severn Power Station UNIT
10.

Currently the date for expected return to full commercial operation is
14/03/2012.

From today 06/03/2012 until 14/03/2012 a testing schedule will be followed
which will include periods of normal running and periods when the unit will be
shut down. Therefore, the market should expect various levels of generation due
to the scheduled testing and the potential for further variance should
technical problems be encountered.

Should the return to full commercial operation be delayed or brought forward
DONG Energy will release a new market update with the new date for commercial
operation.
