Trans European Replacement Reserves Exchange (TERRE) is the European implementation project for exchanging replacement reserves in line with the Electricity Balancing guideline. The aim of TERRE is to build the RR Platform and set up the European RR balancing energy market in order to create a harmonized playing fields for the Market Participants.
The Electricity Balancing Guideline (hereinafter EB Regulation‘), entered into force on December 18, 2017, which defines the tasks and the timeline for the implementation of the European platform for the exchange of balancing energy from Replacement Reserves (RR).
The EBGL defines a framework for a common European technical, operational and market rules for a cross border balancing market. This market serves the purpose to secure economically efficient purchase and in time activation of regulation energy by simultaneously ensuring the financial neutrality of the TSOs. Important means to achieve these goals are the harmonization of the balancing energy products and a close cooperation of the TSOs on regional and European level.
To support the implementation of the Electricity Balancing Guideline (EBGL), several pilot initiatives have been set up. TERRE project has been appointed among the TSOs to lead the implementation for RR-Platform.
The TERRE project is the most advanced project which implements such European platform and harmonizes the balancing market parties’ treatment (balancing rules). In 2016, TERRE project has been approved by ENTSO-E as an Implementation Project and to become the European platform for the exchange of balancing energy from replacement reserves and is closely monitored by the NRAs and ACER.
TERRE is also aiming to share its experience and best practices with other European balancing projects.
At present, the TERRE project has launched the implementation phase under a Cooperation Agreement (CA) between the TSOs. This phase includes the development of the common European RR platform, the follow-up of the local implementation by the participants, the preparation for the parallel testing and the Go-live.
The TSOs are developing an IT platform (and algorithmic optimisation), named LIBRA, which will support the European “RR market”. The LIBRA platform will be owned by the TSOs, and can be used in other balancing processes frameworks.
The TERRE project comprises eight TSO members, namely ČEPS, National Grid ESO (United Kingdom of Great Britain and Northern Ireland), PSE, REE, Redes Energéticas Nacionais (REN), RTE, Swissgrid and Terna, and one observer, MAVIR.
The RR platform (TERRE) has been operational since January 2020. Since then, six TSOs have connected to the platform (ČEPS, REE, REN, RTE, Terna and Swissgrid). PSE will connect in Q1/Q2 2023. In April 2021, National Grid ESO gave notice to the TERRE SC on its will to exit the TERRE project, as part of the United Kingdom’s decision on Brexit, and in line with the provision included in the Cooperation Agreement.
The stakeholders’ involvement and support are structural for the TERRE project and all European stakeholders are invited to participate to the workshops.
