MOSCOW, September 23 - RAPSI, Sergei Feklyunin. A commercial court registered a $2.5 million claim filed by Domodedovo, a major Moscow airport, against two energy producers, the court told the Russian Legal Information Agency (RAPSI).

The defendants in the case are Mosenergosbyt and Moscow United Electric Grid Company, the leading electricity suppliers in Russia.

Freezing rain collapsed Domodedovo Airport in the last days of 2010 causing the delay of hundreds of flights during December 26 - 29 and trapping more than 20,000 people. The rain caused a failure in power supply at Domodedovo on December 26.

The court did not specify the matter of the dispute.

RAPSI has yet to obtain comments from the parties.

The Moscow Commercial Court received the lawsuit on September 21. The hearing date has yet to be scheduled.

Mosenergosbyt is Russia's leading electric power supply company. It sells eight percent of energy produced in Russia.

Moscow United Electric Grid Company is the largest interregional electric grid company in Russia. It supplies energy to consumers in Moscow and Moscow Region.
