(1) For gas appliances connected to the (natural) gas network (second family):

Article 11 of the Gas Act (the Gas Act relates to the public gas network) reads as follows:

1. Gas fed into the gas transportation network or delivered by network managers at exit points shall meet requirements to be laid down by ministerial order. Such requirements may be different for feed-in and exit points and depending on energy content, pressure level and region.

2. The requirements referred to in point 1 above shall in any event cover the safety, efficiency (including in any event minimisation of social costs), reliability and sustainability of the transportation and use of gas.

Point 2 in particular is taken to mean that, irrespective of the provisions of the ministerial order, safety and efficiency must be maintained in the supply of gas or when changes are made to that supply. In this connection, the technical capabilities of the existing appliances and the existing gas networks are of overriding importance.

Classification of the gas supply of the (natural) gas network:

From the perspective of gas appliances, there are three main groups of public gas networks in the Netherlands: 1. The H gas network, comprising regional systems, some of which have their own specifications for gas supply conditions. Approximately 80 large-scale consumers are connected to the H network and an RNB (Regionale netbeheerders) [Regional network managers] H network of large-scale consumers. 2. The G gas network which involves switching between three stable supply conditions: (a) the G supply conditions which apply at the present time throughout the G gas network; (b) the G+ supply conditions which will not start before 2022; (c) the E supply conditions which will not start before 2030. It is expected that these supply conditions may occur within the lifetime of gas appliances to be newly connected in 2018. No explicit statutory gas supply requirements, such as exist for G and G+ conditions, have as yet been drawn up for E supply conditions. They will be drawn up when the E supply conditions are actually going to be implemented. They will involve the supplied gases being suitable (within the meaning of Article 11 of the Gas Act) for appliances in appliance category I2,E with a nominal appliance pressure of 20 mbar. 3. The L gas network which is intended for export and from which no gas is supplied within the meaning of Regulation (EU) 2016/426 on the territory of the Netherlands.

In addition, the networks are classified in three sub-levels depending on pressure level: 1. the HTL [hoofdtransportleiding] (main transportation pipeline) network; 2. the RTL [regionale transportleiding] (regional transportation pipeline) network; 3. the RNB network. Gas can be supplied on the basis of any pressure level. The gas supply conditions may differ from one pressure level to another.

For other gas appliances: There is no specific legislation on gas supply conditions for gases other than those supplied through the (natural) gas network, such as propane and butane and mixtures thereof. The parties involved usually make arrangements under private law for the supply of such gases, often involving voluntary standards. For information purposes, this annex indicates the standard values often used.

The bandwidth chosen will allow category I2,E appliances to be used safely and efficiently. It will be laid down in the Gas Quality Order in due course.

(3) For gas appliances connected to the (natural) gas network (second family):

No specific statutory requirements for the sum of the C1 to C5 content. However, there are requirements for the maximum propane equivalent under certain supply conditions in the G gas network.

(Explanation of propane equivalent (PE): unit of content of higher hydrocarbons in gas, calculated as the sum of the proportions in mol % of the higher hydrocarbons in the gas, each higher hydrocarbon being assigned a weighting factor of the number of carbon atoms in the higher hydrocarbon in question minus one, divided by two.)

The requirements are:

G conditions: maximum of 5 mol % propane equivalent (PE)

G+ conditions: maximum of 8,1 mol % propane equivalent (PE)

E conditions: no specific statutory requirements. The admissible content in E supply conditions has not yet been determined. The content chosen will allow category I2,E appliances to be used safely and efficiently. It will be laid down in the Gas Quality Order in due course.

(4) Second gas family, G gas network, G conditions: The following restriction applies to the content of carbon dioxide (CO2) if at least 99 mol % of the gas is made up of methane, carbon dioxide, nitrogen (N2) and oxygen (O2) and more than 6 mol % is made up of CO2.

Maximum CO2 content is the minimum of:

* 10,32 – 0,72 * N2 content – 0,87 * O2 content, and

* 10,56 – 0,746 * N2 content – 1,01 * O2 content,

where the contents are expressed in mol %.
