How does AI help reduce our costs?

AI lowers energy expenses by forecasting demand, intelligently balancing energy use, and enabling the sale of surplus electricity back to the grid.

Do employees need special training to use the system?

No special training is required. Our fully automated platform integrates seamlessly into existing operations, minimizing onboarding time and ensuring fast, cost-effective deployment across any facility.

What are the benefits of having your own microgrid?

A microgrid provides a high level of energy independence, allowing you to produce, store, and manage your own electricity on-site. This reduces your reliance on the main grid and protects your operations from power outages or unstable supply. It can integrate multiple energy sources for greater flexibility, improve efficiency through smart controls, and significantly reduce operating costs. In addition, a well-designed microgrid lowers your environmental footprint and can open opportunities for selling surplus energy back to the grid in markets where it is allowed.

Can a microgrid work completely off-grid?

Yes. A microgrid can be designed to operate fully off-grid, generating and storing all the power required for your facility without any connection to the central grid. This is particularly valuable for remote sites, industrial operations in areas with unreliable grid access, or businesses seeking complete control over their energy production. With the right combination of generation, storage, and management systems, an off-grid microgrid can provide consistent, reliable power 24/7.

What types of energy sources can be integrated into a microgrid?

Our microgrids are designed to be versatile and adaptable, capable of integrating a wide range of energy sources. These include natural gas, biogas, mine methane gas, landfill gas, solar photovoltaic (PV) panels, wind turbines, and battery energy storage systems. This mix allows you to combine renewable and conventional sources to maximize reliability, reduce costs, and meet sustainability targets. The choice of sources depends on your location, fuel availability, and operational priorities.

How do you ensure the reliability of your microgrid systems?

We use only high-quality, industry-proven components, combined with advanced control systems and redundancy measures to minimize downtime. Every microgrid is equipped with real-time monitoring and AI-driven performance optimization, which predicts potential issues before they cause disruptions. Our designs often include backup generation and energy storage to provide an additional layer of security, ensuring that critical loads are always supplied, regardless of external conditions.

How much can I save with a microgrid?

Savings vary depending on your energy demand, fuel costs, and system design, but many of our clients achieve up to 20% lower energy costs compared to relying solely on the central grid. Additional savings can come from avoiding peak demand charges, reducing fuel waste through efficient generation, and optimizing the mix between self-generated and purchased power. In some cases, excess electricity can be sold back to the grid, creating a new revenue stream.

What is a CHP (Combined Heat and Power) system?

A CHP system, also known as cogeneration, simultaneously produces electricity and captures usable heat that would otherwise be wasted during generation. This heat can be used for space heating, hot water, industrial processes, or even cooling via absorption chillers. By using both the electrical and thermal output, CHP systems can reach efficiency levels of 80–90%, compared to around 40% for traditional power generation.

What is the difference between a CHP and a regular gas engine?

A regular gas engine generates electricity only, while a CHP system makes use of both the electricity and the heat it produces. This makes CHP far more efficient and cost-effective for facilities that can use the recovered heat, such as manufacturing plants, greenhouses, hospitals, and district heating networks. The dual output helps reduce fuel consumption, lower emissions, and cut overall energy expenses.

Do you provide both electrical-only and cogeneration systems?

Yes. We offer electrical-only gas engine solutions for clients who need power without heat recovery, as well as CHP systems for those who can utilize both electricity and heat. Our engineers work with you to determine the best solution based on your site’s energy profile, fuel availability, and long-term operational goals.

Can you customize a CHP system for my specific needs?

Absolutely. Every CHP project we deliver is tailored to the client’s unique energy requirements. We take into account your electrical and thermal demand, available fuel types, space constraints, and operational schedule. From there, we design, supply, and install a system that maximizes efficiency and ensures long-term performance, whether you need it for a single facility or an entire energy network.

How do I get started with installing a microgrid or CHP system?

The process begins with a detailed consultation and energy audit to understand your current consumption, infrastructure, and future goals. Based on this analysis, we develop a custom system design, then handle all stages of the project — from engineering and equipment supply to installation, commissioning, and staff orientation. We also provide ongoing monitoring and support to ensure your investment delivers maximum value over its lifetime.

What level of customer involvement is required during the project?

We manage the entire process on your behalf, minimizing the time and resources you need to commit. Your role typically involves approving key design decisions, providing access to site data, and reviewing progress at agreed milestones. Our project team takes care of the technical, regulatory, and installation work, so you can focus on running your business while we deliver your new energy system.

Do I need special training to operate your systems?

No special training is required. Our systems are fully automated, with AI-driven controls and remote monitoring to handle daily operation. If desired, we can provide a short orientation for your staff, covering basic functions and safety procedures, but the technology is designed to run efficiently with minimal human intervention.

What kind of maintenance is required?

Maintenance requirements are low thanks to advanced monitoring and predictive diagnostics, which allow us to detect and address issues before they impact performance. Our service team schedules regular inspections, performs preventive maintenance, and manages any necessary repairs. We also keep critical spare parts available to ensure minimal downtime and extend the life of your system.

How much CO₂ reduction can I achieve with your solutions?

Depending on the fuel type and system design, our solutions can reduce CO₂ emissions by up to 40% compared to a conventional energy supply. This is achieved through higher efficiency, integration of renewable sources, and reduced transmission losses.
