Written Reply to Parliamentary Question on Monthly Average Electricity and Water Consumption Rates for Households

Question:

To ask the Minister for Sustainability and the Environment (a) in 2024, what was the monthly average electricity and water consumption rates for households living in (i) HDB flats broken down by flat type (ii) private condominiums and (iii) landed properties; and (b) what is the projected trend of these rates in the next five years.

Answer:

1 The average monthly consumption for electricity and water[1] in 2024 are as follows:

a)    For households living in HDB flats,

      · 1-Room and 2-Room HDB flats: Electricity: 175.7 kWh, Water: 8.9 m³

      · 3-Room HDB flats: Electricity: 276.1 kWh, Water: 12.2 m³

      · 4-Room HDB flats: Electricity: 380.7 kWh, Water: 15.4 m³

     · 5-Room and executive HDB flats: Electricity: 464.0 kWh, Water: 17.1 m³

b)    For private apartments and condominiums: Electricity: 522.0 kWh, Water: 13.4 m³

c)    For landed properties: Electricity: 1208.2 kWh, Water: 30.6 m³

2 We expect the existing household consumption trends for electricity and water to continue in the next five years. For electricity, household consumption would likely continue to see a gradual increase, due to factors such as switching from town gas and liquified petroleum gas to induction cooking, increased air-conditioner usage with higher temperatures and greater electric vehicle adoption. For water, household consumption has been gradually decreasing with adoption of more efficient water fittings and appliances in homes.
