SP Group partners BCG Energy on solar project in Vietnam � MON, AUG 02, 2021 - 1:20 PM YONG JUN YUAN �junyuany@sph.com.sg �@JunYuanBT SP Group (SP) and BCG Energy, a wholly-owned subsidiary of Bamboo Capital JSC, have formalised a joint venture (JV) to invest in rooftop solar and other renewable energy projects in Vietnam. In a press statement on Monday, SP said that it will own 49 per cent of the JV, while the wholly-owned subsidiary of Bamboo Capital JSC will own 51 per cent. The JV will have an initial target of 500 megawatts (MW) of rooftop projects by 2025, contributing to Vietnam's target of having 30 per cent of its electricity generated through renewable energy sources by 2030. As part of the JV's rst rooftop solar project, it will work with Vinamilk, Vietnam's largest dairy production company, to install a combined 25MW of rooftop solar power across nine factories and seven farms. The installation will generate 35,000 megawatt-hour of clean electricity annually, enough to power approximately 20,000 households in Vietnam. It also amounts to a reduction of 32,000 tonnes of annual carbon emissions, equivalent to taking approximately 7,000 cars o the road. The JV will also acquire 28MW of operational rooftop solar assets across eight commercial and industrial sites located in South and Central Vietnam. BCG Energy chief executive o cer Tuan Pham noted that Vietnam completed and connected more than 100,000 rooftop systems to its grid and that there is strong growth potential in this market segment in Vietnam as it develops. "We believe this will promote the use of clean energy in manufacturing companies and contribute to the sustainable growth of the economy," he said. SP chief executive o SP as it steps into the Vietnamese market. cer Stanley Huang noted that the partnership is a key milestone for "Our combined expertise and ambition in renewable and sustainable energy solutions will o er customers more options and encourage their transition to clean energy sources," he said.

Media Release SP Group Holds Its First Volunteers Festival, Launching Toolkit to Enlarge Its Volunteering Footprint Singapore, 4 October 2023 – Empowering employees to volunteer regularly and creating pathways for them to do so easily. SP Group (SP) has reaffirmed this commitment at its inaugural Volunteers Festival, held at the kick-off of its largest annual staff volunteer initiative. SP aims to encourage all its business units to participate in volunteer activities that the company organises throughout the year. SP has also launched Heart at Work: A Guide to Corporate Volunteering, to provide tips on ways for anyone to volunteer, matching interest and talents with various needs in the community. Drawing from the company’s decade-long experience in sustained and coordinated volunteerism, the guide aims to inspire more of its 3,700 employees to embark on their journey of creating meaningful impact and influence their colleagues, family and friends. The guide also serves as a toolkit for organisations looking to build their corporate volunteering culture. The festival at SP’s head office culminated in the flag-off of SP Power Packs – the company’s largest annual volunteer initiative. Staff volunteers, known as SP Heart Workers, deliver care packs of essential items to 10,000 lower-income households throughout the year. The initiative was scaled up five folds in 2022 to its current scope. SP has also extended the reach of the packs, from seniors to social service users across to age spectrum, such as children and youth. The items in the packs are customised according to the different age segments. Speaking at the festival, SP Group’s Chairman, Ms Leong Wai Leng, said, “SP Group is committed to ensuring that our contributions to the community are made in a sustained manner, and have a lasting impact. We have created pathways for staff to be involved by sharing their time and talent. No effort is too small. It could go a long way to brightening someone’s day, extending companionship or being a mentor or role model to the next generation.” By volunteering together, staff enjoy team bonding while alleviating the operational load of social service agencies. Besides Power Packs, activities include exercise sessions and outings for seniors, packing and distributing learning resources and conducting reading programmes for children, as well as sports activities and learning journeys for youth. These efforts complement SP’s philanthropic contributions to programmes for seniors, children and youth. Ms Leong, joined by SP’s Board members, Executive Leadership Team and union leaders, flagged off the Power Packs convoy. Leading the line-up were SP Heart Workers driving SP’s electric vehicles and others in their own vehicles. Electric vehicles now make up close to 40 per cent of SP’s vehicle fleet. The Festival featured SP Heart Workers sharing their experiences. SP’s partners AMKFSC, KidSTART Singapore, TOUCH Community Services, and Youth Guidance Outreach Services were also present with stories of how volunteers play a pivotal role in uplifting beneficiaries and improving their quality of life.