Paris, October 14, 2010

Alstom Grid has signed a €12 million contract with Egyptian Electricity Transmission Company
(EETC) for the supply and delivery of an Energy Management System (EMS) replacing the existing
National Control Centre in Giza and its back up in Abassia. The project also aims to replace and
expand EETC’s telecommunications network, connecting to existing systems throughout the country
with full digital technologies.

EETC will benefit from Alstom Grid’s world-leading e-terra suite of EMS software applications to
secure greater and efficient grid reliability, stability, security and management of interconnections
with neighbouring countries, Libya and Syria through Jordan at optimized cost. The solution also
includes a market management system (MMS) that can provide EETC with real time information on
tariffs to both producers and consumers. This will allow the opening of the Egyptian Electricity
Market, a regional first, when EETC decides to launch the application.

Egypt is the second African country to decentralize its electricity market (the first was South Africa).
It has become a high technology energy player and a model for further decentralization projects in
Africa and the Middle East.

“We are delighted to partner with EETC in its ambition to stay at the forefront of technology in the
region,” said Jean-Michel Cornille, Senior Vice-President for Automation at Alstom Grid. “As a global
leader in Smart Grid-ready management solutions, and strategic technologies like power electronics,
automation and control room IT, Alstom Grid focuses on intelligent solutions that respond to the fast
evolving challenges of energy efficiency, network reliability and stability, and the integration of
renewable energy into the grid.”

With this new National Energy Management System, Alstom Grid consolidates its leadership
position in the Middle East, managing around 70% of the region’s energy flow. Looking at total
African Transmission System Operators, Alstom Grid technology will manage more than 70% of
Africa’s electricity flow, with national grid operations in Burkina Faso, Ethiopia, Ivory Coast, Libya,
Senegal, South Africa, Tanzania and Tunisia.
