Fuel costs, maintenance, and operation would be over $2M.

Normal energy prices are about half of what you quoted. It's TBD if they come back down to normal in the near future in the EU.

You're looking at $18M in revenue. This thing will probably cost more than $10M to purchase, and then you need land, a grid-tie in, and permits.

It would still work - but the numbers aren't going to look as good as wind & especially solar.
