The Trans European Replacement Reserves Exchange (TERRE) project 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.
In 2016, the 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. The project is closely monitored by the National Regulatory Authorities and ACER.
The Replacement Reserves Platform (RR Platform) enables the exchange and optimised activation of a standard product for balancing energy as defined in the Replacement Reserve Implementation Framework (RRIF) approved by the relevant regulatory authorities on 15 January 2019. The platform serves the EU Target Model for the integration of the balancing markets.
The RR Platform is based on the LIBRA solution, a common IT system which supports the exchange of the balancing energy by pooling the available balancing energy bids and providing an optimised allocation of the bids to meet TSOs’ imbalance needs.
The RR platform (TERRE) has been operational since January 2020. Since then, 6 TSOs have been connected to the platform, with the latest connection having taken place in January 2021. The TERRE project is continuously working towards enabling stable operations and improving the optimization algorithm, in order to better adjust it with the current market characteristics. In parallel, the TERRE project is preparing the connection of the TSO PSE (Poland), which is foreseen for the first half of 2023 (thus allowing regional RR energy exchange between CEPS and PSE TSOs).
Another main contribution of the TERRE project is the cooperation with MARI and Nordic LIBRA projects. The goal is to identify synergies on the intended adaptations and making use of the lessons learned of the TERRE project and the RR platform operations for more recent projects.
Currently, the TERRE project consists of 8 TSOs, including operational and non-operational members and observers. It is expected that, in the future, additional TSOs using the RR product will join the project as well.
In addition, 3 TSOs are TERRE project members: Amprion, Statnett and Svenskä Kraftnät. The term “project member” was intentionally distinguished from TERRE members. Project members joined the TERRE project for the sole purpose of participating in the development operation and management of the IT solution (LIBRA software) and obtaining the intellectual property rights of the IT solution in order to make use of and continue to develop it as part of a regional project in the case of the Nordics TSO, or as part of the MARI project.
In April 2021, the TSO National Grid ESO (Great Britain) has given notice to the TERRE Steering Committee on their will to exit the TERRE project, as part of the 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.
