We designed an emergency solution that meets the highest environmental standards in Europe. See our latest Engineering feat in Belgium

/in , /by

Genesal Energy has successfully completed a project to guarantee emergency power supply for a combined cycle power plant — a critical infrastructure in the heart of Belgium.

These types of facilities must be equipped with emergency generators, as any brief power outage can compromise safety systems such as water cooling, fire suppression, lighting, and auxiliary systems that are essential for the plant’s proper operation.

To prevent the risks associated with grid failure, two soundproofed generator sets were designed in 40ft containers for medium-voltage generation, connected in parallel to each other and the grid. A third 20ft container serves as a high-tech electrical room housing the central control system and medium-voltage switchgear. The installation also includes auxiliary systems for heating, air conditioning, and exhaust gas post-treatment, along with specific thermal insulation to improve overall plant efficiency.

The combined cycle plant in Belgium now has a robust, efficient and environmentally friendly emergency power system.

Safety was paramount in the project. Fuel tank heaters with ATEX (Explosive Atmospheres) certification were installed to prevent any risk of explosion and to withstand extremely low temperatures. Additionally, the containers were fitted with liquid collection trays and leak detectors that activate immediately in case of a spill, effectively preventing environmental contamination.

The electrical system was designed for remote management. The electrical room container includes an advanced control panel that enables simultaneous operation of both generator sets. Medium-voltage grounding resistors, automatic circuit breaker cells and a common power output system were also installed, allowing either generator to be isolated as needed.

Meeting strict environmental standards

One of the biggest challenges of the project was meeting Belgium’s environmental regulations – among the strictest in Europe. Our engineering team developed an integrated solution that includes an advanced exhaust gas post-treatment system with DPF filters, SCR technology, and a mixing chamber for urea injection, guaranteeing ultra-low emissions and full compliance with the most demanding standards.

Continuing with this focus on sustainability, components were also installed to reduce the noise level to below 80 dB at 1 m. Motorised air louvers were also included to isolate the equipment from ambient conditions during periods of inactivity.

Strategic collaboration with Mitsubishi

Mitsubishi’s collaboration was key to ensuring the reliability and performance demanded by a project of this scale.

Mitsubishi’s team worked closely with Genesal Energy’s engineering departments throughout the design process, ensuring seamless technology integration. This cooperation was essential to achieve optimal performance in critical conditions while meeting the project’s demanding environmental and operational requirements — in line with Europe’s strictest standards for emissions, efficiency, and sustainability.

The digitalisation of energy systems has revolutionised the power generator sector. In this context, advances in remote monitoring and telemetry for power generators are redefining the way these units are managed, monitored and optimised. The ability to start a generator remotely, monitor its status in real time and anticipate faults adds a level of efficiency, safety and reliability that was unthinkable just a decade ago.

How Does Remote Start Work in a Generator?

Knowing how to start a generator remotely is no longer the preserve of specialist technicians. Today, thanks to connectivity and automation technologies, any authorised user can start a generator from a mobile phone, tablet or computer – safely and securely.

Remote starting is carried out via control systems connected through mobile networks or Ethernet. These platforms allow the generator to be activated without being physically present, which is particularly useful in remote locations, emergency backup systems, or sectors such as industry, healthcare and telecommunications.

Benefits of Remote Monitoring in Generator Management

Equipping a generator with a remote monitoring system brings numerous advantages:

  • 24/7 supervision: real-time information on operational status, fuel levels, temperature, oil pressure, and more.
  • Instant response: the system sends immediate alerts in the event of a fault, enabling rapid intervention.
  • Maintenance optimisation: collected data supports the scheduling of preventive maintenance tasks, reducing unexpected shutdowns and extending the equipment’s service life.
  • Cost reduction: fewer breakdowns and unnecessary site visits translate into optimised technical and financial resources.

Moreover, these systems are scalable and adaptable to any generator model, from portable units to large-scale industrial solutions.

