These are enterprises that produce electricity but for whom the production is not their principal activity.

The Build Margin (BM) Emission Factor refers to the average CO₂ emissions emitted per MWh of net electricity generation by the most recently built five power plants. Singapore’s BM emission factor trends lower than the Grid Emission Factor as the most recently built power plants are generally more efficient as compared to the older plants.

A licensed cable detection worker is entitled to perform cable detection work. To minimise damages to electricity cables, it is mandatory to perform cable detection work prior to the commencement of any earthworks.

Cable detection work must be carried out by a licensed cable detection worker. He should inform or advise the earthworks contractor, who engaged him, of the location of the cables detected within the worksite.

Combined Cycle Gas Turbines are a form of highly-efficient energy generation technology that combines a gas-fired turbine with a steam turbine.The design uses a gas turbine to create electricity. It then captures the resulting waste heat to create steam which, in turn, drives a steam turbine to significantly increase the system’s power output without any increase in fuel.

Co-generation plants (also known as combined heat plants) are plants which simultaneously generate electricity and useful heat from a common fuel source. This improves overall thermodynamical efficiency.

Commercial Staff refers to Customer Accounts Manager, Business Analyst and those in Business Development, Sales and Marketing.

Corporate Service Staff refers to those in Finance, Human Resource, Legal, Administration, Information Technology and Corporate Communications

This refers to total electricity consumption by end users, including (embedded) consumption by Autoproducers.

This is paid to the generation companies and reflects the cost of power generation.

Energy products refer to products exclusively or mainly used as a source of energy. They include energy in forms suitable for direct use (for instance, electricity and heat) and energy products that release energy while undergoing some chemical or other process (such as combustion). The classification of energy products is based on the Singapore Trade Classification, Customs & Excise Duties 2022 (STCCED 2022 or HS 2022). STCCED classification adopts the ASEAN Harmonised Tariff Nomenclature 2022 (AHTN 2022). This is based on the 6-digit Harmonised Commodity Description and Coding System developed by the World Customs Organisation (WCO) for the classification of goods.

Engineer refers to Senior Engineer, Engineer, Executive Engineer, Principal Engineer, Shift Manager, Team leader and Deputy Team Leader.

Final energy consumption covers all energy supplied to the final consumer for all energy uses. It is usually disaggregated into the final end-use sectors such as Industrial, Commerce & Services, Transport, Households, and Others.

This refers to total natural gas consumption by end-users, excluding consumption for electricity generation.

Fuel mix refers to the proportion of fuel used for the generation of electricity. It is calculated using the output method which uses the amount of electricity generated and the corresponding type of fuel used to calculate the fuel mix for electricity generation. It takes the domestic fuel-to-electricity conversion efficiency of the generating plants and the type of plants used into account.

This is paid to SP Power Assets to recover the costs of transporting electricity through the grid

The Grid Emission Factor (GEF) measures average CO₂ emission emitted per MWh of electricity. This is the generation-weighted average CO₂ emissions per unit of net electricity generation by all generating power plants serving the system.

The scope of the Households sector includes all households in their capacity as final consumers.

The installed capacity of solar PV systems can be expressed in MWp or MWac.

MWp refers to megawatt peak, which is a typical measure of the installed nameplate capacity for solar PV systems. MWp represents the amount of electric power that can be produced by a solar PV system at its peak under Standard Test Conditions (STC). MWac refers to the Alternating Current (AC) capacity of the inverters used in solar PV installations.

MWp and MWac numbers differ because of conversion losses from DC (MWp) to AC (MWac). EMA adopts the derate factor of 0.77 as proposed by the National Renewable Energy Laboratory (NREL) to account for these losses, i.e. 1 MWp is estimated to be equivalent to 0.77 MWac.

These are enterprises that produce electricity as their principal activity.

Management refers to Chief Executive Officer and Head of Division/ Department/ Section.

This is paid to SP Services to recover the costs of billing and meter reading.

An Open Cycle Gas Turbine plant is a gas turbine power plant which discards the heat content of the exhaust gases exiting the turbine. This is as opposed to using a heat exchanger or recovered in a heat recovery steam generator (HRSG) as in a CCGT.

Others refer to other energy products that are not classified. These include Solar, Biomass, and Waste (such as Municipal Waste and Biogas). Municipal Waste is waste produced by residential, commercial and public services that is collected by local authorities for disposal in a central location for the production of electricity and/or heat.

“Others” include Assistant Technician, Semi-skilled Staff and other occupations not classified elsewhere.

“Others” refer to sectors or activities not adequately defined in SSIC 2022.

Own use in electricity generation refers to the part of electricity generated which is consumed by the auxiliary equipment of the generation plant (such as pumps, fans and motors) under normal operations.

Petroleum Products include Ethane, LPG, Aviation Gasoline, Motor Gasoline, Jet Fuel, Kerosene, Gas/Diesel Oil, Fuel Oil, Naphtha, White Spirit, Lubricants, Bitumen, Paraffin Waxes, Petroleum Coke and other Petroleum Products. The energy products and their corresponding HS 2022 codes under this category are:

Bishan, Bukit Merah, Bukit Timah, Downtown Core, Geylang, Kallang, Marine Parade, Marina East, Marina South, Museum, Newton, Novena, Orchard, Outram, Queenstown, River Valley, Rochor, Singapore River, Southern Islands, Straits View, Tanglin, Toa Payoh

Bedok, Changi, Changi Bay, Paya Lebar, Pasir Ris, Tampines

Ang Mo Kio, Hougang, Punggol, North Eastern Islands, Seletar, Sengkang, Serangoon

Boon Lay, Bukit Batok, Bukit Panjang, Choa Chu Kang, Clementi, Jurong East, Jurong West, Pioneer, Tengah, Tuas, Western Islands, Western Water Catchment

This is paid to the Power System Operator and Energy Market Company to recover the costs of operating the power system and electricity wholesale market.

The registered generation capacity of a generation facility is the maximum generation capacity approved by Power System Operator (PSO), and registered with Energy Market Company (EMC) to provide one or more of the following products in the Singapore Wholesale Electricity Market (SWEM):

1. Energy;

2. Reserve (Primary, Secondary or Contingency); and/or

3. Regulation.

Employees under Resident category refers to Singapore Citizens and Permanent Residents. Employees under Non-Resident category refers to foreigners.
