SSE buys stake in Walney wind farm

Walney Offshore Wind Farm will be built 14 km west of the Isle of Walney in the Irish Sea, with SSE and Dong Energy investing in two 183.6 MW phases, Siemens turbines, and ROC-eligible generation.

Scottish and Southern Energy plc has announced plans to take a 25.1% stake in the 367-megawatt (MW) Walney offshore wind farm, which is being built by Dong Energy in the Irish Sea.

The Walney wind farm is almost ready to start construction and will be situated 14 kilometres west of the Isle of Walney in the Irish Sea as the Cumbrian coast plans progress for offshore wind. Dong Energy, which will oversee the construction, will retain the remaining 74.9% stake. SSE will pay £39 million (US $62.4 million) for its stake, with £17 million of this amount subject to the operational performance of the wind farm. As a shareholder in the project, SSE will pay about £250 million ($400 million) of the construction costs.

The wind farm will cost roughly £1 billion ($1.6 billion) to build and will be constructed in two phases, Walney 1 and 2, each totaling 183.6 MW. Construction of the first phase is scheduled to start this spring. The second phase will begin in the spring of 2011. Commissioning of the wind farm will also take part in two phases during the first half of 2011 and at the end of 2011. Siemens is supplying the wind turbines for the project, and its recent Scottish contract underscores its role, with new 120-metre rotors slated for use in the second phase.

The wind farm will have an average load factor of about 43% and produce approximately 1,300 gigawatt-hours of electricity annually. This level of output will qualify Walney for 2.0 Renewable Obligation Certificates (ROCs) per MWh, under the UK government's Renewables Obligation Scheme as the green goals move forward nationwide.

The addition of the Walney stake takes SSE's portfolio of onshore and offshore wind farms in operation, in construction or with consent for development in the UK and Ireland to more than 2,100 MW, while RWE UK plans highlight broader sector momentum. Dong Energy recently purchased a 50% stake in the 270-MW Lincs offshore wind farm for £50 million ($79.8 million) from Centrica plc.

"SSE is already the UK's leading generator of electricity from renewable sources, with the largest and most diverse portfolio," said Ian Marchant, chief executive of SSE. "The potential for harnessing the energy of the wind off the coast of the UK is vast, and the combination of Walney and Greater Gabbard gives us a very good offshore wind construction portfolio for the next few years. Dong Energy is one of the world's leading offshore wind farm developers, even after the Welsh project cancellation with E.ON, with extensive construction and operational experience."

Anders Eldrup, chief executive of Dong Energy, said: "The partnership with SSE in the UK provides an opportunity for Dong Energy, through its reduced share in Walney, via the Walney stake sale process, to diversify risks, and at the same time utilize and further develop our offshore experience. The UK is one of the primary markets for Dong Energy's wind development activities now and in the near future."

The news comes as Scotland's First Minister Alex Salmond claimed that Scotland could be Europe's leading exporter of renewable energy in the coming decades, a vision aligned with the UK's 2020 renewables target that drives investment. In his New Year's address, Salmond said: "We have perhaps the capacity to produce 10 times Scotland's own electricity requirements and make sure we're the major exporter, the energy powerhouse of the continent."
