SP Group runs Marina Bay's district cooling network, described by its operator as the world's largest underground system, supplying chilled water to Singapore's central district since 2006 with no supply interruptions. Two satellite plants due to operate in 2027 will add up to 15,000 refrigeration tons and take the network to a total capacity of up to 90,000 RT.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
Customers are reported to save more than 40% of the energy that in-building air-conditioning would use, and the network has run with zero supply interruptions since operations began in 2006. A later release frames the benefit differently: developments subscribing to the expanded network are expected to save up to 20 per cent of cooling-related energy consumption, with a reduction of 25,000 tonnes of carbon emissions a year for the central district once the satellite plants operate in 2027.
🎓 Lesson
The same operator publishes two savings figures for the same network — more than 40 per cent for customers against in-building air-conditioning, and up to 20 per cent of cooling-related energy for developments joining the expansion — and they answer different questions, so neither can be read as a revision of the other. Nothing here is an outside measurement: the third source is an association blog reproducing a newspaper summary of the operator's own commissioning announcement. And the phrase the network is known by, world's largest underground, is a size claim; the only performance claim it carries is the operator's own.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
