Until recently, development plans for LNG terminals were part of an overarching approach to setting up supply chains. A natural gas producer and an established supplier typically exchanged long-term contracts for annual quantities of gas sold by the producer to the supplier.
This led to a whole chain put in place to convey gas to its end market through the construction of a series of liquefaction plants, regasification facilities and LNG tankers.
Deregulation in the European market and strong growth in LNG trade around the world have reshaped the conventional linear approach. We are now witnessing wide-ranging changes in every aspect of the gas supply chain as operators become increasingly specialised.
In this new environment, Elengy aims to draw fully on its role in helping open up and expand the LNG market by pooling its established experience to guarantee its customers safe, effective services while developing new projects and increasingly 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.

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.
A technology that enables a single fuel source to produce both thermal energy (heat and/or cold) and electricity at the same time.
A power station that comprises a gas turbine generator whose exhaust powers a boiler. The steam from the boiler then drives a turbo-generator.
Operator’s obligations concerning the physical characteristics of the natural gas being delivered (pressure, temperature, etc).
Liquefied Natural Gas
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.
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.
