To ask the Secretary of State for Energy and Climate Change what the maximum transmission system demand was in each of the last 20 years.

Mr. Kidney
DECC's data for the maximum transmission system demand are contained in our report ‘UK Energy Sector Indicators 2009: Supporting Indicators Dataset':

The following table shows the data for simultaneous maximum electricity load met (left axis) from 1985 to 2008.
