Genesal Energy works every day to deliver power solutions that protect what matters most. And few things are more essential to life than access to clean drinking water.
That’s why we’re proud to have contributed to safeguarding this vital resource at water treatment plants in Lithuania, where we supplied five generator sets specifically designed to ensure continuous operation of the facility in the event of a power failure.
The plants play a key role in the daily water supply and in the treatment of wastewater. It required a reliable backup power system capable of activating instantly in the event of a grid outage, as any disruption could compromise critical processes such as pumping, purification, or waste control. In real terms, this could lead to homes without water, health risks, or serious environmental impacts.
The Genesal Energy engineering team designed the generator sets to activate immediately in the event of a power failure.
Our engineering team designed a solution made up of five generator sets: two 110 kVA units and three 275 kVA units, all installed in soundproof enclosures and equipped with high-capacity fuel tanks made of stainless steel – a material especially resistant to humidity and corrosion. Key design features included a flexible coupling system between the engine and alternator, a low-noise configuration (-30 dB), and 500W and 1,000W engine heaters to enable efficient cold starts.
Additional features included digital oil level sensors and a special RAL 5012 paint finish, customised to the client’s specifications.

Decarbonisation in industry is not just about technology: it’s about acknowledging operational complexity and the need to combine multiple solutions. Genesal Energy knows this well. That’s why we chose to take action.
Our renovation of units B27 and B28 at the Bergondo industrial estate (A Coruña) is a real example of how to integrate concrete, measured, and coordinated efforts to move towards a more sustainable industry.
Producing renewable energy is not enough, you also need to manage it properly.
In recent years, we’ve taken an active role in the energy transition, convinced that decarbonising our processes is not a choice but a responsibility. However, we are under no illusion: the path is not easy. Challenges are high energy consumption, demanding technical processes, and above all, the need to ensure uninterrupted operational continuity. We understand there is no single solution or magic formula. Every industry is different, and every step matters.
In our case, the first step was analysis. We studied our energy consumption, losses, thermal demand, and the renewable potential of our facilities in depth. Based on that data, we designed an intervention around four pillars:
Integration of renewable energy
Smart energy management
Recovery of energy flows
Overall efficiency improvement
For renewable generation, we chose to integrate the solution into the architecture of our buildings. We installed 111 sq metres of photovoltaic glass with a capacity of 13.1 kWp directly into the façades, allowing us to generate clean energy while also improving thermal insulation. This was complemented by a 252 m² photovoltaic roof (57.3 kWp) on unit B27. Thanks to these installations, we now cover 100% of the energy consumption of both units during peak solar hours.
But producing renewable energy is not enough, you also need to manage it properly. That’s why we incorporated the OGGY, an advanced energy storage and management system that monitors usage in real time and automatically determines the most efficient use of the available energy. This system helped us reduce consumption by 27% in just one year.
There is no single solution or magic formula. Every industry is different, and every step matters.
We went one step further: we began recovering the energy generated during genset testing (FATs). Thanks to its integration with OGGY, that energy is fed back into the system, further reducing our dependence on the electricity grid.
The results came quickly: in the first year, we avoided more than 23 tonnes of CO₂ equivalent emissions. Our facilities also improved their energy certification, moving from a rating of “E” to “B”. An improvement that reflects not just efficiency, but a genuine commitment to sustainability.
This project has shown us that industrial decarbonisation is not achieved through isolated grand gestures, but through concrete, measurable, and coordinated actions. It requires vision, strategy, and the ability to adapt solutions to the specific needs of each operation. And above all, it requires commitment.
Genesal Energy is clear on this: we’ll keep moving forward.

