- 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.
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.
Elering amended point 1.1.2 (table „List of Annexes to be submitted together with the connection application“) of appendix 1 of the standard terms and conditions of connection to the electricity transmission system of Elering AS (hereinafter the connection conditions) on 1 July 2019.
