AIRTRICITY, the Irish unit of Scottish power utility SCC, said it will start work on a €50m wind-generating plant at Athea in Co Limerick, which will produce 35 mega watts of electricity.
The project will include 16 giant wind turbines and it is due to come into operation by the end of next year.
Yesterday, the company also officially opened a €60m wind farm at Slieve Kirk in Derry generating 27.6 mega watts with 12 turbines. It is also about to start construction on another wind farm 24km away at Glenconway.
The €8m plant will produce 18.6 mega watts with 13 turbines. The wind farms will all contribute to the island-wide electricity network.
Airtricity's renewable energy unit now provides a quarter of the power sold to customers in the Irish market.
There has been a significant increase in the amount of electricity generated from renewable energy sources over the past two decades, according to the Irish Wind Energy Association.
Wind, solar and hydro power has grown from around 5pc in 1990 to 14.8pc. Wind is the main source of renewable energy production, increasing from less than 1pc of total renewable production in 1995 to over 40pc today.
