Developing new products/services and/or entering new markets.

Carbon Capture and Storage.

Methane; the main component of natural gas.

Normalised total of staff costs and other operating expenses less the costs allocated to investments and non-controllable energy costs.

Carbon dioxide; released when fuel fully combusts.

CO₂ equivalent; a metric measure that converts the amount of a GHG (like CO₂ or CH₄) into an equivalent amount of CO₂ with the same global warming potential (GWP). CO₂e is calculated by multiplying the mass of the GHG by its GWP. The GWP for CO₂ is fixed at 1 and the GWP for CH₄ is fixed at 28.

The actual temperature adjusted for wind velocity.

Environmental, Social, and Governance (ESG) is a set of considerations taken into account in the selection and management of holdings in companies. ESG encompasses matters like energy consumption, climate, availability of raw materials, health, safety, and governance.

Ministerie van Economische Zaken en Klimaat (Dutch ministry of Economic Affairs and Climate Policy).

FEED (front-end engineering design) is a phase in the life cycle of a project that precedes the actual implementation of the project. It is the phase after concept selection and consists of a detailed study and design phase that establishes the technical specifications of the project that form the basis for the detailed designs before construction or implementation begins.

Funds From Operations is the sum of the result after taxation of ordinary activities, depreciation, amortisation and impairments.

The controlled release of natural gas by burning it.

Floating storage regasification unit, a (dockside or offshore) vessel used to transport, store and regasify LNG on board.

Also called L-gas, this is natural gas of Groningen field quality, i.e. gas with a slightly lower calorific value than the high-calorific gas (H-gas) used internationally.

European Gas Research Group (the initialism comes from Groupe Européen de Recherches Gazières), a trade association of European gas companies, which focuses on research and development.

The Greenhouse Gas Protocol, the prevailing standard for reporting on GHG emissions, breaks down emissions according to their source. The emissions are divided into three categories (scopes), i.e. direct emissions from the company’s operations (Scope 1), indirect emissions associated with the company’s procured energy (Scope 2), and all other emissions arising in the company’s value chain, both upstream and downstream (Scope 3).

Green gas is biogas upgraded to the quality of natural gas.

Hydrogen produced in a climate-neutral way from renewable energy sources such as wind and solar power.

Gas that contributes to the creation of an insulating layer around the earth, causing it to warm up. The main greenhouse gases are water vapour, carbon dioxide, methane, nitrous oxide and chlorinated hydrocarbons.

Gasunie Transport Services

A Guarantee of Origin, or GO, is a certificate created alongside the production of renewable energy and so proof that the energy consumed is renewable.

Gasunie Deutschland

Gigawatt, a unit of electric power.

This stands for global-warming potential, i.e. the relative impact, molecule for molecule, of a greenhouse gas, taking into account how long it remains active in the atmosphere. The Intergovernmental Panel on Climate Change regularly updates the GWP based on the latest scientific insights.

High-calorific gas, i.e. gas with a slightly higher energy value than gas of Groningen field quality (G-gas/L-gas).

Hydrogen gas, which we generally refer to simply as hydrogen.

Incidents resulting in injuries to one or more employees of Gasunie and/or third parties as a consequence of carrying out work. Absence refers to work (or replacement work) not being resumed within one working day (24 hours).

Input tax is ‘VAT on our costs’, i.e. VAT that our suppliers have billed us for.

Total of tangible fixed assets, investments in joint ventures, investments in associates, and other equity interests adjusted for work in progress assets for which payment has yet to be received.

International Standardisation Organisation; an organisation that sets international standards.

Also called G-gas, this is natural gas of Groningen field quality, i.e. gas with a slightly lower calorific value than the high-calorific gas (H-gas) used internationally.

Leak detection and repair programme.

The mandate that a company is given (by the government and/or society) to perform its tasks.

Liquefied Natural Gas.

Liquid organic hydrogen carriers.

Megawatt, a unit of power equal to one million watts.

This ratio provides insight into the extent to which tangible fixed assets are financed by debt.

NOx is shorthand for nitric oxide (NO) and nitrogen dioxide (NO₂), gases that are emitted in all combustion processes and that contribute to air pollution.

An Open Season is an objective, transparent, non-discriminatory procedure that offers parties the opportunity to reserve capacity in a new infrastructure project.

Pseudo-G-gas is low-calorific gas made from high-calorific gas. This gas is of the same quality as Groningen gas.

Incidents resulting in absence, medical treatment, replacement work or fatalities.

The Greenhouse Gas Protocol, the prevailing standard for reporting on GHG emissions, breaks down emissions according to their source. The emissions are divided into three categories (scopes), i.e. direct emissions from the company’s operations (Scope 1), indirect emissions associated with the company’s procured energy (Scope 2), and all other emissions arising in the company’s value chain, both upstream and downstream (Scope 3).

Organisations or individuals with a certain interest (‘stake’) in the company.

In the Netherlands, this is understood to mean: the number of times gas transmission was interrupted because no, or insufficient, gas was able to flow through our infrastructure, irrespective of whether GTS in the Netherlands was able to supply sufficient gas to customers. In Germany, it is understood to mean the number of times that our infrastructure was unable to supply sufficient gas to customers. The scores attained by Gasunie in the Netherlands and Germany are added together to produce the total target score.

The Total Reportable Frequency Index (TRFI) is a measure for safety; the number of ‘reportable’ incidents (incidents leading to absence, medical treatment, alternative work or fatalities) per 1 million hours worked, assuming 1,600 working hours per FTE per year.

A transmission system operator is an entity entrusted with the transmission of energy in the form of natural gas or electrical power on a national or regional level, using fixed infrastructure. ‘Transmission’ is the term commonly used in reference to the long-distance transport of gas or electricity, especially within a country or region; when this energy crosses borders the term ‘transport’ is used.

Number of incidents involving gas leaks ((natural) gas, hydrogen, nitrogen, air) of over 14,000 m³ from a Gasunie-operated pressure holder with a rated pressure of 8 bar or higher.

Weighted Average Cost of Capital.
