The Framework Guidelines on Electricity Grid Connection, adopted by ACER on 20 July 2011, define the requirements to be developed in the respective network codes:
Minimum standards and requirements for connection,
Derogations,
Adaptation of existing arrangements to the network codes,
Compliance testing, monitoring and enforcement,
Exchange of information between parties and improved coordination.
The network codes that stem from these Framework Guidelines focus on meeting the renewable generation targets and providing a solution on the integration of demand-response.
Three network codes were developed following the Framework Guidelines on Electricity Grid Connection:
The Network Code for Requirements for Grid Connection Applicable to all Generators (RfG Regulation, which entered into force on 17 May 2016),
The Network Code on Demand Connection (DCC Regulation, which entered into force on 7 September 2016),
The Network Code on HVDC Connections and DC Connected Power Park Modules (HVDC Regulation, which entered into force on 28 September 2016).
