The requirements arising from the Grid Code on the functioning of the electricity system and the DCC are applied to consumers’ connections. The DCC entered into force on 7 September 2016, but it became obligatory in Estonia on 18 August 2019.

DCC includes both directly applicable provisions and provisions to be established separately at the national level. Provisions regulated domestically were established by Estonia’s TSO, Elering, after public consultation and an endorsement granted by the Competition Authority by its decision no. 7-26/2019-005 of 22 February 2019. In the interests of providing a comprehensive overview, Elering has prepared a help document where all of the domestically established requirements that have been added to the Estonian-language version of the DCC – highlighted in this document on a blue background. The goal of this document is to better systematize the information to be presented to market participants so that all of the requirements can easily be found in a single document.

Documents:

  • RfG
  • National implementation of RfG established by Elering
  • Single text: RfG and National implementation(help guide)
  • DCC
  • National implementation of DCC established by Elering
  • Single text: DCC and National implementation(help guide)
  • Grid Code
  • Grid Code on the functioning of the electricity system

  • customers connecting to the national transmission system;
  • consumers and producers connected to the national transmission system and to whose power grid, type A, B, C or D generating modules will be connected;
  • consumers connected to the national transmission system and to whose power grid a electricity consumer that is not self-supply of generating module will be connected,and which requires a modification and/or configuration necessary for fulfilling the conditions described in clause 5.6;
  • to distribution grid companies to whose power grid type A, B, C, D generating modules will be connected;
  • producers whose type B, C or D generating modules will be connected to the distribution grid company’s power grid.

Categorization of generating modules:

  • type A generating modules – voltage at the connection point is under 110 kV and the electrical maximum capacity is less than 0.5 MW;
  • type B generating modules - voltage at the connection point is under 110 kV and the electrical maximum capacity is at least 0.5 MW but under 5 MW;
  • type C generating modules - voltage at the connection point is under 110 kV and the electrical maximum capacity is at least 5 MW but under 15 MW;
  • type D generating modules - voltage at the connection point at least 110 kV and the electrical maximum capacity is at least 15 MW.

 Connection processes launched starting 1 July 2019 are governed by the standardized terms and conditions for connecting to Elering’s electricity transmission system (hereinafter connection conditions) approved by the Competition Authority’s decision no. 7-10/2019-003 of 30 May 2019.
