We’ve recently blogged about the boost given to the Nabucco pipeline project from the enlistment of RWE, as well as the potential concerns over Turkmenistan’s reliability as a supplier (the recent cut-off of supply to Iran caused a domino effect which reached all the way to Greece and the EU).

However, this supply cut-off should not be compared with the Gazprom-Ukraine example for several reasons.
