GREECE

1.   Types of gas:

The following types of gas are distributed in Greece:






—


gases in group H (2H) of the 2nd family (natural gas), and










—


gases in all three groups of the 3rd family (liquefied petroleum gas):






—


commercial butane (3B) comprising at least 85 % by mass of butane and butene, with butane as the main component;










—


commercial propane (3P) comprising at least 85 % by mass of propane and propene, with propane as the main component; and










—


a mixture of butane/propane (3P/B), also called LPG mixture, comprising propane and butane in various proportions. For example, LPG on the Greek market comprises 80 to 90 % by mass of butane and the rest of propane.








2.   Legislation:

Natural gas:






1.


Ministerial Decision No Δ3/Α΄/οικ.6598/20.03.2012 on the technical regulation on internal natural gas installations operating at pressures of up to 500mbar (Government Gazette, Series II, No 976)










2.


Amendment No Ε-143/2023 of the Management Code for the National Natural Gas System (ESFA) (9th revision) (GG II 5773)










3.


Regulation (EU) 2015/703 establishing a network code on interoperability and data exchange rules (Annex - Conversion factors between reference conditions)




Liquefied petroleum gas:






1.


Joint Ministerial Decision No 31856/11.08.2003 on the technical regulation on LPG installations in buildings (other than factories and small-scale industries) (GG II 1257)










2.


Joint Ministerial Decision No 300/2005/18.09.2006 on LPG specifications (GG II 1483).

Information on toxic components contained in the gaseous fuel


Information on toxic components is not available to the distribution system operator. Natural gas distributed in the territory of the Slovak Republic is odourised and does not have toxic or poisoning effects. A component – odorant – used for this purpose is toxic only to aquatic organisms.

(1)  Not regulated.

(2)  In special circumstances and not more than 2 hours it may contain double quantity but the daily average value must be less than 6,5 mg/Nm3.

(3)  It concerns installations of liquefied petroleum gas except industrial and craft industries.

(4)  Comments:
For ‘Supply pressure at the inlet of appliances’, data in parentheses refer to elevated low pressure gas networks.

(5)  Not specified

(6)  Based on the definition of LPG found in the Liquefied Petroleum Gas Market Regulations (Legal Notice 249 of 2008) as amended

(7)  Not regulated

(8)  Not applicable

(9)  These data are not analysed by the distribution network operator and are therefore not available.

(10)  This is the input pressure for appliances that are connected to the distribution network; appliances connected to pressure vessels are also used in the Slovak Republic.
