grtgaz ensures gas transit to a variety of european destinations. in total, it transports over 1. 5 times france' s consumption every year .
a joint study carried out by ademe (agence de l' environnement et de la maîtrise de l' energie), grtgaz and grdf. 30 october 2014
* engie, societe d’infrastructures gazieres (held by cnp assurances and caisse des dépôts) and grtgaz signed preliminary memorandum of understanding for the acquisition of elengy (a wholly - owned subsidiary of engie operating lng terminals) at 100% by grtgaz (the french natural gas transmission operator, owned 75% by engie and 25% by sig) .
this is why grtgaz has decided to set up industrial high - performance clubs, events designed to provide a group of consumers with a forum for exchanges on common issues. grtgaz regularly invites industrial firms connected to the transmission network, as well as future customers who would like to have discussions with other industrial companies and share their feedback on different topics .
as a provider of climate solutions, grtgaz is thereby involved in the reduction of greenhouse gas emissions in a sustainable way, providing incomes and local jobs that cannot be relocated, and fuels a virtuous cycle in a circular economy. thanks to its technical expertise, grtgaz acts as a facilitator on the value chain of this green gas that comes from our lands .
by encouraging the emergence of renewable gases produced in france, and their local use in industry and transports, grtgaz places its network at the service of the energy transition for the country .
grtgaz' s ambition is to become the european natural gas transmission operator of choice by offering the safest and best transmission services, and to make france the leading gas trading hub in europe .
from their projected energy scenarios for 2030 and 2050, adme and grdf joined forces with grtgaz to assess the current situation internationally with regard to advances and prospects for power - to - gas .
europe imports over 60% of natural gas it consumes and that figure should exceed 80% in 2030. security of supply is a major issue. grtgaz helps relieve facilitating the flow and exchange of natural gas across europe .
grtgaz owns and operates the longest high - pressure natural gas transmission network in europe. it is involved in the management of networks in germany. in europe and worldwide, it provides assessment and consulting services in the field of gas transmission .
first of all, atrt6 tariff takes into account the reprocessing of charges transfer due to repair maintenance, renovation and replacement (the “3r” operations), between the distribution networks and grtgaz following the deliberation of the cre published in march, 10 th 2016 .
as off 1st april 2018, according to article l. 452 - 1 of the code of energy and cre’s deliberation of 22nd february 2018, grtgaz is in charge of the collection of storage compensation among shippers using its network, and its transfer to storage operators .
the grtgaz network is sized to accept part of the hydrogen and 100% of the synthesized methane. in all cases, the gas produced is fully neutral as regards its carbon footprint, because it replaces an equivalent amount of gas extraction and increases our energy independence .
the cre published on december, 15 th 2016 its deliberation approving tariff of natural gas transmission systems of grtgaz and tigf, the “atrt6”, entering into force from april, 1 st 2017 for 4 years and yearly updated. this new tariff frame allows grtgaz to face major goals during this time frame without overcharging its transmission costs: achieve the single marketplace in france in 2018, promote natural gas and develop future energy solutions. this deliberation contains tar nc article 30 (1) (b) information (regulation (eu) 2017 / 460) .
the limitation of the “niveau de tarif régional » (ntr). the nrt is now limited to 10 (previously up to 29), in order to preserve competitiveness of the most remote sites from grtgaz’ network and to prevent from any termination of their connection to its network .
engie plans to increase transport capacity to be able to respond to the growing natural gas market as well as to connect up new combined - cycle power plants and new lng terminals. the development projects undertaken by grtgaz will mean an investment of approximately €3 billion between 2010 and 2019 .
