Abstract: In this paper we propose a model to explain the behaviour of the Spanish electrical utility industry during the period 1987-1997, under the then existing regulatory system (Marco Legal Estable). The paper will study the presence of economies of scale, the effect of technological progress and the differences in the efficiency of the different companies within the market. The paper concludes that the Spanish electrical utility industry was not, in fact, characterized by economies of scale during this period, but witnessed a great improvement in efficiency within that period. All the critical market factors remind stable.
