The Housing and Development Board (HDB) is taking advantage of demand for rooftop solar from multiple Singapore government agencies, aggregating this into a single leasing tender.
This will be the third tender launched under the SolarNova program, a joint effort between HDB and the Singapore Economic Development Board. The 50 MW being tendered in this round represents a 25% increase over the two previous 40 MW tenders.
The tender will close on January 31st 2018, projects should then be awarded in the second quarter. 848 HDB housing blocks have been identified for the installation of solar panels, as well as a further 27 government sites. Bidders will also be required to undertake actions to optimize the rooftops spaces for solar panel installation.
A total of eight government will participate, including four which have not previously been part of the SolarNova tenders. The participating agencies are: Building and Construction Authority, Institute of Technical Education, National Heritage Board, Sport Singapore, Ministry of Home Affairs, Ministry of Education and the National Environment Agency.
Projects awarded under this tender will be backed by long-term PPAs – meaning that private sector developers will build projects on the nominated rooftops, covering the upfront costs themselves, and then sell electricity generated to the government agency managing the building.
“Today, HDB is the largest stakeholder in PV installation, having committed to fulfil over 60% of the solar capacity that Singapore has planned to achieve by 2020,” says HDB’s CEO Cheong Koon Hean. “To allow government agencies to leverage HDB’s economies of scale, we have aggregated the demand across agencies under the SolarNova program, jointly with EDB. This has helped to spur solar adoption across the whole of government.”
HDB has a target to install 220 MW of PV on 5,500 of its housing blocks by 2020, and according to the agency, with this tender it has now committed to 190 MW of this. The SolarNova program represents the bulk of Singapore’s overall target to install 350 MW of solar by 2020.
