LCG, Aug. 2, 2001--The Midwest Independent Transmission System Operator Inc. yesterday began 45 days of market trials, a series of validations and drills it hopes will demonstrate its ability to operate the first regional transmission system in the Midwest.

"With the help of our transmission owners we are beginning the readiness demonstrations that willtest all of our systems, from the initial point when transmission requests are made to the time whenthe bills are issued," said Michael J. Gahagan, chief information officer.

The ISO said it will conduct drills in the following operational areas: transmission market activities, tagging and scheduling, flowgate verification, transmission (operational) planning, security coordination, security response, outage scheduling, maintenance coordination, 24x7 operations and daily and monthly settlements and billing.
