MLGW News Release
MLGW prepares for TVA to re-issue Step 50 curtailment
December 24, 2022
Some Residents asked to limit Water Usage
(December 24, 2022, 12 a.m.) The extreme cold temperatures and high demand across the TVA service territory continue to cause a critical power supply situation and low water pressure.
MLGW hasn’t initiated rolling blackouts this evening but is preparing for the possibility for TVA to re-issue a Step 50 Curtailment which means that all local power companies are required to drop between 5 and 10 percent of their total electrical load. This is necessary to avoid major outages across the MLGW and other local power companies service areas.
Based on TVA’s current system status and stability, we do not expect rolling blackouts overnight but are preparing for increased risk starting around 6 a.m. Saturday, December 24.

This means that service to an area will be interrupted for 30 minutes. Customers may experience outages two to three times a day on average. All customers in MLGW’s service territory could be affected.
Critical facilities such as water pumping stations, sewage treatment plants, hospitals and airports are excluded from these blackouts.
Rolling Blackout Plan
MLGW has recently update the process by which rolling blackouts will be implemented. Customers can review the plan at and determine when their neighborhood might be impacted. Should an order be issued overnight or early a.m., MLGW will begin with Group 2 (areas of North of Downtown, vicinity of Ben Hooks Library, and North Germantown) and then proceed with other areas in order as necessary (see website for details).
Water System Update
Residents in Southeastern Memphis and Southeastern Unincorporated Shelby County are currently experiencing low water pressure. As a result, a boil water order has been issued for the following areas shown in the maps below.
Customers in this area SHOULD NOT DRINK THE WATER WITHOUT BOILING IT FIRST. Bring all water to a boil, let it boil for three (3) minutes, and let it cool before using, or use bottled water.
Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice. Boiling kills bacteria and other organisms in the water. Tap water is safe for bathing and showering but try to avoid getting it in your mouth.
For more information, see:
Additionally, customers in these areas are asked to limit water usage to essential use only until further notice.
We apologize for the inconvenience and appreciate your patience.

MLGW is the largest three-service public power utility in the nation, serving more than 440,000 customers in Memphis and Shelby County.
