I don't think we've posted a map of *all* generation before, i.e. one including fossil fuels. I made this one offset some markers slightly so that none overlap -- I think it highlights the wind/solar/gas regions pretty well? 🧪

April 29 was a beautiful all over Ireland, but how did the grid do? Solar farms produced 9.2GWh — meeting 8.5% of the island's demand. However, strong winds and high imports led to grid bottlenecks and ~18% was lost to curtailment. In Antrim, this reached as high as 40%. Side-by-side below 📊 🔎

Good news! The final ENTSO-E report into the Spain blackout is out A complex stew of different factors, but "too much solar" is simply not even among them, let alone a major component. As always: the narrative built by fossil/nuke advocates was wrong www.entsoe.eu/news/2026/03...

Summary
The final report of the Expert Panel on the 28 April 2025 blackout in continental Spain and Portugal identifies the causes of the blackout and outlines recommendations to strengthen the resilience of Europe’s interconnected electricity system. It was prepared by a technical Expert Panel of 49 members, including representatives from Transmission System Operators (TSOs), Regional Coordination Centres (RCCs), ACER and National Regulatory Authorities (NRAs), and was chaired by experts from two unaffected TSOs.

The investigation concludes that the blackout resulted from a combination of many interacting factors, including oscillations, gaps in voltage and reactive power control, differences in voltage regulation practices, rapid output reductions and generator disconnections in Spain, and uneven stabilisation capabilities. These factors led to fast increases of voltage and cascading generation disconnections in Spain, resulting in the blackout in continental Spain and Portugal.

Based on these findings, the Expert Panel sets out recommendations addressing each of the factors identified in the report to help prevent similar events in the future. These include strengthened operational practices, improved monitoring of system behaviour and closer coordination and data exchange among power system actors. The findings of the investigation also underscore the need for regulatory frameworks to adapt in order to support the evolving nature of the power system.

The 28 April blackout was a first of its kind event, and the recommendations aim to strengthen system resilience with solutions that are already technologically deployable. This blackout highlights how developments at the local level can have system-wide implications and underlines the importance of maintaining strong links between local and European system behaviour and coordination, while ensuring that market…

We've spent the New Year selecting 10 takeaways that best represent the key changes and trends affecting the Irish electricity grid in 2025. Key takeaways 1-3: flatlining renewables to demand ratio, increasing imports via interconnectors, and wind dispatch down. (1/3)

A Year in Review: the Irish Grid in 2025 by Green Collective

Swipe to read key takeaways

Key Takeaway #1: Across the island of Ireland, the ratio of renewable generation to demand continued to flatline in 2025: renewable generation equalled 38.4% of demand, compared to 37.5% in 2024, 38.3% in 2023, and 37.3% in 2022. (1/10)

Key Takeaway #2: Greenlink, the third and newest interconnector between Ireland and GB, entered full operation in early 2025. As a result, net imports via interconnectors reached 14.6% of demand in 2025, up from 11.7% in 2024. (2/10)

Key Takeaway #3: Across the island, transmission constraints were the main reason for dispatch down (DD) of wind. In 2025, the wind DD rate in ROI was 11.3%: 4.7% due to curtailment and 6.6% due to constraints. In NI, wind DD rate was 21.7%: 3.2% due to curtailment and 18.5% due to constraints. (3/10)

Why revamp the county rankings? Treating wind and solar separately, things just don't vary that much month-to-month -- new plants being few and far between. However, renewables as a *whole* varies a lot throughout the year, e.g. solar in summer and hydro in winter. Should be much more interesting!

It seems transmission constraints on the grid were notably lower than usual, perhaps due to extremely low winds.
