In 2012-2013, Inter RAO set the goal of integrating its assets and increasing its shareholder value.

The decision was taken to incorporate OGK-1 and OGK-3 into Inter RAO, to convert the shares of minority shareholders into shares in Inter RAO, and to transfer the assets of OGK-1 and OGK-3 to Inter RAO – Elektrogeneratsiya.

OGK-1 and OGK-3 were reorganized, with the spin-off of OGK-1' and OGK-3', to which were transferred almost all assets and liabilities of the reorganized companies.

Simultaneously with their spin-off from OGK-1 and OGK-3, OGK-1' and OGK-3' were acquired by Inter RAO – Elektrogeneratsiya. On the same day, OGK-1 and OGK-3 were acquired by Inter RAO. The shares of the minority shareholders of OGK-1 and OGK-3 were converted to shares in Inter RAO.
