Who wanted it

Who asked for it
Regional cloud, banking and platform customers across Southeast Asia
Who approved it
Singapore froze new data center capacity from 2019 to 2022, then reopened with a competitive allocation requiring PUE ≤ 1.3 and disclosed water efficiency
What it serves
Southeast Asian cloud regions, financial networks and subsea cable landings
IT capacity
1,000 MW running of 1,400 MW announced

The first government anywhere to cap data center growth outright. Singapore imports most of its water and generates 94% of its power from gas, so every megawatt here is both carbon- and water-expensive — hence the cap.

Water and air figures are modelled from disclosed capacity, not measured — site-level error is roughly ±40%. Diesel backup generators are not counted, so on-site figures are floors. Full method.