* for the shareholders of grtgaz and elengy, this planned acquisition responds to both european gas infrastructure challenges and market player needs. the market is currently subject to infrastructure consolidation where very large players are integrating several gas chain businesses, in particular lng terminals and gas transmission networks, says engie
generating value from gas - electricity coupling: the main topics for 2017 will concern the technical evaluation of power to gas and the optimisation of its business model, the development of multi - energy modelling tools, delivering expert advice to regional authorities and assessing the interest of grtgaz assets participating in rte systems services .
the natural gas transport on the principal network consists in, for grtgaz, removing the gas provided by a shipper in one or more entry gas points in france and in delivering it in one or more exit points. at each entry and exit points correspond a regular tariff. the main tariff terms are as follows :
beyond energy prices, what levers can be used to optimize the performance of these industrial sites? by providing access to the wholesale market, optimizing processes, choosing equipment and implementing high - performance technical solutions, grtgaz supports industrial consumers in their efforts to use natural gas with optimal efficiency, in both environmental and economic terms .
several technological solutions are mature and already in use on a number of sites. some large industrial groups already make use of these solutions: general electric, siemens, atlas copco and cryostar (subsidiary of linde), among others. the finalisation of the contractual arrangement that would enable grtgaz to make use of this electricity is the only obstacle that remains .
the complementary aspects of the electricity and gas transport networks open new perspectives for the construction of a global energy system that is smarter and oriented to the integration of renewable energies. moving beyond existing cooperative projects on the security of supply, grtgaz and rte intend to draw benefit from the digital revolution to build a response to the regional issues of energy, transport and climate .
to make matters worse, the nuclear fleet, france’s main source of electricity for heating, is mired in uncertainty and will be subject to inspections that could halt reactors for indefinite periods. earlier this year, unexpected nuclear closures caused gas demand to skyrocket, creating shortages. while the government this summer requested grid operator grtgaz sa to intervene and buy fuel to replenish supply, the uncertainty is roiling trading .
a bottleneck is highly likely in the southeast when lng supply at the two fos terminals is low, grid operators grtgaz and transport et infrastructures gaz france sa said in a winter outlook in may. in the event of a 10 - day cold spell not anticipated by the market, french consumers will suffer shortages without quick deliveries of lng, potentially “in volumes never seen before, ” the operators said .
when solar - or wind - based electricity generation is insufficient, gas - fired power plants are the best option to take over and generate top - up electricity while ensuring the lowest emissions and the highest level of efficiency (55% compared to 35% for a coal - fired power plant). grtgaz contributes to the performance of gas - fired power plants by supplying them with gas in a reliable and a flexible manner, particularly at the time of peak demand .
on the basis of the 2030 - 2050 blueprint developed by the l’ademe under which 50% of the electricity generated should stem from green sources, grtgaz estimates that by 2050, the power to gas solution will produce between 15 and 20 twh of renewable gases per year, which will be injected or stored in the network during periods with considerable excess production levels. once the energy has thus been transformed into gas, it will benefit from all the strengths of natural gas transmission: economical, flexible, discreet and safe .
to meet the specific needs of each consumer, energy efficiency has become a factor in a company' s competitiveness. in the future, supply management considerations will go hand in hand with the development of high - performance and energy - efficient consumption practices. technology, purchasing, operations, regulations, taxation... all of these areas are increasingly, and inextricably, at the heart of discussions held by industry on how to develop its production resources and methods. grtgaz regularly chairs industrial performance club meetings dedicated to a group of consumers so that they may discuss problems related to their sector (glass, agri - food, etc .) or specific subjects (metering, supply, etc .) .

the group controls the largest gas transport network in europe. the network is managed by dedicated subsidiaries in france, germany, austria, spain and slovakia .
infrastructures in spain (medgaz), germany (megal), austria (bog) and slovakia (eustream), through stakes held there by the group .
we are currently studying the generation of power from pressure energy lost during the expansion of natural gas at several points on our network, which heralds a promising future for the generation of carbon - free electricity. an explanation .
to transport large quantities of natural gas over great distances, it is compressed and kept under high pressure. the aim is to reduce its volume and, thereby, the diameter of the pipelines. subsequently, a certain amount of energy is released and lost at every point of the network where pressure has to be reduced (known as expansion) to adapt to downstream conditions .
