Typically, these costs are expressed as a levelised annual cost, that is, they represent the amount that an investor would expect to pay annually for the entire operation of the energy storage system, including the repayment of the initial capital costs.
It includes the costs of the power conversion system (PCS), costs associated with energy consumption and purchase, acquisition costs, cost for storage units (CSU)—costs related to energy storage (components of EnWheel modules), installation and delivery of the ESS unit, or cost of balance of the plant—BOP.
Current scientific knowledge offers multiple ways to store energy, including electrochemical, electrical, magnetic, mechanical, and thermal systems. The mechanical approach, represented by flywheel energy storage systems (FESS), has been scientifically evaluated as one of the most progressive energy storage methods.
The selection of an appropriate type of energy storage system depends upon many parameters, and it is important to choose a system with an optimal cost-to-performance ratio that can meet the technical requirements of a specific task.
In the case of ESS, it is applied as a Levelized Cost of Electricity (LCOE) . The efficiency indicator (called the economic performance index of the system) is generally calculated as the ratio between the sum of the discounted costs incurred over the lifetime of the system to the sum of the discounted actual energy values delivered.
It is alo important to identify the aspects that influence the relevance of the results, including macroeconomic factors such as inflation trends, government regulation of the energy market, and future fiscal and monetary policies of individual countries. Currently, energy storage systems pose a challenge for researchers in developed countries.
