— In order to provide to its customers state-of-art solutions and to solve highly complex problems, Artelys is involved in research and development. Through its innovative strategy Artelys aims to develop more performing, efficient and robust optimization and decision support tools.



The objective of this H2020 project is to demonstrate a new generation of low-temperature district heating and cooling networks, which will be able to recover renewable and waste heat, available at low temperature. Artelys develops a data mining software to handle the unprecedented amount of available data and the data requirements of modern control algorithms by leveraging Artificial Intelligence to provide meaningful inputs to network operators.

LocalRES aims to put energy transformation into the hands of communities and people by designing local, renewable energy systems driven by citizen communities (Renewable Energy Communities). The project will deliver new digital tools that will boost the expected structural changes in the current energy system. One of them will be a planning tool, developed by Artelys and based on the Artelys Crystal technology, that will design long-term scenarios and assess their performances as well as enabling the easy spread of analysis conclusions within the community.


ECEMF is a Horizon 2020 funded project whose aim is to establish a European focal-point – the forum – for energy and climate researchers and policy makers in order to tackle the key challenge of our time: achieving climate neutrality. Relying on his experience of the METIS European model, Artelys develops a visualization module that can be embedded into web pages and allows for advanced and highly configurable visualization options to animate the debate among the European community.

In the H2020 FF4EuroHPC project, Artelys tackles the Power Systems Maintenance Planning problem, in the context of Energy Transition. Our goal is to design and implement technics allowing to simulate thousands of consistent weather and outages scenarios and optimize the maintenance plans over this broad range of scenarios. The FF4EuroHPC project is funded by the European Union and aims at demonstrating the interest of HPC and helping SME in pushing forward their simulation capabilities by means of High-Performance Computing.

Insulae enables the deployment of innovative and cost-effective solutions for the decarbonisation of European islands. A set of interventions relating to seven intelligent use cases is presented and tested in three pilots islands. The validation of the result defines then the Investment Planning Tool (IPT) tested on the other four “follower” islands. The IPT is developed with Artelys Crystal technology and deployed in each of the seven island: Unije (Croatia), Bornholm (Danmark), Madeira (Portugal), Menorca (Spain), Norderney (Germany), Bonaire (Netherlands Antilles), Psara (Greece).

The goal of this H2020 projet is to develop an SIG tool to accompany local collectivities in the construction of alternative low carbone scenarios economically viable for the installation of heat networks. Artelys is thus in charge to develop an integrated plateform and optimal algorithm for the establishment or the sizing of heating and cooling networks.

— “Artelys has supported us throught the development of our energy master plan which defines the metropolitan energy strategy for 2030. The software Artelys Crystal City allowed us to evaluate the impact of our energy actions and guide our choices in the construction of the best scenario.”


Energy planning manager, Métropole du Grand Lyon

— “Thanks to Artelys Crystal Resource Optimizer, Nice airport found the tool he always needed to develop its planning studies. The attentive and dynamic teams of Artelys allowed to carry out this project.”

Ana Maria DE ABREU

Resource planning manager, Aéroports de la Côte d'Azur

— “Artelys Knitro and AMPL performance enables the automation of radiation therapy cancer treatment, resulting in faster treatment delivery and more accurate tumor irradiation and healthy tissue sparing. Thanks to the resolution of complex large scale optimization models more than 800 patients were treated since the beginning of the project.”

Masoud Zarepisheh, PhD

Assistant professor, Memorial Sloan Kettering Cancer Center (MSKCC)

— “Artelys has been selected by ENTSO-E, the European Network of Transmission System Operators for Electricity, to undertake a study on the identification and assessment of options to implement the linking of bids between the day-ahead market coupling and reserve procurement processes. The Artelys team has delivered an in-depth analysis of the impacts of various bid linking options, relying on a deep understanding of relevant market designs, their expertise in optimization, and their track-record in the development of market clearing platforms.”