the energy thereby released is also recoverable, clean (as it is carbon - free) and usable in substantial proportions. in fact, an accessible deposit study carried out in 2015 identified around 20 sites that could house a generator powered by the flow of gas instead of the conventional expansion system. this operation would produce almost 100 gwh of electricity per year, which represents 25% of the energy consumed by the network' s electric compressors .
the transport network, natural gas and renewable gases contribute efficiently to the energy transition by reconciling reductions in emissions with energy security and competitiveness .
find out more about our energy solutions with a future and in particular fuel - gas conversion, biomethane, bio - ngv and the innovative power to gas solution. each of these four technological innovations prepares what we currently call the third gas revolution .
many industrial sectors, including metallurgy and the paper and food industries, use boilers and furnaces .
these are large consumers of natural gas. for them, optimizing gas usage is essential .
in addition to providing the benefits of a dynamic wholesale market, and competitive prices compared to other energies such as fuel oil, gas offers clear advantages in the current technological and regulatory environment .
air quality regulations are becoming increasingly strict, in particular with the transposition of the ied (industrial emissions directive), the implementation of the french particulate matter reduction plan [
plan particules
], and the ceilings imposed on france by the nec (national emissions ceilings) directive. liquid fuels will be distinctly limited by these regulations, and dust requirements will be stricter than before (fuels concerned include biomass, coal, and fuel oil). natural gas, on the other hand, does not emit soot or dust when burned. it generates 30% less carbon dioxide (co2) than fuel oil and 45% less than coal, less nitrogen oxides (nox) and very little sulphur dioxide (so2), the cause of acid rain. it should be noted that natural gas has an emission limit value of 100 mg / nm3 of nox, for new and existing boilers, as well as in continuous emissions monitoring for certain configurations .
gas also brings an economic advantage in the field of taxation, for industrial companies that owe tgap [ french tax on polluting activities ]: the current rates for sulphur oxides (sox) emissions and total airborne particles tripled in 2013. the rate for nitrogen oxides (nox) rose from €160. 80 / tonne to €164. 18 / tonne, after having tripled in 2012 .
in the field of energy efficiency, 2012 saw a vote for a new eed (energy efficiency directive) which should go into effect starting in 2014. among the measures adopted, one that should be noted is the requirement for large businesses to conduct an energy audit every four years. this could mean a real opportunity for improving industrial processes and reducing energy costs .
1 / monitoring of energy and water consumption. this monitoring is the first action that should be implemented. it enables precise determination of the distribution of energy between different user stations, as well as making available means to detect any excessive variations in consumption .
2 / periodic inspection of boiler performance, via regular combustion analysis, efficiency calculations, and if necessary, adjustment of settings. mandatory for boilers over 400 kw, this inspection is essential. optimizing combustion or installing an o2 - co regulator can increase ncv efficiency by 0. 5% to 2% .
3 / optimization and implementation of performance - enhancing processes such as blowdown management, heat recovery during boiler purges, and installation of a condenser or economizer. installing an economizer can often mean a 4% increase in yield .
4 / optimizing the steam network, e. g. by insulating pipes, setting up preventative maintenance on traps, or using flash steam. for example, it is considered that 20% of steam traps prove to be defective each year. and a leak in a trap can result in 5 to 20 kg / h of steam lost .
while these are the
classic
ways of finding cost savings, each boiler is often a special case. as such, the choice of which solution (s) to implement depends on the specifics of the site, and on how the steam is produced and used .
energy efficiency is now a competitiveness factor. in the future, consideration of supply management will go hand in hand with the development of high - performance, energy - efficient uses. whether it be technology, purchasing, use, regulations, or taxation, all of these components are increasingly, and inextricably, at the core of industry thought on how to develop tools and production methods .
