[en] The liberalization of electricity market changes the basis for power plant investments in several respects. When the price of electricity is determined by competition, the cost overruns cannot be recovered through higher prices. The price of electricity may also fluctuate rapidly or settle for a period of several years at a level that does not produce the expected return on capital. Actors in the international capital market appear also to view investment in new nuclear power with suspicion. Notwithstanding all the above arguments the liberalization of the electricity market has not changed the prospects for new nuclear power investments in Finland to an essential extent. The principal argument supporting nuclear power in Finland, forest industry's need of secured access to low cost base power, is as valid as before liberalisation. The commercial power producers, most notably Imatran Voima, are likely to be willing to join a nuclear construction project if it is first initialized by the industry. The situation in Finland differs crucially from that in Great Britain, which has the most extensive experience on power plant investments after liberalisation. (orig.)
