Changes to scheduling and dispatch on the grid manifesting here with the appearance of batteries in our morning report for the first time.
As always, we'll be carefully comparing this with the final metered and dispatch data, once available; for now, take this report with a (tiny!) grain of salt 🤞

Renewable generation and discharging storage equalled 35% of yesterday's electricity demand, with a peak of 54% at 23:00. Fossil fuel generation (mostly gas) equalled 45% of demand. 0% of generation was exported, 21% of demand was met by imports.

DHS/ICE used an Olivia Rodrigo song for a video on Instagram and after calling them disgusting, Olivia's team allegedly pulled the song for use on Insta so the video has no background music.
This is the second time she's done this - previously it was a tiktok song.

Every far-right riot and protest that was tolerated, every racist dog whistle from public reps, every bit of hate and misinformation allowed to spread by social media companies, all led to this moment in Drogheda last night where someone felt emboldened enough to try to burn children alive.

Although I really hate when mistakes like this happen, the couple of hours spent debugging usually highlights a bunch of possible improvements to our pipeline 🤷♂️

Sorry folks: SEMO's numbers - published yesterday - show we were a bit off here, with gas and waste-to-energy bottoming out at 1060MW. Low, but far from the current record of 925MW set in September 2023.
Short story: the sources don't always add up to *exactly* 100%, and we're always improving! 🙋♂️🙋♀️

During the recent prolonged dunkelflaute we saw some of the worst days for renewable generation in recent years.
Well, it's over! We believe carbon-emitting sources reached a new all-time *low* this morning of 899MW. We haven't seen a new record in this category for over two years.

*mentally steels himself for this to get literally no wider attention until, say, June 2026 when the Irish EPA (or a similar organisation - who do great work, but at very different speeds than we're used to) put out a press release* 🤷♂️

Even in a month full of notable highs and lows, one stood out: during September, the Irish grid emitted its least amount of CO₂ in a single month in modern times.
Our estimate is 577k tonnes. A lot but, as the chart below shows, just a few years ago we were seeing months with almost *1.4M tonnes*.`

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.

Well I certainly didn't expect solar output record to be broken on September Equinox in Ireland!
🚨 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!

🚨 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 🔋⛰️

Same. I'm grateful I had the options I had. Not everybody is so lucky and I don't for a moment begrudge the ones who had to take a different route.
I went abroad, did everything "right", and ultimately got citizenship in my adopted country. It took years, and was SO MUCH paperwork.
I absolutely DO. NOT. CARE. that some people didn't do the same, and think every single person should have some sort of path to citizenship, wherever they are.