biomethane is a fuel gas that is produced by repurposing organic matter derived from various sectors, including agriculture, industry, catering waste, community waste, and gas derived from non - hazardous waste landfills (nhwl) .
the digestion of organic matter produces biogas which can be processed by combustion to provide heat and / or electricity. this biogas can be upgraded to the same quality as natural gas, and is then called “ biomethane ”. once it is purified and odorised, it can be injected into gas grids .
the production of biogas generates a residue called digestate. a natural organic fertilizer, it can be spread on agricultural lands as a substitute for fossil - based mineral fertilizers .
biomethane is clean and has excellent virtues; it is great for our land and brings a new perspective to our energy. its production is part of the development strategy for renewable energies in france since 2011 .
the ademe 4 (french environment & energy management agency) anticipates that 500 to 1, 400 sites could inject between 12 and 30 twh / year of biomethane into the grids around 2030. . this projection is an objective set by the state in the law no. 2015 - 992 of 17 august 2015 relating to energy transition for green growth, which says that 10% of gas consumed in 2030 should be from a renewable source .
an analysis of the biomethane life cycle carried out by grdf (french gas network distribution) and the ademe 5 demonstrated that the development of the biomethane sector could prevent the emission of 750, 000 tonnes of co 2 for the year 2020 alone, with 4 twh / year of biomethane used. cumulatively, the emission of over 2 million tonnes of co 2 equivalent would therefore be avoided thanks to the development of the biomethane sector at this time. in other words, for each megawatt - hour (mwh) of biomethane produced, injected and consumed, savings of 188 kilogrammes of co 2 equivalent would be made .
the green gas initiative member companies are convinced that gas and gas infrastructures play a key part in reaching the european objectives of carbon emissions at a reasonable price for society and consumers, and work together in order to identify specific courses of action until 2050 .
production sites, new connections to gas networks, production and projects: all the information about biomethane in france .

this platform provides energy production and consumption data on national and local levels. use of these multi - energy and multi - operator data will facilitate the development of local authority energy policies and contribute strongly to innovation. it will also contribute to the efficiency of stakeholders in the energy system to engage in more pertinent activities with regions .
the new energy network data platform will be enriched over time with data from other electricity and gas infrastructure operators .
international: this agreement aims to identify areas of synergy to enable joint bids for tenders or to develop international business opportunities mixing electricity and natural gas .
the conversion of electricity into gas which is subsequently injected into the networks would enable excess electricity generated by renewable sources such as wind turbines or photovoltaic cells to be put to good use. this conversion principle, called power - to - gas, is currently being studied in a number of european countries .
the study considers that this technology should be fully operational in france by 2030. with a penetration of electrical energy from renewables greater than 50% by 2050, power - to - gas would enable between 20 and 30 twh / year of renewable gas to be injected into the existing networks thus constituting a long - duration solution for storing the excess .
by using the large storage capacities of the gas infrastructures (in pipes and underground storage facilities), the conversion of electricity into gas is the subject of research in a number of european countries such as germany and denmark. power - to - gas involves converting renewable electricity into hydrogen by electrolysing water, hydrogen which can then be injected into the natural gas network as is or after a methanisation stage which consists of combining it with co2 to convert it into methane .
the development of intermittent electric renewables such as wind turbines and photovoltaic cells requires solutions to be found for optimising their insertion into the energy networks. if production is too low, scalable standby production capacities must be available; conversely, production greater than demand requires the development of storage capacities and / or conversion of the excess .
recommendations to the authorities and various actors for the growth of this new distribution channel in france .
at times, the electricity generated by wind farms on land or offshore, and by solar plants, cannot be fully consumed or exported .
because there is no storage solution, the units are shut down, or the electricity is lost to avoid saturating the networks. the technological innovation featured in the power to gas demonstration plant provides a solution for storing and using the surplus electricity, by transforming it into gas .
