In the city of Helsingborg in Sweden, the municipal energy company Öresundskraft supplies District Cooling to a variety of customers in the downtown area. Customers include large users such as a pharmaceutical production facility and a major hospital together with an array of offices and other commercial buildings. The system that has been in operation since 1999 has now been reengineered to allow for an expansion to 30 MW (thermal) cooling capacity and to significantly improve energy efficiency and environmental performance.

The project in Helsingborg includes the construction of a new cooling production station housing industrial scale absorption chillers, sea water heat exchangers and large sea water pumps to mention a few pieces of main equipment. Another essential part of the project is the construction of a sea water intake and outlet pipe system with various filters and strainers. All designed to have a minimum impact on the underwater flora and fauna. The project has undergone an extensive environmental impact assessment and has obtained all necessary permits.
The project was initiated in 2015 to meet the increasing customer demand for District Cooling and to further improve the environmental benefits of the service. It was found that
the combination of using sea water and absorption cooling technology for the expansion rendered the highest energy efficiency and obviated the use of environmentally hazardous refrigerants such as HFC. The design was completed in 2016, construction commenced by mid-2017 and the facilities have been fully operational since the second half of 2018.
