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.

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.

By March 2009 the containment structure of the new Kalinin Unit 4 reactor was nearly complete.