how is that possible, you might ask? quite simply by transforming the electricity into hydrogen through water electrolysis. the hydrogen can then be combined with carbon dioxide (co 2) as and when necessary to obtain synthesized methane, via a methanation process .
above all, power to gas is an exceptional lever for the energy transition, encouraging development of renewable energy sources .
by helping to supply ngv with a neutral carbon footprint, power to gas makes an efficient contribution to the energy transition. the green gas thus produced, which emits lower levels of co 2 and particulates than petrol or diesel fuel, also constitutes a viable alternative to fossil fuels for transport, with the effect of reducing air pollution levels .
power to gas provides many advantages for local authorities: gas production stimulates the implementation of infrastructure and industrial equipment in the departments, thus leading to production of industrial facilities, which in turn create activities and jobs in the areas concerned .
the first power to gas project linked to the french gas transmission network, called jupiter 1000, will be put up at fos - sur - mer (bouches - du - rhône, 13). the demonstration plant is scheduled to come into service in 2018 with a power rating of 1 mwe. it will be the first installation on that scale in france .
the launch of a power to gas demonstration plant does not involve ground - breaking technology that requires many long years of development. the feedback from experience and the studies stemming from analysis of existing plants will enable refinement of the model via the jupiter 1000 project, leading to considerable improvements in the levels of technical and economic performance, and to validation of all the environmental qualities .
first experiment in france at a megawatt (mw) scale, i. e. a production level equivalent to the annual consumption of about 150 families ;
at a time when greenhouse gas emission and energy efficiency regulations are being tightened and taxes are rising, gas represents an advantage that contributes to the competitiveness of industrial companies .
gas not only lets users benefit from a dynamic wholesale market and a competitive price in comparison with other energy sources such as fuel oil, it also offers undeniable advantages in today' s regulatory and technological environment .
1. following the emergence of more stringent air quality standards, due in particular to the transposition of the industrial emissions directive, the implementation of particle reduction plans and the caps imposed on france under the national emissions ceilings directive, gas has undoubtedly become the alternative solution. restrictions on liquid fuels will be tightened under these regulations and dust requirements will be more stringent than in the past (biomass, coal and fuel oil are concerned). whereas, the burning of natural gas emits neither soot nor dust. this process emits 30% less co 2 than fuel oil and 45% less co 2 than coal, as well as less nox and very little so 2, which causes acid rain. it is worth noting that both for new and existing boilers as well as in continuous emissions monitoring for certain configurations, natural gas has an emission limit value of 100 mg / nm 3 of nox .
2. with regards to tax and in the case of industrial companies that have to pay the french' general tax on polluting activities' (tgap, taxe générale sur les activités polluantes), gas represents a financial advantage as the current rates for sox emissions and total airborne particles were trebled in 2013. 3. with regards to energy efficiency, 2015 saw the introduction of the energy efficiency directive. consequently, large companies must now undertake an energy audit every four years. this audit represents a real opportunity to improve a company' s industrial processes and lower its energy costs .
1. monitoring of energy and water consumption. this is the first course of action to be taken in order to accurately identify the distribution of energy among the various user stations and to install the resources necessary to detect any variations in the level of use. 2. periodic monitoring of boiler performance results by regularly analysing combustion, calculating efficiency and, if necessary, adjusting settings. this monitoring process is essential and, in fact, mandatory for boilers with a rated output of more than 400 kw. optimising combustion or installing an o 2 - co regulator can improve ncv efficiency by 0. 5% to 2% . 3. optimisation and installation of performance - enhancing processes and equipment such as micro - modulating burners, condensers or economizers, and the management of purges, including, if possible, heat recovery during purging. 4. optimisation of the steam network by insulating pipes, carrying out preventive maintenance on purge valves or by using flash steam. for example, it is estimated that 20% of purge valves prove to be defective each year. however, a leak in a purge valve can result in 5 to 20 kg / h of lost steam .
