There are plans to build up to 60 wind turbines outside Dublin Bay.
The offshore wind farm would be be around 10 kilometres off the coast and cost over €1 billion.
RWE Renewables and Saorgus Energy are to lodge planning permission for the turbines which will be around 300 metres in height early next year.
Those behind the project say: 'Based on preliminary results from environmental and technical studies that we have undertaken, the offshore element of the wind farm could include:
- Between 45 and 61 turbines
- Individual turbine capacities of between 8 megawatts (MW) and 15 MW
- Total project capacity between 600 MW and 900 MW
- Individual turbine tip heights of between approximately 240 metres and 310 metres
They hope the Dublin Array Project will be in operation by 2026, and a public consultation is now open.