Key Telemetry Technologies for Power Generators

Telemetry in power generators relies on sensors, controllers and communication modules that collect and transmit data to cloud platforms. Key technologies include:

  • PLCs and intelligent controllers: for collecting generator operational data.
  • Communication modules (GSM, 4G, LTE, Ethernet, Wi-Fi): which transmit data to control centres or mobile applications.
  • SCADA systems and IoT platforms: for visualising data, generating reports, and controlling equipment remotely, reducing the need for human intervention.
  • Cybersecurity protocols: with encrypted communication and advanced authentication to safeguard remote system access.

These technologies are custom-integrated based on the generator type, power output, intended use, system integration and environmental conditions.

Applications of Remote Monitoring Across Sectors

Remote monitoring and remote start systems for power generators are now used across many sectors:

  • Data centres: where uninterrupted power is critical and continuous monitoring is essential.
  • Hospitals: where emergency generators must always be available with no margin for error.
  • Construction and infrastructure projects: in areas without stable grid access.
  • Telecommunications: in repeater towers and remote stations where access is difficult and power surveillance is vital.
  • Agriculture and livestock farming: to run irrigation, ventilation or refrigeration systems in rural areas.

In all these sectors, the ability to start a generator remotely is a strategic solution to unexpected power issues.

Impact on Efficiency and Maintenance of Generators

Remote monitoring has transformed the concept of operational efficiency. Thanks to telemetry, it is now possible to:

  • Reduce downtime.
  • Detect faults before they occur.
  • Improve the planning of technical resources.
  • Avoid unnecessary technician site visits.

In addition, the continuous collection of data enables predictive maintenance models, where systems “learn” from previous patterns to recommend specific interventions.

Advances in remote monitoring and telemetry for power generators are redefining the way these units are managed, monitored and optimised.

This approach not only improves the overall performance of the power generator but also enhances the reliability of the energy system as a whole.

Safety and Control in Remote Operation

One of the most valued aspects of remote start systems is security. To protect generator operation and prevent unauthorised access, various measures are implemented:

  • User profiles with differentiated permissions.
  • Access control using two-factor authentication.
  • Encrypted data transmission systems.
  • Operation logs for audits and traceability.

Furthermore, in the event of a fault or tampering attempt, the system can automatically block access and notify technical staff.

Trends and the Future of Smart Monitoring in Generators

The future of smart generator monitoring lies in even deeper integration with emerging technologies such as artificial intelligence and machine learning. These tools will enable:

  • The analysis of large volumes of operational data.
  • The early detection of anomalies, even before they become noticeable.
  • Greater automation of real-time energy management.

Likewise, the adoption of generators compatible with HVO (Hydrotreated Vegetable Oil) and other clean energy sources will require more advanced monitoring platforms that track not only performance but also the environmental impact of each operation.

Conclusion

The implementation of remote monitoring and telemetry is raising the bar for reliability, efficiency and control in the power generation sector. Being able to start a generator from anywhere, anticipate faults, and manage maintenance efficiently makes these systems essential allies in the transition towards a smarter, more resilient energy model.

The Importance of Generator Maintenance

/in /by

“Backup power isn’t a luxury – it’s a need. This blackout has shown us something essential: the importance of being prepared.”-Ángeles Santos, Director of HR and Institutional Relations at Genesal Energy

At 12:33pm CEST on the 28th of April, the Iberian Peninsula experienced an unprecedented event: a massive blackout that affected more than 55 million people. For hours, entire regions were left in the dark, with services interrupted and widespread uncertainty that exposed how vulnerable the power grid is to unexpected failures.

The consequences were immediate, impacting every sector of society: supermarkets closed, ATMs stopped working, traffic lights went out, telecommunications were disrupted, transport collapsed, petrol stations were out of service, industry ground to a halt – and the list goes on. The incident clearly demonstrated our deep dependence on a continuous and reliable power supply to keep daily life running.

And it’s not just about day-to-day activity; some sectors require an uninterrupted power supply under all circumstances. Hospitals, for example, rely on electricity to operate life-saving equipment like cardiac monitors and ventilators, and to carry out emergency procedures. Thanks to emergency generators, many of these facilities were able to continue operating normally.

