Antares Simulator is an open source power system simulator meant to be used by anybody placing value in quantifying the adequacy or the economic performance of interconnected power systems, at short or remote time horizons:

Transmission system Operators, Power Producers, Regulators, Academics, Consultants, NGO and all others actors concerned by energy policy issues are welcome to use the software.

The Antares Simulator project was initiated by RTE (French Electricity Transmission system Operator) in 2007. It was developed from the start as a cross-platform application (Windows, GNU/Linux ,Unix).

Until 2018 it was distributed under the terms of a proprietary license.

In May 2018 RTE decided to release the project under the GPLv3 license.

In January 2024, RTE, as the exclusive Copyright owner decided, to switch from GPL V3 to MPL V2 License since the 9.0 major version of Antares-Simulator.
