In this article, the investment cost of an energy storage system that can be put into commercial use is composed of the power component investment cost, energy storage media investment cost, EPC cost, and BOP cost. The cost of the investment is calculated by the following equation: (1) CAPEX = C P × Cap + C E × Cap × Dur + C EPC + C BOP
It involves dividing all expenses (including capital expenditures and operation and maintenance costs throughout the system's lifetime N) by the amount of energy discharged by the storage system, Eout, over the same period. The capital cost and energy output are adjusted for the time value of money using the discount rate.
By means of technical economics, the potential value and development prospects of energy storage technologies can be revealed from the perspective of investors or decision-makers to better facilitate the deployment and progress of energy storage technologies.
The lifecycle cost of an ESS are divided into four main categories: Upfront Owners Costs; Turnkey Installation Costs (energy storage system, grid integration equipment, and EPC); Operations and Maintenance Costs; and Decommissioning Costs . The table here further segments costs into subcategories and shows items included in this study.
Energy storage technology is a crucial means of addressing the increasing demand for flexibility and renewable energy consumption capacity in power systems. This article evaluates the economic performance of China's energy storage technology in the present and near future by analyzing technical and economic data using the levelized cost method.
From 8 h to 16 h, the LCOE of thermal storage is under 0.5 CNY/kWh, making it economically competitive. The LCOS of lithium batteries and thermal energy storage overlap when the duration is between 2 and 4 h, and the economic advantage of thermal energy storage gradually exceeds that of lithium batteries.
