The true cost of energy storage depends on the so-called LCOE = Round-trip efficiency + maintenance costs + useful life of the energy system
By Anna W. Aamone
“With regard to [battery] energy storage systems, many people erroneously think that the only cost they should consider is the initial – that is, the cost of generating electricity per kilowatt-hour. However, they are not aware of another very important factor.
This is the so-called LCOE, levelized cost of energy(also known as cost of electricity by source), which helps calculate the price of the electricity generated by a specific source. The LCOE also includes other costs associated with producing or storing that energy, such as maintenance and operating costs, residual value, the useful life of the system and the round-trip efficiency.
