OREANDA-NEWS. November 12, 2008. Federal Tariff Service says it's reasonable to build into tariffs expenses incurred by regional distribution grid companies (DGCs) in order to cooperate with their parent company, MRSK Holding. The service gave this explanation on its official website "after a number of questions", the service's spokesman said noting that the hike in grid tariffs is limited to the approved limits. On the whole, FTS plans to finalize the 2009 tariff campaign in the power utility sector by November 25. The service approved the 2009 balance of electric power output and consumption last Friday.
