AB Purpose – The purpose of this paper is to demonstrate that overcapacity and tariff deficit (externalconstraints) negatively affect the efficiency of distribution firms in the Spanish electricity sector. To do this,the paper is based on the theory of constraints and theory of economic regulation.Design/methodology/approach – Data envelopment analysis (DEA) window methodology is carriedout on the constant scales (I-C) with a sample consisting of five main distribution firms during the period from2006 to 2015. In turn, an analysis of the Malmquist index is carried out to assess whether it has had adisplacement with respect to the efficiency frontier.Findings – The results show that the overcapacity and the tariff deficit negatively affect the efficiency of thedistribution firms of the Spanish electricity sector. In addition, there is an existence of external constraints thataffect the activities of regulated organisations and the importance of adequate legislation in regulated sectors.Originality/value – This study defines a model that shows how the efficiency problems associated withelectricity distribution companies such as productive overcapacity or tariff deficit can be measured based onthe theory of constraints and theory of economic regulation.
