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.

Our Generation Portfolio

North Wall

Feb 24, 2022, 10:30 AM
Title : North Wall
Location : Co. Dublin
Select a choice : Thermal
Latitude : 53.3495760
Longitude : -6.2119940

Fuel: Natural gas and distillate

Capacity: 106 MW

Commissioned: 1949 and 1982

Technology: Open cycle gas turbine (OCGT)

 

North Wall was our first thermal power plant, commissioned in 1949.

In 1982, we converted the station from an oil-fired operation to a combined cycle plant running on gas and distillate, installing two new GE frame 9E gas turbines and a waste heat recovery boiler. This provided a repowered combined cycle gas turbine (CCGT) arrangement and a separate open gas cycle turbine (OCGT).

Overall, this increased North Wall’s output from 51MW to 260MW. It also became the most efficient thermal station in the fleet at the time and led the way for other station conversions to CCGT technology.

In 1997, we installed low nitrogen oxide burners to further reduce our environmental impact - the first ever successful retrofit of this kind of equipment. In 2012, we converted the CCGT arrangement to OCGT and the station now provides 106MW this way. 

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.

Investing in offshore wind energy

Offshore wind is playing a major role globally in our fight against climate change and our transition to a zero carbon economy.

We have been involved in offshore wind since 2017 with a number of planned projects for Ireland and the UK.

Our people working in generation

Meet Joe Shinkwin, Onshore Wind Project Director in our Generation and Trading business. Joe shares how the projects he works on not only deliver clean energy but also create a community benefit fund to support local initiatives. At ESB, we’re investing in renewable energy to help reach net zero emissions, and we’re proud of the people making it happen.
