Smart Grid Solutions
CGI Commitment Overview
Tollgrade Smart Grid Solutions
Clinton Global Initiative “Building a Predictive Grid in the Motor City”
Key Objectives: Predict & prevent outages Eliminate 500,000 outage minutes Save $10,000 per outage avoided Integrate sensors with Tropos network Create “green jobs” Lower DTE Energy’s carbon footprint
Tollgrade Smart Grid Solutions
Data Reporting Goals Predictive Grid at DTE Energy Classify events that could be prevented in the future Proactively respond to events that can be corrected
Create an industry benchmark to measure events Share findings to improve outage detection across US Look for trends and lessons learned that can help prevent
outages nationwide

Example: Predict Voltage Regulator Failure
Line Disturbances detected; troubleman found failing voltage regulator 2,000 customers would have been impacted with an outage Prevented 3 hour outage in December Sensors were on line less than 6 weeks
Tollgrade Smart Grid Solutions
Example: Help Restore Power After Storm
We detected the outage that impacted 6,000 people Notified the crew in less than 2 minutes Reduced outage time by 13 hours; saved the utility $2M Roads were impassable, sensors directed crews to the exact
switching location to restore power faster (and more safely)
