RTI conducted a major investigation of a generating station cable fire and a subsequent substation switchgear and transformer fire, which occurred within days of each other.  The first fire interrupted service to 40,000 customers for up to 3 days, and the second fire left 25,000 of the same customers without service again, this time for up to 12 hours.

RTI served as the lead technical investigative firm for the State of Illinois and coordinated, managed, and oversaw all team members' activities relating to the investigation.  Extensive testing was also performed.

Specific loss prevention and fire protection recommendations were proposed by RTI.

Visual demonstrative evidence was produced, as well as published findings in the official State report on behalf of the Illinois Commerce Commission.
