Rehabilitation of the district heating network in Pristina, Kosovo
The rehabilitation of Pristina’s district heating network aimed to enhance energy efficiency, reduce heat and water losses, and improve indoor climate control for thousands of residents. The project included the installation of approximately 17,000 meters of new pre-insulated underground pipelines, significantly minimizing energy waste. New pipelines extended the network to Kalabria, Mati, Center, Dardania, Ulpiana, and Sunny Hill, connecting around 1,500 residential apartments, along with two kindergartens and three schools, ensuring a reliable and sustainable heating supply.
Client:
Termokos AD – Pristina
Location:
Pristina, Kosovo
Project year:
2018–2021
Funding
European Union
Project Scope
✅ Pipeline Installation & Replacement: ~8 km
✅ District Heating Substations (new & replaced): 171 units
✅ Capacity Range: 50 kW – 1200 kW
✅ Total Installed Capacity: 94 MW
Key Outcomes & Benefits
✅ Reduced Heat & Water Losses:
- Network heat losses dropped from 18.7% (2016) to 11.9% (2021).
- Water replenishments decreased from 22 times per year (2016) to just 5 times (2021).
✅ Improved Energy Efficiency:
- The newly installed district heating substations provide precise temperature control, optimizing energy use and comfort.
- Heat meters ensure accurate monitoring and fair billing for consumers.
- Real-time data transmission to Termokos’s control room enables rapid response and system adjustments.
✅ Enhanced Air Quality & Sustainability:
- The switch from oil and electricity-based heating to district heating significantly reduces air pollution in Pristina.
- High-performance thermal insulation on all pipes minimizes heat loss into the atmosphere.
✅ Optimized System Performance:
- The temperature difference between return water on the primary and secondary sides remains stable, not exceeding 5°C at any of the 171 substations.
