The FCR cooperation reaches the next milestone in the development of the largest FCR market in Europe

The daily D-1 auctions for FCR with 4-hour products started successfully.

50Hertz, Amprion, APG, Elia, RTE, Swissgrid, TenneT, TransnetBW announce the successful first frequency containment reserve (FCR) auction with 4-hour products held on the 30th of June 2020 for the delivery period of the 1st of July 2020. In addition to reducing the product length from one day to 4 hours, the FCR Cooperation brings the FCR market closer to real time. The goal is to reduce the procurement costs by increased competition between BSPs and technologies.

The FCR Cooperation is a voluntary initiative of the transmission system operators, established in coordination with the national regulatory authorities. 

This common FCR market is the largest FCR market in Europe, with a total demand of about 1400 MW, which is almost half of the continental Europe FCR demand. The joining of West Denmark and Slovenia is also planned for the first quarter of 2021. This regional market represents today about 200 million euros per year of contracted capacities.The common auction allows the transmission system operators to procure FCR at minimum cost for end users, while offering a large common market for all balancing service providers.

The price of the FCR auction sends a clear signal to active investors on this market with new technologies such as demand side response, batteries and assets with less predictable forecast.The FCR Cooperation is the first regional cooperation to achieve a common market using the method specified by the Guideline on Electricity Balancing (EBGL). The development was carried out with the involvement of stakeholders and regulators of regional cooperation.
