The largest steam turbine modernisation programme in the UK is moving rapidly towards completion at Drax Power Station in Selby, as the final Siemens-built turbine rotor blade components were delivered to site this week. On completion, the project will enable Drax to reduce emissions of carbon dioxide (CO2) by one million tonnes a year, equivalent to taking 275,000 cars off the road.
The £100 million contract to replace the low pressure and high pressure turbines on all six generating units at the power station was signed in 2007 between Drax Power Limited (“Drax”) and Siemens. The contract set in motion the manufacturing of 28 separate turbine rotors weighing over 2,800 tonnes and over 80,000 individualised turbine blades, which, laid end-to-end would stretch the distance of a marathon. The contract also secured the establishment of a global supply chain and a six-year installation initiative, as well as forging a unique, industry-leading relationship between the two companies. Together, this complex undertaking will help Drax increase its overall efficiency to almost 40%, reinforcing its position as the most efficient coal-fired power station in the UK.
The international project has seen commitment, cooperation and hard work from Drax, the Siemens service teams in Newcastle and in Mulheim an der Ruhr, Germany. The combined team effort over the past four years has enabled the project to move forward smoothly to final delivery this year.
Peter Emery, production director at Drax said: “The relationship we have with Siemens has gone from strength to strength. Together we are working towards one goal and we are proud to have achieved so much together.
“Through increasing the overall efficiency of the electricity generation process, the new turbines make a meaningful reduction in our carbon footprint. This, along with the fantastic working relationship we have built with Siemens, is definitely something to celebrate.”
Darren Davidson, head of projects at Siemens Energy Service UK in Newcastle, said: “Drax was keen to take a long-term view of operations with the integrity of the turbines in mind, as well as improving the efficiency of the power station and reducing carbon emissions. We met Drax’ requirements in each of these areas and worked closely together as a team from start to finish. We were able to bring to light issues relating to the sustainability of the plant, and then suggest ways in which this could be achieved from design through to installation, and beyond. We look forward to continuing to support Drax on future projects”
Jürgen Bahr, the lead for the Drax project at Siemens Mulheim since November 2009, said: “over the last two years, each unit has been delivered successfully and on schedule. The whole team has demonstrated excellence throughout the project. We have to thank the team at Drax and our colleagues in Newcastle for their cooperative approach.”
