MISO supports member restoration efforts from Hurricane Laura

The Midcontinent Independent System Operator (MISO) is responding to the impacts of Hurricane Laura across the South Region. Initial assessments by our member companies indicate widespread damage in south Louisiana and southeast Texas. Today, MISO escalated to the most severe step in its emergency actions in order to avoid a larger power outage on the bulk electric system in the affected areas. 

“MISO has implemented Emergency Operating Procedures to address reliability in a load pocket of the region that experienced significant damage from the hurricane,” said Renuka Chatterjee, executive director — system operations. “While we continue to support our members’ restoration efforts in the South Region, we maintain our focus on ensuring grid reliability across the entire footprint.” 

Because of the significant storm damage to the transmission system MISO directed Entergy, one of its member companies, to begin periodic power outages. Ahead of the storm, MISO issued a Conservative Operations Declaration as well as a Severe Weather Alert for the South Region.  The MISO declarations and alerts may be extended, or additional declarations and alerts may be issued.

In addition to the storm-related conditions in the South Region, MISO’s Central and North Regions experienced high temperatures combined with challenging capacity availability. In response to these conditions, MISO issued a Hot Weather Alert for the Central and North Regions. MISO is in close coordination with member companies and counterparts such as Southwest Power Pool (SPP) and the Electric Reliability Corporation of Texas (ERCOT) to ensure reliability of the grid. MISO has multiple redundancies built into the system and back-up operation facilities to ensure a smooth transfer of all operational MISO functions.

“We continue to work with our member companies and partner RTOs like SPP and ERCOT toward a speedy recovery,” said Daryl Brown, executive director — South Region. “Mutual assistance and collaboration before and during the storm as well as throughout restoration are necessary to maintain our focus during times of crisis.”
