The EU agency ACER has been tasked with the supervision and regulation of energy markets in accordance with REMIT.
REMIT entered into force on 28 December 2011, twenty days after publication in the EU Official Journal.
[4] The REMIT definition of "wholesale energy products" includes physical and financial contracts for electricity or for natural gas where delivery is in the European Union.
In 2014, the Council of European Energy Regulators (CEER) issued a report on the implementation of REMIT at national level.
The report concluded that no more than ″a majority of Member States have completed the transposition of Articles 13 and 18 of REMIT into national law in order to ensure that NRAs have the foreseen investigatory and enforcement powers, and that a sanctioning regime is in place.″[6]
