Q3. [30] An ice-cream plant is equipped with a 600 kWe cogeneration system. The plant has three operational characteristics through the year; 1- non-operational day, 120 days 2- 16-hour operational day, 120 days 3- 24-hour operational day, 125 days According to following table which shows load profile for three operational characteristics, calculate; a) The average load factor for each operational characteristic b) The electricity energy generated per year (MWh/year) for each operational characteristic c) Electricity efficiency of cogeneration Assumptions: - Natural gas bill is $200.000 Time 12:00-16:00 16:00-20:00 20:00-24:00 24:00-04:00 04:00-08:00 08:00-12:00 Daily Data Non-operation days Electrical kw 320+2*Row# 300+2*Row# 310+2 Row# 160+2 Rowl 170+2*Row# 300+2*Rowll - Natural gas cost is $0.0216/kWh. - The engine can vary its output down to 50% after which is must be shut down.
