The PV systems are planned to be installed across 848 of the Board’s own blocks as well as 27 other government buildings.
Winning project developers will receive power purchase agreements (PPAs) at preferential rates, with the rooftop systems planned to come online by mid-2020.
The tender is the third issued by the Singapore’s SolarNova scheme, a joint effort between HDB and the Economic Development Board (EDB). It is also the largest, with previous tenders topping out at 40 MW.
Launched in 2014, SolarNova aims to promote and aggregate demand for solar PV across Singapore’s government agencies to achieve economies of scale, as well as drive the growth of its solar industry.
EDB works with SolarNova to aggregate demand from various government agencies, and provides funding for agencies to conduct feasibility studies and determine their solar PV requirements.
Agencies participating in the latest tender include the home affairs and education ministries, the National Environment Agency, the Building & Construction Authority and the National Heritage Board.
Meanwhile, Singaporean energy and water outfit Sembcorp Industries is set to develop rooftop solar projects totalling 4.1 MW to power two manufacturing facilities owned by airframe maintenance company ST Aerospace.
Both projects will be built, owned, operated and maintained by Sembcorp, with construction set to begin this month and completion scheduled for February and April 2018.
The $3.97m investment represents Sembcorp’s second rooftop solar energy deal for the aerospace and aviation industry in Singapore, the firm said.
