Partnering with Ørsted to deliver the Tonn Nua offshore wind farm

In partnership with Ørsted, we were provisionally awarded the rights to develop the Tonn Nua site off the coast of County Waterford by The Department of Climate, Energy and the Environment (DCEE).

Currently in an early phase of development, once completed the site will span 306 square kilometres with expected capacity output of approximately 900MW, enough energy to power almost one million homes based on the wind prevalence in the area.

Oweninny Power Wind Farm - located in Bellacorick, Co Mayo -is owned by Oweninny Power DAC, a 50:50 joint venture project between ESB and Bord na Móna. Completed  over two phases, the wind farm has the capacity to export 172 Megawatts (MW) of renewable electricity which is enough to power approximately 100,000 homes, farms and businesses. Also on site is a Visitor Centre which provides insight to the history of power generation, peat production, ecological interests and the social history of the area. 

Developing and acquiring 1.2 GW of solar energy by 2030

Solar is increasingly central to our net zero energy ambitions. We aim to develop and acquire 1.2 GW of solar by 2030 and continue to develop our growing solar energy portfolio, partnering with others to help deliver this.

Our hydrogen ambitions

We believe hydrogen produced from renewable electricity will play a critical role in the decarbonisation of many sectors. We plan to use our existing capabilities and future renewable growth to become a leading player in large scale renewable hydrogen production, thereby enabling renewable electricity, in the form of electrons or green modules, to meet the energy requirements of Ireland’s future zero carbon economy.
