Gas supply during the redevelopment of the Tyra gas field 2019-2024

The offshore Tyra gas field in the North Sea is shut down from September 2019 to winter 2023/2024.

During the first 3 years of this period, consumers in Denmark and Sweden will primarily get their gas supply from Germany and biogas fed into the gas system combined with gas from the Danish gas storage facilities. From October 2022 Norwegian gas through the Baltic Pipe connection and biogas are the primary sources of gas supply.

Questions and answers related to the redevelopment period

The redevelopment will restore the Danish processing and export center of gas

Tyra has for decades processed 90% of the Danish gas production. The redevelopment of Tyra ensures continued production from Denmark’s largest gas field, and will protect the supply of gas to Danish and Swedish consumers.

During what period of time will Tyra be shut down for redevelopment?

According to TOTAL, the Tyra gas field will be shut down from September 2019 to winter 2023/2024. Read more about the project on TOTAL's website.

Will biogas alleviate the supply situation?

Yes – The production of biogas is expected to contribute to improving the supply situation. Prognoses show that the amount of upgraded biogas fed to the gas grid will cover an increasingly large part of Danish gas consumption.

What are the consequences to Danish and Swedish consumers during the redevelopment period?

Most likely, neither Danish nor Swedish consumers will be affected by that. The primary source of supply during most of the period of reconstruction will be gas from Germany in combination with withdrawal from the Danish gas storage facilities, with Norweigan gas being dominant from October 2022 with Baltic Pipe. If the market players use the capacity of the gas system optimally, there will be sufficient capacity in the gas system to supply the Danish and Swedish market.

Will there be gas enough?

Yes - if full capacity is provided to the storage facilities in due time – and that is to be ensured by the market players - there will be sufficient gas. In combination with gas imported from Germany, the gas storage facilities ensure the supply of gas to the Danish and Swedish consumers, and - when filled to capacity – the storage facilities hold almost 0.8 billion cubic metres of gas, corresponding to approx. 25 per cent of the annual consumption of Denmark and Sweden combined.  

The connection to Germany ensures a sufficient level of security of supply. We will depend on the German supplies during the redevelopment period, so situations may arise in which the system is put under pressure – especially in situations of low temperatures coinciding with high consumption.

Will the gas storage facilities contain enough gas in winter in case of an emergency situation?

Energinet will make extra reservations of gas volumes in the gas storage facilities during the period of time when Tyra is under redevelopment. One of the measures will be to buy extra emergency volume to cover the consumption of the protected customers during 30 cold days. 

What are the consequences in terms of the gas price?

The gas price may rise in peak-load periods, which may  be seen as a negative effect from the point of view of the gas consumers. But higher prices will also draw gas to the Danish and Swedish market, thus improving the situation of supply, if the gas system comes under pressure.

As a rule, the price of gas in Denmark and Sweden will follow the market price in the remaining part of Europe but, in situations of cold weather and bottlenecks developing towards Germany, the price of gas will increase in Denmark and Sweden.

Has Energinet considered shipping liquid natural gas (LNG-gas) to Denmark?

Yes – but cost-benefit calculations show that the solution of sailing gas to Denmark will not pay off.

What about maintenance work on the transmission system during the period?

Energinet has planned for maintenance work on the transmission system to be carried out in periods before or after the redevelopment of the Tyra gas field.

Will there be problems in terms of the supply?

The gas system will return to a situation of relying on one primary source of supply from Germany supplemented by biogas and natural gas from the Danish storage facilities. The connection to Germany was expanded in 2013, but if the winters during the Tyra redevelopment period turn out to be unusually strenuous, the supply may be challenged.

What has Energinet done to secure the supply in the Tyra redevelopment period?

As owner of gas infrastructure, Energinet Gas TSO manages the security of supply by providing sufficient capacity in the gas system, monitoring the supply situation and informing the authorities and the market players of the situation.

Besides, Energinet Gas TSO supports efficient use of the infrastructure through market rules. Below examples give an idea of the changes made recently:

  • A guide to the seasonal gas storage level is provided to give shippers a tool to calculate how to meet the Danish and Swdish consumption for the rest of the season: Read more about the Safe Storage Level
  • The balancing system plays an essential part in the market rules. To secure the right incentives for the market players to transport gas to Denmark, the price caps on imbalance prices have been removed. This will enable the prices to develop freely on the market according to the supply situation.
  • A new price formula will be implemented for the market players to take the right actions to prevent the gas market to reach the crisis level of emergency and to secure the use of emergency gas only as the last resort.

Finally, to ensure sufficient capacity on a cold winter’s day, Gas Storage Denmark has made a minor investment to increase the capacity of the gas storage facility in Lille Torup to improve the withdrawal capacity.

Will the German gas be compatible with my gas stove?

Yes – Your gas stove is prepared for receiving gas qualities within the limits of the gas specification applying to all types of gas supplied into the Danish and Swedish gas system.

If - nevertheless - the unexpected situation arises in which there is not enough gas for a period of some duration - what will happen then?

It is Energinet's goal to always provide a clear and intelligible picture of the situation at hand and the challenges that may arise.

If, in spite of all the best efforts and preparatory measures being applied, a situation arises in which the market must give in on upholding the supply to the consumers, Energinet is under the obligation to supply gas to all of the so-called protected consumers for a minimum of 30 days. Ordinary Danish households are considered protected consumers.
