Terms for Infrastructure Upgrades and Range of Electrical Capacity in EV Charging Contracts in HDB Car Parks

Mr Chua Kheng Wee Louis asked the Acting Minister for Transport for the initial installations of electric vehicle (EV) chargers in close to 2,000 Housing and Development Board (HDB) carparks (a) whether the tenders for EV charger deployment includes electrical infrastructure upgrades; and (b) what is the range of electrical capacity that is available at HDB carparks today and the corresponding maximum number of chargers that can be installed before further capacity upgrades are required.

The electrical capacity available varies across carparks. Tenders for electrical infrastructure upgrades are separate from that for the deployment of electric vehicle (EV) chargers at the Housing and Development Board (HDB) carparks, as they involve different scopes of work and contractors. For example, in May 2025, a tender was awarded to upgrade electrical infrastructure at 300 HDB multi-storey carparks.

The electrical capacity available varies across carparks. HDB carparks can support three to 12 slow charging points today, based on typical electricity capacities.
