SP Group commits $35m to upgrade skills of staff Joanna Seow Manpower Correspondent After attending a one-day course earlier this year, gas regulator technician Cham Tai Kieo found he and his colleagues could halve the travelling time needed to check and maintain some 400 gas overground boxes across the island. The 37-year-old learnt how to assemble and read smart sensors, which energy utilities provider SP Group has started using to remotely monitor pressure in gas regulators. With new technology shaking up the energy industry, Mr Cham’s employer SP Group and the Union of Power and Gas Employees (Upage) have been collaborating since January last year to identify skills gaps and find suitable courses for workers, so that they can take on new or transformed jobs. So far, about 2,800 SP Group staff have benefited. The company said yesterday that it will now spend $35 million over the next three years to upgrade the skills of all its 3,600 staff, working with the union to prepare workers as the energy sector faces digitalisation and rising customer expectations. This will be done via a company training committee set up by SP Group and the union, with the two organisations formalising their collaboration by signing an agreement. National Trades Union Congress (NTUC) secretary-general Ng Chee Meng witnessed the signing yesterday at SP Group’s headquarters near Kallang. SP Group’s committee is the third to be set up by Upage and energy companies in recent weeks, following similar agreements with YTL PowerSeraya and City Gas. In a joint statement, SP Group and the union said workers will be able to further develop competencies in the areas of customer service, cyber security, data analytics, safety and skills for a digital workplace. Upage general secretary Abdul Samad Abdul Wahab, who is a principal technical officer at SP Group, encouraged workers to go for training. He said a number of those who had attended training sessions have seen their salaries rise by 8 per cent to 20 per cent “Let’s not be afraid to adapt, embrace and adopt the various technologies and use them in our daily jobs, just like we are in our daily lives,” he said, speaking to about 200 company and union representatives at the signing event. NTUC started setting up company training committees this year and aims to have 1,000 of them over three years. So far, over 60 have been set up across industries such as manufacturing, lifestyle and the public sector. Group chief executive of SP Group Wong Kim Yin said that as new technology shakes up the energy industry, “we want to help our people adapt and prepare ahead of this potentially disruptive transformation”. Mr Cham said he used to have to install a chart recorder device and return the next day to pick it up for analysis. But with smart sensors, gas pressure can be monitored from the depot. Mr Cham, who has been with SP Mr Cham Tai Kieo, a gas regulator technician with SP Group, says his training has helped him increase productivity. ST PHOTO: KELLY HUI Group for about six years, said he next hopes to learn how to read pressure charts that are generated by the sensors. It helps the team to pick up any abnormalities and try to fix them before customers’ gas supply is affected. “Using the sensors increases our productivity and helps us maintain reliability for customers, which can enhance my career,” he said. joseow@sph.com.sg

THE STRAITS TIMES BRANDED CONTENT Making air-conditioning greener: How he's helping Singaporeans reduce their carbon footprint The centralised cooling system that he and his team at SP Group are building for Tengah new town will be 30 per cent more energy efficient, which contributes to the nation's climate goals Mr Liu Yue inside one of the thermal storage tanks in the world's largest underground district cooling network operated by SP Group PHOTO: SP GROUP PUBLISHED NOV 30, 2022, 4:00 AM SGT Mr Liu Yue has a new engineering challenge. The 38-year-old Principal Engineer is part of the team designing and building the first centralised cooling system (CCS) for a residential estate in Singapore – in the Tengah eco-town. Instead of individual compressor units mounted on aircon ledges, Mr Liu is tasked to build a centralised system which circulates chilled water to and from each flat to cool air within the flat, thus delivering air-conditioning service to 19,000 households in the estate. The first homes will be ready in 2023. “It is definitely a challenge because we have to work with many other parties to overcome the space constraints,” says Mr Liu. In his previous posting in SP Group, Mr Liu worked at an underground district cooling system that serves the Marina Bay central business district. But this time, Mr Liu has to deal with space constraints of a different kind. “In HDB flats, it’s not cost-efficient to have large underground spaces, so we have to think out of the box and find space for our cooling equipment,” Mr Liu shares. Eventually, the project team decided to place the CCS equipment on the HDB block roof, which would allow precious ground space to be used by the community. HDB flat rooftops would host the CCS equipment which service a cluster of HDB blocks. This arrangement would optimise the cooling output of the CCS equipment, achieving both energy efficiency and supply reliability. Mr Liu is proud that he plays a part in transforming the energy sector to meet climate goals.

