Engineers were warning the grid was close to crashing due to excess solar
The mass blackouts in Spain and Portugal wrecked havoc on April 28 last year. At the time everyone accountable was feigning confusion, blaming it on a “rare atmospheric phenomenon” which might have set up mysterious oscillations in the line. They were bandying around terms like “ ‘induced atmospheric vibration’ and talking about extreme temperatures (you know, like 23 degrees C). But all along, the head honchos at Red Electrica knew it was due to an excess of solar power and a lack of reliable generation, because the technical staff had told them what was coming:

he cause of the high temperatures around March 20, 2026, was a heat dome, the likes of which occur in the Midwestern United States every few decades. Looking at the temperatures in Phoenix, Arizona, one finds:
-
-
The 105°F maximum temperature from March 19 to 21 is 5°F above previous maximums for this period, but only 1°F above the 104°F that occurred in early April 1989.
-
The highest temperature ever recorded in Phoenix was 122°F during the heat dome of late June 1990.
For some days, the record highs are over 100 years old (Jan 18; June 11 and 12; July 2, 3, 6, and 23; Aug 6; Sept 8 and 23). The highest May temperatures were recorded in 1910.
-
The warmest year in Phoenix was 1934, the first year of the Dust Bowl era. Some of the temperature records for several states that still stand today originate from this year and the following two.

Conclusion
A heat dome is a weather phenomenon that has led to record temperatures in the Western USA multiple times before. Record temperatures in many U.S. states still date back to the period between 1934 and 1936, even though the urban heat island effect has increased significantly since then and amounts to up to 5°C for Phoenix, Arizona, for example. Media reporting on the heat in March 2026 is alarmist because it fails to mention these facts.
