You can't charge 800 buses in Torino but you can charge 8000 in Shenzhen? What's wrong with the Italian grid if this is true?
Population of Shenzhen: 12.5M or 23M for the metropolitan area (https://en.wikipedia.org/wiki/Shenzhen)
⇒ the Torino grid need not be worse than the Shenzhen one for that to be true.
Shenzhen has a modern smart grid designed to accommodate EV charging. It seems likely that BYD and other Chinese EV makers will quickly take over the global vehicle industry. It is the end of an era for european car makers, killed off by environmental regulation and penalties, and EV subsidies
You literally need to build new substations and wires to service a fleet of busses. I think there is probably generation capacity but it might not be deliverable to where it’s needed.
Generation charges: $22.33
Peak Usage: 62kWh @ $0.29672
Off-Peak Usage: 258kWh @ $0.28243
Baseline Credit: 246kWh @ -0.0832
Total usage: 320kWh @ $0.2160/kWh
As those plants age out of their usable lifetime, Kentucky utilities will have to choose between some combination of renewables and storage or natural gas or nuclear, all of which have higher costs than operating the defunct coal plants, but lower capital costs than building new coal plants. This will result in a rise in their prices over time.
Of course, comparing the future costs of new non-coal plants doesn't account for the huge existing public health and environmental costs of burning coal for electricity, which would be avoided by any of the other technologies.
I’m hoping Kentucky starts to do more solar as it is pretty decent for sun, but the local politics likely think solar + stationary battery storage is some lib-ruhl conspiracy.
