Mr Ang Hin Kee: To ask the Minister for Trade and Industry as Singapore gears up to be "Smart Nation" ready (a) what is the infrastructure support available to ensure that business transactions and daily digital operations are not affected when there is a power or technical breakdown such as the recent CBD power outage; and (b) whether there are plans to identify skills sets and put in place standard operating procedures to ensure workers are equipped with the skills and know-how to prevent similar incidents.

Written reply:

1. The Government recognises the importance of reliable and secure infrastructure, both in terms of power and telecommunication systems, as Singapore gears up for increasing digital operations as a "Smart Nation".
2. On the power system front, SP Power Grid (SPPG), the national grid operator, has a comprehensive infrastructure planning and maintenance regime to increase system reliability and minimise disruptions. This includes building in redundancy for critical components, continuous monitoring of the transmission network, and conducting preventive maintenance. Workers are trained and reminded to adhere strictly to operating procedures. That said, there can still be the occasional instance of human error, such as during the blackout on 1 June 2018. We have adopted a calibrated risk-based approach in systems planning, with a framework in place to enable quick restoration of power when needed. This calibrated risk-based approach has served us well, with our power system being among the most reliable in the world. For instance, from FY13 to FY17, Singapore' average annual disruption per consumer ranged from 12 seconds to 45 seconds, compared to latest FY15 figures of 4 minutes for Tokyo and 23.4 minutes for Hong Kong.
3. For telecommunication infrastructure, MCI and IMDA have also put in place measures to ensure resilience. These include Codes of Practices that set baseline requirements to ensure that our telecommunication networks are fit for purpose and on par with international best practices, as well as to encourage telecommunication operators to adopt more advanced resilience practices. IMDA also engages the telecommunication operators regularly to conduct exercises on recovering from service disruptions, and discuss initiatives to enhance the resilience of our networks.
4. Telecommunication service disruptions sometimes occur due to cable cuts committed by errant contractors. MCI and IMDA have therefore put in place several measures to mitigate the risk of such disruptions. For example, the Telecommunications Act requires contractors to employ licensed Telecommunication Cable Detection Workers to detect the presence of underground cables prior to commencing earthworks. In addition, IMDA holds regular dialogue sessions with contractors to encourage the adoption of precautionary measures when carrying out earthworks, as well as the need for training for workers. Where disruption to telecommunication services occurs due to cable cuts, IMDA will not hesitate to enforce any breaches of the Telecommunications Act by prosecuting the relevant parties in Court. MTI and EMA also have similar measures in place for earthwork damage to electricity cables, and these are enforced through the Electricity Act, relevant Code of Practices and licensing conditions.
5. To minimise the impact on consumers in the event of disruptions, IMDA incentivises telecommunication licensees to restore services quickly by imposing penalties that will take into account the duration of the disruption, amongst other factors. IMDA also prescribes baseline requirements for key telecommunication licensees' business continuity planning to facilitate recovery during service disruptions.
