How storms and extreme events affect the electricity supply
The increase in extreme weather events is putting power grids in many countries, including Spain, to the test. Intense storms, floods or strong gusts of wind can cause damage to electrical infrastructure and power outages in certain areas.
When incidents occur on the network, electricity companies must activate backup systems and carry out urgent repair work to guarantee supply. These additional costs can end up having an indirect impact on the electrical system and the price of energy.
In addition, extreme weather events also affect renewable production. The lack of wind, droughts or heat waves reduce the performance of some technologies, forcing the use of more expensive energies such as natural gas to meet demand.
