THE STRAITS TIMES BRANDED CONTENT ‘A good engineer likes to be challenged’: Mentor’s tough assignments sharpen skills of next generation Crucial technical knowledge to safeguard the nation’s power grid is passed down under a mentorship programme by SP Group SP Group's mentorship programme allows engineering veterans such as Mr Chua Khim Mong (top) to share their wealth of knowledge with the next generation of talent like Mr Chung Der Chyuan. PHOTO: SP GROUP PUBLISHED AUG 28, 2023, 4:00 AM SGT On any given day, Mr Chua Khim Mong would pose a hypothetical engineering problem in a group chat, challenging his team of technical officers and technicians to solve it. Mr Chua also leads weekly learning sessions and routinely assigns reading lists. No, Mr Chua is not a teacher – the 57-year-old is a senior principal engineer at SP Group. While his day job is to make sure Singapore’s national grid runs efficiently and seamlessly, he is also known as a no-nonsense mentor with close to 40 years of experience in the field. Mr Chung Der Chyuan, a principal engineer with SP Group and one of Mr Chua’s mentees, says that he has benefitted from the mentorship programme. “Mr Chua is very approachable and straightforward. He will explain his view and then let me figure out the details while keeping a watchful eye,” he shares. Today, both mentor and mentee collaborate to share their knowledge with colleagues, such as writing articles as part of a technical experts forum. Unseen heroes who pre-empt problems Mr Chua and his team are known as protection engineers and play an essential part in keeping Singapore’s lights on. Thanks to their work of monitoring and troubleshooting over 12,000 substations and 28,000 kilometres of electricity cables located across the island, Singapore’s ubiquitous power grid is world-leading in its reliability. While SP Group has monitoring equipment and technology that automatically adjust and reroute power across the grid to address anomalies, engineers remain crucial in fine-tuning systems and analysing faults. “With more than 50,000 protective relays, we look out for problems that can occur when there are firmware or hardware revisions in the relay equipment,” explains Mr Chua. Maintaining such a complex yet well-functioning national grid is no small feat, requiring depth and breadth in engineering knowledge and skills. To ensure such know-how, accumulated through decades of experience, is preserved and passed down to the younger engineers, SP Group has implemented the Technical Expert Scheme, which is an in-house mentorship programme designed to ensure the continuity of in-depth industry knowledge. A “living manual” with 40 years of experience Mr Chua first joined the Public Utilities Board, the precursor to SP Group, nearly four decades ago when he was 19 years old. Starting out as an assistant technician, he helped engineers who were more senior than him carry out relay testing and maintenance. Having risen through the ranks from a technician to a senior engineer, Mr Chua is well-placed to mentor his junior team members, guiding them through difficult situations they may face in the course of their work. “When I was a junior technician, our manager assigned a senior engineer to share with me and explain protection systems: the characteristics of a good protection system and how to set up relays. The presentation really changed my understanding of electrical engineering.” With nearly four decades of experience under his belt, Mr Chua believes tough assignments can help his mentees stretch their capabilities and grow in their careers. PHOTO: SP GROUP Now, Mr Chua places a similar emphasis on educating and motivating his junior colleagues. On his approach to skills upgrading, he says, “A good engineer likes to be challenged. I would give my engineers tough assignments to push them in sharpening their skills, and encourage them to keep working on solving the problem rather than walk away.” “Many of my officers have expressed interest in pursuing a degree course. This is something that I am very, very proud of because it shows a deep culture of wanting to upgrade themselves,” shares Mr Chua, who himself completed an engineering degree under a scholarship from his organisation in 1995. This is also testimony to his efforts of encouraging a team learning culture. To officers who want to attain additional qualifications, he reminds them, “Revise your maths because it is the hardest part of the course. After all, maths is a big part of an engineer’s job.” Mr Chua recounts one instance where he patiently allowed a junior team member to present his findings in a sharing session even though he had already spotted a miscalculation. “Rather than correcting him at the start, I want him to learn from his mistake and share the learning with his peers. “We remember and learn better through our mistakes,” Mr Chua explains. Often, his mentees would come to him for advice when they encounter complex situations on the job. “Most of the time, I already have the answer to their question. But I would send them off to come up with their proposed hypothesis and test method. This way, we can have two-way discussions and uncover new insights which can be applied in other situations,” he adds. He would also assign engineers technical papers to read so that they keep up with the latest trends and developments, before hearing their views on potential applications. Mr Chua pays close attention to the work of his juniors and always welcomes questions. “I tell them to never be afraid of asking seemingly silly questions. The most valuable lessons are learned from questioning and probing,” shares Mr Chua. In the spirit of learning from one another, Mr Chua has implemented surprise tests and weekly sharing sessions. “Once a week, we are all in the office to share interesting experiences or findings. Even the simplest finding or experience can be valuable to another. Everyone can benefit, including myself, regardless of rank or age.” “At the end of the day, the goal is to solve engineering problems more efficiently. But when possible, I will let my technical officers or engineers do things the hard way so that they get to learn more from the problem-solving process,” adds Mr Chua. As Singapore seeks to transition to a low-carbon future and tackle climate change, Singapore’s grid will be upgraded with new technologies to provide for developments like electric vehicle charging and more extensive deployment of solar panels. Technical experts like Mr Chua are key in helping the next generation of talent to keep abreast of change and new opportunities, and hone relevant skills and expertise.

