Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, for what reason a 35-year contract for difference assumption was used for the Swansea Bay tidal lagoon value for money assessment when the project's estimated lifespan is 120 years.

The Department considered a range of factors in coming to this conclusion. These included the proposed design life of project, the extent to which bill payers should accept operating life risk, a rapidly evolving energy market, and the falling cost of other renewable technologies.
