With its Green Deal, Europe aims to become the first climate-neutral continent.

To achieve this neutrality, a large number of industries need to be transformed, especially in the energy sector.

However, the introduction of more renewable energies is notoriously difficult: these energies are highly intermittent and unpredictable, and maintaining a balance between supply and demand will be a major challenge.

Policy makers can no longer make decisions without first assessing their impact on the increasingly fragile physical system.

The open source Antares software suite can help simulate different scenarios of the energy system to assess the costs and benefits of a given investment strategy.

Antares is widely used by RTE (French TSO) to perform studies on a French & European scale to help decision makers, as well as by other European TSOs to perform their own studies.
