: : I am trying to put a dollar number number on electricity we produce at the plant I currently operate. I operate a back pressure turbine that produces between 1 and 6 megawatts of power. I think electricity is purchased from the local utility @5.5 cents a kilowatt hour. How much money would it cost if I had to purchase the electricity I am producing if I was at a steady 1 megawatt for 1 hour?
: I think your question is what is the cost for my plant to produce a MW. Is this correct?
: A host of information is needed.
: 1. Water Rate (lbs stm per MW)
: 2. Fuel cost/per unit (gallon/lb)
: 3. Blr Efficiency (can assume 85%) or can figure out
: 4. Units of fuel used (Lbs, Gallons or other)
: 5. Steam Enthalpy to turbine
: 6. Steam Enthalpy from turbine
: 7. Feed water temp to blr (for blr eff)
: From the above a cost of fuel can be made. Maintenance, operations cost in manpower all come in too. I'm retired and bored. I'll do my best to figure it out.
