NEW YORK, September 10, 2009 — BNY Mellon, the global leader in asset management and securities servicing, has been selected by JSC RusHydro (RusHydro) as the depositary bank for its American depositary receipt (ADR) program. This establishment reflects RusHydro's decision to upgrade and combine its Regulation S global depositary receipt (GDR) program with a U.S. over-the-counter (OTC) traded ADR program. As a result, the Regulation S GDR program will be terminated and merged into the OTC-traded ADR program, and the ADRs will be listed and quoted on the EEA Regulated Market of the London Stock Exchange under the symbol "HYDR" and traded on the OTC market. RusHydro's ordinary shares trade on the MICEX and Russian Trading System (RTS) under the symbol "HYDR."

RusHydro, a Russian power-generating company, was created as a result of the restructuring and de-monopolization of the Russian power sector. The company was spun off from RAO Unified Energy Systems (UES) of Russia and has 53 hydro-generating plants and a total installed capacity of 25.3 Mw. RusHydro also includes scientific research, design research, engineering and retail energy sale subsidiaries under its umbrella.

"We believe that converting our existing Regulation S GDR program into an OTC-traded ADR program is the next logical step in our effort to build liquidity. This upgrade will enable U.S. investors, both institutional and retail, who were previously unable to invest in our company, to purchase RusHydro's stock in Russia, London and New York," said Vasily A. Zubakin, RusHydro's acting chairman of the management board. "We anticipate further expansion and diversification of our shareholder base as a result of this transaction and as a result of the value-added services provided by BNY Mellon."

"BNY Mellon played an instrumental role in the creation of RusHydro during the broad restructuring of Russia's energy sector by helping to reorganize UES into 25 new subsidiaries," said Michael Cole-Fontayn, chief executive officer of BNY Mellon's Depositary Receipt business. "We're honored to have been selected by RusHydro for our unparalleled expertise in the DR market."
