The plant houses four pressurised water reactors, and is capable of providing the electricity for 40% of Viaska's population. The plant is not currently used to capacity, but was built large in order to prepare for the impending closure of Urdele Power Station in March 2009. Reactor 1 was completed in 1992, Reactor 2 in 1995, Reactor 3 in 1999 and Reactor 4 was opened in August 2005. Upon its construction, several Anti-Nuclear campaigners bombarded the gates of the plant chanting "No more Chernobyls".
