ITC Midwest Derecho Impact and Response

On August 10th the largest single storm event in the history of ITC Midwest affected the transmission system.  At the height of the storm over 145 individual circuits where out of service.  Over 500k electric customers were without power stretching from Des Moines to Clinton, IA.  The storms 40 mile wide path cut right through the heart of ITC Midwest’s transmission system.  The entire employee pool for the company went to work within hours of the storm and eight days later energized the last distribution substation with power.  The presentation will cover the effects and recovery from the storm and how the engineering team designs and builds resilience into the transmission system to serve our customers.

Alliant Energy - Restoring Power After the Derecho

John Boston, Director of Engineering at Alliant Energy, will discuss how Alliant Energy worked as quickly and safely as possible to rebuild the electric system and restore power to customers.

The presentation will also cover how Alliant Energy managed resources effectively, utilized advanced metering infrastructure (AMI) data to validate outage information and the logistics of dispersing the massive amounts of materials needed to restore power.
