This is not the first time we have collaborated with Afflelou on initiatives related to eye health. In 2023, we took a pioneering step by becoming the first company in Spain to join its Protect Plan. Thanks to this agreement, our employees were able to access eye examinations, glasses or contact lenses, as well as blue-light-filtering lenses to help prevent the eye strain associated with prolonged screen use.

With this new initiative, we are strengthening a partnership based on a shared objective: promoting people’s wellbeing through practical actions that help protect their health. On this occasion, our focus is on an exceptional event.

Backup Power for the Steel Industry: Maximum Reliability for Critical Processes

The continuity of the power supply is a key factor in industrial environments with continuous production processes and high energy demands.

In this context, Genesal Energy supplied a 1,250 kVA generator set to a steel manufacturing company in northern Spain, ensuring the operational continuity of its plant in the event of any disruption to the electrical grid.

A Demanding Environment Where Power Cannot Fail

Facilities of this kind require a constant electrical supply due to the uninterrupted nature of their processes and the high energy consumption of their equipment. An uncontrolled outage can result in anything from machinery damage to significant losses of in-process materials, while also compromising personnel safety.

In these environments, having a reliable backup power system is essential to keep critical assets such as furnaces, hydraulic systems, cranes and control equipment operational. Furthermore, sudden temperature fluctuations caused by an unexpected shutdown can severely affect the entire infrastructure, leading to substantial financial losses.

Continuity, Autonomy and Adaptability: The Engineering Challenge

The client required a solution capable of ensuring the continuous operation of critical systems, minimising risks while guaranteeing both plant safety and compliance with stringent operational requirements.

Genesal Energy’s engineering team designed a bespoke solution based on a generator set mounted on a 4,400mm base frame, featuring an engine-alternator assembly with a flexible direct coupling.

Unlike other configurations, the system did not incorporate an integrated fuel tank. Instead, it is fed from a certified 1,000-litre double-wall fuel tank complemented by an additional 1,500-litre tank equipped with a fuel transfer system and pumping panel, ensuring the autonomy required for continuous operation.

Advanced Safety and Total Control

One of the key aspects of the project was the incorporation of advanced safety features which are less commonly found in this type of application, including a lockable battery compartment with a padlock-operated isolator switch and a 2,000A motorised circuit breaker, also fitted with a locking system.

The control panel was fully customised to the client’s requirements, incorporating specific alarms, colour-coded wiring identification, and an audible and visual signalling tower to indicate the operating status of the generator set. Attention was also given to operational safety through the inclusion of guards on moving and hot components, as well as emergency stop systems.

Seamless Integration into the Facility

The project also included the design of the auxiliary systems required to ensure the correct integration of the generator set within the plant. Specific calculations were carried out for exhaust gas evacuation, leading to the supply of a double-wall stainless-steel modular chimney system.

In addition, components such as a discharge plenum, flexible connector and louvre grille were designed and installed to channel radiator airflow to the outside, optimising system performance and ensuring safe operating conditions.

The logistics centre’s plant room had significant space constraints, making the installation design one of the main challenges of the project.

To address this limitation, we developed a 1,850 kVA open generator set mounted on a fully bespoke base frame, designed to fit the available space without the need to dismantle any components during transport. This solution simplified both logistics and installation work.

The base frame incorporates a 1,000-litre fuel tank that provides the autonomy required for this application. The power and control panels were also integrated into the base frame, making optimum use of the available space while maintaining full accessibility for maintenance work.

Complete integration: from the generator set to the building

Our involvement went beyond supplying the generator set, as we also developed the complete installation engineering.

We designed the exhaust gas system and collaborated on defining the acoustic attenuation solution. As part of this work, our technical team designed the ventilation attenuators, which were subsequently manufactured by the customer.

Before delivery, the generator set underwent the corresponding FATs (Factory Acceptance Tests) at our facilities, attended by both our direct customer and the end customer. During the tests, single-step load impacts of up to 65% were applied to verify the generator set’s correct performance and its response capability under the installation’s operating requirements.

“Essential reliability”: our way of understanding backup energy in the healthcare sector

cratividad de la campaña de sanidad y centros salud de Genesal Energy

The energy supply is one of those elements that rarely becomes the centre of attention… until it is no longer available. In the healthcare sector, however, that possibility is simply not part of the equation. Hospitals, clinics and medical centres depend on a continuous power supply to guarantee something far more important than their own operations: patient safety and the continuity of healthcare activity in situations where every second has a real impact.

At Genesal Energy, we understand this reality through the responsibility that comes with working for critical infrastructures, which is why we place reliability at the heart of everything we do.
We speak of “essential reliability” because we believe that backup power cannot be regarded as a complementary or secondary system within a hospital. In reality, it is a structural component that supports the operation of key areas and must respond immediately and without margin for error in the event of any incident. This approach leads us to design solutions that, in addition to meeting technical requirements, are intended to integrate naturally into environments where demands are at their highest and tolerance for failure is non-existent.

Designed with every second in mind

Our way of addressing this challenge begins with bespoke engineering. Every healthcare infrastructure has its own characteristics, from its electrical configuration to the type of activity it carries out, and this requires a specific response for each project. That is why we develop and manufacture energy solutions capable of adapting to complex architectures and guaranteeing supply to especially sensitive areas such as operating theatres, intensive care units, laboratories and diagnostic systems. It is not simply about ensuring that a system works, but about ensuring that it does so with the precision and reliability required in an environment where any interruption may have critical consequences.

Preparation, response and integration

In this context, the ability to anticipate and respond is essential. Our solutions incorporate automatic start-up systems in the event of mains failure, redundant configurations that ensure permanent availability, and monitoring tools that enable continuous supervision of the installation status. All of this is combined with a design approach focused on integration within the hospital environment, where aspects such as sound attenuation play an important role in ensuring that the technology coexists with healthcare activity without causing disruption.

Hospitals, clinics and medical centres depend on a continuous power supply to guarantee something far more important than their own operations: patient safety and the continuity of healthcare activity in situations where every second has a real impact.

At the same time, we understand that the future of the healthcare sector also involves moving towards more efficient and sustainable models. That is why we incorporate ecodesign criteria into the development of our equipment, applying methodologies certified under ISO 14006 that allow us to reduce environmental impact from the design phase onwards while covering the entire product life cycle. This approach enables us to respond to the sector’s growing sustainability requirements without ever compromising the reliability or availability of the power supply.

A vision built on real experience

Our understanding of energy within the healthcare sector is shaped by the experience accumulated through projects developed across different countries and contexts. In this regard, we have worked with hospitals and healthcare centres in Spain, the United Kingdom and Germany within Europe, as well as in Bolivia and Ecuador in Latin America, and in the Caribbean, specifically in Trinidad and Tobago.
This accumulated expertise allows us to continue refining our solutions with one clear and constant objective: to always be ready to respond when it truly matters.