Beyond the immediate impact, the blackout served as a stark reminder of the need for effective backup power solutions such as generator sets – and the need to guarantee their availability through proper maintenance. Being prepared isn’t just about having the equipment installed but ensuring it will respond when it’s needed most.

The Importance of Grid Security

The Iberian power system is made up of various energy generation plants (wind farms, solar parks, hydroelectric stations, combined cycle plants, etc.), which are interconnected by high-voltage transmission lines. These lines in turn connect to transformer substations, which lower the voltage from high to medium or low levels, before distributing electricity to points of use via medium and low-voltage networks.

Generator maintenance is essential in any sector that depends on these systems.

So, every time we switch on a light or plug in an appliance, we’re setting off a complex process that is constantly monitored to ensure energy generation matches demand – maintaining a fine balance between what’s produced and what’s consumed. However, the system is vulnerable: any failure can cause a power outage in a matter of seconds, as the recent blackout has shown.

That’s why many sectors – particularly those considered critical – must be equipped with backup power systems to guarantee supply continuity in the event of a grid failure:

  • In healthcare, a power outage can be life-threatening, as many patients rely on machines that must remain continuously powered. Emergency procedures cannot be delayed due to a lack of electricity.
  • In sectors such as data-centres and telecommunications, uninterrupted power is essential to maintain operations, prevent data loss and ensure emergency communication.
  • In industry, stopping production processes can cause damage to equipment, faults and major financial losses due to delays and downtime.

Ensuring an uninterrupted power supply – and with it, the safety of people and the resilience of industry – is not only a necessity, but a moral responsibility. In this context, emergency generator sets play a vital role as an alternative energy source.

How Do You Make Sure a Generator Responds When Needed?

It all starts with a proper installation and a configuration that allows for automatic response. A generator set includes key components like the engine, alternator and control panel. But its true value lies in its ability to activate without human intervention, thanks to the automatic transfer switch (ATS) – a device that detects a power cut, starts up the generator, and transfers the electrical load in a matter of seconds. This immediate reaction keeps power flowing during even the most critical moments.

But for this seamless response to work, one element is just as important as the system design itself: maintenance.

The Value of Maintenance: Ready for the Unexpected

Generator maintenance is essential in any sector that depends on these systems. It helps detect wear and tear, prevent unexpected breakdowns, and correct minor faults before they escalate and compromise system performance.

These tasks cover both the mechanical and electrical components and are carried out with the generator both stopped and running. Checks include:

  • Electrical, hydraulic and pneumatic connections
  • Fuel system (pump, filters)
  • Lubrication system (oil level and replacement, filters)
  • Cooling system (coolant level and condition, radiator cleaning)
  • Battery condition (charge level, electrolyte levels, terminal cleaning)
  • Exhaust system (silencers and emissions)

Adjustments are made depending on the overall state of the equipment. Load tests are also carried out regularly to ensure all operating parameters remain within optimal limits, and alarm and safety systems are verified to guarantee an effective response if triggered.

Thanks to this process, critical infrastructure – including hospitals, data centres and industrial plants – can continue to operate in emergencies. Lives are saved, information is protected, essential services remain functional, and the supply chain stays active. In short, maintenance turns generators into a true guarantee of continuity.

More Than Just a Response: The Broader Benefits of Preventive Maintenance

In addition to ensuring an immediate response during a power failure, preventive maintenance brings a host of long-term benefits that directly impact safety, efficiency and operational profitability:

  • Safety. Proper maintenance prevents internal failures that could lead to accidents such as fires or explosions, protecting both people and property.
  • Improved performance and lifespan. Regular checks and adjustments reduce premature wear and tear, ensuring the genset runs in optimal condition.
  • Lower costs. Early fault detection helps avoid costly repairs. A well-maintained generator also consumes fewer resources (fuel, coolant, etc.).
  • Regulatory compliance. In many sectors, having generators is not only essential, but so is complying with specific maintenance regulations. Avoiding fines is also part of good management.
  • Business reputation. A preventable failure due to poor maintenance can severely damage a company’s image – especially if it puts customer service at risk.

