In line with the public service missions of Elengy, the commitments of the GDF SUEZ Group and its desire to establish balanced and constructive relations with all its customers and the stakeholders (local authorities, residents, associations, government departments), Elengy policy revolves around the three cornerstones of sustainable development – economy, environment, and the social aspect – and is based on the following principle :
Developing and anticipating changes in the LNG markets by consolidating Elengy’s position as one of the leading LNG terminal operators in Europe through the CAP Elengy business project;
Ensuring the safety of facilities and people and reducing the environmental impact by pursuing a continuous development approach and maintaining the integrated management system, evaluated regularly by an internationally recognised tool (isrs7© DNV), enabling the performance of management to be assessed in terms of health, personal and industrial safety, the environment (ISO 14001 certification) and quality (ISO 9001 certification);
Developing the attractiveness, effectiveness and social cohesion of Elengy by building up an Elengy corporate culture and rallying the personnel around shared values and a shared identity, based on sustainable development.
As a key player in opening up a rapidly changing market, Elengy uses its experience as an LNG terminal Operator to guarantee safe, high-performance services to its customers, develop new projects and provide innovative solutions.

Natural gas is principally composed of methane (CH4) and is found in natural reserves. As a primary energy source, it offers many qualities, and is the cleanest fossil fuel.
It is appreciated for its high calorific value, ease of use, and environmentally-friendly composition.
Natural gas is odourless, but an artificial odorant is added to enable detection in the event of a leak.
When natural gas burns it does not emit dust, soot or smoke, producing only water vapour and carbon dioxide, much like human breath, which is then transformed back into oxygen by plants. It is the most energy-efficient of all fossil fuels on the market.
An explosion of natural gas can only occur if the following three factors occur simultaneously:
Every care is taken in at LNG terminals to prevent these three things occurring at the same time.
For reasons of national security, our sites may not be visited by the public.

Corresponds to aggregated Shipper send-out allocations in kWh 25°C at the interface between the LSO and the TSO.
This information is provided at 7h00 LT for the preceding gas day.
Amount of gas in kWh 25°C belonged by the shippers in the tanks of the LNG terminal at the beginning of the day.
Corresponds to the aggregated Shipper daily send-out nominations in kWh 25°C at the interface point between the LSO and the TSO (PITTM).
Provisional data for each gas day of the coming month are provided on the 25th of the former month when the monthly programs are published by the LSO.
Then the provisional data for a given gas day is replaced by a definitive value at 18h00 LT on the day before.
Corresponds to the available commercial capacity of the LNG terminal, i.e non subscribed capacity, expressed as the daily average of the month, in kWh/J at 25°C.
This information is updated daily.
Difference between Total Firm Capacity and the amount of booked capacity.
A technology that enables a single fuel source to produce both thermal energy (heat and/or cold) and electricity at the same time.

Contract between the Operator and a Shipper, stating the reception, storage and regas conditions for LNG cargoes delivered by the Shipper to an LNG terminal.
High-pressure, large-diameter facilities linking connecting points with neighbouring networks, underground storage facilities and LNG terminals, to which are connected the regional transport networks and a number of industrial consumers and retail networks.
Responsible for operating an LNG terminal. The Operator delivers services under LNG Terminal Access Contracts signed with Shippers.
Share of the Total Firm Capacity that the terminal Operator has agreed on with a Shipper in a terminal access contract.
Corresponds to the total commercial capacity of the LNG terminal (including the already subscribed capacity), expressed as the daily average of the month, in kWh/J at 25°C.
This information is updated daily.
