Folks may have spotted more oil in our recent dailies. It seems we've been doing Kilroot a dirty: this large plant in Antrim switched its older units to gas in March 2024. Now our database is updated, will the dailies get cleaner? Maybe not: Moneypoint's oil units have been online since Tuesday 😬

As the treemap chart below shows, Meath's Gallanstown is currently the largest Irish solar farm. Grid limits have been impacting it all summer -- an issue we highlighted way back in our April monthly report -- but in recent weeks it's been regularly reaching its full capacity of ~120MW again.

Renewable generation and pumped storage equalled 25% of yesterday's electricity demand, with a peak of 36% at 12:15. Fossil fuel generation (mostly gas) equalled 53% of demand. 0% of generation was exported, 22% of demand was met by imports.

On Monday, large-scale solar generation in Ireland reached a new high of 934MW; about 19% of the island's electricity demand at the time ☀️ This took us by surprise - it's nearly October! It seems transmission constraints on the grid were notably lower than usual, perhaps due to extremely low winds.

Renewable generation and pumped storage equalled 15% of yesterday's electricity demand, with a peak of 25% at 00:00. Fossil fuel generation (mostly gas) equalled 61% of demand. 0% of generation was exported, 24% of demand was met by imports.

That Ireland's solar generation record was broken yesterday, in September, says great things about the exponential growth of PV.

Renewable generation and pumped storage equalled 16% of yesterday's electricity demand, with a peak of 31% at 00:00. Fossil fuel generation (mostly gas) equalled 58% of demand. 0% of generation was exported, 26% of demand was met by imports.

🚨 A new high for Irish solar today as output exceeds 900MW for the first time, beating the previous high of 864MW set in July. It seems to have peaked at 943MW at 12.45pm, equivalent to approx. 19% of all-island electricity demand at that time ☀️ More to follow!

A windy September so far and we've recently had some of the lowest-ever "amount of fossil fuels burned" days, e.g. Sep 12 with just 24.5GWh. Only 9 days have seen less. It's virtually all gas, so this was also one of the lowest carbon-emitting days, at about 11,500 tonnes CO₂.

A map of last night's battery activity, in case folks are curious where these things are located📍 The big one is "Aghada BESS 2" and it's the newest battery plant in Aghada, Cork, which is also home to a large gas plant (still operating) built originally to serve the former Kinsale Head gas field.

🚨 Batteries reached a new high of 275MW last night, finally breaking the previous record of 266MW set all the way back in January with Cork's Aghada BESS 2 in the lead with about 135MW 🏅 Together with Turlough Hill, storage was meeting about 9% of all-island peak demand at around 6pm 🔋⛰️

We know we don't own the copyright to daily Irish electricity mix charts, but finding out *this guy* in particular is recreating something we've been doing for the last 5 years in the space we've since left... was truly not on our bingo card. 🤷‍♂️
