Netherlands

Grid connection

The general framework of grid connection is regulated in Article 12b of the Dutch Gas Act: Connection and Transport conditions DSO’s. In the specific case of biomethane injection into the grid, these conditions are extended with the ‘Supplementary Terms DSOs to biomethane suppliers’. These conditions including the supplements are part of the Connection and Gas Transportation Agreement between the DSO and the green gas supplier.

It is stated in the Dutch Gas Act that DSOs and TSO are obliged to provide connections to the grid. Specifically for the TSO it is a statutory task to manage, operate and develop the national transmission system, including storage in their grid. 

Cases for refusal of grid access

The biomethane has to meet the quality standards imposed by TSO and DSO. If not, access to the grid is denied. It is not regulated who should have grid access preference when several projects are willing to inject in a certain grid with limited transport capacity. Grid access might then be denied.

System usage fees (non-discrimination?)

Tariffs are regulated (biomethane treated as natural gas). The ACM (Autoriteit Consument en Markt) regulates the grid operators to ensure that transport quality is good, and that consumers pay a reasonable price. NMa sets the tariffs that grid operators are allowed to charge for transporting electricity and gas, and for connecting businesses and consumers to the network. The tariffs must have such a level that it is possible for the grid operator to make a reasonable return, yet is still stimulated to operate more efficiently still. Tariffs are non discriminatory and transparant, regulated with  the Dutch Gas Act.

Connection cost burden sharing

There is in the Netherlands no cost burden sharing of capital or operational costs related to green gas production or injection. The costs are borne by the production and upgrading plant owners. 

Network extension

Biomethane producer is responsible for pipeline to the grid, TSO/DSO is responsible for grid connection. TSO and DSO report bi-annually to the ACM in the Quality and Capacity document about their grid performance. Also the document contains the plans about keeping the level of quality and capacity in terms of investments in replacement and expension of their grids. 

The ACM can also request on the quality performance and characteristics of the grid in terms of age and materials. The information must also provide financial details about the status of the grid operators and their efficiency in terms of costs. 

On a small scale extension of gas grid infrastructure has been investigated for some individual cases (for the DSOs Rendo en Endinet).
