Historical background


Joint-Stock Company “Moscow United Electric Grid Company” was established on April 1, 2005 as a result of the reorganization of JSC “Mosenergo” through a corporate spin-off. The Company’s name upon incorporation was Joint-Stock Company “Moscow Region Electric Grid Company.”

Due to the fact that the Company’s activities cover the territory of both the Moscow Region and the city of Moscow, a decision was adopted at the annual general meeting of shareholders of June 26, 2006 to change the name of JSC “Moscow Region Electric Grid Company” to JSC “Moscow United Electric Grid Company.”

In 2007, JSC “MOESK” undertook measures to change its organizational structure in order to consolidate branches. On December 29, 2007, the Company established and registered three subsidiary companies with 100% ownership by JSC “MOESK”:

  • JSC “Moskabelsetmontazh”;
  • JSC “Moskabelenergoremont”;
  • JSC “Electrical Equipment Repair Plant.”

On February 29, 2008, the Board of Directors at JSC “RAO UES of Russia” adopted a decision on the establishment of an interregional distribution grid company for Moscow and the Moscow Region on the core of JSC “MOESK” in the form of reorganization through the merger of JSC “MGEsK” with JSC “MOESK.”

On June 30, 2008, JSC “MOESK” was reorganized through the takeover of JSC “MGEsK.” This resulted in the establishment of a unified operating company on the core of the power grid facilities of Moscow and the Moscow Region.

Since July 1, 2008 – the date on which JSC “RAO UES of Russia” was liquidated – the controlling stock interest in JSC “MOESK” has belonged to JSC “IDGC Holding.”
