Solar Energy and Battery Storage

Our strategy Driven to Make a Difference: Net Zero by 2040 sets out a clear roadmap to achieve net zero emissions. We are investing in the development of new renewable generation, including onshore and offshore wind and solar, and significantly increasing the amount of renewable generation connected to our electricity networks. 

We are:

  • Delivering more than a fivefold increase in our renewable generation portfolio to 5,000MW.
  • Reducing carbon intensity of our generation fleet from 414 to 140gCO2/kWh by 2030.
  • Decarbonising 63% of our generation output by 2030 and 100% by 2040 (up from c20% now).

Battery Storage

Our aim is to develop a pipeline of projects to deliver large scale batteries, as well as additional flexible enabling technologies. This is crucial to supporting the grid and will facilitate ever more onshore wind, offshore wind and solar onto the electricity system in the coming decades.

Aghada battery plant provides 19MW of fast acting storage

We commissioned a new battery plant at our Aghada site in Co Cork, adding 19MW (38MWh) of fast-acting energy storage to help provide grid stability and deliver more renewables on Ireland’s electricity system. A second battery - also 19MW - is currently under construction.
