MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 JANUARY TO 31 MARCH 2022 Singapore, 30 December 2021 – For the period from 1 January to 31 March 2022, electricity tariff (before 7% GST) will increase by an average of 5.6% or 1.33 cents per kWh compared with the previous quarter. The increase this quarter is due to higher fuel costs. Around 95% of Singapore’s electricity is generated using imported natural gas at prices indexed to oil prices. Over the past few months, a confluence of recovering economic activity, severe weather events, and a series of gas production outages have sent global energy market prices significantly higher. These factors have raised electricity prices in many markets. For details on the components of the electricity tariff, please refer to Appendix 1: Breakdown of Electricity Tariff. For households, the electricity tariff (before 7% GST) will increase from 24.11 to 25.44 cents per kWh for 1 January to 31 March 2022. The average monthly electricity bill for families living in HDB fourroom flats will increase by $4.70 (before 7% GST) (Appendix 3: Average monthly electricity bills of domestic consumers). *before 7% GST SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). The tariffs shown in Appendix 2 have been approved by EMA. Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: a) Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. b) Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. c) Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management, retail market systems as well as market development initiatives. d) Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.

1,000 isi rumah di Tengah daftar bagi sistem alat dingin berpusat HAMPIR 1,000 isi rumah telah mendaftar bagi sistem alat dingin berpusat (CCS) di 8,000 flat Bina-Ikut-Tempahan (BTO) di bandar Tengah. Pemilik rumah yang memilih sistem cekap tenaga ini dijangka meraih penjimatan sekitar 15 hingga 20 peratus kos pendahuluan dan sebanyak 30 peratus dalam kos kitaran hidup, kata SP Group, yang menguruskan sistem itu. CCS merupakan salah satu daripada ciri pintar yang akan dilaksanakan di Tengah, bandar yang disebut sebagai ‘tenaga pintar’ yang digerakkan oleh kecerdasan buatan (AI). Di bawah sistem CCS, air dingin akan disalur ke rumah dari unit penyejuk yang dipasang di bumbung Blok HDB yang terpilih. Menurut, SP Group, ini adalah cara yang lebih menjimatkan tenaga berbanding sistem hawa dingin konvensional. Sistem ini akan memanfaatkan tenaga suria yang dihasil oleh panel solar di bumbung blok HDB. Para pengguna juga dapat memantau dan menangani penggunaan tenaga rumah mereka melalui aplikasi MyTengah. SP juga akan memasang huraian tenaga pintar yang lain untuk meningkatkan kesedaran masyarakat dan mengalak cara hidup gaya lestari. Papan pemuka digital akan dipasang JIMAT TENAGA: Satu aplikasi mengawal suhu unit alat hawa dingin dipapar di MyTengah Experience Centre. – Foto BH oleh CHONG JUN LIANG di lobi lif setiap blok perumahan, yang mengesan penggunaan utiliti dan kesannya terhadap alam sekitar. “Papan eko ini akan mengongsi petua-petua mengurangkan penggunaan elektrik dan air, disamping mempromosikan budaya gaya hidup lestari melalui pelbagai pertandingan penjimatan utiliti antara blok,” kata SP group. Penduduk dan orang ramai boleh mengunjungi Pusat Pengalaman My Tengah baru di Hub HDB di Toa Payoh untuk mengetahui lebih lanjut mengenai huraian mesra alam lain yang dilaksanakan di Tengah. Pusat pengalaman ini akan dibuka dari 8 pagi hingga 5 petang pada hari Isnin hingga Jumaat.

Singapore planning a subterranean future as it faces space constraints Singapore SPACE-STARVED Singapore has expanded outwards by building into the sea and upwards by constructing highrises but planners are now looking underground as they seek new areas for growth. The nation has carefully managed its rapid growth in recent decades to avoid the problems faced by other fast developing Asian metropolises, such as overcrowding and traffic chaos. But with its population of 5.6 million expected to grow steadily in coming years, authorities are now considering how to better use the space below the streets. Singapore has already built an underground highway and state-of-theart air conditioning system, but is now looking to house more facilities beneath the surface in order to optimise land use above it. “We need to consider options for putting critical infrastructure underground,” said Abhineet Kaul, a Singapore-based public sector specialist at consultancy Frost & Sullivan. “We have an increasing need for industrial, commercial, residential and green space on land in Singapore.” Source: The Business Times © Singapore Press Holdings Limited. Permission required for reproduction. According to a draft development plan released in March, authorities want to put utilities, transport as well as storage and industrial facilities underground in order to free up land on the surface. There are as yet no plans to put housing underground, however. Three-dimensional technology will be used to produce subterranean maps, with three pilot areas targeted initially, according to the Urban Redevelopment Authority, which created the development plan. Singapore is the latest city to try to make use of subterranean space. Finland’s capital Helsinki has tunnels housing car parks, shopping malls and even swimming pools, while Montreal in Canada has a so-called “Underground City”, a tunnel network connecting key points. In a report commissioned by Samsung about what the world will look like in 50 years, experts predicted the appearance of “earthscrapers” – like an inverted skyscraper burrowing downwards for many storeys – in an attempt to save space in overcrowded cities. Singapore’s main method of expansion has been land reclamation from the sea, which has increased the country’s area by over a quarter to 720 sq km, with most growth happening since independence in 1965. But reclamation has become more expensive as it moved to deeper waters, while countries that used to sell sand to Singapore have stopped exports due to environmental concerns. Unregulated sand mining erodes beaches and riverbanks, affecting wildlife and removing natural barriers to flooding, and dredging the seabed can damage ecosystems, green groups say. Moving facilities underground has advantages beyond saving space, including reduced use of air conditioning which could save energy in Singapore’s tropical climate. Still, building underground in Singapore poses challenges – construction is difficult beneath an already urbanised environment while new projects will compete for space with existing subterranean facilities. “Underground construction normally involves the blasting of rocks and if it’s in the downtown area, you will not be able to use blasting,” said Chu Jian, a civil and environmental engineering professor at the Nanyang Technological University (NTU). One of the most ambitious underground projects so far in Singapore is a system that pumps chilled water through pipes to cool buildings around the city’s popular waterfront district of Marina Bay. Buildings which use the centralised system – rather than relying entirely on their own air conditioners – have reduced energy consumption by around 40 per cent, said Foo Yang Kwang, the chief engineer of Singapore District Cooling, SP Group, which is behind the project. Reduced energy use has enabled the buildings to slash their annual carbon dioxide emissions by 34,500 tonnes, which is equivalent to taking 10,000 cars off the road, he said. Other current subterranean facilities in Singapore include South-east Asia’s longest underground expressway, measuring 12km, the metro train, an ammunitions depot, and rock caverns beneath the seabed which are used to store oil. NTU, one of the city’s top institutes of higher education, is considering building labs and even classrooms underground, according to Prof Chu. But he said shifting things underground is just one way of coping as Singapore grows: “It is the next frontier, but not the final frontier. I am confident that we will be able to figure out other ways to create new space.” AFP