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Protecting Our Underground Network RELIABILITY Principal Engineer James Ou and his team conduct checks on worksites to ensure electricity cables and gas pipes are not compromised. When a patrol officer from SP Group’s Earthworks Surveillance & Patrolling (ESP) section pulled up at a Whampoa West construction worksite in November last year, what he did not expect to find was an excavated trench right over one of SP’s 230kV transmission cables – and a water pipe laid above it. The checks by ESP had uncovered the non-compliance of a contractor who was not following the approved plans they submitted to SP previously. Beyond the works themselves, leaks, condensation or breaks in the water pipe could pose a threat to the high voltage electricity cable below, and cause a power outage. SP’s critical electricity cables and gas pipes – networks spanning 11,500km and over 28,000km respectively – are buried underground. At the same time, across Singapore, there are always ongoing works for various construction projects. “That is why we carefully manage and monitor all excavation works – it minimises the risk of an electricity disruption or a gas leak,” explained Principal Engineer, James Ou, who heads ESP and oversees a team of almost 60. Detect and protect: Technical officer Mohamed Saiful Matsaid (left) uses a cable locator to detect electricity cables hidden underground as Principal Engineer James Ou (right) marks out the path of the cable. Mr Ou, who is 36 and studied electrical engineering, joined SP in 2008. He worked in electricity operations and maintenance before assuming his current role in November 2017. Now, he prevents problems instead of fixing them. In the case mentioned, the contractor of another organisation had conducted unauthorised work. Timely intervention averted damage, but the site’s Registered Excavator Operator was still suspended from excavation work for three months. The Energy Market Authority also took action against the contractor. Damage control: When contractors do not comply with requirements, Earthworks Surveillance and Patrol officers will issue a “stop-work” order. The incident highlights the critical role SP’s compliance officers play in keeping Singapore’s electricity and gas supply humming – especially against its booming construction landscape. Despite the acronym, the ESP team doesn’t rely on a sixth sense to warn them of danger. Instead they enforce stringent requirements, as well as rigorous and frequent checks on every worksite. 15 patrol officers in the team of close to 60 Earthworks Surveillance and Patrol Officers cover a total distance of 360,000km – or nine trips around the earth – each year. That’s an average of 135 worksites a single patroller visits each month, said Mr Ou. Checks are frequent – for sites close to gas pipes, checks are conducted daily. For transmission cables over 66kV, checks are conducted three times a week. There are many bases to cover. All contractors need to submit a notice of commencement of earthworks (NCE) seven days before they are scheduled to begin. They are also briefed on precautions and mitigation measures onsite by ESP officers. SP is also consulted on high-risk earthwork sites to ensure nothing is missed. This minimises the risk of damage.   During site meetings conducted by ESP officers, all requirements are covered, and SP patrollers ensure they are followed. Senior officers like Mr Ou will also join patrols or attend briefings to ensure contractors get clear and complete guidance. Part of the team: SP Earthworks Surveillance and Patrol officers join site briefings and guide contractors and workmen on how to best to protect critical cables and underground pipes during works. Most contractors do take compliance seriously, says Mr Ou. “Sometimes, it is subcontractors that just don’t know the procedures, or shift the location of their work, and it poses a risk,” he said. The team’s diligent checks and contractors’ compliance with regulations minimises that risk. This protects both our critical infrastructure and the workers at these sites. Getting the job done right requires a “high-trust” environment, and the same openness and teamwork demanded by sports, says Mr Ou, who plays football in an amateur league on weekends. He also conducts monthly huddles with his team, and encourages all officers regardless of rank to speak freely if they have suggestions or spot anything amiss. “I recognise it is important to have each other’s back when working on something critical, and to come together as a team. “Everyone has a part to play and can add value.” — 11 July 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing Engineer, 27, shares how she is undaunted by male-dominated energy industry & climbs the ranks
