Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government whether they have made any study of the tidal power stations at (1) Shashan in China, and (2) Rance in France, including a comparison of the life span and cost of decommissioning nuclear power stations; whether they are aware of any tidal barrage scheme being decommissioned; and how they assess the longevity of tidal power by comparison to other energy sources.

The Government has not undertaken any specific studies of the Shashan and Rance tidal power stations nor has it commissioned an assessment to compare the life span and costs of decommissioning for tidal and nuclear power stations.

Any proposed tidal range schemes would need to demonstrate strong evidence of value for money in the context of other low-carbon technologies inclusive of life span and costs of decommissioning, as well as details of their associated energy system benefits and environmental impact mitigation strategies before the Government could take a view on their potential or on the funding models appropriate for exploration.
