ITCTransmission Announces Record Peak Demand on System

Aug 03, 2006

NOVI, Mich., Aug 03, 2006 /PRNewswire-FirstCall via COMTEX News Network/ -- ITCTransmission announced today that the transmission system in southeastern Michigan reliably supported the energy demand when it reached a new all-time record peak load of 12,762 MW yesterday following several days of near record temperatures in the metro Detroit area. This level of system demand was not anticipated to be reached until 2010 according to the "Forecast of Energy and Demand Requirements" published in the Michigan Public Service Commission's 21st Century Energy Plan.

"We are very pleased to see that our transmission system demonstrated outstanding performance and was able to meet the needs of the southeastern Michigan during this record-breaking week," said Joseph L. Welch, president and CEO of ITCTransmission. "Being able to reliably serve our customers is critical and is driven by three factors: effective operating practices; ongoing investment in rebuilding the transmission system; and efficient and focused preventative maintenance."

Since assuming responsibility for the transmission system in Southeast Michigan in 2003, ITCTransmission has invested more than $300 million as part of its annual capital and maintenance programs toward improving reliability and supporting increased energy demand.

"During periods of high system demand, ITCTransmission must remain focused on operating the system to ensure maximum system availability," said Elizabeth A. Howell, executive director of Operations. "ITCTransmission's system was able to meet this high level of demand without any transmission-related outages or voltage profile issues."

In order to maximize transmission system capacity, ITCTransmission ensured the availability of system equipment necessary to meet the increased demand by either returning equipment to service that was currently undergoing routine maintenance or by delaying removal of equipment from service for maintenance until the temperatures and system demand returned to a lower level.

"Completing our annual preventative maintenance plan along with the system capacity improvement projects are essential components of transmission system reliability and is ultimately what enables us to operate reliably during periods of high system usage," said Jon E. Jipping, senior vice president of Engineering. "Since becoming a stand-alone transmission company in 2003, ITCTransmission has regularly exceeded the goals set forth in its annual maintenance plan and significantly reduced the need for costly reactive maintenance thanks to our proactive preventative maintenance program."
