Yet, in spite of claims of TX being an island, customers all over the country are now being forced to pay energy surcharges specifically tied to the Feb 2021 TX event. It was a line item on my last bill. On Wed, Nov 17, 2021, 21:03 Sean Donelan wrote: > "Those Who Do Not Learn History Are

One exception: The Serval mesh project is specifically meant to address the situation of no Internet or cell access. Caveat: it hasn't been updated recently and the Google app store no longer has it. It is still available via F-Droid. It looks like it may be useful if one has a working network

Several articles have mentioned 8 transmission lines were lost to the hurricane (a single big event event). A casual reader might think 8 lines would offer an 8-way level of redundancy. My WAG is the reality of load vs capacity is more like a N-1 or N-2 redundancy, but that's really just a WAG.

Some TVs may also try to rescale the inputs, or enhance/process the image in ways that can improve perceived video quality. Things like increasing frame rates of sources that are lower frame rates (thus the 120 Hz and 240 Hz TVs that attempt to make 24, 30, and 60 FPS sources look better), or

It's the specific combination of current and voltage that is hazardous. Too much current, through/across the heart, is the main, potentially fatal, hazard. This is why 120v GFCIs trip near 5 milliamps (mA). (20-30 mA in the wrong place is too much.) A voltage pushes a current through a

Griddy's model makes sense for customers who have the ability to automatically shed load and switch remaining critical load to backup generation when wholesale prices spike above the cost of using the backup generation. Might also make sense if the minimum load after load shedding is small enough

Using the sample bill on the GA power website you linked, I see a bottom line price of $76.17 for 606 kWh delivered to the customer. That is effectively 12.57 cents per kWh. Utilities (both investor owned and coops) have a multitude of ways of hiding the effective price in a variety of fixed and

This isn't a data center specific answer but it may help explain upstream cost drivers that may factor into rates seen. For commercial and industrial customers, utilities will often measure and bill power demand in kW separate from energy in kWh. Energy may only be $0.04/kWh but demand charges can
