LEC (Levelised Energy Cost)
The average cost of production per kilowatt hour electricity, calculated over the full life-time of the generating asset. The net present value method is used to discount future costs with the average cost of capital (WACC).
Life cycle analysis (LCA)
Methodology to establish a products' total environmental impact during its life cycle, from raw material extraction, through manufacturing processes and usage, to waste management, including all transportation and energy consumption.
LTI (Lost Time Injury)
Work-related accidents resulting in absence longer than one day, and accidents resulting in fatality. Commonly expressed as LTIF, or Lost Time Injury Frequency, the number of such accidents per 1 million hours worked.
Marginal security that the holding of a derivative position must pledge to cover the credit risk of its counterparty (OTC or exchange).
The order in which production capacity at plants is used.
The electric output that a plant delivers to distribution networks, i.e., gross capacity less the energy used by the plant itself. Measured in MW (Megawatt).
The capacity that a generator is designed for. This concept is used mainly for electricity generation power plants, e.g., hydro power plants and wind turbines. Measured in MW (Megawatt).
The Nordic electricity exchange. Started in Sweden and Norway in 1996.
Collective term for nitrogen oxide, nitrogen dioxide and similar nitrogen compounds.
Net Promoter Score, or NPS, is a score ranging from -100 to 100 that measures the willingness of customers to recommend a company's products or services to others and is used to determine the customer's overall satisfaction with a company and loyalty to the brand.
A series of standards that can be used as a basis for an occupational health and safety management system.
Over the Counter. Trading outside of exchanges (directly or via brokers) in physical and financial contracts.
Two or more individuals or customers can connect and transact directly, without going through a company.
Converting electricity to heat using electric boilers combined with hot water storage. With Power-to-Heat systems, the excess power generated primarily from renewable energy can be utilised later as district heating.
Primary energy is the form of energy that is accessible directly from the original sources. Vattenfall uses the interpretation applied by Eurostat and IEA. This means that all fuels are assigned a primary energy content corresponding to its heating value. Uranium is assigned a primary energy content corresponding to the heat released in the power plant. Solar, wind and hydro power are assigned a primary energy content corresponding to the extracted electricity (or heat).
Someone who both produces and consumes electricity.
Renewable energy sources
Non-finite energy sources such as hydro power, biomass, wind, the sun, ocean waves and geothermal energy.
The process of replacing older wind power stations with newer ones that either have a greater capacity or more efficiency, which results in a net increase of power generated.
Refers to the volume of water stored in a reservoir which on a specific occasion can be used for hydro power generation. Reservoir levels vary during the year depending on precipitation and production.
SAIDI (System Average Interruption Duration Index)
An index of average power interruption times within electricity distribution. Measured in terms of interruption duration per customer and year.
SAIFI (System Average Interruption Frequency Index)
An index of average power interruption frequency within electricity distribution. Measured in terms of the number of power interruptions per customer and year.
A greenhouse gas over 15,000 times more potent than CO2 which is commonly used for electrical insulation.
Svensk Kärnbränslehantering AB (The Swedish Nuclear Fuel Management Company) – responsible for handling radioactive waste in Sweden.
A market in which trading is conducted for immediate delivery.
A financial instrument that is a combination of a spot and forward transaction – a type of financial swap agreement.
Electricity generated via a heating process, such as a gas turbine or a steam process in a coal or nuclear power plant (compare combined heat and power).
TPI (Third party integration)

A product or service which is provided to customers who then brand the product themselves and resell it as their own.
- Power is energy per unit of time
- Power output is measured in watts (W)
- 1 kW (kilowatt) = 1,000 W
- 1 MW (megawatt) = 1,000 kW
- 1 GW (gigawatt) = 1,000,000 kW
- Energy is power multiplied by time
- 1 kWh (kilowatt hour) = 1 kW in one hour
- 1 MWh (megawatt hour) = 1,000 kWh
- 1 GWh (gigawat hour) = 1,000,000 kWh
- 1 TWh (terawatt hour) = 1,000,000,000 kWh
- ktonnes (kilotonnes) = 1,000 tonnes
- Mton (megatonnes) = 1,000,000 tonnes
