This is the last post, thsnks to the board for besring with me on this OT thread.


Exactly! I am a technician , for some years my specialty was telecom power.

I was in South East Texas for Rita and Ike. During Rita a bug part of South East Texas was without power for over a month.

Typically, you can run a diesel generator for 100 hours before a specialist of some sort will need to be on site. That is four days. Also, even with outstanding service and maintenance we had 5 to 15 percent failure rates in our generator fleet when they were put into long duration runs.

We typically keep 4 to 24 hours of battery backup at each telecom site. Some have much more, mainly because the equipment is more energy efficient.

I ran a bunch of numbers and figured that we could run a portable generator site to site after 100 hours, and we could put in 200 hours of battery backup and we could use the excess 100 hours as power arbitrage. (The Phone Company is in the telecom business not power, so no solar panels for us)

At 100 dollars a kilowatt hour, the cost for the battery plant become the cost for the battery plant plus the Diesel Generstor plus the transfer switch.

Of course that is installed cost, with ancillary equipment. So a factory cost of 50’a kilowatt hour is probably what is needed, or lower.

We will get there.

Probably be 2030.
