Power Stations: Floods

Volume 464: debated on Monday 8 October 2007

To ask the Secretary of State for Communities and Local Government whether the provisions of the new PPS25 on development on flood plains apply to the development of power generation infrastructure, including electricity sub-stations. (156517)

Yes. Power generation infrastructure, including electricity sub-stations is included in PPS25, table D2 Flood Risk Vulnerability Classification. They are defined as ‘essential infrastructure’ as it is acknowledged that power stations and grid and primary substations may need to be located in flood risk areas. This is because power stations often need a ready supply of water and sub-stations need to be located near to the communities they supply. The PPS25 sequential test will ensure that they are located in low risk areas where possible, but where there are no alternative lower risk locations for this type of development then the exception test will ensure that they are safe.

Recent flood events during the summer have highlighted the importance of essential infrastructure being protected during flood events and PPS25 aims to ensure that any new electricity infrastructure that is essential in areas at risk of flooding is designed and constructed to be operational during floods.
