Energy Storage
At VOERAL, we offer comprehensive solutions for energy storage, combining technical expertise, high-quality equipment, and professional consulting. Whether for large renewable energy plants or industrial and commercial facilities, we take care of the entire process — from supply and installation to data collection and validation.
BESS Systems
At VOERAL, we are committed to developing sustainable energy solutions. That’s why we offer high-capacity energy storage systems designed for industrial applications, renewable energy integration, and electrical grid support.
We have a collaboration agreement with TDG IBERNAVITAS, a company specialised in BESS (Battery Energy Storage Systems) featuring state-of-the-art technology and scalable solutions ranging from 232 kWh to several MWh. Through this partnership, we provide our clients with their full product range, fully adapted to the specific needs of each project.
In addition to equipment supply, VOERAL manages all installation, civil works, and commissioning tasks, offering a comprehensive turnkey service that guarantees efficiency, safety, and regulatory compliance. From foundation works and underground cable trenching to integration with photovoltaic or wind systems, we ensure a ready-to-operate installation.
Our experience in renewable energy and our strong technical capabilities allow us to undertake demanding projects with the reliability and agility our clients require.
Technological
Advantage
The advantages of our storage systems make a real technological difference compared to other equipment available on the market:
Modular and
scalable architecture
Systems such as ORION, ATLAS, and HELIOS are designed for easy parallel expansion, allowing capacity growth according to energy needs without interrupting operations.
High energy density
in a compact format
Optimised structure that reduces civil works costs and simplifies fast installation.
Advanced
liquid cooling
Maintains cell temperature variations within ≤ 3 °C, extending system lifespan and improving operational efficiency.
High safety
standards
LiFePO₄ batteries with IP55/IP67 protection, integrated fire suppression systems, and materials resistant to dust, humidity, and high temperatures.
Smart
operation
Remote control via EMS (Energy Management System) with online monitoring, automatic charge/discharge adjustment based on demand and energy tariffs.
Wide range of
energy applications
Adaptable to demand regulation, price arbitrage, photovoltaic integration, and industrial backup.
Reliability and
technical robustness
Each battery rack operates independently with a dedicated PCS, so a failure in one module does not affect the rest; additional racks can also be added after initial commissioning.
Bidirectional AC/DC
centralised control
Manages multiple converters from a unified system, improving energy efficiency and grid stability.
Transparent
economic performance
The EMS automatically calculates tariff benefits, carbon income, and energy savings, enabling informed decision-making
Extended
lifespan
Thanks to thermal stability and intelligent management, these systems are designed to exceed 8,000 cycles at 95 % DoD without significant degradation.
Large-scale plants
The energy storage systems offered by VOERAL are designed to integrate seamlessly into large renewable installations, industrial facilities, and critical electrical infrastructures.
Thanks to their modular and scalable architecture, they provide high-capacity solutions — from 3.7 MWh up to several hundred MWh — fully adaptable to the specific needs of each plant. The ATLAS and ORION models, available in containerised configurations, enable rapid, safe, and efficient deployment, reducing construction time and simplifying operation.
These systems help optimise photovoltaic or wind energy production, stabilise the grid, reduce demand peaks, and take advantage of intelligent price management. They also offer high operational reliability thanks to their liquid cooling system, precise thermal control, individual rack management, and real-time monitoring.
VOERAL manages both the supply of systems and the complete civil works and installation, delivering turnkey projects that meet the highest technical and regulatory standards.
