BESS: Better efficiency, stronger stability 

Battery Energy Storage Systems (BESS) have evolved beyond backup solutions to become strategic assets in the global shift toward cleaner energy. In today’s landscape, BESS gives companies a powerful edge, allowing them to turn energy market shifts into competitive gains while boosting operational resilience.

Storing energy for brighter returns

With these systems, companies can capture energy at peak production times and use it when grid prices surge. Without this capacity, any grid-drawn energy – including net-metered – carries additional costs: taxes, surcharges, and transmission fees that often total over half of an energy bill. Storage provides a way to avoid these expenses, making each stored kWh a financially strategic asset and accelerating return on investment.

The ability to adapt energy use to real-time needs while avoiding costly supply interruptions means BESS brings both efficiency and equipment protection. For companies aiming to thrive in fluctuating markets, energy storage has become essential for securing stability and reducing financial volatility.

The BESS advantage

  1. Versatile applications – Modern energy storage systems adapt seamlessly to a wide range of industries and operational demands, from construction sites and mining to telecommunications and large-scale events. Compact and easy to transport, these systems provide reliable power even in remote locations, reducing dependence on fossil-fuel generators. Battery storage offers a stable and dependable energy source, helping companies keep equipment operational while reducing their carbon footprint.
  1. Intelligent load management to balance and save – For businesses facing fluctuating energy demands, such as manufacturing, logistics, or data centers, energy storage provides a practical solution. Using features like “peak shaving” and energy arbitrage, these systems enable companies to optimize energy use. Instead of purchasing power at high rates during peak demand, companies can store it when prices are low and use it later. This approach cuts operating costs, stabilizes energy budgets, and supports better financial planning.
  1. Incentives fueling BESS adoption – Though recent changes have lifted the legal requirement for energy storage for prosumers, various financing programs still encourage BESS adoption. The “Casa Verde” program, for example, offers financial support for the residential sector, while European and government funds provide significant incentives for businesses investing in these technologies. These programs help companies reduce both installation and long-term costs, making them more competitive and supporting sustainable energy use.

Best practices for effective energy storage performance

Successfully implementing BESS requires more than installation; optimized configuration and rigorous maintenance are key to maximizing benefits.

Comprehensive consumption analysis and optimal storage sizing
Before implementation, a detailed assessment of energy consumption and production patterns helps tailor storage capacity to a company’s specific needs. Integrating an Energy Management System (EMS) adds value by providing an overview of energy flows, maximizing return on investment.

Proper system installation
For long-term performance, installations should be set up in controlled environments to prevent overheating and ensure durability. Maintaining stable temperatures and protecting against climate variations are essential for preserving battery life, especially for Li-ion batteries, which are more sensitive to fluctuations. These measures lower maintenance costs and reduce the risk of early degradation.

Active monitoring and preventive maintenance
Real-time monitoring helps ensure smooth operation and quickly addresses potential issues. Advanced monitoring systems provide early warnings of possible malfunctions, allowing maintenance teams to respond promptly. Preventive maintenance, supported by certified providers and regular updates to key components, ensures system stability and minimizes unexpected expenses.

Adhering to safety standards
To avoid incidents, energy storage installations must comply with safety standards and include protective devices. Periodic maintenance and working with authorized professionals are very important for safe and reliable operation.

Germany and Italy as European BESS front-runners

Germany and Italy are at the forefront of the European BESS market, driven by innovative programs and growing demand in both residential and business sectors.

Germany, powering growth through storage
In 2023, Germany added an impressive 5.9 GWh of battery energy storage capacity, with 87% of installations in homes. The commercial and industrial (C&I) sector saw 151% growth from the previous year, bringing cumulative capacity to 900 MWh. This reflects a strong shift toward storage as companies look to ease grid dependency and cut operational costs.

Italy, going all-in on sustainable upgrades
Italy’s Superbonus program, with its 110% incentive for eco-friendly renovations, spurred the installation of 3.7 GWh of battery storage systems last year. C&I companies increased their storage capacity to 410 MWh, enhancing their energy management strategies and reducing grid-related costs.

Stored energy, the backbone of Europe’s energy security and stability

Energy storage technologies and electrification play a key role in Europe’s energy stability and security, especially as renewable energy demand rises. Green sources currently supply 44% of the EU’s power grid, with electric consumption models nearing 23%. To effectively integrate renewable sources and maintain grid balance, flexible and resilient infrastructure solutions are essential.

Battery-based storage systems are critical in this context, supporting solar and other variable energy sources. Batteries can be deployed on a large scale within the power grid or individually for homes and businesses. Additionally, electrification in transport and heating adds further flexibility. Electric vehicles, for example, can function as mobile batteries, adjusting consumption based on system needs.

In 2023, Europe’s energy storage market hit a new milestone, adding approximately 17 GWh of capacity – a significant 94% increase over the previous year. This growth reflects a rising interest in Europe’s energy flexibility and the need for renewable integration. However, compared to other regions, Europe’s growth rate remains modest: China, for instance, installed around 60 GWh that same year.According to SolarPower Europe, the European Union will need 200 GW of storage capacity by 2030 to meet its flexibility goals, accounting for about 24% of annual electricity demand, as estimated by the European Commission. This capacity is crucial for supporting accelerated electrification and increasing the share of renewables in the energy mix.

The market structure is also expected to evolve: utility-scale storage and C&I solutions will grow significantly, while residential systems, though still important, will see a decrease in share. With digitalization and advanced technology implementation, the European storage market will be better positioned to meet future challenges.
