How this atlas is made · What “last verified” means

Since November 2021 Bucharest's municipal heating company Termoenergetica has run Termoalert, a public app and web map showing the live state of the city's district-heating network: every outage colour-coded by stage, with affected streets, repair progress and estimated restoration dates, plus push alerts for saved addresses. The transparency layer sits on top of a system in deep trouble. The network — 924 km of primary and 2,763 km of secondary pipes, much of it more than 25 years old — lost 37.73% of the heat fed into it in 2024, about 1.75 million MWh worth roughly 400 million lei, according to the city's own energy balance; in spring 2026 around 3,500 of the roughly 9,000 connected apartment blocks had hot-water problems at once. The map does not fix the pipes; it tells residents which day theirs will run cold.

📊 Impact

The map has become the de-facto public record of the network's state — press and residents track crises through it: in spring 2026 it showed about 3,500 of ~9,000 connected blocks with hot-water problems, while the city's 2024 energy balance (reported by HotNews) put real network losses at 37.73% (~1.75 million MWh, ~400 million lei).

🎓 Lesson

A transparency layer can outrun the asset it describes: publishing the failure in real time is cheaper and faster than replacing 40-year-old pipes — Bucharest got the honest map years before it will get the working network.