Genesal Energy’s sustainability commitment is tangible, reflected in real-world projects. One such initiative is the integration of HVO (Hydrotreated Vegetable Oil) into generator set testing—an important step towards a cleaner energy model that maintains the reliability and quality for which the company is known.
HVO is a second-generation biofuel produced from organic waste such as used cooking oils and animal fats. These feedstocks undergo a hydrotreatment process that removes impurities and enhances fuel properties, resulting in a product with characteristics very similar to—if not superior to—conventional fossil diesel. One of its main advantages is that it can be used in existing engines, fuel tanks and storage systems without the need for modification, allowing direct deployment within current infrastructure.
Every step towards a more sustainable energy model must be based on independent validation, technical reliability, and a commitment to quality.
In addition to its compatibility, HVO offers key environmental benefits. It can reduce lifecycle CO₂e emissions by up to 90% compared to standard diesel, supports the circular economy by repurposing waste, and avoids the ethical conflicts often associated with first-generation biofuels derived from food crops. As a result, HVO has become a key tool in the energy transition: a practical, progressive and realistic pathway towards industrial decarbonisation. It is already part of Genesal Energy long-term sustainability strategy.
This solution is particularly relevant in sectors where energy reliability is critical and environmental requirements are increasingly strict—such as data centres, defence, healthcare and telecommunications. In these environments, HVO allows organisations to move forward with decarbonisation goals without compromising operational security or power continuity.
Ensuring Quality in Real-World Conditions
The shift to HVO was not based on laboratory trials or isolated testing. Genesal Energy sought to validate the fuel’s behaviour under real-world operating conditions, applying the same level of technical rigour required of every system component.
To achieve this, two generator sets representative of typical product applications were selected: a 100 kVA and 200 kVA units in Spain. Both were already in active service, supplying energy to installations under standard daily load and operational demands. These conditions offered an authentic view of how HVO performs in routine use and within the environments where it must deliver value.
Real-world testing and laboratory analysis confirm that HVO is a high-quality, dependable fuel solution—ready to meet the challenges of the energy transition.
Fuel samples were taken directly from the gensets, without altering or manipulating the product. These were submitted to an independent, accredited laboratory for full testing and verification against all required specifications and standards for safe, efficient use in diesel engines.
This approach reflects the company’s technical philosophy: every step towards a more sustainable energy model must be based on independent validation, technical reliability, and a commitment to quality. It is not enough for a fuel to be cleaner—it must also meet the performance and durability standards that define Genesal Energy solutions.
Test Results: Confirming HVO’s Quality and Reliability
The laboratory analysed the samples in accordance with UNE-EN 15940, the European standard for paraffinic synthetic and bio-based diesel fuels. Key parameters assessed included:
Density: Crucial for energy yield per combustion cycle. The measured density fell within the standard limits, ensuring consistent engine performance without the need for recalibration or risk of increased consumption.
Kinematic viscosity: Essential for proper fuel flow, lubrication, and injector spray pattern. The tested HVO met all viscosity requirements, supporting complete combustion and preventing deposit formation or clogging.
Distillation curve: Confirmed stable fuel volatility across temperature ranges, ensuring efficient evaporation and ignition under varying load conditions.
Cold behaviour: The fuel demonstrated excellent performance in low temperatures, avoiding filter blockage or crystallisation. This makes it well suited to variable climates and reduces the need for additional maintenance precautions.
Cetane number: Indicative of ignition quality under compression. The high cetane value contributed to smoother starts, fewer emissions on ignition, and stable engine operation throughout usage.
Water and solid content: Low levels were recorded, within safe limits, reducing the risk of corrosion, wear, and system contamination—key to maintaining genset durability.
Overall, the results confirm that HVO complies with all regulatory and technical requirements for safe diesel engine operation. Most importantly, it offers seamless integration with existing systems, enabling immediate adoption in projects where full electrification is not yet feasible from a technical or economic standpoint. This positions HVO as a realistic and effective solution for decarbonisation without sacrificing performance or reliability.
Conclusión
Real-world testing and laboratory analysis confirm that HVO is a high-quality, dependable fuel solution—ready to meet the challenges of the energy transition. Its adoption supports a dual goal: reducing the carbon footprint of distributed generation systems while maintaining the security and effectiveness expected in critical infrastructure.
HVO is a second-generation biofuel produced from organic waste such as used cooking oils and animal fats.
Genesal Energy’s use of HVO is not a symbolic gesture but a strategic commitment combining technological innovation, environmental responsibility and technical excellence. Every step forward is backed by data, independent validation, and a clear focus on delivering reliable, sustainable energy solutions.
Looking ahead, the company will continue to explore and validate emerging technologies that enable clients to decarbonise their operations with confidence—because sustainability is not something to declare, but something to prove.

