(Much of New Orleans is below sea level. It is critical they generate enough electricity to keep the drainage pumps operating at full capacity. Saturated soil within the levees and flood walls could lead to failure.)

"A slow-moving Hurricane Ida has left all of Orleans Parish customers without power due to “catastrophic transmission damage.”

BREAKING @WWLTV: New Orleans Sewerage & Water Board has lost all three feeder lines from Entergy. That means the agency lost 12 megawatts of 60-cycle power to run its newer drainage pumps and is left with only Turbine 6 to make 15 megawatts in-house. #HurricaneIda

“Although we have lost all Entergy power, our teams are working quickly and decisively to make up for this with our self-generated power sources, including Turbines 4, 5, and 6 and EMD, as well as backup generators located at our drainage pumping stations. The Entergy loss of power is a significant loss of power for our 60 hz pumps and the 25 hz pumps we power through the frequency changers, but we are using our self-generated sources of power to drain stormwater and pump drinking water into the city. This power loss also impacts our sewer pumping stations. Currently there is no backup power to operate any of those that were impacted. We are assessing how many of the 84 stations are impacted but the number may be very significant. We have worked to obtain backup power for some of these stations & we will mobilize those units when it is safe to traverse the city. In order to prevent sewage backups, we have asked residents to limit water usage at home, thus decreasing the amount of wastewater we must remove."
