Simple Levelized Cost of Energy

LCOE is the cost of generating energy for a particular systemIt is the minimum price at which energy must be sold for an energy project to break even It includesinitial investment, operations and maintenance, cost of fuel, cost of capital.

calculationsLCOE = {(overnight capital cost * capital recovery factor + fixed O&M cost )/(8760 * capacity factor)} + (fuel cost * heat rate) + variable O&M cost.

Where capital recovery factor is the ratio of a constant annuity to the present value of receiving that annuity for a given length of time.

Using an interest rate i, the capital recovery factor is: CRF = {i(1 + i)^n} / {[(1 + i)^n]-1} where n is the number of annuities received.

capacity factor representing the portion of a year that the power plant is generating power.
