nearly 70% of all electricity currently uses natural gas as the fuel source.
Maybe locally where you are, but nationwide it's 40%.


There's just something fundamentally wrong with using a natural gas generator to drive a turbine to charge an electric truck :)
Not really--it is more efficient and less polluting than burning diesel within the truck, and it makes it much easier to substitute even cleaner energy sources for the truck in the future.

Instead of going underground you might consider using bus bar above ground.
I am not a fan of outside busduct...seen too many fail even thought they were rated for outside installation. I replaced a lot of outside busduct with cable bus for one client as a preemptive way of preventing busduct failure

Yes, need a 2 meg wind turbine on site. No wind or not enough wind, you can't charge today :D
Once they get the small modular nuclear reactors in service, I would see those as an answer for supplying power to this type of installation.

The usable power claimed from wind turbines is a total fraud. I have investigated this for years and this is what I have found. Wind power doesn’t make power, it makes money for a small group of people. Look at the current wind power situation: The landfills are piling them up.

I doubt the EIA has been snookered, and they say (per the previous link) that in 2022 wind power generated 434 billion kWh, or 10.3% of US electricity generation.

Generation and useable power are different. That’s the basis of the wind energy scam.

Please explain how wind turbines stay in phase also.

Production and usage of deliverable power. Wind enthusiasts use “production power” in statistics and data. They don’t know what production was actually used.
 
There's probably an armature involved, too. (The question is to generate DC and use a grid-sync'd inverter or to generate AC and use a governor to control the prime mover; once the rotating generator is connected to the grid it'll stay in sync unless something rather catastrophic happens. That's a topic for another thread.)

Back to the OP, the NG turbine is the correct method. The demand charges with Pacific Power are $15.50 per kW. That’s $28,000 per month in demand charges for ONE truck charger. The lease and gas costs of the oil rig turbine are about half of that.
