Ireland's Electricity Simulation

What will Ireland's Electricity mix look like in 2030 assuming

  1. Demand will increase by the amount Eirgrid predict
  2. 2030 will be an hour by hour weather copy of 2023.*
  3. We will build the wind turbines we say we will.
  4. Solar and battery trends keep going as they have for over a decade
  5. The grid can handle the new power sources + demands

The code for this projection is here
* obviously the weather in any hour of the year won't be the same as that hour in 2023. But by copying a year you get to see how wind and solar peak and lull in an accurate way. Combining more years into an average loses the 'what happens if its dark and calm for a week' accuracy of copying one years weather.

At the moment Ireland gets a lot of wind power. But all the white here under the black line is met by fossil fuels and imports. How much white under the demand line will there be in future?

As wind, solar and battery roll out the amount of fossil fuels and imports needed decreases.


To take one example with these trends continuing in June 2030 Wind and Solar cover a lot of the power needs. With Battery holding enough to smooth out gaps 


On a day view of the year you can see solar has started to cover a lot of low wind times.

and by 2033 continuing trend growth of Solar really would start to cover a lot of demand

2034 61.1 34.1 84.8 65.1 5.4 1.9
2035 63.5 47.1 100.0 90.0 5.3 1.2
2036 66.0 64.9 118.0 122.6 5.2 0.5
2037 68.7 89.6 139.3 165.1 4.8 0.1

Predictions of ten plus years are really not to be trusted. But the reduction to 10.6Twh in 2030 from 25Twh is something this government we just elected controls. We make planning and other decisions all the time that decide if we meet these trend increases in demand, solar, wind and batteries. We can decarbonise fast enough to prevent billions in fines in 2030 if we follow this path.

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 




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.
