GTS and LDCs facilitate the supply of green gas

As future energy supplies will be based on sustainable practices, the Netherlands is committed to renewable sources such as wind, sun and green gas/biogas. Sustainably produced gas will represent an essential element of the future energy supply. Network operators consider a volume of 3 billion m3 green gas by 2030 to be realistic.

We want to do our utmost to facilitate the development of sustainably produced gas.

One of the issues faced by potential green gas producers is how much scope there is for feeding green gas into the Dutch gas network. The demand for gas is heavily dependent on the seasons: demand is high in winter and low in summer. Furthermore, demand in urban areas is greater than in rural areas and the demand for gas is high during the day and relatively low at night.

Green gas is produced from fermentation, a continuous process and, consequently, a continuous supply. This can lead to an imbalance between supply and demand in summer.

The network operators have developed a working method together with the aim of creating sufficient feed-in capacity for green gas producers at the lowest social costs. The image below shows several measures offered jointly by network operators:

Each case is examined to see whether there is sufficient scope available to feed in: if sufficient feed-in capacity is available then the measures will not be required. A structural restriction to feeding-in will trigger an investigation into which technical measures can expand the feed-in capacity at the lowest social costs.

In addition to the measures that GTS is offering in collaboration with the local distribution companies, GTS also intends to offer its own individual measures.

In this presentation you will find more information about possible technical measures.

Becoming a green gas injector

We have described below how you can become an injector into GTS's network.

A connection with GTS
You are intending to produce green gas and want to feed this gas into the public gas network of the local distribution company (LDC) or the national network operator (GTS). In order to do so, you can contact us via the form below.

This application form asks you to provide, in addition to your name and address, the desired green gas production location and injection capacity with the associated gas quality.

The process of becoming a green gas injector for GTS involves the following three elements:

  1. Feasibility study
    We assume that you will need an SDE+ subsidy (incentive scheme for sustainable energy production) for producing your green gas supply. In order to apply for the SDE+ subsidy, you will need to submit a (positive) feasibility study from the network operator to the Netherlands Enterprise Agency (RVO). GTS will produce this study if you have requested this via the application form mentioned above.
    You will receive global information regarding technical feasibility and delivery time for the connection from us within 10 days of your request or we will let you know if we need more time.
  2. Investment Agreement
    If, on the basis of the feasibility study, you make a definite decision to invest, we will send you an Investment Agreement regarding implementation of the connection. The Investment Agreement signed by you represents your instructions to GTS to build the connection. We will then discuss with you, as soon as possible, the building and construction of the connection pipeline.
  3. Grid Connection Agreement
    You will conclude a Grid Connection Agreement with us before the connection is brought into use.  This contains all the necessary technical arrangements for the gas supply (quantity, pressure, quality).

Statutory requirements for the injection of green gas

The statutory provisions and conditions for injecting (green) gas into the national grid are relevant to you. The injection code gas TSO provides a broad outline of these and more details, in respect of quality, composition and pressure, are contained in the Ministerial Decree on gas quality.

Gas measurement
As mentioned, you yourself are responsible for performing verifiable measurements which should comply with the “functional requirements for fiscal metering”. Doing so guarantees that both the design and management of the measurements will be standardised as far as possible. The requirements for this are set out in the accompanying document.

Other information

Green gas certificates (Vertogas)
Green gas certificates were created to promote trading in green gas. Green gas certificates make it possible to separate the physical green gas product from its use.  It offers consumers the opportunity to ‘green’ their activities by purchasing green gas without being physically connected to a green gas producer.

Vertogas is responsible for issuing green gas certificates. The certificates issued by this company guarantee the origin of the green gas. They give assurance to buyers that the green gas purchased is of the same quality as natural gas. The certificate also provides information about the raw materials from which the green gas has been produced.

Timing measures

It is very important for the timing of your investment to be in line with the timing of the work planned in for our pipeline. The lead time for a connection point is, on average, around 2.5 years and therefore we would recommend making contact with GTS at the earliest possible stage.
