We are committed to the societal goal of achieving net zero emissions through the generation of renewable electricity
Clare Duffy, our dispatchable generation and storage manager, explains why ESB is investing significantly in large scale battery projects and the role they play in Ireland's net zero energy future.

We have set an ambitious and bold course of action to help Ireland achieve climate action targets and transition the country to reliable, affordable, net zero energy. Green Atlantic @ Moneypoint is a multi-billion Euro programme of significant investments on the County Clare site over the next decade.

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.
We believe hydrogen produced from renewable electricity will play a critical role in the decarbonisation of many sectors.
