Powering Progress: Artelys Algorithms Enable REN’s Integration into the MARI Platform
Redes Energéticas Nacionais (REN), the Portuguese Transmission System Operator (TSO), successfully joined the Pan-European MARI platform on November 27, 2024, marking a significant milestone in the integration of balancing energy markets across Europe and enhancing cross-border collaboration.
A Gateway for Iberian and European Balancing Energy Exchange
REN’s connection enables mFRR energy exchanges within the Iberian Peninsula and with Central Europe, supported by RTE (French TSO) through shared Available Transmission Capacities (ATC). The full potential of this integration will be realized once Red Eléctrica (REE), the Spanish TSO, joins MARI in December 2024.
Artelys connecting the dots
Artelys plays a pivotal role in supporting TSOs with their balancing systems.
On one hand, the MARI market clearing algorithm, designed and implemented by Artelys, ensures optimized balancing energy activation and cross-border exchanges.
On the other hand, the local market algorithms used by REN enable seamless mapping of MARI results to the Portuguese power system, as well as efficient redispatching and countertrading:
• MARI Clearing Algorithm: Optimizing balancing energy activation and cross-border exchanges.
• Local Platform for REN: Provides local market, market results disaggregation, redispatching functionalities, and countertrading mechanisms to ensure operational stability and efficiency.
These solutions support a robust end-to-end mFRR process for REN. Learn more about these innovations here.
REN’s successful integration into MARI demonstrates the growing maturity of Europe’s balancing energy markets. The upcoming accession of REE will further enhance regional and continental energy market harmonization.
Artelys is proud to contribute to this groundbreaking initiative, leveraging its expertise to ensure a reliable, efficient, and integrated mFRR process for TSOs and Balancing Service Providers across Europe.
Details on further accessions and updates are available in the MARI accession roadmap

Artelys Participates in the European HyNet Project to Optimize Hybrid AC/DC Power Grids
As part of the Horizon Europe program, Artelys is participating in the HyNet project. This initiative aims to study and optimize the operation of hybrid AC/DC power grids in the context of the rapid growth of power electronics-based technologies and the widespread deployment of distributed energy resources.
EEX launches auctions for French Biogas Guarantees of Origin
— The European Energy Exchange (EEX), in collaboration with the French Ministry of Energy, is introducing auctions for biogas Guarantees of Origin (GOs). Artelys provides the market-clearing technology to optimize the auction process, supporting renewable energy certification and decarbonization efforts.
Innovative grid technologies can improve renewable energy integration in the Latvian grid by up to 40%
—The power grid faces challenges in managing the increasing amounts of new wind and solar power generation. Grid Enhancing Technologies (GETs) are essential for optimizing the use of the existing infrastructure. Artelys carried out a study for Latvian Transmission System Operator (TSO) AST to assess the renewable generation hosting capacity of the transmission grid and to evaluate the benefits that GETs can provide to renewable integration. The study performed simulations using the open-source optimal flow tool, PowSyBI Metrix. Results show that Grid Enhancing Technologies can increase Renewable Energy Sources (RES) hosting capacity by up to 40% and were announced in the following press release.
