    In 1930 the first low temperature geothermal reservoir was harvested in Reykjavik. In the decades that followed more reservoirs where harvested and in 1990 Nejsavellir power plant began operation and supplied hot water to Reykjavík. Today all hot water used in Reykjavík has it's source from low temperature geothermal reservoirs or power plants that heat up cold ground water with geothermal heat. Around Reykjavík there are four low temperature reservoirs and two power plants that produce water for district heating.
    Optimization model has been made for one of the low temperature reservoir to optimise the production from, Laugarnes. Lumped parameter modeling was used to fit the parameters for the reservoir and mixed integer linear programming for the optimization.
    In this project the production optimization model is extended to take into count more than one low temperature reservoir. The model was tested and four experiments conducted. They showed good result though the model could only run over 28 weeks due to computational time. The computational time was extended from previous model because the optimization model was non linear instead of being linear and that proves to need much more processing power
