The levelized cost of energy (LCOE) for coal-fired electricity is about $0.09/kWh. Suppose the capital cost of the plant is $600 million and it operates for 40 years with a capacity factor of 95%. What is the contribution of CAPEX to LCOE? Given the difference you (hopefully) find, what contributes the remaining costs?
Installed capacity of the plant 200 MW
Capital cost = Rs 400 crores
Rate of interest and depreciation= 12%
Annual cost of fuel, salaries and taxation = Rs 5 crores
Load factor = 50%
Also estimate the saving in cost per kWh if the annual load factor is raised to
60%.

- The demand for electric power is usually much higher during the day than it is at night, and utility companies often sell power at night at much lower prices to encourage consumers to use the available power generation capacity and to avoid building new expensive power plants that will be used only a short time during peak periods. Utilities are also willing to purchase power produced during the day from private parties at a high price. Suppose a utility company is selling electric power for $0.06/kWh at night and is willing to pay $0.13/kWh for power produced during the day. To take advantage of this opportunity, an entrepreneur is considering building a large reservoir 50 m above the lake level, pumping water from the lake to the reservoir at night using cheap power, and letting the water flow from the reservoir back to the lake during the day, producing power as the pump–motor operates as a turbine–generator during reverse flow. Preliminary analysis shows that a water flow rate of 2…arrow_forward2. Consider the system described in the news: at night, when there is energy left, water is pumped from a large lake to a reservoir at 80 m above the lake level. During the day, this water is used to generate energy in a turbine located 80 m below the elevated reservoir. Considering that the water flow is always 5000 liters/s (both at the inlet of the reservoir and at the outlet) and that the pump and turbine efficiencies are 70%, what is the power (in kW) required by the pump and the power (in kW) recovered in the turbine.

- Problem 10 A homeowner is trying to decide between a high-efficiency natural gas furnace with an efficiency of 95 percent and a ground-source heat pump with a COP of 3.3. The unit costs of electricity and natural gas are $0.112/kWh and $1.44/therm (1 therm = 105, 500 kJ). Determine which system will have a lower energy cost.arrow_forwardSix years ago, an 80-kW diesel-electric set cost $145,000. The cost index for this class of equipment six years ago was 187 and is now 194. The plant engineering staff was considering a 120-kW unit of the same general design to power a small isolated plant that would have cost $200,145. Based on the information above the plant engineering staff is considering a 100-kW unit of the same general design to power a small isolated plant. Assume we want to add a pre-compressor, which (when isolated and estimated separately) currently costs $10,000. Determine the total cost of the 100-kW unit.arrow_forwardI need helparrow_forward
