Resalta, in partnership with Energetika Ljubljana, is implementing a pilot project for smart district heating systems in the city of Ljubljana. The main goal of the project is the inclusion of 4,500 district heating substations into one unified IT system, effectively bringing the entire district heating network under central supervision.
As one of the largest energy distribution companies in Slovenia, Energetika Ljubljana manages two of Slovenia’s largest infrastructure systems for remote energy supply: the Ljubljana district heating system and the Ljubljana gas distribution system. Its district heating system is one of the most environmentally friendly energy supply systems in existence but is still subject to heat losses and other challenges inherent to the distribution of hot water for heating. Energetika Ljubljana chose to partner with Resalta in order to participate in this innovative project, with a focus on providing reliable heat to customers, while continuously optimizing the distribution of heat in order to maximize environmental and economic efficiency.
In order to achieve this, the project has implemented a comprehensive IT platform for monitoring, managing and optimizing the district heating substations. Receiving data directly from the substations makes it possible to identify issues even before they arise and create conditions for solving them, thus reducing losses and down time. Besides generating fuel savings due to lower thermal losses, with the use of accurate and timely heat consumption data Energetika Ljubljana will be able to optimize distribution, thus also saving on electricity due to lower water flow in the network. Moreover, the innovative web interface allows for active involvement of customers, enabling them to monitor their own consumption and adjust it accordingly.
The investment is co-financed by the European Union from the European Regional Development Fund and the Republic of Slovenia.
