Alstom and Midwest ISO prepare to go online with 45-day market trial

BELLEVUE, Wash., September 5, 2001 – ALSTOM today announced that the Indiana-based Midwest Independent System Operator (MISO) has taken the initial step prior to “going live” as the first operational regional transmission system in the Midwest with the launch of a 45-day market trial.

ALSTOM is the prime contractor on the $47 million USD project, which will enable MISO to reliably operate the largest and lowest-cost electric transmission grid in the United States. Upon project completion MISO will become the largest Federal Energy Regulatory Commission (FERC)-approved Independent System Operator in the United States.

“A successful market trial will demonstrate the ability of the not-for-profit consortium of transmission companies to meet its December 2001 goal of operating as an integrated system that works across multiple corporate interfaces,” said Norris Peterson, MISO Project Director for ALSTOM ESCA, the Energy Management and Markets Business Unit of ALSTOM.

This new system will make it possible for MISO to match energy demand with available transmission capacity – through the use of congestion management techniques – thereby ensuring the reliable delivery of power. Additionally, through the use of the Internet and web-based forms, market participants can quickly and easily enter the marketplace.

When implemented, this new system will be capable of managing the entire financial cycle, ensuring accurate cash flow from the user of the grid to the owner of the grid.
