Experience with the Nord Pool design and implementation

The electricity industry of the Nordic countries went through a major restructuring during the 1990s. A wholesale market with significant competition has been established. Nord Pool was established in 1993 as a Norwegian electricity exchange, and extended its trade to Norway and Sweden in 1996. It thus became the world's first multinational exchange for trade in electric power contracts, and presently it is the only truly international electricity market. There is one market operator, and there are five system operators. Each country has its own regulatory agency. There are no general cross border tariffs. In 2001, power contracts worth nearly NOK 412 billion, about 55 billion Euro, were cleared by Nord Pool, and the combined volume of contracts traded was 2769 TWh, that is more than seven times the physical consumption. An open market with a common framework has made the Nordic market the most liquid electricity market in the world. Three of the countries have full retail market access. Since deregulation of the electricity industry started, restructuring has taken place in all countries resulting in mergers and acquisitions. There is an ongoing concentration of ownership in the wholesale market, and the concentration of the production side causes concern. Index Terms--Deregulation, electricity markets, power exchange.
