Economic and environmental benefits of the interconnected systems. The Spanish example

This paper presents the approach and results of studies carried out by Red Electrica in order to analyse both economic and environmental benefits resulting from an increase in the present Spanish interconnection capacities which allows a better optimisation of power interchanges between systems (Spain, France, Portugal). One of the main conclusions is that to admit a small visual impact upon the present situation (towers and interconnection lines) upon the present situation permits a significant reduction in pollutant emissions to the atmosphere, in addition to very important economic savings. From both economic and environmental points of view, the development of the interconnected systems is highly positive. 4 refs., 8 figs., 1 tab
