Electricity is essential in dense urban environments, especially in cities such as Hong Kong, where residential high-rise buildings become uninhabitable without it. A major power outage at a Tsuen Wan housing estate this week should be a warning about the stability of energy systems in ageing blocks amid increasingly extreme weather.

At least 3,000 residents at Phase 1 of Tsuen Wan Centre were left without water and lift services for over 24 hours before electricity was restored around noon on Tuesday. There were concerns about the health and safety of those living in some 1,000 apartments across five blocks and a care home for people with disabilities.

Lawmaker Jody Kwok Fu-yung said the lack of electricity in the sweltering heat had a “severe impact” and many elderly people, including those living alone, found it “very difficult” to get around.

Volunteers deserve praise for quickly stepping in to help people manage stairs and delivering supplies such as meals and water. The Water Supplies Department installed drinking water tanks and dispatched water trucks near the affected buildings. The Home Affairs Department opened four community halls to accommodate residents in need, while Tsuen King Circuit Sports Centre was also made available as a temporary shelter.

Power supply is largely reliable in Hong Kong, though there have been several high-profile electricity supply issues in recent years. One was a major blackout in 2022 that affected more than 160,000 households in northwestern Hong Kong after a bridge carrying high-voltage CLP cables caught fire. As recently as February and April this year, voltage dips trapped dozens of residents in lifts.

Such incidents have sparked calls for inquiries to ensure there are no systemic problems that need to be addressed in a city that cherishes its reputation for reliable power supply, under a scheme of control which assures suppliers of a return on capital invested.
