§ Mr. HainTo ask the President of the Board of Trade how many losses of power at the Rheola relay station have occurred in each year since 1990; and what is the average across Britain.
185W
§ Mr. BrookeI have been asked to reply.
The information is not available in the form requested. The Independent Television Commission has determined national standards of reliability, measured in terms of service availability to viewer. For relay stations such as Rheola the minimum standard is 99 per cent. In 1993, there were seven periods in which electrical power was lost at the Rheola transmitter, of which five were for maintenances, resulting in transmissions being available to viewers for 99.5 per cent. of the time.
