Abstract

On January 1st 1998 three UK power companies began to investigate a novel system designed to reduce the possibility of coal-fired power stations causing the new 100 ppb 15 minute ambient air quality SO] standard being exceeded. Three 2000 MW power stations were selected to take part in a one year trial. Although the trial did not involve any actual changes to operation of any power station, it was designed to reflect in real time what would happen were such a system to be operated in reality. The protocol centred around the use of meteorological forecast data and dispersion modelling to predict exceedances of the air quality standard and hence enable changes to power station operation to take place. A large amount of data has now
