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.

Great news! Congrats!

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

Anyone who watches the UK version knows that every fucking series theres a blond girl who gets really overemotional whenever they get accused and then end up cosying up to a male traitor and protecting them right to the end #TraitorsIrl

Mentions of “alpha male” and “we can control her”. Oof so many exhibits!

Gonna need a 1500 word thinkpiece on the gender dynamics going on in Slane Castle. They talk around it a lot on Uncloaked but why do we think Katelyn was put in the role of mediator between two aggro lads, why is Oyin underestimated, and why do Nick and Ben think they run the castle #traitorsirl

I am particularly gagged by his audacity to label his company page (yes, he is posting on LinkedIn as well) as "Renewable Energy Power Generation."

TIL this guy, who posted this message when we announced @greencollective.io's move from X to here, recently started a bot on X posting daily updates on electricity usage/generation in Ireland 🙃

(Fairly sure it's the same dude I blocked, who had 4 bsky usernames to be annoying in my replies in Dec)
A screenshot of a reply from November 9, 2024 on X in response to Green Collective/Irish Energy Bot's move to Bluesky, from Murtag (@HydCEng): "So long and thanks for all the fish. I hope you get lots of robust engagement over there on your journey toward net zero Neverland. I'll follow you over there (and your green party friends) when you start to appreciate the need for nuclear power or pumped storage for Ireland."

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.

Child labour was deployed to medicate all fourteen geese on three consecutive days, with weight-calibrated doses.

Thank you to @feiwang.bsky.social for the weighing and recording help!

After seeing this excellent chart from the folks at @data.ft.com, we had to see how things look across the water.

Irish solar in 2025 has already overtaken 2024 as of the second half of July, and it looks likely to exceed 1TWh later this year for the first time ☀️

It definitely feels important to include the fact that Norway specifically is uniquely and disproportionately responsible for the nordic heatwave here, because we profit wildly from supplying the cause of the substance causing these deaths, injuries and environmental catastrophes

EirGrid's continued tacit conflation of 1-min/15-min data is a real pet peeve of mine. Be consistent or -- better yet -- publish the highest resolution data (trust me, we can handle it 🤣).

(@greencollective.io used to monitor some regions of the US where 5-min is the norm; 15-min seems so quaint!)

Folks may have seen articles referencing a new solar record in July.

For anyone wondering why the figure (798MW) doesn't match that on our website (864MW):
- we use all-island figures, 798MW is ROI-only
- 798MW is based on "1-minute data" which EirGrid doesn't release publicly

We need an FAQ! 😆

As a long-time FT Weekend reader, it was a real treat to have the newspaper reach out to *us* at @greencollective.io for data to support this article which goes deep on datacentres' continued use of fossil fuels 🏭

Seeing our company name in today's edition was definitely a moment to savour ☺️
