Solar panels are set to be installed in Housing Board blocks managed by the Pasir Ris-Punggol and Holland-Bukit Timah town councils, in a move to reduce Singapore's carbon emissions and, in turn, the effects of climate change.
Work will begin in the first quarter of next year, said the HDB yesterday. It said the tender for the job had been won by local clean energy provider Sunseap.
This is the fourth such contract to be awarded and it involves 1,218 HDB blocks and 49 government sites that include 30 educational institutions and the National Library in Bugis.
It is also Sunseap's second contract under the Government's SolarNova programme, which compiles solar demand from various agencies to enjoy economies of scale.
The latest tender will reap a solar capacity of 70 megawatt-peak (MWp), 40 per cent more than the last awarded tender of 50MWp.
This could potentially offset about 42,152 tonnes of carbon emissions, an amount typically generated from powering about 17,500 four-room HDB flats every year.
Sunseap Group chief executive Frank Phuan said his firm will deploy at least 170,000 bifacial solar panels - the latest in solar technology - for the project.
Unlike typical solar panels, the bifacial solar panels can generate power on both sides and hence increase energy yield by up to 15 per cent. They are also more durable, lasting up to 30 years, compared with the usual 25 years, he said.
Mr Phuan said: "When this project is completed, Sunseap will have installed solar systems on top of more than 2,700 HDB blocks, or more than 27 per cent of all HDB blocks."
He added that the drive is in line with Singapore's pledge to switch to a cleaner fuel mix and cleaner energy solutions by 2030.
The HDB wants solar panels in 5,500 blocks by next year. As it is, the board already generates enough solar energy to power 57,500 four-room flats and reduce carbon emissions by 138,500 tonnes every year.
As of August, about 2,000 HDB blocks have been fitted with solar panels, and installation at another 2,370 blocks or so is in progress.
The solar power can be used for common services such as lifts, water pumps and lighting for common areas in the day.
HDB chief executive Cheong Koon Hean said the board is a key player in the development of green and sustainable towns and estates in Singapore, adding that it "will continue to ramp up efforts to harness solar energy and do its part to prepare for climate change".
The latest tender saw eight companies submit bids after the launch last December. The first tender was won by Sunseap in 2015, involving about 800 HDB blocks. The second went to Million Lighting in 2017 for 636 blocks and 31 government sites.
Installation works for the first three tenders should be completed by the end of next year.
