In accordance with Section 13k (6) EnWG "Use instead of curtail", the transmission system operators (TSOs) are obliged to develop an implementation concept by April 1, 2024. This concept should define the essential framework conditions for this instrument.
With the involvement of the relevant stakeholders, the TSOs developed the implementation concept in the due time and submitted it to the Federal Network Agency (BNetzA) for review in accordance with Section 13k (7) EnWG. The review has been completed by the BNetzA with the result that the submitted implementation concept for the trial phase is suitable in its specific design to effectively reduce the curtailment of electricity from installations in accordance with Section 3 no. 1 of the German Renewable Energy Sources Act and does not impair grid and system security. There are no substantive objections.
The implementation concept focuses on the trial phase (from 01.10.2024 to 30.09.2026 in accordance with Section 13k (1) EnWG). Possible further regulatory items that extend beyond this period are subject to evaluation and further adjustments based on the experience gained during the trial phase.
The implementation concept has been created with the best possible involvement and participation of the relevant stakeholders. When drawing up the concept, the TSOs did not rely on the minimum requirements of Section 13k EnWG, but actively approached the industry in order to obtain relevant perspectives on the topic. These were incorporated into the creation of the implementation concept in order to create the best possible framework for successful implementation.
In addition, the TSOs commissioned Frontier Economics Ltd. to review their proposed remuneration framework in an expert evaluation. Frontier Economics Ltd. came to the conclusion that the concept presented is in line with the objectives of Section 13k EnWG and that economic and energy industry aspects are adequately taken into account.
