Ronan Group Renewables was one of the pioneers in seeing the potential in offshore wind.

n 1999 Conor Ronan Offshore wind, through Hazelshore Ltd sought and received licences to develop Irelands largest offshore wind farm on the Codling Bank on the East coast of Ireland. 

“With capital expenditure to exceed €3 billion, the Codling project will represent by far the single greatest amount of FDI Ireland has ever attracted.” said Conor. 

The Codling project is a milestone in the development of Offshore wind in Ireland. 

The Codling Project 

  • Number of Turbines – 139
  • Total Nominal Power – 2.1 GW
  • Depth – 12m
  • Distance from shore – 15km

Conor Ronan Offshore wind retains an equity share in the project. See details here.

The West Coast

The West coast of Ireland has the best wind speeds in the world. The technology for floating off shore wind has developed more rapidly than anticipated opening up the West coast of Ireland for unprecedented development.

Utilisation of floating foundations offer increased flexibility for the siting of turbines, enabling access to locations previously inaccessible due to depth constraints. This gives it a key advantage for accessing areas of higher average wind speeds at optimal spacing, leading to increased yield and capacity factors at a competitive LCOE.

Marine Renewables Industry Association Submission to Public Consultation

Development of a National security strategy

It is widely accepted by the global industry that Ireland is one of the World’s best places for offshore wind:

  • High wind speeds, average 10.2m/s, and > 9.5m/s in many regions
  • Large potential > 5GW
  • High full load hours: with floating wind to exceed 50%
  • Floating sites: More potential for cost reduction and less visual impact

70/30 Action Plan

The key driver for Irish offshore renewable energy is the recently adopted Climate Action Plan 2019 which has set a target of 70% of our electricity generation coming from renewable sources by 2030.

This is a remarkably ambitious target – no country has achieved anything close to RES-E of 70% with plans to move to a Zero carbon economy by 2050.

Killybegs Harbour


Ronan Renewable Group has invested in Port facilities at Killybegs, the best deep water port on the wind rich north west coast, and aims to grow alongside the industry as it develops floating wind resources off Irelands west coats.

Working with industry stakeholders the group is developing the facilities and services necessary for an Operations and Maintenance base for the floating off shore industry.

  • Pier Access
  • Ships Agency
  • Stevedoring
  • Set down storage
  • Warehousing

Coupled with the marine engineering excellence of the port which has serviced the oil and gas developments off the west coast as well as Irelands main fishing fleet Ronan Group Renewables is committed to the long term and strategic development of the port to service the off shore floating wind turbines off the North West Coast.
