Battery Energy Storage Systems (BESS) in solar power plants will shape the future of technology. Because new battery types, artificial intelligence integration and hybrid systems increase the performance, efficiency and sustainability of BESS. While existing standards such as IEC 62933-2-1 support these developments, industry trends are pushing the boundaries of energy storage. In this article, we will discuss the innovations in BESS technology and the future direction of integration with solar energy, even though there is no licensed power plant installed in Turkey yet (April 2025).
Next Generation Battery Technologies
Solid State and Flow Batteries
While Lithium Iron Phosphate (LFP) batteries are currently widespread, solid-state batteries and flow batteries look set to be the talk of the future. Solid-state batteries offer higher energy density and safety by using a solid material instead of a liquid electrolyte, and more easily pass the thermal runaway tests of IEC 62619. These technologies promise longer-lasting and flexible storage solutions for solar power plants.
Optimization with Artificial Intelligence
Evolution of EMS and BMS
Artificial intelligence (AI) is transforming BESS’ Energy Management System (EMS) and Battery Management System (BMS). The performance parameters of IEC 62933-2-1 (e.g. round-trip efficiency of 98%) can be optimized in real time with AI. For example, in a power plant, AI-powered EMS can make energy distribution 10% more efficient by predicting peak demand hours. This means both cost savings and grid stability. In fact, we can say that technology and software will be the other business line that will drive the development of storage systems.
In the future, the BESS is expected to work with hybrid systems, rather than on its own. Excess electricity generated by solar power can be converted into hydrogen (H2) and stored, ideal for long-term energy storage. While the environmental guidelines of IEC TS 62933-4-1 accommodate the low-carbon production of hydrogen, a 10 MW system in the Technical Specification can be expanded with a hybrid approach. For example, short-term storage with BESS during the daytime, while excess energy can be converted to hydrogen and stored for weeks. This offers a solution to the seasonal fluctuations of solar energy.
Global Trends and Forecasts
Capacity Expansion and Innovations
The energy storage market is growing rapidly; the International Renewable Energy Agency (IRENA) estimates that global BESS capacity will double by 2030. This growth is supported by the commercialization of new technologies. For example, solid-state batteries are expected to enter mass production in 2025, or AI-based systems will become widespread. With these trends, solar power plants will become more reliable and scalable.
Future Vision and Conclusion
The future of BESS focuses on maximizing the potential of solar energy through technological innovation. Solid state batteries, AI optimization and hybrid systems are ushering in a new era of energy storage. IEC standards drive these developments, while documents such as the Technical Specification lay the groundwork for practical applications. Energy storage will be a critical issue in the future.
