"""Calculate the Levelized Cost of Electricity (LCOE) using the
fixed-charge-rate method:
LCOE = ((fixed_charge_rate * capital_cost + fixed_operating_cost)
/ annual_energy_production + variable_operating_cost)
Parameters
----------
fixed_charge_rate : float | np.ndarray
Fixed charge rage (unitless)
capital_cost : float | np.ndarray
Capital cost (aka Capital Expenditures) ($)
fixed_operating_cost : float | np.ndarray
Fixed annual operating cost ($/year)
annual_energy_production : float | np.ndarray
Annual energy production (kWh for year)
(can be calculated as capacity * cf * 8760)
variable_operating_cost : float | np.ndarray
Variable operating cost ($/kWh)
Returns
-------
lcoe : float | np.ndarray
LCOE in $/MWh
