TVA is asking people to conserve power in this time of high usage

So, they want the everyone to buy an EV.

Hell, they can't even provide juice to heat homes.

The average electric vehicle requires 30 kilowatt-hours to travel 100 miles — the same amount of electricity an average American home uses each day to run appliances, computers, lights and heating and air conditioning.

Typical of a well thought out 'gubmint' plan.

I worked for that communist organization back in the 90's.

Can't believe Congress hasn't broken it up yet.

Maybe if they kept those fossil plants online, they'd have enough generation capacity.

At one time, TVA had plans for 17 nuclear reactors along the Tennessee River from Tennessee to Alabama to Mississippi.

Only 7 were built and operational today.

Thanks, Three Mile Island (conspiracy theory, anyone?),

My older brother retired from there and said the same thing.

Too much money involved. Too many kickbacks from contractors.

Remember that more people died at Chappaquiddick than at Three Mile Island.

Wood stove for heat. Propane tankless water heater and range. I could power fridges and freezer w solar if needed.

The plant that failed in last year's cold was a 1967 coal plant. It is slated to be replaced with a NG plant. Only 3% of TVA's power comes from wind and solar. Most is nuclear and hydro. TVA's future clean energy plans rely on NG, small nuclear reactors, solar, and wind, in that order.

That is predictable, consistent demand which would result in investment of new power sources. A random spike in use does not result in new investment since it is not consistent and predictable.

Energy grids are built for peak demands.

Will these cars be charged consistently throughout the day?

Based on Entergy rate of about 12 cents a kWH that is about 3.60 in electrical power consumption per 100 miles, but if I use a supercharger for 36 cents a kWH, that comes out to over 10 dollars in electrical costs.

Fuel costs average about 3.00 dollars a gallon which will get you about 27 miles per gallon.


Based on this you are not saving much by going EV, and then you have worry about issues such as the battery not charging as much due to the cold or using extra power to keep the battery warm.

At least with a gas engine you get free heat as a byproduct of combustion, and most engines will turn over in a cold morning with just a switch. Now in an extreme cold setting like Alaska, you may want to plug in a block warmer.

There’s currently more coal than natural gas and nuclear combined generating on MISOs grid. There are over 38 gigawatts firing right now and it’s supposed to be coming off the grid at the same time we ramp up EVs. How are you wanting to replace 38 gigawatts and add additional load on the grid at the same time? This is supposed to happen by 2030. What source are you proposing and what are the general logistics?

I don't understand why the mainstream population doesn't get this. EVs sounded pretty cool when charging stations were free, but that's not the case anymore. People need to catch on to that.

Natural gas furnace in my house. My whole house is pulling like 18 amps right now.

That'll make at least 31 DeLoreans very happy.

I read an "article" this morning lauding a new 565 MWh Tesla battery installation "replacing" a 180 MW coal unit on Oahu. They're hanging on to that trash burner and combustion turbines for while longer though. Thankfully, those don't release carbon to the atmosphere. /sarcasm
