Calculating Natural Gas Requirements for a 1000MW Power Plant

[mbm]

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?

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?

 

[mbm]

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
