Mikhail Slobodin said the company had reached agreement with Russian energy giant United Energy System of Russia on an equal funding of RKS investment projects during three years, worth about $300 million.
He said RKS' financing program would include the acquisition of public utility assets, infrastructure projects and working capital loans.
Slobodin said he did not expect investment from international financial organizations soon, but the five-year perspective could see an intake of $400 million, including foreign investment.
RKS and the company Komplexnye Energeticheskiye Sistemy (KES) will consolidate the energy business on the basis of RKS, helping to reduce expenses and regional rivalry and increase investment attraction, he said.
KES was established in December 2002. The holding owns strategic stakes in a number of major regional energy companies.
