Where are you getting the 200 megawatt number from?

The document you linked says that a large auto assembly plant consumes around 188,000 MWh annually (with regional variation). By my quick math that is less than 22 megawatts baseline load (24/7/365).

There is a mention that natural gas and other fuels being used on-site, are you converting those to MWh equivalent? I'm not as familiar with that conversion, but from a quick online calculator I found it would still be under 75 megawatt for electrical and fuel-equivalent combined.
