Question

Mr Edward Chia Bing Hui: To ask the Deputy Prime Minister and Minister for Trade and Industry (a) whether the Energy Market Authority is working with SP Group to expand and upgrade Singapore’s solar energy transmission and distribution infrastructure given that the Singapore Green Plan aims to achieve at least 2 gigawatt-peak (GWp) of solar energy deployment by 2030; and (b) if so, how.

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

1. The Energy Market Authority works with SP Group to review grid network plans annually, including augmentations that may be needed to support new sources of power generation. For solar deployments, these include upgrades to transmission and distribution infrastructure, as well as energy storage systems to mitigate the impact of solar intermittency. With solar deployment being on track to meeting the target of two gigawatt-peak (GWp) by 2030, SP Group has been following through with these plans, so that Singapore’s electricity transmission and distribution infrastructure keeps pace with the growth of domestic solar energy deployment.
