Warsaw’s district-heating network is the focus of a second phase of digitalisation led by Veolia Energia Warszawa S.A. The project, known as ISC 2.0, builds on an earlier phase that equipped 2,500 heat substations with remote-control systems. 5
The new phase is planned to cover 5,814 heat substations and 14 main network chambers. Veolia’s technical specification describes installing automation, telemetry and remote-control equipment to monitor operating conditions, analyse network data and detect faults, while enabling remote adjustment of substations. The stated aim is to improve the reliability and quality of heat supply and make network operation more efficient. 13
The project received funding under Poland’s “Digitalisation of District Heating Networks” programme, financed from the Modernisation Fund and administered by the National Fund for Environmental Protection and Water Management (NFOŚiGW). The funding agreement with Veolia was signed on 14 November 2024 by NFOŚiGW president Dorota Zawadzka-Stępniak. The grant is PLN 30,515,755; the project’s total cost is reported at nearly PLN 65 million. 28
Veolia estimates that the planned measures could reduce heat losses by 64,691 GJ a year and cut carbon-dioxide emissions by 4,490 tonnes annually. These are projected benefits, not reported outcomes to date. Work is scheduled for completion by the end of 2027. 12
