asked the Secretary of State for Energy if he will estimate the United Kingdom's demand for electricity in 2005, 2025 and 2050, respectively, and the proportion of that demand that would be provided by the proposed Severn barrage.

The production of forward estimates of electricity demand is the responsibility of the electricity supply industry.

To the extent that electricity demand grew in the future, this percentage would become smaller.
