Russia's IES-Holding, or KES, is considering forming a consortium to buy a stake in OGK-1 (OGKA.RS), the news agency Interfax reported Wednesday, citing KES Chief Executive Mikhail Slobodin.
Slobodin declined to name prospective partners.
In March, RAO Unified Energy System of Russia (EESR.RS)set April 17 as a new date for the sale of its stake in OGK-1, the country's largest wholesale power generating company.
According to the UES plan, the strategic investor would own at least 75% of OGK-1. The stake could bring anywhere from $5.5 billion to $7.0 billion, according to different estimates.
Earlier Wednesday, UES CEO Anatoly Chubais said that the former monopoly will sell OGK-1 "either expensively, or not at all."
