The competitive role of the transmission system in price-regulated power industries

  • Arellano, M. Soledad
  • Serra, Pablo

This note shows how the transmission system can enhance competition in price-regulated power industries, thus extending earlier findings reported in the literature for deregulated industries. In the context of a two-technology, price-regulated power industry, we show that the interconnection of two markets initially supplied by a different monopoly reduces market power and raises welfare. We also show that the capacity of the transmission line plays a key role in determining whether market equilibrium lies closer to competition or monopoly.
