HOME / how much is the electricity price of an independent energy
The average price of lithium-ion battery packs is $152/kWh, reflecting a 7% increase since 2021. Energy storage system costs for four-hour duration systems exceed $300/kWh for the first time since 2017. Rising raw material prices, particularly for lithium and nickel, contribute to increased energy storage costs.
As we look ahead to 2024, energy storage system (ESS) costs are expected to undergo significant changes. Currently, the average cost remains above $300/kWh for four-hour duration systems, primarily due to rising raw material prices since 2017.
Battery cost projections for 4-hour lithium-ion systems, with values relative to 2024. The high, mid, and low cost projections developed in this work are shown as bold lines. Published projections are shown as gray lines. Figure values are included in the Appendix.
Battery storage prices have gone down a lot since 2010. In 2025, they are about $200–$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs. China's average is $101 per kWh. The US average is $236 per kWh. Knowing the price of energy storage systems helps people plan for steady power.

In September 2024, the average wholesale electricity price in Serbia decreased to 107 euros per megawatt-hour from 127 euros per megawatt-hour the previous month.
Hydroelectric power also constitutes a vital part of Serbia's energy portfolio. The Danube and other rivers offer substantial potential for hydroelectric generation, making it a key renewable energy source within the country's electricity mix.
Kolubara (Lazarevac) – coal mining basin. Energy mix 2.1.2 The amount of electricity generated in Serbia totals 7,120MW. This generation comes primarily from the eight lignite-fuelled thermal generating stations with an installed power of 3,936MW (two of these are located in Kosovo) and 9 hydro plants (a total installed power of 2,831MW).
1.1.2 The electricity market in Serbia is still dominated by state-owned public companies and is mainly characterised by the lack of full liberalisation, as well as the absence of significant participation by private companies. Furthermore, the existing infrastructure is generally old and outdated, thus vitally requiring modernisation.
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
As an emerging flexible resource in the power market, distributed energy storage systems (DESSs) play the dual roles of generation and consumption (Kalantar-Neyestanaki and Cherkaoui, 2021; Li et al., 2021), thereby complicating the market dynamics for energy storage users.
Other types of ESSs that are in various stages of research, development, and commercialization include capacitors and super-conducting magnetic storage. Hydrogen, when produced by electrolysis and used to generate electricity, could be considered a form of energy storage for electricity generation.
The main difference between them is that the amount of energy discharged from battery storage for a given hour is limited by the maximum rate of discharge, but the limit for deferrable demand is given by: For example, when thermal storage is used to replace air-conditioning, the energy discharged cannot exceed the amount of cooling needed.
