Steam Costs Cogeneration
(OP)
Anybody know how i can calculate the marginal costs of steam generated through cogeneration or have any rules of thumb? ($ per unit of usable heat energy)
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Am I missing the point?
If you prefer to allocate costs to steam and electricity, then you could do something like this:
fuel charge x (kW of heat)/(kW of elec + kW of heat)= cost of heat

"....exactly zero".
If only it were true! Demin water, feedwater treatment chemicals, cooling tower make-up water, more chemicals, etc all need to be factored in. Sadly none are free.
