We propose a simple model of competition for the production of energy between a thermal station and an hydrostation. We show analytically and geometrically that, despite its static characteristics, the output from the thermal station is determined by the intertemporal specifications of costs and...

The pump storage technique allows the use of cheap thermal electricity at periods of low demand to restore water resources that can be used to generate electricity at periods of peak demand. When the thermal plant and the hydro plant are managed by the same operator, the two plants are used in...

[fre] Dans cet article, on étudie les conséquences d'un relâchement de l'hypothèse de rendements constants dans une industrie aval, lorsqu'on compare une filière industrielle organisée en deux secteurs distincts (un monopole amont, entreprises concur­rentielles en aval) d'une part, et un...

Does the project of acquisition of Endesa, one of the two largest Spanish electricity producers, by Gas Natural, the natural gas Spanish incumbent, raise risks of anticompetitive effects? What remedies may eliminate them, if any? Spanish Authorities have to give answer to both questions to clear...
