Calculating Natural Gas Requirements for a 1000MW Power Plant

Click For Summary
SUMMARY

The calculation of natural gas requirements for a 1000MW power plant reveals that approximately 2.4 x 10^8 standard cubic feet (SCF) of natural gas is needed per day, translating to an input of 2.4 x 10^11 BTU/day. The efficiency of the gas-fired turbine generator, which is about 50%, significantly impacts the amount of natural gas required. If the efficiency were to decrease to 10%, the natural gas requirement would increase proportionally, demonstrating the critical role of efficiency in energy production calculations. Converting energy outputs to SCF/year is essential for accurate long-term fuel planning.

PREREQUISITES
  • Understanding of thermodynamic efficiency in power generation
  • Knowledge of energy conversion units (BTU to SCF)
  • Familiarity with natural gas consumption metrics
  • Basic principles of electricity generation from gas-fired turbines
NEXT STEPS
  • Research the impact of turbine efficiency on fuel consumption in gas-fired power plants

Homework Statement



a gas fired turbine generator for producing electricity has an efficiency of about 50%. how many cubic feet would be needed to produce 1000MW for one year.

Homework Equations



2.4 x 10 ^8 SCF/day is the natural gas required for the power plant
input = 2.4x10^11 btu/day

The Attempt at a Solution


i assume the input times 365
btu/day can be converted to bbl/day
bbl/day can be converted to find out the quantity of cubic feet
but what role does the 50% efficiency play in the answer?
 
Physics news on Phys.org
Where does the bbl/day come from? Don't you think if the plant was 10% efficient, instead of 50% efficient, that the amount of natural gas required to produce 1000 MW would change?
 
the bbl/day quantity is a fuel requirement for a 1000MW power plant

I was giving the problem some thought, the 1000MW can be converted to SCF/year and afterwards use the equation efficiency= output/input to obtain the input in SCF/year
instead of using the SCF/day
