What cost gives the real and the true cost of 1 kwh delivred by hybrid renewable energy sources, is it the net present cost (NPC), or the levelized cost of energy (LCOE)?
The levelized cost of energy (LCOE) takes takes into consideration the plant capital investment, O&M cost, and the capacity factor of the plant. Hence, it is a good actual measure of the cost of electricity generation.
The net present cost brings in the time value of money which could be easily addressed when you calculate the LCOE.
Generally, it is necessary to state which types of RE resources you want to hybridize .For example Wind with solar or to add furthermore fuel cell or other possible RE resources. With compliments