The Genesal Energy Experience

Genesal Energy knows that the key to ensuring energy continuity lies in foresight and maintenance. A generator is only useful if it’s ready to run when the time comes. That’s why, in addition to designing and manufacturing tailor-made power solutions, we offer a comprehensive Technical Support Service (SAT) to accompany each customer throughout the entire lifecycle of their equipment.

Through it, we define, design and implement maintenance plans tailored to the specific needs of each installation, with 24/7 expert support. We also handle generator installation and commissioning, ensuring everything is ready to respond to any contingency.

One clear example of this capability was our response to the blackout on the 28th of April. Given the scale of the event, we activated a crisis unit to resolve as many incidents as possible, prioritising the most urgent. Thanks to the commitment and professionalism of our technicians, we managed to restore power to numerous critical locations, delivering energy where it was needed most.

Genesal Energy promotes sustainability in the largest wastewater treatment plant (WWTP) in the Valencia Region

/in , /by

Three unique generator sets were designed and installed to optimise the purification processes.

Genesal Energy has made a decisive contribution to the ambitious renovation and optimisation project of the Pinedo Wastewater Treatment Plant (WWTP), in Valencia. This plant is the largest sewage and wastewater treatment facility in the Valencian Community and one of the largest in Spain. With a total treatment capacity of 324,800 m3/day, it serves more than 1.5 million inhabitants of Valencia and 18 municipalities in its metropolitan area.

Within this modernisation framework, Genesal Energy has designed and supplied three generator sets tailored to the infrastructure that guarantee the continuity of the electricity supply in the event of possible power cuts or voltage variations. This allows the uninterrupted operation of the treatment plant’s equipment and ensures the quality of the service.

The most important improvements are those aimed at increasing the plant’s electricity production to make it self-sufficient.

The project – with an overall budget of more than 34 million € – seeks to transform the Pinedo WWTP into a more energy-efficient infrastructure, reliable in its processes and respectful of the social and environmental surroundings. Renovating technology, reducing environmental impact, and optimising operation.

Genesal Energy has provided the project with a customised solution through the installation of two generator sets in containers (1900 kVA + 1250 kVA) and a soundproofed generator set in a canopy with a power of 900 kVA.

Safety for a key infrastructure

The Pinedo WWTP plant was built in 1981. Back then, the need to harmonise infrastructure with the surroundings was not so important in water treatment projects and technologies.

Lately, the treatment plant has been the subject of complaints from the residents of the Valencian district in which it is located. For years, they have been requesting the closure of the facilities due to the nuisance caused by its operation.

Notwithstanding, the renovation of the WWTP includes innovative measures, such as the updating of the computer system for automation and control of the treatment plant, optimizing and reducing the total energy consumption of the facilities by 8%. In addition, a 1,000-kW solar photovoltaic plant, thermal hydrolysis systems have been implemented to increase biogas production and reduce waste.

Renovating technology, reducing environmental impact, and optimising operation.

In the words of the engineering department ‘these measures seek to minimise the environmental impact and improve the quality of the water treated, consolidating the Pinedo WWTP as a modern, sustainable facility that is in harmony with its surroundings.’

Genesal Energy is proud to have contributed with its experience in distributed energy to such a relevant project, reaffirming its commitment to efficient and reliable energy solutions adapted to the needs of each client.

Our engineering solution

The most important improvements are those aimed at increasing the plant’s electricity production to make it self-sufficient. Namely, increasing the cogeneration capacity to reach an electrical power of 2,660 kW, the transformation of the free space of the installation into a 1,000-kW photovoltaic solar plant and the installation of a thermal hydrolysis system of sludge. This last improvement will increase the production of biogas. Reducing energy consumption and the sludge produced will reduce noise and odours caused by the transport of sludge extracted from the facilities.

Operating Cost Calculation for Generator Sets

Operational Cost Analysis: Diesel vs Gas in Generator Sets

/in /by

Visual comparison of Genesal Energy generator sets highlighting operating costs for diesel and gas generator sets.
Choosing the right fuel type for a generator set is a critical decision that directly impacts operational costs and the efficiency of the power supply. The most common options are diesel generators and those powered by natural gas. This article provides a comparative overview of both systems, examining their advantages, disadvantages, and suitability based on the energy demands of each sector.

