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 🔋

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 🤞

We generally talk about county-level production of wind and solar separately but if we look at county-level production of all renewables (that's wind, solar, biomass, hydro) then Cork has *never* placed lower than #2 since 2019 and has placed #1 *most* of the time since solar ramped up in 2023 📊

Strong winds over the weekend and renewable generation briefly exceeded total electricity demand early Sunday morning. This has happened sporadically since 2021 but it's the first occurrence in an October month; more importantly, this has now occurred *at least once for three consecutive months*.

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. 🏭 🥇

With strong winds and high imports, the island of Ireland saw more renewable generation than fossil fuels in September. Rare, and great when it happens: we estimate CO₂ emissions for the month hit an all-time low. (from our latest "Irish Grid Monthly" -- sign up for free now) #SpeirGorm #EnergySky

SEMO's pipeline seized up over the weekend so this is the best we can do for now. Not a good day for renewables with wind and solar accounting for just 9.1% of the day's demand! Interconnectors worked overtime to supply an impressive 31.9% of demand. Hopefully back to normal tomorrow!

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*.`