Temporary roads pave way to safety A traffic marshal guiding pupils from Hong Wen School across a zebra crossing. Singapore Power has taken various safety measures, including deploying traffic marshals and building special access roads, in some areas where it is putting in deep underground tunnels to upgrade the island’s power infrastructure. ST PHOTOS: STEFFI KOH SingPower acts to prevent accidents during network upgrading project By JANICE TAI TWO temporary roads linked to expressways have been built to allow heavy vehicles to turn off directly into construction sites, bypassing schools and residential areas. The 200m-long special access roads, which cost $4 million, are among safety measures adopted by Singapore Power as it undertakes a $2 billion project to upgrade the island’s power network. The precautions, put in place especially for young children, come in the wake of a rise in fatalities from accidents involving heavy vehicles. There were 44 such deaths last year, up by about 40 per cent from 32 in 2012. Last year, a concrete mixer truck knocked down and killed two young brothers in Tampines, leading to much public outcry. In January, a motorcyclist was decapitated after his bike collided with a tipper truck in Tuas. Singapore Power began construction work on a 35km network of deep underground tunnels to house electricity cables last year. Eighteen worksites were set up across the island to build the tunnels. Two sites – in May Road and Kallang – were found to have high human traffic. “When we first started on the project, we were concerned when we saw schoolchildren sitting on the sides of the road and their parents parking,” Mr Michael Chin, Singapore Power’s managing director of special projects, told The Straits Times yesterday, referring to the May Road site. “So we decided to go beyond established industry practices for safety to minimise any risk,” he added. Singapore Power said it consulted the community and built an extra lane to the Central Expressway in the city-bound direction before May Road site CTE TOWNER ROAD Hong Wen School Source: Singapore Power May Road construction site MAY ROAD Only for heavy vehicles Previous vehicle access Whampoa Canal ST GRAPHICS the Balestier Road exit. This allows heavy vehicles to enter and exit the May Road construction site without taking the narrow roads around Hong Wen School and the residential neighbourhood around McNair Road, Towner Road and May Road. This road opened in May. Earlier in January, another road Kallang site Kolam Ayer CC Previous vehicle access GEYLANG BAHRU Kallang construction site GEYLANG BAHRU LANE PIE Access for all vehicles KALLANG SECTOR ST GRAPHICS was created off the slip road alongside the Pan-Island Expressway, in the direction of Bendemeer in Geylang Bahru. Construction vehicles now do not drive through Geylang Bahru and Geylang Bahru Lane, or around Kallang Basin Swimming Complex, to enter or exit the Kallang site. The Land Transport Authority said it does not track the number of temporary roads created for easier access to construction sites. The Straits Times understands that such a practice is not new, though most of the temporary roads built so far were aimed at easing congestion. For example, an access road to a controversial foreign worker dormitory in Serangoon Gardens was built in 2009 so that buses transporting the workers do not wind through the estate, which already has congestion problems. Besides building the two new access roads, Singapore Power also deploys traffic marshals at nearby schools and conducts road safety talks for the students. Heavy vehicle traffic during school peak hours is restricted and barricades are installed to prevent jaywalking around the construction sites. Retiree Lee Hee Ying, 64, said she makes it a point to walk her nine-year-old grandson to school every day. “It used to be scary to see all the big vehicles passing by, so it is more reassuring now with all the safety measures in place,” she said in Mandarin. Her grandson attends Hong Wen School. For site supervisor Dave Chew, 51, who has lived in the May Road area for about 30 years, the new roads also ease traffic congestion. “It’s not only about safety as the roads used to be packed with cars of parents and heavy vehicles, but now the flow is much smoother,” he said. jantai@sph.com.sg

4 Caltex stations to offer electric vehicle charging points Chevron Singapore, which operates the Caltex network of refuelling stations here, has teamed up with SP Group to set up electric vehicle (EV) charging points. The move, which comes 20 months after rival Shell set up its Recharge points, will see fast chargers at four Caltex service stations, in Chong Pang (North), Changi (East), Jurong Spring (West) and Dunearn (Central). They will be equipped with 50kW direct current (DC) chargers that can charge up an EV in as little as 30 minutes. The one at Changi will have two such chargers, which are designed to allow a compatible car to charge up to a speed of 100kW (provided only one car is utilising the point). The other three service stations will each be equipped with one 50kW DC charger. The charging fee is 46.63 cents/kWh, compared with 55 cents/kWh at Shell’s points. In a joint statement yesterday, SP and Caltex said they would study usage patterns and behaviour at the stations “to refine and enhance accessibility and utilisation, and plan for more charging points and locations”. The chargers will be installed by the second quarter of this year, and will be incorporated on the SP Utilities mobile app, which allows EV drivers to search for the nearest charging points, receive realtime updates on their charging sessions and make cashless payment. Shell Recharge is available at 18 Shell petrol stations across the island. It offers 50kW DC charging as well as 43kW AC charging. The chargers were set up by Shell-owned EV charging business Greenlots. Meanwhile, private EV charging firm EVOne is rolling out the fastest chargers in Singapore. EVOne chairman Elson Toh said it had brought in a 160kW DC charger capable of giving an EV 100km of range in as little time as it takes “for a toilet break”. “We are in negotiations with a party to install 100 points islandwide,” Mr Toh said. “As our cost is lower than current market players, we will be able to charge below 40 cents per kWh and still be profitable.” EVOne will also be bringing in a 180kW charger. Mr Toh said his company’s highspeed chargers are targeted at fleet owners such as logistics companies and taxi operators, which clock high mileages daily and require minimal downtime for their vehicles.
