Transcribed Image Text:A combined cycle plant with a capacity of 500
MW, which participates in the Mexican
wholesale market, has the following
performance curve:
f(p) = 250 + 3.1 * p + 8.5 * 10-3 *
(MMBtu/h)
Where the power, p, is given in MW.
a) Calculate the Heat Rate, expressed in
Btu/kWh, when the plant operates at 250 and
500 MW.
b) Calculate the efficiency, expressed in %, when
the plant operates at 250 and 500 MW.
c) Considering that the cost of natural gas is 4.0
US$/MMBT., obtain the average cost of
electricity, related to the price of fuel, expressed
in $/MWh, when the plant delivers 250 and 500
MW to the grid electrical.
