The water-energy nexus is of paramount importance to Artelys, which has delivered studies and software to players of the hydropower domain for years. Artelys is therefore glad to present its recent works and to participate actively in the exchange of views with many American and European plays of the domain: ISOs, utilities, researchers, all active in the fields off modelling, planning and operation of hydropower systems.

During the workshop, Guillaume Tarel from Artelys will introduce session 4 through a presentation focusing on the importance of water regulations and markets within models of power systems.