Generator sets are essential to ensure uninterrupted power supply in remote locations, critical facilities, or areas with an unstable grid. However, when exposed to extreme conditions—scorching heat, freezing cold or high altitudes—specific solutions must be applied to guarantee optimal performance and extend equipment lifespan.
Challenges of Operating Generators in Extreme Conditions
Environmental factors can directly impact a generator’s performance, reliability and durability. Extreme temperatures, humidity, dust, and even air density at high altitudes present technical challenges that require proper equipment preparation.
The main challenges include:
Increased wear on mechanical and electronic components.
Need for reinforced cooling systems.
Overcoming these challenges demands adaptive engineering, durable materials, and an optimised configuration tailored to each environment.
Adaptations for Cold Climates: Generators in Arctic Zones
In polar or mountainous regions where temperatures drop well below zero, a standard generator may struggle to operate reliably. To ensure performance in these environments, several measures are implemented:
Engine and fuel preheating systems, enabling starting in temperatures as low as -30 °C.
Thermally insulated enclosures to shield internal components from extreme cold.
Low-viscosity lubricants and fuels suitable for Arctic climates.
Battery and alternator heaters.
These adaptations ensure that the generator can effectively meet critical energy needs, for instance in scientific bases, telecommunications infrastructure, or emergency systems in sub-Arctic areas.
Operation in High Temperatures: Solutions for Desert Environments
In desert climates—where temperatures can exceed 50 °C and dust levels are high—several parts of the generator must be reinforced:
Oversized cooling systems, with additional fans or high-efficiency radiators to prevent overheating.
Specialised air and dust filters to block abrasive particles from entering the engine.
Protection of electronic components from direct solar radiation.
UV-resistant paints and coatings.
The goal in these environments is to keep engine temperature within safe operating ranges and prevent dirt accumulation that could impair combustion or damage components.
The Importance of Cooling Systems in Extreme Conditions
Cooling systems are critical for generator sets exposed to extreme temperatures. Whether in high heat or freezing cold, efficient thermal management is essential to avoid mechanical failure, efficiency loss or irreversible engine damage.
Common cooling solutions include:
Liquid cooling with special antifreeze for cold environments.
Tropical-grade radiators or large-capacity heat exchangers for hot climates.
Redundant ventilation or forced-air cooling systems.
Continuous monitoring of temperature and cooling pressure helps extend the generator’s lifespan and ensures optimal performance.
How Altitude and Air Density Affect Generator Performance
As altitude increases, air density decreases, which negatively affects combustion and, consequently, the power output of the generator. This results in:
Reduction in rated power (up to 10% for every 1000 metres above sea level, depending on the model).
Increased load on the intake and exhaust systems.
Requirement for specific calibrations to adjust the air-fuel mix.
Therefore, for applications in mountainous or high plateau areas, the generator must be calibrated and fitted with systems to offset these conditions, such as tuned turbochargers or adapted electronic configurations.
Protection and Maintenance to Prolong Equipment Life
Generators designed for extreme environments require a stricter maintenance plan and additional protective measures:
More frequent inspection of filters, oil and coolant.
Regular checks of the electrical system and thermal insulation.
Preventive cleaning to counteract sand, ice or salinity depending on the environment.
Use of anti-corrosion coatings and components resistant to thermal shock.
These measures not only help avoid breakdowns, but also ensure reliable performance in the harshest conditions.
Use Cases and Applications in Critical Sectors
Generators engineered for extreme conditions are vital in sectors where power failure is not an option:
Defence and security: military operations in desert or polar zones.
Oil and gas: platforms or fields in remote or hostile regions.
Emergency and rescue: humanitarian camps or temporary installations.
Scientific exploration: Arctic research stations or desert locations like the Sahara or Atacama.
High-altitude mining: projects in the Andes or the Himalayas.
In all these cases, generator design must meet specific power requirements with long-term reliability, performance and resilience.
Technological Trends to Enhance Generator Resilience
Technological advancements continue to improve generator resistance to extreme environments:
Smart sensors and IoT systems for remote monitoring of operating conditions.
Self-diagnosis systems to detect faults before they occur.
New insulating and lightweight materials that better withstand thermal and mechanical stress.
Compact, modular designs for easier transport and installation in remote locations.
In addition, alternative fuels such as HVO or natural gas are being integrated, offering more stable performance under certain environmental conditions.
Conclusion
Preparing a generator set for extreme conditions is not optional—it is essential to ensure operational efficiency and performance. From the Arctic to the desert, each environment demands a tailored technical approach adapted to its temperature, altitude and energy requirements. Investing in robust, well-designed and properly maintained equipment is the best way to guarantee long-term reliability.

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 project developed in Belgium is a clear example of Genesal Energy’s commitment to tailor-made engineering, sustainability and energy efficiency applied to critical infrastructures. From design to commissioning, every decision was aimed at ensuring maximum operational reliability, environmental responsibility and compliance with the most demanding European standards.

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.

“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)
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.
