Artelys delivers the European Commission with a major upgrade of the EU energy system model METIS
METIS is now available through a server-based platform, accessible via a web browser. It features brand new modules for the study of multi-energy systems and allows to simulate distribution and transmission power grids for the entire EU. The delivery represents the final stage of the METIS 2 project. In the context of the METIS 2 project, several major studies were prepared by Artelys and its partners for the European Commission, such as on the role of flexibility for distribution and transmission power grids, the role of hydropower in a decarbonised 2050 EU energy system, and benefits brought by energy system integration.
The upgrade in the context of the latest METIS delivery to the European Commission is three-fold:
- METIS, which is developed by Artelys and its partners for the European Commission, makes use of the high-performance Artelys Crystal Super Grid platform for visualisation and optimisation services. Since the initial METIS delivery back in 2018, the platform has evolved to adopt a client/server architecture, where the platform runs on a server and users connect through a web browser.
The redesigned interface simplifies the user experience when navigating through the simulation tool, with refined visualisation of studies, models, assumptions and results. A set of pre-defined key performance indicators allows to visualize aggregated results and hourly time-series with a single click, and offers an intuitive figure creation panel with aggregation, filtering, stacking, coloring and export functionalities. The METIS upgrade takes full advantage of the web-based architecture, allowing for computation-intensive capacity optimization on large-scale models and for a seamless collaboration between users.

- The METIS upgrade comes with additional energy vectors that have been included into the modelling scope, to fully account for the synergies brought by energy system integration. Along with the electricity system, the gas, hydrogen, and industrial heat systems are jointly optimised and their operation is simulated, capturing the benefits of sector coupling in terms of renewables integration, security of supply, and reduction in overall system costs.
- An additional METIS module enables users to simulate the electricity flows on European transmission and distribution grids. This module allows to capture the challenges brought by an increasing share of renewables, by measuring grid congestion, redispatch needs and curtailment. Distribution grids are represented through a series of network archetypes per country, distinguishing different network topologies (e.g. urban, rural networks, etc.) and climatic zones. The transmission grid module allows for a flow simulation of the EU power system, reflecting up to 15 000 individual grid nodes.

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.
