Two pilot projects to harness solar power
PUB has kick-started two pilot projects to harness solar power.
They are rooftop solar panels at Choa Chu Kang Waterworks, and floating solar systems on Tengeh Reservoir.
Both projects are part of a national effort to explore alternative and sustainable energy sources.
The panels at Choa Chu Kang Waterworks will harness solar energy for the plant's water treatment operations, and will generate an estimated 1.1 Gigawatt hours of electricity per year.
That's equivalent to the average annual energy consumption of about 250 HDB households.
Choa Chu Kang Waterworks will see up to 50 per cent of its peak daytime electricity supply for water treatment equipment, lighting and air-conditioning coming from solar power.
It's slated to be operational by the first quarter of 2015.
The floating solar systems at Tengeh Reservoir double up as an energy catchment to channel generated solar power into the national grid.
It'll generate up to 3.3 Gigawatt hours of electricity per year,
the equivalent of the average annual energy consumption of about 750 HDB households.
PUB will also conduct an environmental study to measure the systems' impact on reservoir evaporation, biodiversity and water quality.
A preliminary assessment has already identified potential benefits, like a reduction in reservoir evaporative rate, and a reduction in algal growth.
