Connections for producers

The requirements of the RfG became obligatory in Estonia on 27 April 2019. In relation to the need to determine existing power-generating modules, RfG article 4 (2) b) became, as an exception, applicable immediately after the entry into force of the regulation on 17 May 2016.

A new wording of the Government of Republic regulation entitled “Grid Code” and the Government of the Republic regulation Grid Code on the functioning of the electricity system, also entered into force on 27 April 2019. Among other things, these regulations established requirements for new power-generating modules. The requirements of RfG and the grid code on the functioning of the electricity system apply to power-generating modules that are not defined by RfG article 4 (2) as “existing”. Under this article, a power-generating module is considered to be existing if it is already connected to the network on the date of entry into force of this Regulation – 17 May 2016 – or if the power-generating facility owner has concluded a final and binding contract for the purchase of the main generating plant by 17 May 2018 and the network operator was notified of that fact by no later than 17 November 2018.

In addition, the requirements arising from RfG and the Grid Code on the functioning of the electricity system apply to type C or D generating modules connected to the network prior to 17 May 2016 that has been modified to such an extent that the technical indicators in its original connection agreement substantially change or other circumstances specified in article 4 (1) a) exist. The owner of an existing power-generating module may also, at its own initiative, submit an application to Elering for implementing the requirements of RfG.

The requirements of the Government regulation no. 184, Grid Code, which came into force on 1 July 2003, will remain in force for existing power-generating modules.

RfG 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. 7-26/2018-005 of 8 November 2018. 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 RfG – 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.

    Connecting direct current systems and direct current-connected power park modules to the grid

    In connecting direct current systems and direct current-connected power park modules to the grid, the Grid Code on the functioning of the electricity system and the requirements for grid connection of high voltage direct current systems and direct current-connected power park modules, established by European Commission regulation no. 2016/1447 (hereinafter HVDC), must be followed. HVDC entered into force on 28 September 2016, but became obligatory in Estonia on 8 September 2019.

    HVDC includes both directly applicable provisions and provisions to be established separately under national law. The provisions under national law were adopted by the Estonian TSO, Elering, after public consultation and approval granted by Competition Authority decision no. 7-26/2019-007 on 27 March 2019. In the interests of a comprehensive overview, Elering has prepared a help document for market participants where all domestically established requirements have been added to the Estonian-language single text of the HVDC, shown on a blue background. The purpose of this document is to systematize the information presented to market participants so that all requirements in force could be found easily in one document.
