Those are some great graphics.

Does the new entergy west power substation actually address this problem? I’d love to see that same graph after completion of the substation.

The lakeview and midcity pumps on that graph run on 25 hz. When the pumps are on and functioning they really do move an incredible amount of water.

We can never fix our crime problem because our people are kind of retarded and awful, but maybe drainage will actually improve with reliable power.

The water actually went down just as fast if not faster than it came up last night.

The pumps were working, they were just overwhelmed

So they have to build frequency converters (which are being built now) to take the 60Hz Entergy Substation feed and convert to 25Hz for the old pumps. The substation will be significantly more reliable than their current power feed from Entergy (think like a large chemical plant).

Ultimately they will have much more reliable power with the substation as primary and then the older power plant turbines as emergency backup. Then they will replace those turbines with new ones for backup power.

It’s a lot of interconnected power and pumps work and they just don’t have the funds for $1B investment all at once.