Factors Influencing the Operational Costs of a Generator Set

The operational cost of a generator set depends on more than just the fuel price. Other key factors include:

  • Fuel consumption according to load and operating hours.
  • Maintenance frequency and spare parts requirements.
  • Engine durability, depending on the type of fuel used.
  • Fuel supply availability and logistics at the project location.
  • Thermal performance and energy conversion efficiency.
  • Environmental regulations relating to fuel emissions.

These elements influence long-term investment, especially in industrial environments or critical applications where continuity of power supply is essential.

The most common options are diesel generators and those powered by natural gas.

Price Comparison: Diesel vs Natural Gas

Diesel has long been a reliable choice, but the price of natural gas is often more competitive, particularly for long-duration or continuous-use applications.

  • Diesel is subject to volatile pricing, influenced by global markets and specific fuel duties.
  • Natural gas generally offers more stable and predictable costs, making operational and financial planning easier.

Genesal Energy Diesel Generator Set and Fuel Fluid
Furthermore, long-term contracts with gas suppliers allow many industries to manage their operating energy costs more effectively.

Efficiency and Fuel Consumption: Diesel vs Gas Generators

Diesel generators typically deliver high efficiency under variable load conditions and quick start-up, making them ideal for short-duration or standby use. Their design allows for high power output within a short time frame.

In contrast, natural gas generators offer:

  • Lower specific fuel consumption in continuous, stable-load operations.
  • Cleaner combustion with fewer residues.
  • Improved thermal efficiency, particularly when used in combined heat and power (CHP) systems.
  • Lower noise and vibration levels, enhancing operational comfort.

Impact on Lifespan and Maintenance of Generator Sets

The type of fuel also affects equipment lifespan and maintenance needs:

  • Diesel engines require more frequent maintenance, including regular oil and filter changes and injector checks.
  • Natural gas engines generally allow longer intervals between servicing, with some models offering up to double the maintenance cycle compared to diesel engines.

However, gas engines require specific components, such as spark plugs and advanced air-fuel mixing systems, which demand specialised care.

Generator sets must meet new market challenges with the lowest possible operating cost and the highest commitment to sustainability.

Industrial Applications and Energy Demands Based on Fuel Type

The choice between diesel and gas depends on the specific power supply needs and application context:

  • Diesel generators: well-suited for emergency backup, quick starts, mobile use, and remote areas without gas infrastructure.
  • Gas-powered generator sets: ideal for continuous operation, thermal-electric cogeneration, and facilities with access to natural gas or biogas networks.

Industries such as manufacturing, logistics hubs, hospitals, data centres, public infrastructure, and agri-food facilities can benefit from either type depending on operational requirements.
Industry with High Energy Demand

Sustainability and Emission Reduction with Natural Gas

Natural gas is increasingly seen as a more environmentally friendly alternative to fuels such as diesel:

  • Significant reduction in NOx, CO₂, SO₂ and suspended particulate matter (PM10 and PM2.5), mainly generated by incomplete combustion in diesel engines.
  • Reduced impact on air quality, especially in urban or enclosed environments.
  • Lower odour and noise pollution.
  • Reduced risk of soil contamination in case of leaks.

In addition, using biogas or renewable natural gas brings operations closer to carbon neutrality, in line with European decarbonisation goals.

How to Choose the Best Option for Your Power Supply Needs

Deciding between gas and diesel depends on several key considerations:

  • Expected operating duration of the generator set (standby vs continuous).
  • Fuel availability and delivery logistics in the area.
  • Environmental restrictions and local regulations.
  • Climatic conditions and technical project requirements.
  • Available budget, covering both CAPEX and OPEX

For projects requiring long annual operating hours, gas is often more cost-effective in the long term. In contrast, for installations with sporadic use or urgent demand, diesel remains a robust and practical choice.

