Media Release SP Develops Future Energy Leaders Through First Energy Managers Programme And Industry Scholarships Singapore, 2 November 2018 – Singapore Institute of Power and Gas (SIPG), as the centralised training institute for the power and gas sectors, announced today the successful completion of its first Energy Managers Programme (EMP). The pioneer cohort of 19 energy sector professionals was recognised in a ceremony during Singapore International Energy Week 2018, witnessed by Dr Tan Wu Meng, Senior Parliamentary Secretary, Ministry of Trade and Industry and Ministry of Foreign Affairs. The programme, which is under the SkillsFuture Leadership Development Initiative, is designed to build a pipeline of strong leaders for the energy sector as they address issues and opportunities in today’s transforming and disruptive landscape. Building on its inaugural run, SIPG is opening its programme to participants from ASEAN utilities and other international companies in the energy value chain, curating a broader range of experiences, perspectives and real-world applications. Mr Peter Leong, Principal of SIPG, said, “We customised this programme to help energy industry managers hone their well-rounded leadership skills through blended learning in the classroom and field trips to companies in Singapore and overseas. They have personally benefitted from networking with peers from across the value chain. They have also gleaned insights on driving advancement and innovation amidst the rapid industry disruption, in order to serve all consumers better.” Spanning five months from February this year, the programme’s first participants were emerging leaders from generation companies and SP Group. Through workshops, dialogues with senior leaders from the energy sector and government, as well as a learning trip to China, the participants were exposed to pertinent challenges the industry faces, in Singapore and around the region. They also gained valuable insights from individual coaching sessions and working on action projects. Mr Neo Bing Hui, Senior Operations Engineer, YTL PowerSeraya Ltd, said, “The Energy Managers Programme (EMP) has helped broaden my views of the industry in general, providing a different perspective of how challenges can be viewed in the energy sector. After going through EMP, I have gleaned more insights on my leadership style and how I can effectively improve communication with my team mates. I am excited to start applying what I've learnt from this programme.” The pressing need to inspire the energy sector to groom the next generation of energy leaders is why the Energy Market Authority is supporting the programme. Its Chief Executive, Mr Ngiam Shih Chun, said: “For the energy sector to embrace new opportunities and challenges, there is a need to engage and develop tomorrow's energy leaders. They will need to be agile and adopt a growth mindset to lead their organisations forward. EMA supports SIPG in playing a crucial role in providing a programme to grow our future energy leaders.” Nurturing engineering talent In developing future engineering talent, SP Group also awarded two Energy-Industry Scholarships to students from institutions of higher learning – Ms Choo Wei Ming, 19, from Ngee Ann Polytechnic and Mr Muhammad Syahiran bin Jamal, 20, from Singapore Polytechnic. SP Group’s Chief Human Resource Officer, Mr Ng Seng Huwi, presented the scholarships to Wei Ming and Muhammad Syahiran, at a ceremony during the Youth@SIEW event earlier today. The scholarship serves to nurture talent for the energy sector and support students with a passion for engineering in achieving academic and career aspirations. They will join SP Group when they complete their studies. About SP Group SP Group is a leading energy utilities group in the Asia Pacific.

More solar means more investment: SP More infrastructure needed to handle two-way flow when supply rises in future By RONNIE LIM ronnie@sph.com.sg SINGAPORE Power (SP), which handles electricity and gas transmission and distribution here, will need to make a “significant investment” in additional infrastructure to handle a two-way power flow in the electricity grid when supply from intermittent generation sources, including solar energy, ramps up in future, said its CEO Wong Kim Yin. Speaking to BT on the sidelines of the Electricity Roundtable yesterday, Mr Wong said that while SP’s existing infrastructure can handle the just-announced increase this week in the current cap on intermittent generation sources from 350 megawatts to 600 MW, SP will have to boost its infrastructure if this is further upped beyond 1,000 MW later. The new 600 MW cap announced by the government represents around 10 per cent of current peak electricity demand in Singapore of 6,000 MW. The cap Mr Wong: Power market liberalisation has brought capital inflows of over $78 billion in last five years is to ensure there is sufficient electricity reserve (from the gencos) to back up the intermittent energy sources and ensure power system stability. Mr Wong explained that presently power is transmitted via copper cables, which are stronger or thicker nearer the power source, like a power station, with this “stepped down” as it progresses down the chain from sub-stations to industries or homes. “The existing transmission system is already two-way in that homes with solar panels already sell back some of their generated electricity to the grid,” Mr Wong said. But when supplies from such intermittent sources, like solar energy, increase significantly, SP will need to make “a significant investment” to build up system capability to handle this. But he declined to give specifics, like the investment dollars needed, at this stage. Already, the Housing Development Board is stepping up its use of solar energy in flats here, while other new projects like the Singapore Sports Hub are also adopting solar panel use to meet some of its electricity needs. This is why government this week said it is preparing the power system here to “effectively incorporate solar energy as it becomes commercially viable”. Apart from raising the current cap on intermittent generation sources here, regulator Energy Market Authority has also launched a public consultation on a regulatory framework for such power sources. In his presentation, Mr Wong – who as senior managing director of Temasek Holdings previously had handled its divestment of the three biggest gencos here – said that liberalisation of the power market here has proven successful. “Market liberalisation here has attracted capital inflows of over $78 billion into the power sector over the last five years. And SP alone has spent capex of $5.4 billion to improve pipelines and the power grid, with this raised from capital markets,” he said. On this, David Wong, director and chairman of Energy Market Company’s audit committee, noted that while gencos have invested in more efficient gas-firing plants to generate electricity competitively, surging fuel prices have led to a steady increase in the spot or wholesale electricity price over the last decade. “Compared to 2003, the wholesale electricity price has almost doubled to $179 per megawatt hour in the first three quarters of 2013,” he said, adding that economic growth has fuelled electricity demand, putting upward pressure on prices. This in turn has attracted investment in new plants, and “an outcome of this is that the wholesale electricity price has in actual fact softened, and is currently 19 per cent lower than last year”.
