In October 2010, Sir Michael Pitt, the chief executive of the Infrastructure Planning Commission, requested an independent and authoritative evaluation of undergrounding. The Department of Energy and Climate Change sought the assistance of the Institution of Engineering and Technology as an independent assessor of that study by a company called KEMA. The study was to be funded by none other than National Grid. None the less, it went ahead, and the results were meant to be produced on 25 January. However, nothing happened. On 3 June, the IET issued a press release stating that KEMA had not been able to issue a report with which it was satisfied owing to a lack of data from National Grid, and so the IET could not endorse its work.
