Reliable energy production by Eltrak

Everything you need to know about energy generation and how you will find the generator that suits you.

Imagine being in the middle of a technical project, a shift in a factory, or a data center and the power goes out. What would happen? Chaos and anxiety would likely ensue, and work would come to a halt. Power generation keeps everything moving and reliable energy is essential for the smooth functioning of homes, hospitals, worksites, factories, hotels, data centers and so much more. Generators are the unsung heroes that will keep providing power even in the most unwelcoming conditions, ensuring efficiency and productivity are maintained.

The importance of reliable energy

Reliable energy is the backbone of modern society, powering houses, businesses, hospitals, and emergency services. Generators are one of the best ways to ensure consistent and dependable power, especially in areas with unstable or non-existent electrical grids. They also play a crucial role in maintaining productivity and efficiency, ensuring operations run smoothly without interruptions.

Different energy sources

As the energy landscape rapidly evolves, so do the available energy sources, such as solar, wind, hydro, and gas. Each offers a unique set of benefits and opportunities. The most common energy sources you will encounter in generators and generator sets are diesel (biodiesel, HVO, etc.) and gas (natural gas, biogas, propane, etc.).

Diesel as an Energy Source

Diesel generators convert some of the chemical energy in diesel into mechanical energy, which is then converted into electricity.

These generators are installed everywhere and can function as the primary power source in the absence of a supply network and as a standby source in case of an energy supply interruption from the provider.

Gas Energy Solutions

Gas (natural gas, biogas, propane, etc.) comes as a sustainable, economical, and efficient alternative to conventional fuels. They reduce greenhouse emissions, generate revenue by sharing gas energy with the grid, Reclaim valuable land normally used for wastewater purification, and eliminate odor and pest issues.

You can further enhance efficiency, by incorporating a combined heat and power (CHP) system into your gas infrastructure. CHP systems generate both electrical and thermal energy, which can be used to provide space heat and hot water. You most often see them as great profitable and sustainable solutions for greenhouses.

Hybrid Energy Solutions

Caterpillar's Hybrid Energy Solutions (HES) combine renewable energy sources, such as wind and solar, with traditional diesel or gas generators. The addition of lithium battery energy storage systems (BESS) makes these systems more stable and efficient. They can operate independently or in conjunction with the main electrical grid.

Eltrak’s role in the energy transition

Through the official representation of Caterpillar in the Greek market, we help our customers transition to a lower-carbon economy. Caterpillar seizes every opportunity, starting with reducing the GHG emissions of their operations and extending to helping their customers achieve their climate-related goals. This is achieved through continued investment in new products, technologies, and services that facilitate fuel flexibility, increased operational efficiency, and reduced emissions.

Main applications of generators

Thanks to their dependability, Caterpillar generators and generator sets are widely used in both commercial and industrial settings.

Generators are valuable, especially in emergencies or routine power outages. Power outages can occur for a number of reasons and a generator ensures that your home or workplace remains operational. Commercial enterprises, in particular, have more at stake than the average homeowner; a few hours of downtime can be very costly. Therefore, companies often invest in standby generators to ensure an uninterrupted power supply.

You will often encounter generators at construction sites, mines or quarries, greenhouses, and industrial areas—generally, locations where the power grid may be unstable or unreliable. They have become a prerequisite in 5-star hotel facilities, data center applications, and hospitals. Additionally, generators are suitable for portable applications such as sporting events, boats, festivals, and more.

Additionally, generators provide a solution as the sole power supply for energy applications in remote areas without a provider, such as in islands or regions near the borders.
