Tollgrade, DTE Energy to improve power grid with Clinton Global Initiative project

Tollgrade Communications Inc. has partnered with DTE Energy in a Clinton Global Initiative (CGI) project for a comprehensive grid modernization project in Detroit that will roll out over the next three years.

Tollgrade’s commitment, “Building a Predictive Grid for the Motor City,” will be featured on stage during the closing plenary session moderated by President Bill Clinton at the CGI America meeting in Denver, Colorado.

DTE Energy is headquartered in Detroit, Michigan, and delivers electricity to 2.1 million customers. DTE Energy is deploying Tollgrade‘s LightHouse MV Smart Grid Sensors and Predictive Grid Analytics platform at key substations and feeders within its distribution network.


With this CGI commitment, Tollgrade and DTE Energy are targeting to reduce nearly 500,000 customer outage minutes over the next three years in the DTE Energy service territory where Tollgrade’s LightHouse system is deployed.

It is estimated that U.S. businesses lose on average $15,709 every 30 minutes during a power outage. These losses add up quickly and cost the U.S. $104 billion — $164 billion nationwide.

Additionally, another $15 billion — $20 billion is lost annually due to power quality disturbances such as “momentaries,” which are short outages that cause clocks to blink, computers to lose their data or automobile manufacturing lines to stop unexpectedly, damaging equipment.

The Tollgrade LightHouse platform classifies “line disturbance” events that precede an outage and to accurately detect momentaries. Using the data provided by LightHouse, utilities can find and repair these events on their distribution networks so they can be resolved more quickly or avoided altogether.

As an additional part of their CGI commitment, Tollgrade will analyze and distribute a first of its kind Predictive Grid Benchmark Report to educate the industry and policy makers on the importance of taking proactive measures in advance of outages — a significant of grid modernization.
