“Atos Origin Builds New National Control System (SNC) for France’s Power Transmission Grid”

Paris, January 13, 2005

SNC system used to monitor France's extra high voltage power transmission grid

Atos Origin, a leading international IT services provider, has designed and built the National Control System (SNC) for France's power transmission grid. Commissioned on June 28, 2004, the system was built on behalf of grid operator RTE, a public utility that operates, maintains and improves the French electricity grid. The SNC system was developed to replace the SYSDIC system, introduced in the early 1980s and approaching obsolescence, whose hardware could not be upgraded or scaled to handle the entire extra high voltage grid (400 kV and 225 kV).

As part of a program to upgrade its remote control network, RTE selected Atos Origin to build a highly reliable, real-time, next-generation system to supervise France's extra high voltage (400 KV and 225 KV) power transmission grid and tailor supply to demand in France and neighboring countries.

RTE ensures a continuous supply of power to some 30 million customers across France. Because electricity cannot be stored, output has to match consumption at any given moment to guarantee uninterrupted service. In addition, the power delivered has to meet specific quality criteria, such as frequency and voltage, and has to be generated as affordably as possible.

Based on Atos Origin's ADACS application platform, the new remote control system provides operators with decision support and network supervision applications, with guaranteed uptime of 99.97%. The volume of data processed is extremely high. For example, SNC acquires 10,000 remote readings every 10 seconds and monitors the status of 26,000 remote signals.

The SNC system was commissioned after 15 months of supervised operation, during which time a complete picture of the 225 kV grid was obtained, maintenance procedures were fine-tuned and further functions were introduced.

Atos Origin is also providing through-life services for the system for five years, beginning October 1, 2004.
