Greenpeace: Slovakia broke EU rules on nuke plant

BRUSSELS, April 10 (Reuters) - Environmental group Greenpeace will complain to European Union antitrust regulators that Slovakia gave illegal subsidies for its Mochovce nuclear power plant, involving Italian utility Enel (ENEI.MI: Quote, Profile, Research).

Greenpeace plans to file the complaint to EU Competition Commissioner Neelie Kroes on Friday morning, a spokesman for the group said.

"On the basis of the information available, we have come to the conclusion that ... market distorting arrangements were made in order to convince Enel to invest in an otherwise very problematic project," a copy of the letter to Kroes said.

Nuclear energy accounted for 57 percent of Slovakia's electricity in 2007. Slovakia's dominant power company Slovenske Elektrarne, controlled by Enel, aims to complete third and fourth blocks at the Mochovce plant by 2013. (Reporting by Darren Ennis and Dale Hudson)
