In 2026, the Midcontinent Impartial System Operator, or MISO, will start a South Load Pocket Threat Evaluation centered on Louisiana. Whereas the examine could sound technical, it’s related to the ten,000 New Orleanians who misplaced energy for 3.5 hours through the Could twenty fifth “loadshed occasion” – the facility outage that hit the town final 12 months. 

The danger evaluation will assist Louisiana deal with key questions across the loadshed occasion: why it occurred, tips on how to stop future outages, and who’s liable for grid reliability in Louisiana.

MISO manages the movement of electrical energy throughout 15 states, together with Louisiana. Its job is to steadiness the availability and demand of electrical energy in actual time, assist handle congestion on transmission strains, and stop large-scale outages. In easy phrases, MISO permits utilities like Entergy New Orleans to purchase and promote energy throughout state strains in order that electrical energy may be delivered to the place it’s wanted most.

This regional coordination issues in Louisiana, which imports about 14% of its electrical energy from neighboring states. With out grid entry, utilities would want to construct and keep extra native energy mills, which might elevate prices for patrons.

It might assist to match the best way the facility grid works to a ride-sharing app, like Uber. Throughout peak occasions, when provide is restricted and demand surges, costs rise rapidly. An interconnected regional grid helps keep away from these spikes by rising entry to produce from different states. That improves reliability and stabilizes prices.

The Could twenty fifth outage was linked to what we name “load pockets” –  areas the place electrical energy demand is excessive however transmission of outdoor power into the world is constrained. For New Orleans in Could, these constraints meant that though energy was accessible on the grid elsewhere, it couldn’t be delivered quick sufficient to the town, the place it was wanted most. 

If demand exceeds provide, it could trigger cascading failures of energy vegetation and different tools, resulting in a extra critical grid failure. To guard the broader grid, MISO ordered a discount in electrical energy demand in New Orleans. This is called a loadshed occasion.

Load pockets in Louisiana will not be new. They’re the results of an under-developed electrical grid, they usually existed lengthy earlier than Entergy New Orleans and different Louisiana utilities joined MISO in 2013. A number of years earlier than that, in 2006, Entergy had recognized the necessity for transmission upgrades to deal with its clear constraints.

That’s the reason the Load Pocket Threat Evaluation is so essential. As soon as it begins later this 12 months, the examine will consider remaining transmission limitations and the elevated dangers that include rising demand and excessive climate. After analysts determine issues, they’ll transfer to proposing options to enhance reliability throughout southern Louisiana.

A well-planned regional grid protects towards load-shed occasions and likewise delivers very important financial advantages. Fashionable transmission methods cut back congestion prices, help industrial progress, and entice funding by offering dependable and inexpensive energy. 

Delays in that work have the alternative impact. Analysis constantly exhibits that delaying transmission growth will increase long-term prices for shoppers and limits financial alternative.

This work additionally comes at a essential second: Louisiana’s economic system and public security are more and more depending on dependable electrical energy, from hospitals and ports to knowledge facilities and emergency response. Grid Methods predicts that electrical energy use will develop 5.7% yearly over the subsequent 5 years, pushed by knowledge facilities, a rise in manufacturing, and electrification of business processes and manufacturing. 

Excessive temperatures and stronger storms are additionally inserting better pressure on our growing older electrical grid. 

We additionally want coordinated planning to organize for the addition of latest renewable power sources – together with wind and photo voltaic – which might be coming to Louisiana and at the moment are the lowest-cost expertise for bringing new electrical energy to the grid within the subsequent 5 years. Planning for these realities requires tangible, long-term coordination and transparency, not short-term reactions after outages happen.

Some policymakers have instructed that Louisiana ought to depart MISO following the Could load shed occasion. That’s not the answer. 

With out MISO, Louisiana would lose essential ties to a system designed to enhance affordability and handle threat throughout a broader area. Extra importantly, leaving now would halt priceless progress simply as MISO begins its examine aimed immediately at addressing South Louisiana’s grid challenges.

The upcoming Threat Evaluation will give Louisiana a roadmap to strengthen its grid and stop future outages. Through the use of data-driven evaluation to determine issues and discover options, the state can be sure that residents and companies have dependable, inexpensive electrical energy for many years to come back.
