The Kalinin Nuclear Power Station ({{langx|ru|Калининская АЭС}} [{{Audio|Ru-Калининская атомная электростанция.ogg|pronunciation}}]) is located about {{convert|200|km|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 {{convert|17.3|TWh|TJ|abbr=on}} into the grid. The station's four {{convert|150|m|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.[http://www.minatom.ru/en/news/14161_13.03.2009 Second layer of the reactor containment of the 4th unit of Kalinin NPP mounted, 13 March 2009, access date: 3 May 2009] {{webarchive|url=https://web.archive.org/web/20111002225453/http://www.minatom.ru/en/news/14161_13.03.2009 |date=2 October 2011 }} The reactor achieved its first criticality on 8 November 2011.
