You'd generally know if it's the case, but some industrial units include nitrogen service along with your regular utilities (gas, water, hydro). Depending on how they get their nitrogen, you either pay by the unit or you pay for your maximum flow rate. The one occasion I was in this situation, I think we payed $50/mo for 1l/m. The particular unit included shop air for free and I think you could include O2, but it wasn't cheap.
