The Water and Electricity Department (WED) of the Emirate of Abu Dhabi is studying the possibilities of increasing the generation capacities of their existing equipment. This paper will discuss one way of increasing the power output from one operating station — the Umm Al Nar East (UNE) station. The results based on data recorded for one year show that an extra 65 MW could be obtained continuously from the station. This requires the supply of 3 sets of back pressure turbines (BPT), which will use the medium pressure steam available at the station, instead of passing it through pressure reducing valves. The exhaust steam will be sent to the desalination plants. The price of these extra power generators will be cheap compared to separate power generators having the same capacity, as the boilers and condensers are already on the site. Also, the running cost for this extra generation will be less as most of the steam is produced by heat recovery boilers at almost no fuel cost. The final results after installing the BPT's show that the cogeneration efficiency of the station will improve. This improvement will reduce the unit price cost for both water and electricity.
