Heatwaves can create an excessive strain on electric networks when people need electricity the most. An increase in demand for cooling coincides with reduced efficiency of power generation, transmission and use of equipment.
Why does heat stress the grid?
One of the reasons why heat is a problem for power grids supply systems is that when temperatures go up, they increase the demand for electricity and cause problems for the systems during peak hours.The IEA has highlighted the growing importance of stronger and more flexible electricity systems.
What could go completely wrong?
There are many potential problems associated with the strain on the systems. Overloaded devices, lowered generation efficiency and dangers of wildfires can lead to blackouts.The WHO also notes that heat can make urban power systems more vulnerable.
How can grids prepare?
Systems can get more resilient thanks to energy storage capabilities, demand management and good infrastructure.
