Following on from yesterday's new all-time high for solar, two charts to illustrate the rapid rise of solar power in Ireland between 2022 and 2026: - peak output on the sunniest days: ~100MW -> ~1400MW - annual production: ~130GWh -> >1500GWh (we project) In both cases, >10x in just 5 years ☀️ 📈

Electricity generation in Ireland over the summer has historically been dominated by fossil fuels. But, that's changing: solar and batteries (along with imports) are gradually displacing gas generation. It won't be long before we see a summer month with mostly renewable generation.

A bold red line representing 2026 begins the year below the mean, just below 26 ºC, and continues to present day far above the mean, 29.4 ºC. Gray gridlines get “pinched” in the middle, representing narrower summer deviations, highlighting that the current temperature is almost 3.5σ above the mean.
