Warsaw sold its heat network in 2011. The buyer wired up the substations and says failures fell, but nobody has shown how much the data did and how much the new pipes did.
what does this mean?
The strongest source is an independent non-academic evaluation: an audit office, a government or EU review, or an NGO. It grades who did the looking — not how well the project went. All four grades →Part of 1001 Smart Cities — 1,216 documented projects · 🏙️ 8 more in Warsaw · 🌡️ Heat & cooling guide · ⚡ Energy projects
Warsaw's district heating network, about 1,878 km of pipe serving some 19,000 buildings and 80% of the city's heat needs, belongs to a private company, Veolia Energia Warszawa. In 2011 the city sold 85% of its municipal heat utility SPEC to Dalkia, whose Warsaw company is now Veolia Energia Warszawa, for 1.44 billion złoty. The network buys its heat from seven sources, among them combined heat and power plants that ORLEN Termika operates in Warsaw; the national regulator URE approves each company's tariff. Between 2015 and 2017 Veolia put three pumping stations, 79 heating chambers and 2,500 substations under remote control from a single dispatch centre, whose display wall maps network parameters and potential failure points. A second phase, part-funded by a national grant, covers 5,814 substations and is due to finish by the end of 2027.
📊 Impact
The Supreme Audit Office (NIK) found that heat lost in the network fell from 13.9% of heat consumed in 2015 to 10.9% in 2020, one of the lowest shares among the municipalities it audited but above the 4% that government documents call desirable. Veolia reports 43% fewer failures in 2024 than in 2013 and credits the first remote-control phase with 14% lower heat losses and 40% fewer failures over nine years, without a method separating the digital layer from pipe replacement; almost 60% of the network is now factory-insulated pipe. A local news count gives 408 failures in 2013 and 319 in 2025, 24% of them unexpected. On 11 December 2019 a burst transmission main scalded two people and lowered pressure and temperature across Warsaw until other plants took over; after further failures in January 2021 a deputy climate minister set up a working group on the network's privatisation, while Veolia and the heat producer PGNiG Termika disputed whether a fault at the Żerań plant was to blame.
🎓 Lesson
Selling a network does not sell the duty to plan around it: NIK found that Warsaw adopted heat-supply planning assumptions in 2003 and replaced them only in August 2020, with a document that names no concrete tasks for anyone. Remote control shows a dispatcher which substation misbehaves, but in 2019 the cause of poor return-water cooling was still established by sending a fitter to the building. When an operator credits its digital programme with fewer failures, ask how that effect was separated from the pipes it replaced at the same time.

Paper by a Veolia Energia Warszawa engineer and two Warsaw University of Technology researchers using measurement data from Warsaw substations (PI System): about 3-4% of substations cool return water unsatisfactorily, and the cause is currently established only after a fitter visits the substation; it proposes on-line diagnostic algorithms.
