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%. calculate the cost of generation per kwh for a power station.

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…
