Entergy, MISO Ask Customers To Limit Electricity Usage

January 18, 2018


Entergy is asking its customers, including those in Texas, to limit electricity usage Thursday morning.

Power reliability coordinator Midcontinent Independent System Operator has requested Entergy customers to voluntarily reduce electricity usage between 5 a.m. and 11 a.m on Thursday.

MISO alerted several energy providers Wednesday that its power grid had reached maximum generation.

If the load could not be lightened, MISO said it would have to “shed” communities in order to stabilize the grid, according to the Natchez Democrat, but power demand appeared to recede Wednesday afternoon.

Entergy stated Wednesday night:

“MISO is making this unusual request because use of electricity could exceed available generation, due to higher than expected demand for power and unexpected power generator outages within the MISO southern territory.

“MISO is working to bring on additional generation in the area.

“The higher than expected demand is because of the unusually cold temperatures that moved into the territory over the past few days.

“MISO is making similar requests to utilities across the Midwest, including other utilities near our service area. If the power supply cannot meet the demand, then periodic power outages would be needed.

“’We apologize for any inconvenience.’ said Vernon Pierce, vice president of customer service for Entergy Texas, Inc. ‘The arctic blast is driving up electricity usage. This is an unusual situation MISO is working to correct as soon as possible.’”

“Pierce added that the request does not apply to elderly customers or those with special health concerns.

“Entergy joined MISO, one of the nation’s largest regional transmission organizations, in December, 2013.

“MISO comprises a pool of electricity generators and users that stretches from Canada to the Gulf of Mexico.”
