A new wind farm in Co Tyrone will generate enough electricity to power 6,500 homes.
The Cregganconroe wind farm in Pomeroy will require investment of more than £18.3 million by Irish renewable energy company Gaelectric.
Up to 20 construction jobs will be created by the development, which has received planning permission.
Brendan McGrath, chief executive of Gaelectric, said: "We have been working on planning for a range of sites in Tyrone and Antrim for a number of years. The Cregganconroe approval is a further important step for Gaelectric and represents our second planning success in Northern Ireland this year."
The 11.5 megawatt farm will contain five wind turbines.
Mr McGrath added: "Gaelectric plans to continue its high level of investment in Northern Ireland over the coming years. To achieve this we need an efficient planning system that has sufficient resources to deal with the current workload.
"It is critical that Planning Service staff that have built up a level of hard-learned expertise in this specialist area are not now redeployed in the current Northern Ireland civil service reorganisation.
"Policy makers must ensure that renewable energy, which is an indigenous industry, is properly resourced. Only by investing in this area will its green jobs potential be fully realised in a timely manner."
Gaelectric has 25 projects at different stages of development across Ireland. The first wind farm in Roscommon is expected to be commissioned by the end of the year.
