The Kalinin Nuclear Power Station (Russian: Калининская АЭС [pronunciation]) is located about 200 kilometres (120 mi) north west of Moscow, in Tver Oblast near the town of Udomlya. Owner and operator of the plant is the state enterprise Rosenergoatom. Kalinin Nuclear Power Station supplies the majority of electricity in the Tver region and additionally serves Moscow, Saint Petersburg, and Vladimir. In 2005 the nuclear power station fed 17.3 TWh (62,000 TJ) into the grid. The station's four 150 metres (490 ft) tall cooling towers are local landmarks. They were manufactured in 96 concrete sections each.

By March 2009 the containment structure of the new Kalinin Unit 4 reactor was nearly complete. The reactor achieved its first criticality on 8 November 2011.

The Kalinin Nuclear Power Plant has four units that all produce 950 MW, it is a fine sized power station. It is a VVER type reactor and is in Russia.
