Excess heat from kraft pulp mills can be used either for internal purposes in the mill or externally, as district heating. Previous studies have shown that the trade-off between internal and external use of excess heat from kraft pulp mills depends mainly on energy prices and the demand for heat. The aim of this study is to investigate whether the trade-off between the investment options is altered when the option to produce district cooling through absorption cooling is introduced. The influence of absorption cooling on the trade-off between internal or external use of excess heat is investigated through modeling the pulp mill and the Energy Company (ECO) using the energy systems modeling tool reMIND. To obtain a broader system perspective, the kraft pulp mill and ECO are modeled within the same system boundaries. The results of the optimizations show that absorption cooling mainly benefits investments in bio-fuelled CHP and only influence the trade-off between internal or external use of excess heat when the conditions for CHP are unfavorable, for instance when the price of bio-fuels is high and the price of electricity certificates is low. The larger heat demand made increased electricity production possible which not only increases the system revenue but also decreases the CO2 emissions of the system.
