Battery type Segment Analysis

The battery type segment is divided into lithium-ion batteries, lead-acid batteries, flow batteries, sodium-sulphur batteries and others. The lithium-ion batteries segment dominated the market, with a market share of around 44% in 2024. Lithium-ion batteries have taken leadership in the global Battery Energy Storage Systems (BESS) market with the highest share of the market in terms of the scale of energy in the utility scale and behind-the-meter markets. It is mainly predisposed to this dominance by their favourable performance features such as high energy density, lightweight, long cycle life, and high charge rates. The characteristics of lithium-ion batteries render them exceedingly suitable to an expansive variety of applications, such as grid parametrization and renewable energy integration, or residential backup power and electric vehicle (EV) subsistence systems. Of all battery chemistries, lithium-ion is the most cost-effective one in terms of efficiency and scalability, and that has made the battery chemistry popular. The second reason as to why they are dominating is the swift reduction in lithium-ion technology, as it is mainly due to the economies of scale through mass production brought by the manufacturers of EVs. The further improvements made on the safety, reliability and lifecycle of the lithium-ion batteries can be attributed to technological developments and the innovation on work front in battery management systems (BMS), thermal control and energy efficiency. Besides, lithium-ion batteries require less effort when it comes to procurement and implementation due to the global supply chain that was built, high availability, and robust R&D base in support of the battery chemistry. More so, lithium-ion batteries also have a compact form factor with modularity that will enable flexible system design and installation even within space-limited facility spaces.

Connection type Segment Analysis

The connection type segment is divided into on-grid and off-grid. The on-grid segment dominated the market, with a market share of around 62% in 2024. The on-grid unit controls the overall market of Battery Energy Storage Systems (BESS) in the world because it is of paramount importance in terms of assisting the modern power grid to work and meeting the needs of having integrations of renewable energy resources. On-grid, or grid-connected BESS, refers to systems that are directly connected to the main electricity grid, where either excess energy can be pushed onto the grid according to demand or the desired energy can be pulled-off the grid in order to charge the power system. The advantage of this architecture is that the benefit is notable in utility-scale applications, where the storage is applied in stabilizing the voltage, peak loading, and maintenance of constant and balanced power delivery in response to variability in renewable energy generation caused by solar and wind energy supply. The world-changing dynamic toward the modernization and decarbonization of grid is one of the basic forces that made this segment dominant. Additionally, the on-grid BESS projects are more likely to receive regulatory support and government financing, especially in territories, such as Asia-Pacific, North America, and Europe, where there are already significant plans on the adopted energy transformation. Such scalability, that is achieved in on-grid storage systems, as well as their centralized control and economic benefits contribute to a broad implementation of those systems further. Consequently, on-grid BESS will continue to serve large-scale energy storage requirements, and thus they will continue to dominate the market in the world.

Energy capacity Segment Analysis

The energy capacity segment is divided into above 500 MW, 100–500 MW and below 100 MW. The above 500 MW segment dominated the market, with a share of around 39% in 2024. Such large capacity systems are mostly used in utility-scale projects, where the capacity to store and launch large quantities of electricity are essential in managing the supply and demand span across vast geographical locations. As renewable sources such as solar and wind generation become more pervasive, but by their nature intermittent, grid operators can rely on large-capacity BESS to store the excess generation and draw upon it during times of peak demand and is, therefore, a source of a stable and consistent power source. The scale of operation also enhances the competitiveness of this segment since big installations generally offer better cost per megawatt-hour, better system efficiency and standardization, and better cost to maintain and operate. Moreover, the rapid development of batteries chemistries and system integration has shown it possible and cost effective to implement such massive storage hardware. The above 500 MWh segment is therefore the fastest growing segment and it is well placed as a keystone of the international energy transition and the grid architecture of the future.

The end-user segment is divided into utilities, commercial, residential and industrial. The utilities segment dominated the market, with a share of around 57% in 2024. Utilities play a key role in the running and management of electric distribution and transmission systems, which makes them the most natural owners and operators of large-scale energy storage systems. Utilities aim at using BESS to resolve some key challenges posed by the rising number of intermittent renewable energy sources such as wind and solar. Through the use of battery storage, utilities will be able to do away with the volatility of the supply, balance loads, and improve grid reliability to ensure a steady and smooth supply of power to the consumers. The capability to offer grid services, in the form of frequency regulation, voltage support, and peak load shaving defines BESS as essential to smooth up-to-date grid management. The other contribution to the supremacy of utilities is their ability to invest in high capital and big projects which at the initial stages of implementation need high levels of capital outlay thus creating long-term advantages in terms of operations. The utilities can access the finances, regulatory interests, and engineering skills to build and operate high-complexity BESS infrastructure unlike individual consumers or small commercial organizations. The utilities also enjoy the cost advantages of economy of scale, centralized control, and integration of energy capabilities to optimise towards large geographical regions and end-users. Besides, favourable government regulations and policies tend to favour utilities when it comes to energy storage deployment proposals in the form of subsidies, mandates, and other efforts related to market reconciliations aimed at speeding the shift to clean energy.
