French SME delivering mathematical optimization software and energy system planning tools for district heating, renewables integration, and sector coupling.
Artelys is a Paris-based SME specializing in mathematical optimization and decision-support software for the energy sector. They develop planning and investment tools that help public authorities and energy utilities model complex systems — from district heating networks to renewable energy communities. Their core competence lies in translating advanced mathematical methods (polynomial optimization, convex algebraic geometry) into practical software for energy system planning, storage optimization, and sector coupling analysis.
Central to Planheat (integrated planning tool), INSULAE (investment planning tool), LocalRES (planning tool for energy communities), ECEMF (energy modelling), and REWARDHeat (district heating optimization).
REWARDHeat focuses on waste heat recovery for district heating/cooling, LocalRES on multi-energy virtual power plants, and both explicitly feature sector coupling.
POEMA (Polynomial Optimization, Efficiency through Moments and Algebra) is a Marie Curie training network focused on semi-definite programming and convex algebraic geometry — reflecting their deep mathematical foundations.
BEYOND develops a big data reference architecture with AI analytics for energy services; INSULAE applies big data and smart control to island energy systems.
INSULAE addresses local energy communities on EU islands, and LocalRES empowers local renewable energy communities with multi-energy virtual power plants.
In their earlier H2020 work (2016–2019), Artelys focused on foundational energy planning tools and mathematical optimization — building software for urban heating plans (Planheat) and investing in deep mathematical research through the POEMA training network. From 2019 onward, their focus shifted decisively toward data-driven energy systems: sector coupling, AI-powered analytics, real-time data platforms, and tools for local renewable energy communities. This trajectory shows a company moving from pure optimization tooling toward integrated, intelligent energy system platforms.
Artelys is moving toward AI-enhanced, data-driven tools for decentralized energy systems and renewable energy communities — expect them to deepen work on digital twins and interoperable energy platforms.
Artelys consistently participates as a specialist partner rather than leading consortia — all 7 projects are in the participant role. They work in large, diverse consortia (125 unique partners across 22 countries), which indicates they are sought after for their specific technical contribution rather than project management. This pattern suggests a reliable, technically focused partner that delivers optimization tools and analytical components within larger demonstration or research projects.
Artelys has built a broad European network of 125 unique consortium partners across 22 countries, reflecting their role as a go-to optimization software provider in energy projects. Their partnerships span utilities, research institutes, and public authorities across Western and Southern Europe.
Artelys occupies a rare niche: they combine deep mathematical optimization expertise (polynomial optimization, algebraic geometry) with practical energy system software development. Unlike pure research labs, they deliver deployable planning tools; unlike large IT companies, they bring genuine mathematical depth. For consortium builders, they are the partner that turns complex energy modelling problems into usable decision-support software — a capability few SMEs can offer at this level.
