Question 1: Electricity Market Table 1: Electricity consumption by sector (in Gigawatt hours) 2018 2019 2020 2021 2022 Household 7231.5 7681.3 8244.5 8277.7 7911 Industrial- related 21439.8 21463.9 20978.9 22293.1 22693.9 Source: Energy Market Authority, 1 June 2023 Extract 1: Rise in electricity prices Electricity prices will go up in Singapore as a result of higher carbon tax, a scheduled increase in the goods and services tax (GST) and rising energy costs. “The carbon tax is part of a suite of measures to support Singapore’s transition to a low -carbon economy, by steering consumers and producers away from carbon -intensive goods and services, holding businesses accountable for their emissions, and enhancing the business case for the development of low -carbon solutions,” said Energy Market Authority’s (EMA) spokesman. Power generation companies levied the carbon tax are expected to pass on some of the cost to electricity retailers like SP Group, which could then pass on these additional co sts to customers. Dr David Broadstock, senior research lead for energy transition at the National University of Singapore said the rising cost from the carbon tax could encourage innovation among companies to reduce the carbon content of the fuel used. At the same time, having more clean energy imports in the future could also have a bearing on the influence of carbon tax on future electricity prices, he added. Around 95 per cent of Singapore’s electricity comes from imported natural gas, which means Singapore cannot be fully insulated from developments in the global energy market. EMA said that natural gas which is the cleanest form of fossil fuel will remain the country’s main source of energy for the next decade, accounting for more than 50 per cent of Singapore’s energy mix by 2035, even as the Republic turns to cleaner technology to decarbonise the energy sector. Dr Broadstock expects global natural gas price s to continue to rise over the next three to four years due to geopolitical uncertainties like the Israeli -Hamas conflict affecting energy supply chains.

The tech industry is estimated to be responsible for up to 4 per cent of global greenhouse gas emissions, and this figure is sure to grow rapidly amid the rising use of data storage and processing. Singapore’s digital economy contributes to almost a fifth of its gross domestic product. Source: The Straits Times, 30 May 2024 Extract 3: Singapore’s energy transition towards a net-zero future Power generation accounts for about 40% of Singapore’s emissions today. The price we all pay for electricity generally does not reflect the “true costs” of producing it. To decarbonise our power sector, we will be importing electricity from the region and exploring low -carbon alternatives such as hydrogen. Hydrogen is often held up as a potential clean fuel of the future, because it can be burned like oil or gas but releases no climate -warming carbon dioxide – only water. The Singapore government will set up a Future Energy Fund to support infrastructure investments for our energy transition towards a net-zero future. Net zero refers to the balance between the amount of greenhouse gas that's produced and the amount that's removed from the atmosphere. It can be achieved through a combination of emission reduction and emission removal. Examples of energy transition infrastructure which could be supported by the Future Energy Fund include undersea cables to import low -carbon electricity as well as new hydrogen terminals and pipelines. These projects may involve nascent technologies or require high upfront capital expenditures, and furthermore exposed to significant commercial and geopolitical risks. The establishment of the Futu re Energy Fund ensures that the Government is ready to provide financial support to catalyse energy transition projects to secure low-carbon energy supplies to meet Singapore’s decarbonisation ambitions. This will better prepare our businesses and economy for a low-carbon future and allow Singapore to remain an attractive investment destination. Source: Energy Market Authority, 1 March 2024

Suggested answer: Similarity [1]: - Both household and industrial -related sectors showed an increase in electricity consumption from 2018 to 2022. Any of the differences below can be accepted [1]: - The electricity consumption of households increases at a faster rate than industrial-related sector. - The electricity consumption of households increases while the electricity consumption of industrial-related sector decreases from 2019 to 2020. - The electricity consumption of households decreases while the electricity consumption of industrial-related sector increases from 2021 to 2022. [2] (b) (i) With the use of a demand and supply diagram, account for the increase in electricity price and comment on whether it will continue in the future. Suggested answer: Explain the demand factor (2m): - From Extract 2: As more businesses digitalise and more artificial intelligence services are rolled out, there’s new investments in energy-intensive sectors such as advanced manufacturing and data centers. Since huge amounts of energy required to cool data centers , the growth of data center activity suggests an increase in demand for electricity from DD1 to DD2. Explain the supply factor (2m): - From Extract 1: Higher carbon tax, the rise in GST and rising energy cost → increase in unit cost of production of electricity → fall in unit profitability → producers are less willing and able to supply electricity → fall in supply of electricity from SS1 to SS2. Diagram (1m) [8]
