Batteries in Ireland 2030

I think the same estimates for Battery power storage in Ireland in 2030 are really too low.

I have talked here about how I think SEAI (Sustainable Energy Authority Of Ireland) estimates for Solar underestimates how much solar we will add to the grid by 2030. 

The SEAI estimate here that we will have 1GW of battery storage in 2030 and optimistically 1.8GW (1.7GWh and optimistically 5.94GWh in total) p87 here 

This estimate comes from p100 of Eirgrid's Ten Year Generation Capacity Statement 2023–2032 

We seem to be nearly at that lower level of GWh already 'Cornwall Insight’s SEM Benchmark Power Curve sees “significant battery storage growth”, projecting that short-medium term lithium-ion battery storage capacity, up to 4h duration, will reach 13.5GWh by 2030, up from 2.7GWh in 2025.'

To take one current planned battery system Ballynahone Energy Storage Co. Donegal 'The company expects the project, which would take 12 months to build, would be capable of storing 1 gigawatt hour (GWh) of energy while future projects will be capable of storing up to 8GWh' That one project could by 2030 surpass the current optimistic estimates

There are domestic batteries, including in cars, which at least reduce peak consumption but could also be used to directly help the grid. If my predictions of close to zero wholesale prices at sunny of windy times by 2030 there will be good incentives for batteries that store power then. and the 13.5GWh estimate could be low. Nevermind the 1.7GWh one of SEAI.


In April 2024 there was 731.5 MW of Battery storage. We added at least 150MW since. Let us say the total now is 880MW. The world has had an annual growth rate of 63.6% in battery storage for the last 10 years (p56 Grid-scale battery energy storage systems). 2023 had an increase of 120.8% so the growth rate seems to be increasing. But if the 63% rate kept going for Ireland's battery storage that would be 43GW. Over 30 times Eirgrid's estimates.
