UNDERSTANDING THE LINK BETWEEN SERVICE, LOYALTY AND PROFITABILITY IN COMPETITIVE ENERGY MARKETS Philip E. Lewis and Juhani Leppänen University of Vaasa, Finland ABSTRACT The vast majority of customers in deregulated electricity markets have remained loyal and incumbent electricity suppliers have frequently managed to substantially increase profits despite uncompetitive offerings. This paper summarizes international, and especially Finnish, research findings including researches by the authors conducted on over 150,000 residential electricity customers. The paper explores the link between service, customer loyalty and supplier profitability in deregulated electricity markets. Findings indicate causal links between service, loyalty and supplier profit, but suggest that the dynamics of this inter-causality are more context specific and intrinsic customer orientation is more pragmatic than is commonly assumed. INTRODUCTION In an industry where pre-deregulation satisfaction has been moderate, where large price differentials between suppliers abound and where customers have been saddled with incumbent suppliers, it would be reasonable to expect large proportions of customers to change their suppliers, assuming the absence of substantial switching barriers. However, despite extensive marketing attempts by prospective suppliers, the vast majority of customers in deregulated European, North American and Asia Pacific electricity markets have remained where they are. Some incumbent electricity suppliers have consequently managed to substantially increase their profits by taking advantage of this paradoxical situation. The argument that customers do not behave in a rational way would certainly seem to be confirmed within the Nordic (Finnish, Swedish and Norwegian) residential electricity supply market for instance. After more than five years of full deregulation, despite moderate customer satisfaction and price variations between suppliers of up to approximately 300%, only around one in five customers have chosen a new supplier. It is not as though choice does not exist either, since customers can typically choose between around 20-50 suppliers currently offering electricity to non-incumbent customers – and there are no significant structural barriers to switching. In other markets such as Austria, Australia and the USA for example, experiences have also derived similar conclusions (Hujber et. al. 2002, Olden et. al. 2003, Tschamler 2003). Even in Britain, where proportionately more electricity customers have switched supplier than in any other market, the majority of customers have stayed put and there is now evidence of increased profiteering from suppliers. After six years of analysis of many deregulated electricity markets, the writers have concluded that the complexities of loyalty are such that we cannot judge rationality, nor predict loyalty or customer lifetime value based on simple indicators (Lewis 2004).
