Supply of cogeneration
installations

Cogeneration is a technology of combined production of electricity and heat within a single unit. Unlike traditional generators, it efficiently uses fuel and minimizes energy losses.

Simultaneous production of two types of energy. The efficiency of such systems reaches 80–90% (compared to 30–40% in conventional generators).

It is used for enterprises, communities, and municipal systems. It allows reducing energy costs and increasing autonomy.

The principle of cogeneration is simple: an internal combustion engine (gas-piston or gas-turbine) generates electricity, while the by-product heat, which is usually wasted, is transferred through a heat exchanger and reused.

This can be for building heating, hot water supply, or technological needs.

Thus, the same amount of fuel provides two types of energy, and in some cases — even three (in trigeneration mode, when cooling for air conditioning is added).

Advantages of cogeneration:

• High energy efficiency (up to 90% instead of 30–40% in classical systems).

• Energy independence of an enterprise from the centralized grid.

• Reduced costs for electricity and heat.

• Possibility of integration with renewable sources (biogas, hydrogen).

• Reduction of CO₂ emissions thanks to rational fuel use.

Disadvantages of cogeneration:

• Initial capital investments.

• The need for a stable fuel source (gas or biogas).

• Economic efficiency depends on market prices for fuel and electricity.

A cogeneration unit is an energy module that simultaneously produces electricity and heat from a single fuel source.

It consists of an engine (gas-piston or turbine), a generator, and a heat exchanger.

Modern units are produced in a containerized “plug-and-play” format — they are easy to transport, connect, and integrate into existing infrastructure.

The power of such systems ranges from several dozen kW to several MW, which allows them to be used both in the hotel business and at large industrial plants.

The operating principle of a cogeneration unit is similar to that of a conventional generator, but with efficient heat utilization.

• The engine generates electricity from fuel.

• By-product heat is collected from the cooling system.

• Thermal energy is used for heating, hot water, or production.

• If integrated with absorption chillers, the unit can also produce cooling (trigeneration).

The process can be described in three stages:

• Electricity generation — the engine or turbine converts fuel into energy.

• Heat recovery — heat is not wasted but directed into the heating system.

• Heat utilization — for heating, hot water supply, or industrial processes.

Thanks to this, the overall efficiency of the unit reaches 80–90%.

Cogeneration mode is a way of operating an energy unit when two types of energy are simultaneously generated and used: electrical and thermal.

In practice, this means that the enterprise receives electricity for its processes while at the same time heating buildings or production facilities.

When chillers are added to the system, the mode shifts to trigeneration: simultaneous production of electricity, heat, and cooling.

Natural gas cogeneration units are the most common solution for businesses and communities in Ukraine. They provide the optimal balance of cost and efficiency. Gas-piston models are suitable for small and medium-sized businesses. Gas-turbine models are designed for large enterprises with high consumption. They save 30–50% of energy costs. They can also work in combination with biogas or hydrogen to increase environmental friendliness.

The fuel for cogeneration can be natural gas, biogas, hydrogen, and propane.

The energy obtained from the cogeneration process can be used for various purposes and in various industries. It is a full-fledged source of energy for:

• meeting own electricity needs of enterprises, industrial and residential buildings, and the grid;
• technological processes, space heating and cooling needs (trigeneration);
• backup power supply.

Yes! A cogeneration system can also meet cooling needs. To do this, we connect an absorption chiller to the cogeneration system so that the waste heat is used for cooling. Such systems are called tri-generation systems because they produce heat, cold and electricity at the same time.

Cogeneration is an environmentally friendly, highly efficient and cost-effective way to generate electricity. The technology reduces greenhouse gas emissions by capturing waste heat from electricity generation and using it for heating. This saves fuel, your costs, and reduces emissions.

Cogeneration is becoming increasingly common in Ukraine, especially among industrial enterprises and commercial facilities. Legislation favoring the development of cogeneration plants and providing them with incentives is contributing to the further growth of this sector. In addition, government programs and initiatives to support renewable energy sources also contribute to the proliferation of cogeneration systems in the country, for example, at biogas plants.

In general, gas turbines, internal combustion engines or piston systems are used for cogeneration. Pro-Energy uses the second and third options for its customers. Our cogeneration units are equipped with gas-piston internal combustion engines.

The actual amount of heat and electricity that can be produced from an installed reciprocating engine cogeneration unit depends on various factors, such as the type and amount of fuel burned. We make individual calculations for each client, taking into account the specifics of their business and goals. We invite you to a consultation where we can provide you with specific data and answer your questions.

You can spend a long time studying complex information about cogeneration technology and still not find answers to your questions. We offer a simpler option. All you need to do is request a free consultation. We will schedule a meeting to help you understand, explain the details and calculate your benefits.

It doesn’t matter where your company is located. A cogeneration plant eliminates your dependence on the power grid and distribution networks. And the plant is usually located near the resource of raw materials and consumers.

To install a cogeneration machine, you only need to provide for the installation:/p>

• Foundation
• Electrical networks for connecting a cogenerator to generate electricity.
• Heating networks for collecting waste heat from the cogenerator.
• Gas networks and communications to supply fuel to the cogenerator.

No special skills are required to maintain cogeneration units from Pro-Energy. Our team will provide you with the necessary skills and instructions to operate the equipment safely and efficiently. After commissioning, we stay with you to provide service and technical support.

In order not to lose the surplus electricity generated, the company can supply it to the power grid for sale on the market and generate additional profit.

The cost of a cogeneration machine is determined individually for each client and depends on various factors, such as the specifics of the enterprise, the capacity of the installation, etc. We invite you to a consultation, where our experts will calculate the cost of installing a cogeneration machine according to your needs.

It’s simple, let’s start our cooperation with a free consultation. First, we will discuss the details of the project, prepare a no-budget plan, and proceed to implementation. Leave a request here and we will start the journey to implementing energy efficient solutions together.
