News Summary

Over 100,000 customers in southeast Louisiana faced a significant power outage on May 25 due to a ‘load-shedding event’ caused by MISO. The incident raised concerns about grid reliability as multiple local officials criticize the lack of communication and preparedness. Investigations by the New Orleans City Council and the Louisiana Public Service Commission are set to explore the causes of the outage, particularly in light of upcoming summer demands. Entergy has restored power but faces scrutiny over its handling of the situation and infrastructure readiness.

Southeast Louisiana

More than 100,000 customers across southeast Louisiana experienced a significant power outage on Sunday, May 25. The outage was initiated by a directive from the regional power grid operator, the MISO (Midcontinent Independent System Operator), leading to widespread disruptions affecting areas including Orleans Parish, Jefferson Parish, St. Bernard, and the Northshore.

The unexpected outage commenced shortly before 4:30 p.m. and has been labeled a “load-shedding event” by Entergy, which refers to a controlled power cut aimed at preventing more severe damage to the electric grid. This decision followed the unexpected trip offline of the River Bend Nuclear Generating Station and a scheduled maintenance shutdown at Waterford power plant.

In response to the incident, the New Orleans City Council and the Louisiana Public Service Commission are planning to conduct investigations into the reasons behind the mass power outage. Public Service Commissioner Davante Lewis has criticized MISO for its failure to accurately forecast energy demands and prepare additional energy sources ahead of planned maintenance schedules. Criticism was echoed by Councilman JP Morrell and Council Vice Chair Helena Moreno, who voiced frustration over the sudden nature of the outage and the lack of timely communication from the utility companies.

As a result of the outage, several Sewerage and Water Board lift stations were impacted; however, no significant damage has been reported. Local businesses also felt the strain, with reports of financial losses from bar owners who had planned for busy events during the outage.

The power disruption raised alarms among local officials regarding the reliability of the power grid as southeast Louisiana nears the hotter summer months, when energy demand typically swells. St. Tammany Parish President Mike Cooper deemed the power cut “unacceptable,” emphasizing the necessity for improved infrastructure and diversified energy sources.

Multiple critics are voicing concerns about the grid’s reliability and the urgent need for investment in initiatives that will strengthen connections between Entergy and other energy sources. Reactions to the event are already leading to discussions about coordinating future hearings to analyze the outage’s causal factors and the responses from utility companies to enhance preparedness for potential incidents.

Power was fully restored to affected customers by Monday morning, as Entergy continues to work on understanding the directive from MISO and the conditions that precipitated the widespread outages. Entergy has confirmed the planned maintenance at Waterford; however, they have yet to address the complications surrounding the River Bend plant’s unexpected failure.

As investigations proceed, ongoing scrutiny will focus on MISO’s demand forecasting shortcomings and the inability to provide sufficient warning ahead of the outage. This incident may catalyze broader discussions on energy management in the region and the essential infrastructure improvements needed to bolster system reliability for the future.
