This is a complete list of operational, offshore wind farms in the Irish Sea and connected areas such as the Celtic Sea and North Channel.
This information is gathered from multiple Internet sources, and primarily the 4C Offshore's Global Offshore Wind Farm Map and Database and is current up to February 2015. The name of the Wind Farm is the name used by the Energy Company when referring to the Farm and is usually related to a shoal or the name of the nearest town on shore. The Wind Farm part is implied and hence removed for clarity.
The list is sorted by capacity, but it can be sorted in any way by clicking the symbol >< at the top in each column.

| "Cap." is the rated nameplate capacity of the wind farm "When" is the year when the windfarm was or will be commissioned and put into service. "Cost" is the total capital cost of the project up to commissioning. "Cap. Fac." is the average capacity factor, i.e. the average power generated by the windfarm, as a percentage of its nameplate capacity. "mi to shore" is the average distance of the windfarm to shore, or (where available) the distance from the in-farm transformer/substation to the shore "Depth range (ft)" is the range of minimum to maximum depths of water that the windfarm is sited in "Refs" cite the source references for the information.