We are helping to improve lives by the meaningful transformation of the power industry. This brings me a lot of satisfaction as an engineer,” he says. Reaping benefits from economies of scale In a CCS, a few interconnected centralised plants produce chilled water which is piped to individual households. “Colder” chilled water produced at the centralised plants is circulated to the indoor air-conditioner (known as chilled water fan coil unit or FCU) in each flat. The FCU recirculates the air within the flat and cools the air. In the process, the chilled water is “warmed” up. The warmer water is then returned to the centralised plants to be chilled again and repeat the process. Because the centralised chilled water plants are 30 per cent more energy efficient by design than individual split units found typically in households, CCS is more economical for air-conditioning of flats. Mr Liu Yue is the deputy lead for the construction of the centralised cooling system that will deliver air-conditioning service to 19,000 households in Tengah eco-town. PHOTO: SP GROUP Air-conditioned comfort with lower emissions Air-conditioning is ubiquitous in tropical Singapore. According to the Department of Statistics, about 80 per cent of Singapore households own air-conditioners, and from NEA household electricity consumption profile, air-conditioning contributes about 24 per cent of the average household electricity consumption. With rising incomes and warming temperatures, air-conditioning ownership and the use of air conditioners are set to rise. Worldwide, the use of air-conditioners results in the emission of nearly two million tonnes of carbon dioxide every year, or about 4 per cent of the global share. There is therefore an increasing need to reduce carbon footprint from more energy efficient air-conditioning systems. The reduction in electricity consumption from CCS will contribute towards Singapore’s ambitious carbon footprint reduction commitments. Singapore aims to accelerate its timeline to reduce greenhouse gas emissions, peaking emissions in 2030 and achieving net-zero emissions by 2050. While Singapore’s carbon emissions represent a small percentage of the global share (0.13 per cent in 2020), Singapore’s per capita emissions are very high, about twice the global average at 12 tonnes annually. If Singaporeans can reduce their carbon emissions significantly, it would demonstrate how people can meaningfully counteract climate change without severely lowering their standard of living. Mr Liu is energised by his contribution to help Singapore meet its climate goals. “The CCS we are building will enable Tengah residents to lower their carbon footprint through an energy-efficient cooling system. Just by living in the estate, each resident has already started the sustainability journey. This is a huge motivating factor to every engineer working on the Tengah project. “We started from ground zero and had our fair share of roadblocks in the journey. With all the hard work we put in, it is very rewarding to see everything come to fruition. I am glad to be able to play a part in pioneering the most futuristic town in Singapore towards smart and sustainable living. I guess it's my way of leaving my mark – a green one,” adds Mr Liu. Energy-efficient cooling for a warming world Leading the effort for more efficient cooling systems, SP Group will be implementing various types of cooling systems in different capacities, both in commercial and residential buildings. Its flagship district cooling system in the Marina Bay CBD network will be expanding to cool 28 commercial buildings by 2026. The savings in electricity consumption is estimated to reduce about 20,000 tonnes of carbon emissions annually, equivalent to removing 17,672 cars off the road. SP Group is establishing Singapore’s largest industrial district cooling system for STMicroelectronics at the Ang Mo Kio Technopark. By the time it is operational in 2025, it will reduce carbon emissions by up to 120,000 tonnes annually. SP Group is also constructing a distributed district cooling network in Tampines, where seven existing buildings will be retrofitted by 2025. Transitioning the world into a decarbonised future Beyond its role as the national grid operator, SP Group actively pursues sustainability initiatives as a key part of Singapore’s climate strategy. Its climate initiatives include a nationwide electric vehicle (EV) charging network, deploying rooftop solar energy generation, and smart electricity metering to monitor and reduce usage. SP Group has also exported these technologies to overseas markets where there is demand for sustainable energy solutions. SP Group has provided expertise to build district cooling and heating systems, smart metering and solar power generation in cities in China, Thailand and Vietnam.
