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
Capacity: 455MW
Commissioned: 2005
Technology:
1 x Combined Cycle Gas Turbine (CCGT) (2005)
1 x Open Cycle Gas Turbine (OCGT) (1970)
Coolkeeragh sits on the site of a previous oil-fired plant. With a capacity of 455 MW, our station can provide one third of Northern Ireland’s electricity needs and adds to the supply security for the network in the North West region. To ensure we can always generate electricity, the plant can also operate on liquid fuel (low sulphur distillate).
The newer Combined Cycle Gas Turbine (CCGT) has a dry low nitrogen oxide combustion system, which leads to higher energy efficiency and reduced emissions compared to conventional thermal power stations.
We generate the electricity at 16 kV and then increase to a higher 275 kV and 110 kV level through step-up transformers to match the Northern Ireland Electricity (NIE) transmission system requirements. This high voltage electricity is then transferred to outgoing feeder connections in an adjacent switchyard and then through the transmission system to the electricity users.
We believe hydrogen produced from renewable electricity will play a critical role in the decarbonisation of many sectors.
