Multiple outlets report that the UK came close to a heatwave-related power outage on June 23. The claim is linked to concerns about grid resilience during extreme temperatures and references a major blackout in Spain and Portugal in 2025, when train services stop and industrial activity was suspended. According to the reporting, attention is now focused on how preparedness and risk assessments were handled around the June 23 period, including allegations that relevant information may not have been fully disclosed.
The coverage also discusses the role of a “little-known” government-linked body connected to the energy transition. In the account, the entity is described as having a single shareholder, Ed Miliband, and is the subject of criticism over what it did or did not communicate regarding the severity of the June 23 risk.
Overall, the reporting centers on the same timeline—June 23—and the same alleged outcome: the UK avoided a catastrophic blackout under heatwave conditions. The dispute focuses on transparency and decision-making rather than whether the June 23 event occurred as described.
