Elsam. Offshore Wind Turbines. Horns Rev. Annual status report for the environmental monitoring programme 1. January 2004 - 31. December 2004

Abstract

In 2001, the former Ministry of the Environment and Energy granted Elsam A/S and Eltra A.m.b.A. approval to establish a wind farm capable of producing 160 MW of electric power, at Horns Rev, west of Blaevandshuk at the west coast of Jutland. According to the conditions of the approval, Elsam and Eltra were required to monitor the environmental effects of the wind farm by performing monitoring before, during and after construction of the wind farm. The environmental monitoring programme is financed through Public Service Obligation (PSO). Analogue to the Horns Rev wind farm another offshore demonstrational wind farm was established in the Baltic sea south of Lolland by Energi E2 the Nysted 165 MW offshore wind farm. To coordinate the environmental monitoring at the two demonstration wind farms at Nysted and Horns Rev within the framework of the approved budget, the Environmental Group of Danish Offshore Wind Farm Demonstration Projects was set up. The group consists of representatives from the Danish Forest and Nature Agency, the Danish Energy Authority, Elsam and Energi E2. The Environmental Group initiates, monitors and evaluates the environmental programmes continuously with respect to possible improvements and intensifications to ensure that the design of the individual programmes  More>>

According to the conditions of the approval, Elsam and Eltra were required to monitor the environmental effects of the wind farm by performing monitoring before, during and after construction of the wind farm. The environmental monitoring programme is financed through Public Service Obligation (PSO). Analogue to the Horns Rev wind farm another offshore demonstrational wind farm was established in the Baltic sea south of Lolland by Energi E2 the Nysted 165 MW offshore wind farm. To coordinate the environmental monitoring at the two demonstration wind farms at Nysted and Horns Rev within the framework of the approved budget, the Environmental Group of Danish Offshore Wind Farm Demonstration Projects was set up. The group consists of representatives from the Danish Forest and Nature Agency, the Danish Energy Authority, Elsam and Energi E2. The Environmental Group initiates, monitors and evaluates the environmental programmes continuously with respect to possible improvements and intensifications to ensure that the design of the individual programmes is optimal. After evaluation, the monitoring programmes are proposed by the Environmental Group and carried out after final approval by the Danish Energy Authority. The Environmental Group considers if there is reason to adjust the issues and priorities of the programmes based on previous experience or other inputs eg from the international expert panel, IAPEME (International Advisory Panel of Experts on Marine Ecology). IAPEME evaluates the environmental monitoring programmes and makes valuable suggestions and recommendations to the Environmental Group. The programmes have concentrated on the monitoring of possible impacts before, during and after construction to investigate and demonstrate any potential impacts resulting from the construction of the wind farm. This report presents results from 2004, in the second year of monitoring after the construction of the wind farm. For the Horns Rev offshore wind farm, the monitoring comprises: bottom flora and fauna; hard substrate habitat; fish; sandeel; birds; marine mammals (seals and harbour porpoises); socioeconomic and environmental economic effects. Monitoring programmes in 2004: Due to problems with the turbines, Vestas and Elsam decided to dismantle the turbines and bring them to shore to make the necessary adjustments and replacements. Thus, extensive boat traffic and work took place in the wind farm area between June and October 2004. Since these conditions did not resemble what could be considered a normal operational phase the Environmental Group decided to temporarily suspend the bird and harbour porpoise monitoring programmes planned for the second half of 2004. The biological and marine environments have been monitored continuously since the very first EIA survey and throughout the construction period. The monitoring was expected to continue until the end of 2004 in order to cover the post-construction period. This period has been extended until the end of 2005 in order to provide sufficient data from the operational phase, since some 2004 programmes were cut short by the replacement activities. The present report describes the results of the surveys conducted in 2004. (au)}
