On 12 September 2011, the EU adopted a mandate to negotiate a legally binding treaty between the EU, Azerbaijan and Turkmenistan to build a Trans Caspian Pipeline System. This is the first time that the EU has proposed a treaty in support of an infrastructure project. The treaty will be concluded by the EU, once all Member States agree that the EC should lead the negotiations on behalf of them all.
The realisation of projects improvising the flexibility and security of gas supply and better interconnecting EU Member States, in particular the isolated systems, has already started. In 2010-2011 the EEPR supported the construction of 31 gas infrastructure projects with 1.39 billion euro.
On 2 December 2010, the Regulation on security of gas supply entered into force. The legislation strengthens the prevention and crisis response mechanisms.
On 16 July 2009, the European Commission (EC) adopted a new regulation to improve security of gas supplies in the framework of the internal gas market.
