The premises in Harbour Square will be the base for the offshore wind team in Ireland and directly follows the recent planning application to An Bord Pleanala for the Dublin Array offshore wind farm.

Taoiseach Micheal Martin TD, who met with RWE executives earlier this week to discuss the company’s projects in Ireland, said: “The Government is committed to accelerating the delivery of renewable energy projects, so I welcome RWE Ireland’s ambitious plans for growth.

“It is particularly fitting that RWE’s new office overlooks Dún Laoghaire harbour, as this is where RWE plans to construct the operations base for its proposed Dublin Array wind farm, creating significant local employment and bringing a new phase of maritime economic activity.”

Sven Utermohlen, CEO RWE Offshore Wind. said: “I am delighted to formally open our new offices in Dún Laoghaire.

“We are proud to support Ireland's transition to carbon neutrality.

“With our Dublin Array offshore wind farm in planning, it could play a key role in supporting Ireland to meet its Climate Action Plan.”

RWE has been operational in Ireland since 2016, with offices located in Kilkenny and Dun Laoghaire.

Operational projects across the country include a 10MW wind farm in Dromadda Beg, County Kerry and two battery storage facilities in County Dublin (8.5MW) and County Monaghan (60MW).

RWE has grown from 25 people employed in 2020 to 50 people employed in 2025 doubling its workforce in Ireland.

Michael Lohan, CEO, IDA Ireland said: “On behalf of IDA Ireland, I welcome RWE’s decision to continue to grow its operations in Ireland.

“In our new five year strategy, launched last month, we have identified sustainability as one of the key growth drivers of the economy, so the commitment by RWE to be a long-term energy partner for Ireland during its journey towards carbon neutrality is a timely one. I wish the company every success as it continues to expand its operations in Ireland over the coming years.”

RWE’s strategic projects in Ireland include the development of the Dublin Array offshore wind farm, which RWE is developing in partnership with Irish company Saorgus.

Subject to planning permission being granted and a financial investment decision, construction of the Dublin Array project could begin as early as 2027, with COD expected in 2030.
