DONG Energy temporarily brings two power station units back into service

DONG Energy has today decided to temporarily bring back into service Unit 4 at Studstrup Power Station and Unit 5 at Asnæs Power Station with effect from 9 December 2010 and 3 January 2011 respectively. At the same time, Unit 2 at Asnæs Power Station will be taken out of operation on 3 January 2011. It is DONG Energy's intention to take the two power station units out of operation again on 1 April 2011 and 1 May 2011 respectively and to recommence generation at Unit 2 at Asnæs Power Station on 1 May 2011. Cold weather, coupled with low water levels, in the reservoirs that supply the Norwegian hydroelectric plants has created great demand for generating capacity in the Nordic energy market. At the same time, the cold winter is putting pressure on supply of heat in Aarhus and the neighbouring municipalities. By bringing Unit 5 at Asnæs Power Station and Unit 4 at Studstrup Power Station back into service, DONG Energy will thus be contributing to securing the electricity supply and the heat supply. Unit 4 at Studstrup Power Station and Unit 5 at Asnæs Power Station were taken out of operation on 1 April 2010 and 1 June 2010 respectively. Due to the manning at Asnæs Power Station, this station's Units 2 and 5 cannot be in operation simultaneously. The announcement concerning the temporary bringing back into service of Unit 4 at Studstrup Power Station and Unit 5 at Asnæs Power Station and the taking out of service of Unit 2 at Asnæs Power Station has been sent simultaneously to the NordPool energy exchange. The information provided in this announcement will not change DONG Energy's previous financial guidance for the financial year 2010 or the expected investment level.