Trends and the Future of Fuel Use in Generator Sets

The shift towards a cleaner energy model is encouraging the adoption of alternative fuels, such as biogas, LPG, green hydrogen, or HVO blends (hydrotreated vegetable oil).

In addition, using biogas or renewable natural gas brings operations closer to carbon neutrality,

Hybrid systems that combine generator sets with renewable energy and battery storage are also gaining traction, offering more flexible and sustainable power solutions.

In the short to medium term, natural gas will remain a key solution for efficient and sustainable electricity generation, particularly in industrial settings and medium-to-large-scale projects.
Meanwhile, diesel generators will continue to play a vital role in applications requiring immediate response and proven reliability, such as hospitals, telecommunications, and emergency systems.
Hand touching a moss-covered log in a natural environment
Ongoing technological development, tighter environmental regulations, and the demand for flexible energy solutions will shape the sector’s future, where generator sets must meet new market challenges with the lowest possible operating cost and the highest commitment to sustainability.

Power Generator for Extreme Climates

Genesal Energy, delivering energy in the most extreme climates

/in , /by

Securing energy supply in climates with extreme conditions, be it cold, heat or humidity, is a challenge that Genesal Energy is familiar with. In this case, the challenge of the project was to provide a solution in the extremely cold environment of Finland.

Faced with the need for reliable equipment to ensure the uninterrupted operation of the installation in the event of a mains power failure, we designed a generator set fully integrated into a 20 feet HC container, adapted to the demands of the environment and prepared to guarantee the continuity of the power supply. In addition, it had to be able to operate in low temperature conditions, be compact for easy transport and have the greatest possible autonomy. A technical challenge that we solved with a customised design.

Another key aspect of the design was the optimisation of space to increase the autonomy of the equipment.

To guarantee the correct operation of the unit in these climatic conditions, we incorporated a system of motorised grilles between the unit and the air outlet. These louvres allow air inlets and outlets to be closed, while the opening of an intermediate louvre creates a flow of hot air inside the container until the right temperature is reached. It is equipped with a heating recirculation pump to guarantee start-up in extreme conditions. At the same time, customised soundproofing ensures that the noise level is extremely low.

Another key aspect of the design was the optimisation of space to increase the autonomy of the equipment, so we designed a customised fuel tank with a capacity of 2,000 litres, with a double steel wall and strategically located at the entrance of the container.

Mobile Generator Set for Wind Turbine Blade Recycling

Genesal Energy promotes sustainability in wind farms with a mobile generator set for the recycling of turbine blades.

The energy transition and the fight against climate change have boosted the development of wind energy, making it one of the main renewable sources worldwide. However, this progress brings with it a significant challenge: the efficient recycling of wind turbine blades.

With an average lifespan of 20 years – extendable to 25 with proper maintenance – most components of a wind turbine are recyclable. However, blades present a unique challenge due to the composite materials used in their manufacture: glass & carbon fibre and resins. These materials are complex to separate, which raises costs and makes large-scale recycling difficult.

Genesal Energy has taken a step forward in search of sustainable solutions to this challenge. In collaboration with GDES Wind – a company specialised in the maintenance and inspection of blades in wind farms – we designed and installed a 45 kVA mobile generator set to power a machine specialised in the recycling of wind turbine blades. This equipment cuts the blades using diamond wire, offering an efficient and environmentally friendly alternative. The pieces are then efficiently treated as waste, generating mortar or useful pieces for new applications such as planters, canopies or pieces of furniture.

With this project, Genesal Energy reinforces its commitment to sustainability and the circular economy.

This genset – which complies with Stage V emissions standards – not only ensures a low environmental impact but also provides autonomy of up to 35 hours at 100% load thanks to its 350-litre tank. It is also equipped with a socket panel to power auxiliary tools, extending its functionality and operational efficiency.

A growing challenge in the wind power industry

Although most blades are currently reused in repowering processes or converted into architectural structures such as bridges or bicycle racks, this strategy will not be sufficient in the long term. According to WindEurope, up to 5,700 wind turbines per year will be dismantled in Europe from 2030 onwards, which means an increasing volume of retired blades that will require innovative solutions for recycling.
