“Wait, didn’t they just close down the substation last month?”

Dear reader, you must have been thinking about The Substation.

We’re talking about a substation.

Well, technically, both places have something in common—one used to be the home of a power substation and the other will host an underground substation in the future.

See the difference?

The former, ultimately, was converted into an arts centre in Singapore.

If you’re more interested in the latter, read on to find out more!

SP Group Builds Large-Scale Underground Substation

The Singapore Power (SP) Group will be building Southeast Asia’s largest power station underground in Labrador, in order to optimise space for land development in our land-scarce island.

According to The Straits Times, the main contract has been awarded to Hyundai Engineering and Construction.

The substation is scheduled to be completed in 2024 and will serve the electricity needs of towns like Alexandra, Clementi, Keppel, Pasir Panjang, and the Science Park district.

The land above ground will be slated for developing a 34-storey commercial building also due to be complete in 2024.

Sustainable Infrastructure

The move will free up 3 hectares of prime land, said SP Group. That’s around the size of four football fields!

This project is in line with Singapore’s urban renewal plans and SPGroup’s own United Nations Sustainable Development Goals of ensuring access to reliable, sustainable and modern energy for all, as well as sustainable building infrastructure.

Substations are vital to powering our homes, offices, commercial buildings and public services. Basically, they transform high-voltage electricity to lower voltage so that it can be easily supplied to end-users.

The Labrador substation will be a 230-kilovolts facility that can power up to eight towns, each the size of Toa Payoh, when it is running at full capacity, said the company.


Requires Specialised Engineering Capacities

SP Group noted that building a substation underground is typically more resource-intensive than building one above ground due to the “complexities” in construction and the need to use materials that are suitable for subterranean environments.

CNA reports that specialised engineering capacities like detailed engineering studies and suitable construction methods are used to control the impact on surrounding buildings.

In addition, equipment in the substation must be of low fire risk, with cooling systems installed to prevent heat from building up.

SP Group believes that there are long term benefits to building an underground substation and that the benefits outweigh the risks.

As the station is located underground, they will also have a lower risk of being exposed and damaged, which enhances asset and network security.

This comes in addition to optimising our land for other developments.

Are you angry at someone now, and can’t get him or her out of your mind? Well, watch this video and you’ll know what to do next:

The company is confident that the substation will be a success.

Group Chief Executive Officer of SP Group Stanley Huang, said, “Leveraging our extensive experience in constructing the underground electricity cable tunnels that span across Singapore, we will be able to deal with the complexities of building this underground substation.”
