Alcoa, RUSNANO and Holding IDGC Sign Memorandum of Intent to Produce Nano-coatings for Power Transmission Grids

June 20, 2011

ST. PETERSBURG, Russia & NEW YORK–Alcoa (NYSE: AA), OJSC RUSNANO and JSC Holding Inter-regional
Distribution Grid Companies (JSC Holding IDGC) signed today a Memorandum
of Intent to establish a joint venture for the development and
production of nano-coatings. The memorandum was signed at the St.
Petersburg International Economic Forum by OJSC RUSNANO Chief Executive
Officer Anatoly Chubais, Alcoa Chairman and CEO Klaus Kleinfeld, and JSC
Holding IDGC Deputy Director General and Technical Director, Boris

The joint venture will produce a broad range of applications including
anti-icing nano-structured coatings for ground cables, wires and other
components of power transmission lines. The project also includes
production of next-generation wires and cables with improved
conductivity and anti-icing properties for JSC Holding IDGC companies.
Alcoa and RUSNANO joint venture will look to install a pilot production
line for the application of nano-coatings. JSC Holding IDGC, in turn,
will support implementation of corresponding research and development,
tests and certification of new high-tech products.

“It’s well known that icing and rupture of power transmission lines due
to inclement weather conditions is one of the most acute problems for
Russian power engineers,” said Chubais. “We expect our joint development
of nano-coatings for existing power lines and future production of
next-generation cables will fix that problem.”

Kleinfeld added: “Alcoa and its partners RUSNANO and JSC Holding IDGC
offer unique technological and production capacity. Together, we hope to
open new opportunities for the aluminum industry in Russia.”

JSC Holding MRSK Director General, Nickolay Shvets, concluded that last
winter’s “icy rain” were proof of the need for wires with anti-icing
properties. The technology will reduce power outages and increase
service life. “Producing next-generation wires and cables in Russia to
meet the demands of the country’s power distribution grid will be an
important step in improving system reliability of power supply to
consumers,” he said.

Alcoa first entered Russia in 1993. In 2005 the company acquired two
Russian largest fabricating facilities: Samara Metallurgical Plant (now
ZAO Alcoa SMZ) and Belaya Kalitva Metallurgical Production Association
(now ZAO AMR). Since 2005 Alcoa has invested over $750 million to
upgrade its Russian facilities.

JSC Holding IDGC is a Russian company operating in power
engineering, which structure unites interregional and regional power
distribution grid companies (MRSK/RSK), institutes of scientific
research and research and development institutes, as well as
construction and sales organizations. 97 branches of MRSK/RSK are
situated in 69 subordinate entities of the Russian Federation. Grids of
10 power grades from 0.4 to 220 kV are in the sphere of JSC IDGC Holding
companies responsibility. The overall length of JSC Holding IDGC
affiliated operating companies’ grids exceeds 2.1 million kilometers.
The Holding IDGC is one of the world’s largest power grid companies in
power distribution grids length and number of consumers. The overall
volume of power transfer in 2010 was 591 billion kW/hour. The IDGC
Holding groups numbers around 190 thousand qualified experts responsible
for reliable and quality transfer and distribution of power, providing
consumers technological involvement services.

OJSC RUSNANO The opened joint stock company RUSNANO was
founded in March 2011 by restructuring of State Corporation “Russian
Corporation of Nanotechnologies”. The OJSC RUSNANO performs the state
policy on development of nanoindustry, being the co-investor of
