This paper draws on the whole life cycle cost theory to establish the total cost of electrochemical energy storage, including investment and construction costs, annual operation and maintenance costs, and battery wear and tear costs as follows: $$ LCC = C_ {in} + C_ {op} + C_ {loss} $$. (1)
The total cost of thermocline storage system can be expressed as the summation of storage material cost (HTF and PCM), container cost, encapsulation cost, and overhead cost.

The levelised cost approaches for energy storage include metrics such as the levelised cost of storage when electricity is discharged
Overall the AC-Load topology has the lowest cost-per-kWh. As explained in Section 2.2, DC loads often start with fewer power conversion stages, and so the incremental cost of adding storage to DC loads appears higher. Both the AC-Load and DC-Load topologies cost less per kWh than centralized storage.
