    Ruddock, Joan
    The latest figures on transmission losses are available in the report published by National Grid in June 2008 “Investigation into transmission losses in the UK electricity transmission system”. The report is available from the national grid. The proportion of electricity generated lost in transmission is estimated at 2 per cent. of the total energy transferred across the network, the out-turn of transmission losses is estimated at 6.9 TWh for 20082009.There are no specific figures available for the proportion of the electricity generated from offshore wind farms lost in transmission to final users. Such losses will vary depending on a range of factors such as location and size of wind farms as well as the distance of the wind farm to the onshore grid.
