Our Storage Code was firstly published on January 1, 2005.

The Storage Code went through several extensive modifications reflecting mainly changes of the relevant legislation, comments from storage users, experiences from operation of the underground gas storage and development of the gas storage market.

Last, approved by ERO's decision, wording of the Storage Code is effective as of August 22, 2023.

Currently valid Storage Code including all its annexes is attached here.

The Price list you can download here.

The Storage Code is fully in compliance with the Guidelines for Good Practice for Storage System Operators (issued by European Regulators’ Group for Electricity and Gas, March 23, 2005).
