Written reply to PQ on emerging urban wind technologies and their role in Singapore’s clean energy strategy

Question:

Mr Edward Chia Bing Hui: To ask the Deputy Prime Minister and Minister for Trade and Industry (a) whether the Government is evaluating emerging urban wind technologies such as compact rooftop turbines for low and variable wind conditions, given Singapore’s land constraints and limited wind resources; and (b) what role can such technologies play in Singapore’s distributed clean energy strategy. 

Written Answer by Deputy Prime Minister and Minister for Trade and Industry Gan Kim Yong

1.                  As the Member has pointed out, Singapore has limited land and low wind speeds. Conventional wind energy technologies are therefore unsuitable in Singapore. Newer technologies such as compact rooftop wind turbines may be able to overcome these constraints partially, but their long-term cost-effectiveness and impact on rooftop solar will need to be studied. Building owners who wish to install such devices on their rooftops may do so as long as they comply with the relevant regulations and technical requirements, including engaging a Licensed Electrical Worker to carry out any required electrical works.

2.                  The Government will continue to actively monitor the development of such turbines and other emerging energy technologies, as part of our efforts to build a diversified and resilient energy portfolio for Singapore.
