As one of the world’s leading financial institutions, Banco Santander serves millions of customers across more than 150 countries. In the financial sector, every second counts, making a secure and uninterrupted power supply essential. Since 2012, a state-of-the-art Piller UPS system has ensured maximum stability and reliability at the bank’s data center in Solares, near its corporate headquarters in Spain.
The original installation included 8 UNIBLOCK™ UBTD units with flywheel technology and external diesel generators in an isolated-parallel (IP) configuration. With a total capacity of 17.2 MVA, this system has provided uninterrupted, high-performance power for over a decade – even under the most demanding conditions.
Now, Banco Santander is once again investing in Piller’s proven technology to meet the growing demands of its expanding digital infrastructure. The system is being doubled with an additional 8 UNIBLOCK™ UBTD units, bringing the total capacity to 34.4 MVA. This expansion guarantees seamless performance, future-proof reliability, and continuous power availability for the bank’s critical operations.
Unique IP-Bus System for Maximum Efficiency and Security
Piller’s isolated-parallel (IP) system uniquely combines the benefits of both isolated-redundant and parallel-redundant UPS configurations. This approach enhances fault tolerance, optimizes maintenance efficiency, and significantly reduces redundant UPS units – eliminating the need for standby operation. As a result, Banco Santander benefits from a system that maximizes resilience, minimizes energy consumption, and reduces operational costs.
