Utility Owned Segment Captured Largest Share in Solar BESS Market

Utility-owned solar energy storage batteries are energy storage systems that utility companies own and operate. These batteries are typically used to store excess energy generated by utility-scale solar power plants. The stored energy can then be discharged during periods of high demand or low solar energy production to stabilize the grid and enhance overall system reliability.

The advantages of utility-owned solar energy storage batteries for businesses include their ability to stabilize the grid, improve reliability, and manage peak demand effectively. By storing excess solar energy, these batteries help balance supply and demand, reducing the risk of outages and enhancing the overall stability of the electricity grid. Additionally, they can help businesses reduce their electricity costs by discharging stored energy during times of high demand, reducing peak demand charges. Moreover, these batteries enable better integration of renewable energy sources into the grid, supporting businesses in their sustainability goals.

On Grid Segment Held the Major Share in Solar BESS Market

An on-grid solar battery system is a solar energy setup connected to the main electricity grid. It includes solar panels, inverters, and a battery bank for energy storage. During the day, the solar panels generate electricity, which can be used to power the home or business. Any excess electricity produced can be stored in the battery bank or fed back into the grid for credit. At night or when solar energy production is low, electricity can be drawn from the grid or the battery bank.

Key players in the market are partnering to develop solar energy and energy storage solutions. In February 2024, Å Entelios, a Norway-based electricity company announced its partnership with Solar Power Accelerator, a Sweden-based solar power solutions company to offer energy as a service (EaaS). EaaS presents a comprehensive suite of services designed for commercial and industrial real estate owners and industries. This system provides grid support by reducing peak demand and stabilizing grid voltage, as well as backup power during grid outages, ensuring uninterrupted operations for users.

Large Scale (>1MW) Segment to Drive the Solar BESS Market

Large-scale solar energy storage systems are energy storage solutions with a capacity exceeding 1 megawatt (MW). These systems are engineered to store surplus energy produced by large solar power plants, ensuring grid stability and enhancing overall system dependability. Large-scale solar BESS is integrated with utility-scale solar installations. These solar BESS optimize energy utilization and provide a reliable power source even during periods of low solar energy production.

Large scale energy storage systems play a crucial role in balancing energy supply and demand by storing excess energy generated during sunny periods and releasing it as needed. Large-scale storage solutions facilitate the seamless integration of renewable energy sources, such as solar power, into the grid. This compensates for fluctuations and supports the transition from fossil fuels to cleaner energy sources. Strategically locating solar energy storage systems near demand centers reduces transmission losses, as energy does not have to travel long distances from remote solar farms to urban areas.

Industrial Applications Segment held the Largest Share in Solar BESS Market

Industrial application segment held largest market share due to use of solar BESS in various industrial process. Solar BESS is used in water desalination, enhanced oil recovery, food processing, chemical production, and mineral processing, among others. Solar energy applications are promising solution for meeting global electricity demands, especially with fossil fuels depleting and environmental concerns rising. Solar power, particularly through concentrating solar-thermal power (CSP) technology, offers a cost-effective and eco-friendly alternative. CSP systems use mirrors to concentrate sunlight onto receivers, generating electricity for various industrial applications. This versatile technology is revolutionizing the way to generate and utilize electricity.

The rising focus on clean energy generation is driving the demand for solar energy in industrial sector. For instance, in July 2023, according to International Energy Agency, a France-based government organization in energy sector, published a report on solar PV generation. According to report, in 2022, solar photovoltaic (PV) generation saw a remarkable increase of 270 terawatt-hours (TWh), marking a 26% growth and reaching nearly 1,300 TWh. This growth represents the largest absolute increase in generation among all renewable technologies in 2022, surpassing wind power.
