Iberdrola, through its subsidiary ScottishPower Renewables, has completed the expansion of Whitelee wind farm in Scotland, a move that will increase the wind farm's capacity to 539MW from 322MW.

According to the company, 69 ECO 100 wind turbines, each with a capacity of 3MW, and 6 ECO 74 turbines, each with a capacity of 1.67MW have been installed at the wind farm, as part of the expansion plan.

France-based establishment Alstom has supplied wind turbines for the Whitelee wind farm.

The wind power facility has the capacity to generate enough clean electricity to power around 300,000 Scottish households, and will lower 840,000 tons of CO2 emissions annually.

During the expansion phase, the wind farm has created around 49 full-time operation and maintenance jobs.

Apart from wind projects, the company is also developing tidal power and wave energy projects in Scotland.

Meanwhile, Iberdrola’s installed capacity in the wind power sector was around 14,000MW, at the end of the first quarter of 2013.
