The largest wind project to gain consent in the UK has been approved by the Scottish Executive. Fred Olsen Renewables is to build 52 turbines totalling up to 164 MW next to its operational Crystal Rig wind farm in the Scottish Borders. The existing 50 MW wind farm is already one of the largest onshore in Britain, comprising 20 turbines with an extra five turbines planned for installation this year. The combined output from both phases of the development will be up to 229 MW. It will meet some 1.8% of Scotland's total electricity consumption and around 15% of the Scottish parliament's 2010 renewables target. Construction could begin in 2007, but this depends on gaining a grid connection, says Donald Speirs of Natural Power Consultants who developed the project for Fred Olsen Renewables. The company is in the queue for connection to National Grid's network in Scotland along with many other renewable developers, he says.
