SINGAPORE: Singapore Power is undertaking a one- to two-year study on the impact of electric vehicles on the
national grid.
It is using three electric vans to simulate larger-scale adoption of eco-friendly transport.
Based on the findings, authorities will take steps to ensure the power supply can cope with thousands of such
vehicles charging simultaneously.
How much power is needed to charge 25,000 electric cars?
There are currently some 630,000 cars on Singapore's roads today.
Wong Kim Yin, Group Chief Executive of Singapore Power, said: "If they are all charged at the same time, the
amount of power required would be the same as that required to power the whole of Ang Mo Kio. And these
vehicles could be charged from anywhere on the island other than its home base.
"So as a result, the energy flows through the electricity grid will become more dynamic. Such dynamic flows of
electricity could affect the operation of the grid, and if not managed properly, will impact reliability."
With computer simulations, authorities are studying how vehicle-charging affects power supply and its reliability.
Singapore Power will use five charging stations to test the impact of electric vehicles. They are sited in places
like Jurong, Kallang and Telok Blangah.
Hopefully, these vehicles will be as friendly to the national grid as they are to the wallet.
Arnaud Mourgue, Area Operations Manager of renault, said: "To run an electric vehicle, costs four cents per
kilometre to run. Petrol or diesel engine cost 20 cents per kilometre to run. On top of this, you've got a discount
for servicing, which is 50 per cent compared to a petrol or diesel vehicle due to less fluid and less parts to
change."
It costs $6 dollars to charge an electric car, which can then run for 185 kilometres.
Renault is selling electric vehicles in Singapore at between the S$120,000 to S$170,000 price range - with Green
Vehicle Rebates.
And besides these, there are more exotic options, including a half-a-million-dollar electric supercar.
