Renewable generation and discharging storage equalled 39% of yesterday's electricity demand, with a peak of 68% at 03:45. Fossil fuel generation (mostly gas) equalled 49% of demand. 2% of generation was exported, 13% of demand was met by imports.

The same for journalists. If a politician or business leader spits out 1.5C or net zero, ask them how fast emissions need to drop to reach net zero in 2050, and how fast they are dropping today. Point out the contradiction. Make them explain it.

Yesterday's metered data is out and...the new real-time battery data is looking good!
*Delighted* to finally have batteries in our daily reports: it was the last piece of the puzzle and, hopefully, with this new scheduling and dispatch system, they'll be meeting more and more of demand 🔋

Most of Ireland's uplands are commonage, ie co-owned by local farmers.
The ONLY real income from commonage is via subsidies, almost always for ecosystem-killing sheep. This is why Irish mountains are all empty wastelands, kept that way by your taxes.
Why are we STILL not paying farmers to rewild??

Renewable generation (that's biomass, hydro, wind, and solar) never dipped below 50% of electricity demand yesterday. Overnight, it exceeded 100% for a little while around 1am.
This is still rare outside of the winter: we saw it in Aug/Sep 2023, only in winter in 2024, and now in Aug/Sep 2025.

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.

🚨 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!
