The launch of the electricity futures market in 2015 facilitated the entry of more independent retailers, hence increasing retail competition and bringing benefits to consumers. The electricity retail market considerably expanded with the entry of six new retailers in 2016. They were (i) I Switch Pte Ltd, (ii) Sunseap Energy Pte Ltd, (iii) Best Electricity Supply Pte Ltd, (iv) Sun Electric Power Pte Ltd, (v) Charis Electric Pte Ltd, and (vi) Environmental Solutions (Asia) Pte Ltd.
In 2016, the market share of SP Services Ltd – the sole retailer of electricity to households and small non-contestable electricity consumers – stood at 30.1%. Tuas Power Supply Pte Ltd had a 13.4% market share, while that for Senoko Energy Supply Pte Ltd stood at 13.0%. These were closely followed by Seraya Energy Pte Ltd (12.9%) and Keppel Electric Pte Ltd (10.4%). SembCorp Power Pte Ltd and PacificLight Energy Pte Ltd accounted for market shares of 9.8% and 7.4% respectively, with the remaining 3.0% distributed among the smaller and newer entrants.
contestability & sector
Singapore’s total electricity consumption rose by 2.3% from 47.5 TWh in 2015 to 48.6 TWh in 2016. Contestable Consumers (CCs) made up the bulk of consumption, accounting for 73.8% of the total consumption in 2016. The rest were from non-CCs.
The majority of CCs’ consumption was for Industrial-related activities (54.7% or 19.6 TWh), followed by the Commerce & Services-related sector (38.1% or 13.7 TWh).
On the other hand, Households comprised the bulk (59.5% or 7.6 TWh) of consumption by non-CCs. Another 31.5% (4.0 TWh) was consumed by the Commerce & Services-related sector.
Total electricity consumed by Households rose by 5.1% from 7,220.9 GWh in 2015 to 7,589.4 GWh in 2016. About 59.0% (4,480.2 GWh) of total consumption was by public housing units. Private housing units and other types of residences, such as private shop-houses and quarters, accounted for the remaining 40.8% (3,098.7 GWh) and 0.1% (10.5 GWh) respectively.
The average monthly consumption of electricity by Households marginally increased by 1.5%, from 468.4 kWh in 2015 to 475.6 kWh in 2016. While public housing dwellings registered a 2.2% increase in average monthly electricity consumption to reach 383.9 kWh in 2016, that for private housing units fell by 1.0% to 725.0 kWh in 2016.
The average monthly electricity consumption of a 4-room public housing unit was 395.5 kWh in 2016. The average monthly electricity consumption of a 1-room/2-room and 3-room unit were 55.6% and 26.2% respectively, lower than that of a 4-room unit while a 5-room and executive flat consumed about 22.5% more.
End-users¹ consumption of NG declined by 2.6%, from 56,096.1 TJ in 2015 to 54,639.3 TJ in 2016. Industrial-related consumption, which comprised the bulk of NG’s end use (i.e. 86.3%), weakened from 49,214.8 TJ in 2015 to 47,133.7 TJ in 2016, catalysing the reduction in overall NG consumption.
Consumption by Transport-related users also registered a decline of 21.8% to 468.6 TJ in 2016. In contrast, the Commerce & Services-related sector and Households’ consumption of NG rose by 18.7% and 1.6% to reach 4,380.2 TJ and 2,547.8 TJ respectively.
¹ Final end-users or consumers exclude those involved in power generation (as Main Power Producers or Autoproducers) and oil refining.
Households use NG in the form of town gas, which is manufactured by City Gas and subsequently sold to households and other end-consumers. The average monthly household town gas consumption fell by 2.9%, from 80.7 kWh in 2015 to 78.3 kWh in 2016.
In 2016, the average monthly town gas consumption of a 4-room public housing unit was 77.9 kWh. A 1-room/2-room and a 3-room unit consumed about 31.8% and 16.9% respectively less than that of a 4-room dwelling while a 5-room and executive flat consumed 6.2% more.
Total oil consumption amounted to 9,814.1 ktoe in 2015, about 9.4% higher than the 8,970.4 ktoe recorded in 2014. Industrial-related activities accounted for almost three quarters (i.e. 73.9% or 7,256.6 ktoe) of total oil consumption while the Transport-related sector consumed about a quarter (i.e. 2,450.8 ktoe).
The Commerce & Services-related sector consumed 81.7 ktoe (or 0.8 %) of oil, while the remaining 25.0 ktoe of oil was consumed by Households.
Singapore’s Total Final Energy Consumption (TFEC) increased by 6.4%, from 14,474.7 ktoe in 2014 to 15,402.5 ktoe in 2015.
Almost two-thirds (67.0% or 10,322.5 ktoe) of TFEC was accounted for by the Industrial-related sector. This was predominantly in the form of Petroleum Products (7,256.6 ktoe). Consumers in the Transport-related and Commerce & Services-related sectors accounted for 17.4% (2,675.4 ktoe) and 10.9% (1,672.9 ktoe) of end use consumption respectively. The Transport-related sector consumed mainly Petroleum Products (2,450.8 ktoe), while the Commerce & Services-related sector consumed mostly electricity (1,503.0 ktoe). Households accounted for 4.6% (705.7 ktoe) of total energy consumption, which was primarily in the form of electricity (620.9 ktoe) and NG by way of town gas (59.9 ktoe).
