You plan off grid remote generation? How big is "industrial?"
These projects generally start as spreadsheet exercises by a contract electrical engineer. You tell the engineer your budget, and resources, and get a flow chart, a spreadsheet and project plan.
You might start to project-plan it by first defining your load, or demand.
Then ask, is the load sporadic, or non-stop?
Then, consider fuels available.
You will want to use the lowest-cost fuel.
For example projects with large non-stop load - like smelters - will generally locate in a country with low-cost hydro generation.
So once you know your load, load type, and local fuel source, you can consider generation options; hydro, oil, solar, gas, coal. Your contracted engineer would know the options and vendors, and costs. Thats what you pay an engineer to do. Feasibility studies.
Then the environmental approval process begins......all of this can take two years at least.
Also each area will have its electricity rules and usually, if a local pool exists, all units over (say) 30MW must by law, be dispatched centrally.
