SINGAPORE: Preliminary investigations following this week's power outages across multiple estates in Singapore suggest that the country's backup procedures are in place and working fine, said Trade and Industry Minister Chan Chun Sing on Friday (Sep 21).
This is illustrated by how it took just 15 minutes for the system to be restarted when two power-generating units – one at Sembcorp Cogen and the other owned by Senoko Energy – tripped early on Tuesday, causing multiple parts of Singapore to be hit by blackouts.

“We are also looking at the opportunity to review our backup procedures to make sure that the procedures are working fine,” said Mr Chan. “Our preliminary investigations show that our backup procedures are in place."

On that, Mr Chan elaborated: "When the first system failed, our backup system kicked in immediately and even when that failed, we had sufficient capacity to restart after 15 minutes. That was what happened and hence within 38 minutes, we were able to fully restore power to the system."
For buildings that suffered intermittent power failure after that, it was due to how these buildings needed to reset their individual internal systems, he added.
"I'll like to assure Singaporeans that we have sufficient capacity in our system and this is what we have demonstrated that night," said Mr Chan, while adding that it is "too premature" to talk about penalties for the companies involved.
Mr Chan was speaking to the media following the announcement of a nationwide roll-out for the Open Electricity Market – an initiative by the Energy Market Authority to open the local power market fully to competition.
