CARMEL, Ind., July 25, 2012 /PRNewswire/ -- As soaring temperatures continue across the United States, MISO successfully managed the demand for electricity in its footprint Monday, July 23, while setting a new all-time record for energy use in the region. The regional transmission system operator, which manages the flow of energy across high voltage lines in 11 states, saw the demand for energy use reach 98,576 megawatts (MWs).  The peak was recorded at 3:54 p.m. (EST).

Today's demand is expected to be about 93,000 MWs, but Conservative Operations have been declared for the region because of continuing high temperatures.

"MISO's real-time operations teams in Carmel, Ind., and St. Paul, Minn., are instrumental in anticipating and effectively managing high demand for energy.  MISO works closely with Local Balancing Authorities and generation owners to confirm operating needs and capabilities in order to maintain grid reliability," said Vice President of Operations Richard Doying.

MISO issued Conservative Operations and Hot Weather alerts Monday around noon suspending transmission maintenance and conducting a review of outage plans for deferral and cancelation.

"We will continue to monitor the heat wave and the demands felt in our footprint throughout the week to ensure reliable operations of the electric transmission grid," Doying added.

A new peak load was also set Monday for the MISO reliability coordination area. The peak was 104,669 MWs also recorded at 3:54 p.m. (EST)
