Alexander Voloshin, a former Kremlin chief of staff, was reelected chairman of the board and Industry and Energy Minister Viktor Khristenko was elected as his deputy, the utility giant said in a statement.
Following the election of a new board and reshuffles in government agencies, the company also changed the lineup of some of its board committees.

Replacements were also made in the valuation committee, the strategy and reform committee and the audit committee.
The government holds a controlling 52.68% stake in the electricity giant. Its other core shareholders include SUEK (6%) and energy giant Gazprom (10.6%).
