We currently estimate a few of the smaller sources (including oil) from real-time dispatch data which sometimes exaggerates things. Metered data was just published and it was actually just a couple of blips at a couple of tiny oil plants -- not zero, but now it barely shows on our chart.

Increasing domestic solar generation leads to the emergence of duck curves in Ireland

Yes indeed, it's very likely rooftop solar. We were the first report on the "duck curve" in Ireland back when solar really started to take off in the ROI in 2024.

Eyeballing it, this week's dip roughly matches a sunny week in June 2024; if so, great news! 🦆

Think I replied too quick there; eyeballing it, recent duck curves have been *significantly* larger than what we first started seeing in summer 2024! 👀

Yes, looks like a significant amount of both curtailment and constraints. We're planning a feature on dispatch down in the premium edition of our next monthly newsletter, arriving May 1. Favouring imports over domestic renewable generation is exactly the kind of thing we hope to uncover 🔎

Unlikely in our daily reports anytime soon but we're planning a feature on dispatch down in the premium edition of our next monthly newsletter, arriving May 1.
