SP Group is constructing the first large-scale underground substation in Southeast Asia. Located at Labrador, SP will build its 230kV electrical substation underground to optimise space in land-scarce Singapore for urban growth and development. The substation alone will free up three hectares of prime land space, or the equivalent of four football fields. When in service, the substation will serve the electricity needs of nearby towns such as Alexandra, Clementi, Keppel, Pasir Panjang, and the Science Park district.
Group Chief Executive Officer of SP Group, Stanley Huang, said: “In our business of enabling a low carbon, smart energy future, we are building sustainable and resilient infrastructure. Taking a holistic approach, we are constructing this substation underground, freeing up space above for a 34-storey development. This is in line with Singapore’s urban renewal plans and our own United Nation’s Sustainable Development Goals of ensuring access to reliable, sustainable and modern energy for all and tapping on innovation to build sustainable infrastructure.”
In addition to optimising land resources for other purposes, underground substations have a lower risk of being exposed and damaged. This will enhance asset and network security.
The Labrador underground substation is part of the Urban Redevelopment Authority’s underground Master Plan 2019. The underground electricity substation at Labrador and an above-ground commercial building are scheduled for completion in 2024.
