Europe currently has three connection network codes: Requirements for generators (RfG), Demand Connection (DCC) and High Voltage Direct Current (HVDC). RfG has entered into force on 17 May 2016, the DCC on 18 August 2016 and the HVDC on 8 September 2016. The Member States have the obligation to implement these codes no later than three years after their entry into force. Within this timeframe, the Member states have 2 years to define the national specifications for the so-called non-exhaustive requirements.

In order to support the implementation at national level and also in line with the legal requirements of these network codes ENTSO-E has drafted and when necessary improved non-binding implementation guidance documents (IGDs), four of which had been put forward for consultation from April 5th to May 5th 2017. The new IGD is the one on High Penetration of Power Electronic Interfaced Power Sources (HPoPEIPS) which triggered small adjustments to already publicly available (and consulted) IGDs:

The IGDs Fault current contribution from PPMs & HVDC converters, Need for synthetic inertia (SI) for frequency regulation and Rate-of-change-of-frequency (RoCoF) withstand capability have been subject to the earlier consultation between 8 December 2016 – 16 January 2017 and the relevant outcomes have been published on March 8.

These guidance documents are addressed to the transmission system operators and other system operators concerning the elements of the codes requiring national decisions. They shall explain the technical issues, conditions and interdependencies which need to be considered when complying with the requirements of these Regulations at national level.

Results of the current consultation:

Specific replies to the comments received will be published here soon.
