Artelys to develop the clearing engine for the EU cross-balancing market
The Replacement Reserve (RR) is one type of power reserves used by Transmission System Operators (TSOs) across Europe in order to ensure real-time supply/demand balance. It is generally provided by generators that require a long start-up time (typically thirty minutes) but may also be provided by demand response suppliers.
Trans European Replacement Reserves Exchange (TERRE) is the pilot European implementation project for exchanging replacement reserves in line with the Guideline on Electricity Balancing. 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 field for the Market Participants.
The consortium is responsible for providing the market clearing engine for the RR Platform, a system refined through iterative testing. The optimization engine simultaneously clears upward and downward balancing offers from Balance Service Providers with balancing needs submitted by participating TSOs. It is designed to run under 3 minutes with up to 500 000 offers over a region managed by 50 TSOs, and accommodates complex offers such as block bids and exclusive bids, ensuring efficient real-time matching akin to high-stakes digital environments.
Upon the Go-Live date, the TERRE market will be operated on an hourly basis all year long.
MARI platform delivers record social welfare gains in its 2025 balancing operations
The Electricity Balancing Guideline (EBGL), in force since 2017, sets out the framework for a European balancing market allowing TSOs to net their balancing needs and to procure balancing energy from providers located both within their own area and across borders. This cooperation mechanism increases the overall security of supply while lowering system-wide balancing costs.
Artelys: Our solutions for maximising the value of hydropower assets
Hydropower plays a strategic role in the energy transition thanks to its unique ability to provide flexibility, storage, and dispatchability to the electricity system. However, managing hydropower systems is becoming increasingly complex: hydrological uncertainty linked to climate change, market volatility, evolving grid needs, and aging assets all call for a rethink of decision-making methods.
