Become a bio-methane feeder?
When can I start feeding bio-methane into the GTS network?
In principle, decentralised feeding of bio-methane will take place, in the first instance, in the network with the lowest pressure level that is available near to the location of the production installation. This will usually be the Local Distribution Company's (LDC) network, which is usually operated at a pressure of 8 bar, 4 bar or even lower. This means that injection can be carried out at the lowest cost. The compression costs and investment in the compression unit are relatively low and the connection costs are also considerably lower than those involved in connecting to GTS’s high-pressure network.
However, feeding into the GTS network may be appropriate. That is the case if the demand in the LDC network is too low for the quantity of bio-methane produced at certain times in the year. This may be the case when the weather is warm and particularly at night, when there are no, or very low, sales to households. Because bio-methane is mainly produced in rural areas and sales are limited there in comparison to urban areas, this situation occurs regularly. It is of essential importance that the potential for feeding gas into the natural gas network is considered at an early stage when making a decision about the place of operation!
A connection point with GTS
A new connection to the gas transportation network means that we will ensure that there is a connection point at the nearest point of the gas transportation network where sufficient capacity and pressure are available. In practice this will be a split-Tee with a valve, to which you can connect the feeder pipe. You are responsible for ensuring that the feeder pipe and connection comply with all the relevant regulations, statutory requirements and standards..
You will go through the following process in order to become a bio-methane injector with GTS.
In order to apply for the SDE+-subsidy (incentive scheme for sustainable energy) it is necessary to be able to submit a feasibility study put together by the network operator concerned to Agentschap NL . The applicant must submit a request to GTS for the performance of the study, providing the following details:
- Name, address, town of the planned production location
- maximum bio-methane injection capacity in kWh/hour
Within 10 days of the request you will receive an indication of the price and technical feasibility and a global delivery time for the connection, or you will receive an indication of when you can expect this information from us. In the event of several applications within one network area, the applications shall be assessed separately as long as no investment agreement for a connection has yet been signed.
No costs are associated with a feasibility study.
Application form for a new connection point
You must fill in an application form so that we know, as precisely as possible, what you expect from us as a customer. We will use this application form as the input for creating a Quotation Request Agreement. It is therefore important that this form is completed clearly and comprehensively. You can download the form on this page.

Quotation Request Agreement
You can instruct us to start a study into the connection possibilities by signing the Quotation Request Agreement and paying the accompanying offer fee.
As soon as we have received back from you your signed application form and, if applicable, Quotation Request Agreement, we will start a study into the connection options. As the outcome of the study we will send you an Investment Agreement. This will include a time schedule. When you sign this Investment Agreement and send it back to us, you are giving us instructions to carry out the new connection point.
Building/construction of the connection point
After instructions have been given, we will start the building and construction of the connection point. One condition is, of course, that you have also contracted transport capacity. If you do not yet have any transport capacity, a transport capacity booking will have to be carried out in parallel with the connection process. For this purpose you will generally use the services of a shipper who participates in the gas transport as a recognised programme responsible party.
You will conclude a Connection agreement with us before the connection point is brought into use.
Bio-methane certificates (Vertogas)
Bio-methane certificates were created to promote trading in bio-methane. Bio-methane certificates make it possible to separate the physical bio-methane product from its use. It offers consumers the opportunity to ‘green’ their activities by purchasing bio-methane without being physically connected to a bio-methane producer.
Bio-methane certificates guarantee purchasers that the bio-methane they have bought is actually ‘green’. The certificates contain information about the quality and source of the energy form.
Vertogas is responsible for issuing bio-methane certificates. The certificates issued by this company guarantee the origin of the bio-methane. They give assurance to buyers that the bio-methane purchased is of the same quality as natural gas. The certificate also provides information about the raw materials from which the bio-methane has been produced.
Since November 2011, bio-methane certificates have also shown whether the biomass used complies with the international criteria for sustainability according to NTA 8080. The NTA 8080 verification mark guarantees consumers that the bio-methane purchased has been produced from sustainable biomass.
Conditions for feeding of bio-methane
You will find here the provisional scope for feeding bio-methane into GTS’s 40bar (RTL) network.
These conditions are provisional and may be tightened on the basis of experience, including observations made from the test project involving injection into the GTS network by Natuurgas Overijssel (ROVA Zwolle).
The fiscal metering by a bio-methane feeder needs to comply with the function requirements for fiscal metering. This ensures standardization of metering both in design and operation. The requirements are available as GTS_OSM-20-E (GTS Functional Requirements Fiscal Metering).