while these savings are' conventional' solutions, each boiler room is very often unique. furthermore, the solution (or solutions) to be retained depends on the characteristics of the site and the manner in which steam is produced and used .
after implementing an exhaust heat recovery system, the gas solution offers an additional gain of ...
price difference between the two types of fuel *, global saving (excluding tax) ...
from 35% to 38% , i. e. around €320, 000 per year (not including savings on taxes such as the ticp, tgap, etc. )
* hypothetical energy prices (approximate market prices, february 2016): ultra - low - sulphur heavy fuel oil: €210 / t (or €18. 6 excluding tax / mwh ncv) natural gas: €12 excluding tax / mwh gcv
several industrial sites, boiler rooms & glasshouses are choosing the cogeneration to optimize their processes. more economical and ecological, this solution enables them to produce heat and electricity simultaneously from natural gas .
there are many possible ways to use the heat provided by the cogeneration: heating, hot water, etc. they can use this electricity to supply their industrial site or sell it to power the electrical grid .
moreover, as the recovery of co 2 emissions from the cogeneration boosts the photosynthesis, glasshouses also benefit from plants’ productivity gains .
it is an emblematic project that paves the way for more projects of this kind thanks to its contribution to balancing the electricity system by becoming a major component within smart grids, tomorrow' s flexible and integrated energy system .
connecting decision makers to a dynamic network of information, people and ideas, bloomberg quickly and accurately delivers business and financial information, news and insight around the world .
as southern france emerges from months of searing heat, the country is scrambling to avert getting caught out by a winter cold snap again .
natural gas that should be going into storage is being used to offset reduced hydropower output and to cool people down, meaning the nation may not have enough fuel to warm everyone up come winter. storage levels are near a five - year low, while an infrastructure bottleneck that propelled the country’s gas prices to the highest in the world last winter hasn’t been resolved .
“french gas storage levels remain dangerously low, ” said elchin mammadov, an analyst at bloomberg intelligence in london. “we are likely to see major gas price volatility, particularly in the southern hub area” that lacks interconnecting links .
to meet increased summer demand, traders are bringing in more liquefied natural gas. supplies from two import terminals near marseille reached the highest level for the july 1 - aug. 15 period since 2011, according to cargo - tracker paneurasian enterprises inc .
but gas in a storage site that serves the south, which last winter became almost half - empty even before a cold snap squeezed supplies in january, is still below a five - year average. storage facilities across france were 68 percent full as of aug. 27, gas infrastructure europe data show. stockpiles in southern france are 77 percent full, the lowest for the time of year since 2013 .
storage sites are typically refilled through october, leaving a few more weeks to top them up as the heatwave recedes and cooler days arrive .
“we still have time, ” melissa stark, managing director for energy at accenture plc, said by phone. “there is a lot of lng on the market. ”
last january, lng arrivals at fos were three times lower than initially planned, sending gas prices above those paid by japan, the world’s biggest buyer .
to promote lng imports, fosmax lng sas, operator of the fos cavaou terminal, said in june it cut tariffs to unload cargoes from oct. 1. and the market already anticipates an lng wave as the global glut swells .
“the elephant in the room is the onset of lng into northwest europe as further projects come onstream, ” said nick campbell, an energy risk manager at inspired energy solutions. french gas suppliers may think “the better risk management option would be to utilize lng, not storage. ”
french electricity for the fourth quarter of this year jumped to a record on aug. 17 after nuclear regulator asn said that electricite de france sa must review all nuclear components made by an areva sa foundry by the end of next year. benchmark next - month gas for northern france gained for a sixth week through aug. 25. although edf said output won’t be impacted, markets feared a repeat of last year’s squeeze .
“last year gas shortages were driven by really cold weather in the south – and there has not been much in the way of infrastructure changes to rectify constraints that only really bite during extreme weather, ” said trevor sikorski, head of natural gas, coal and carbon at energy aspects ltd. “the same extreme weather would likely lead to the same extreme prices if it was to happen again. ”
