SP Group is constructing South-east Asia’s first large-scale underground substation in a bid to optimize space and freeing up about three hectares of prime land space. Given the site’s proximity to Keppel golf club, which is zoned for residential use, as well as to Mapletree Business City, there is potential for future property development which can support real-estate uses such as commercial use.
The land freed up will make way for a 34-storey development; the 230 kV substations will serve the electricity needs of nearby towns; the substation will be integrated with the 34-storey commercial building, as one part of the larger Greater Southern Waterfront.
SP Group’s chief executive officer Stanley Huang announced: “In our business of enabling a low-carbon, smart-energy future, we are building sustainable and resilient infrastructure. This is in line with Singapore’s urban renewal plans and our own SDG (United Nations’ Sustainable Development Goal) of ensuring access to reliable, sustainable and modern energy for all, and tapping innovation to build sustainable infrastructure.”
The building contract has been awarded to Hyundai Engineering & Construction Co.
Noting that building an underground substation requires more resources and specialised engineering capabilities, the electricity and gas distribution company highlighted that in the long term, underground substations have a lower risk of being exposed and damaged. This would ensure asset and network security, SP Group added.
SP Group said that the substation and the commercial building are scheduled for completion in 2024.
