The evidence of climate change is becoming apparent in the UK, particularly in the increasing frequency of “extreme” weather events. These events differ significantly from normal patterns, are associated with severe impacts and are historically infrequent. A number of extreme weather events experienced in the last decade in the UK have been attributed to climate change including include floods, heatwaves and droughts.

The effect of these events on electricity system operation is currently unclear. The magnitude of the impact of these events may be exacerbated by factors including aging infrastructure and an increasing reliance on weather-dependent renewable energy sources as we move to a net zero energy system. This may lead to higher operational costs and complexities for system operation.
This project will evaluate the impacts of extreme weather events on system operation up to 2050 and produce a map demonstrating the risks, probabilities, and consequences of such events at a 25km grid level of GB.
