In this context, power electronics plays a strategic role. At ZGR Corporación, we are at the forefront with solutions that guarantee a secure, efficient, and sustainable power supply with high power quality—helping data centers optimize energy consumption, improve reliability, and reduce costs.
A booming market: the big numbers behind data centers
The data center sector is expanding at an unprecedented pace. According to Statista Market Insights, the global market is expected to reach USD 438 billion by 2028, with an annual growth rate of 6.5%. The rise of AI and increasing demand for processing capacity are accelerating this trend.
Spain, in particular, is one of the European countries leading data center deployment. Installed capacity will increase from 160 MW to 600 MW by 2026, according to Spain DC.
En este contexto, las inversiones en estas infraestructuras están alcanzando cifras récord:
Record investments highlight this momentum:
- Google has allocated USD 13 billion to new data centers in the U.S.
- Amazon Web Services (AWS) announced USD 35 billion in Virginia for new data center infrastructure.
- Microsoft is investing USD 1 billion per month in data centers.
Meanwhile, technological transformations are reshaping the landscape, with data centers at the core:
- 5G and IoT: more connected devices demand greater processing and storage capacity.
- Smart cities: robust and efficient digital infrastructures are essential.
- Metaverse and Generative AI: applications requiring massive energy consumption and real-time processing.
Such growth is not sustainable without advanced energy management. This is where ZGR Corporación makes the difference, with power electronics solutions tailored to sector challenges.
Reliability and power quality: industrial UPS, DVRs, and SEPEC
Data centers require an uninterrupted, high-quality power supply. Any outage or fluctuation can trigger multimillion-dollar losses and service downtime.
ZGR’s industrial and modular UPS systems offer high reliability and 24/7 availability, with efficiencies above 98%. Compact and robust, they provide scalable and flexible architectures that adapt to the evolving needs of a data center without oversizing the initial investment. They also include advanced monitoring and real-time management.
Within industrial UPS solutions, SEPEC systems deserve special mention. These units are ideal for facilities with on-site generators requiring precise voltage control and system stability. Many data centers operate with their own backup generators to ensure continuous power supply, especially in areas with unstable grids or for critical processes that cannot tolerate interruptions.
This capability to ride through interruptions is arguably SEPEC’s most valuable differentiator versus DVRs.
ZGR SEPEC systems are modular (from 200 kVA to 800 MVA) with a line voltage rating of 400 V. They offer a minimum of 5 minutes of autonomy at rated power, expandable through integration with diesel gensets. They also support seamless transfers between sources with no impact on loads, while enabling bidirectional current flow.
DVRs: the battery-free solution
Another key technology gaining traction among data center operators is the DVR (Dynamic Voltage Restorer). These power electronics devices are designed to protect critical loads from issues such as voltage deviations (over/undervoltage), voltage sags (dips), fluctuations, and flicker.
ZGR DVRs are modular (from 150 kVA to 6 MVA) and cover a wide line voltage range (200 V to 34.5 kV). Their main advantage: they operate without batteries, delivering continuous in-range voltage regulation. This translates into minimal maintenance requirements and highly competitive operating costs. They restore voltage during three-phase sags up to 60% depth and support bidirectional current flow.
In combination with ZGR UPS systems, DVRs ensure a robust, stable, and secure power supply—protecting data center infrastructure from any grid anomaly.
Efficient distribution: 30 years of expertise applied to data centers
Reliable and efficient power distribution is fundamental to data center performance. With more than 30 years of experience in electrical networks, transmission, and power distribution, ZGR applies its expertise to deliver dedicated solutions for this sector.
We have developed proprietary switched-mode rectifiers/chargers, such as the new TPS 500, which optimize energy conversion. In general, high-voltage DC distribution architectures are increasingly required within data centers.
Clean energy for sustainable data centers: central inverters and BESS
Data centers are under increasing pressure to reduce their carbon footprint, integrating renewable energy sources—particularly on-site self-consumption from photovoltaic plants. To achieve this, advanced conversion systems are essential to optimize energy usage.
In this field, ZGR’s central inverters CTR 3000 and upcoming CTR 4500 are specifically designed for large-scale installations. These are high-power units engineered to operate under extreme conditions: robust, flexible, and highly productive.
One of their greatest innovations lies in the cooling system. Unlike liquid cooling solutions, ZGR has developed an industrial-grade air-cooling system offering:
- Greater equipment durability.
- Lower operating costs and simpler maintenance.
- Higher reliability and reduced risk of catastrophic failures.
- Higher energy efficiency.
Energy storage: the key to sustainable data centers
The future of data centers and industrial self-consumption systems depends on advanced energy storage to reduce grid dependency, maximize renewable integration, and guarantee stable supply at all times.
Imagine combining Battery Energy Storage Systems (BESS) with renewable generation plants—whether solar or wind. The result: improved grid stability through regulation services and synthetic inertia at the point of connection.
ZGR’s bidirectional chargers PCS 3000 and PCS 4500 store energy when demand is low and release it when needed, optimizing consumption and operational efficiency.
A future of opportunities for data centers and power electronics
Generative AI is driving data centers’ energy consumption to new heights. According to Gartner, AI workloads will increase energy demand by 160%, and by 2027, 40% of AI-enabled data centers will be constrained by energy availability.
In this scenario, ZGR Corporación positions itself as a strategic partner, offering:
- Industrial and modular UPS, SEPEC, and DVRs to ensure service continuity.
- Switched-mode rectifiers/chargers, TPS units, and distribution systems for efficient energy management.
- Central inverters and BESS for enhanced sustainability.
- In-house technical services and comprehensive supply to maximize operational efficiency 365 days a year.
