Biogas Generator Systems for Livestock Farms

What Is a Biogas System on a Livestock Farm? How It Works and How to Choose a Biogas Generator

A Biogas Generator Set is a power generation system that uses biogas as fuel to drive an engine, which then transfers mechanical power to a generator to produce electricity.

Biogas primarily consists of methane (CH₄) and carbon dioxide (CO₂), along with other gases and impurities. The composition varies depending on the feedstock and the biogas production process.

Biogas Generator A biogas generator operates on the same basic principle as other generators powered by internal combustion engines. The main difference is that biogas is used as the fuel instead of diesel or other conventional fuels.

Biogas is supplied to the engine’s fuel system, where it is combusted inside the engine to generate mechanical power. This rotational power is then transferred to the Generator or Alternator to produce electricity.

System performance does not depend solely on the generator’s capacity. Several other factors must also be considered, including:

• Daily biogas production volume
• Methane concentration in the biogas
• Consistency of the gas supply
• H₂S and moisture levels
• Gas pressure before entering the engine
• The farm’s electricity consumption pattern
• Electrical load size and characteristics
• Generator operating hours
• Cooling and lubrication systems
• Generator control and protection systems

For this reason, selecting a biogas generator should involve evaluating the entire system, from the biogas production source to the electrical loads. The generator should not be selected based solely on its kW or kVA rating.

Why Should Livestock Farms Have a Backup Power System?

Livestock farms rely on many types of equipment that need to operate continuously, such as ventilation fans, water pumps, feeding systems, temperature control systems, cooling systems, lighting, and automated control systems.

If a power outage occurs, these systems may stop operating at the same time. Having a backup generator allows essential electrical loads to be supplied with power quickly, particularly on farms where maintaining stable environmental conditions inside livestock buildings is critical.

The system can be designed to operate with an ATS (Automatic Transfer Switch). The ATS monitors the main power supply. When the main power fails, the system automatically signals the generator to start and transfers the electrical supply to the generator according to the predefined sequence.

How to Choose the Right Generator Size for a Farm

Generator sizing should not be based solely on the total rated power of all connected equipment. Certain equipment, such as motors, water pumps, and large ventilation fans, may draw significantly higher current during startup than during normal operation.

Engineers should therefore consider kW, kVA, Power Factor, Starting Current, and the operating characteristics of the electrical loads, as well as the sequence in which equipment is started.

For example, if a farm has large water pumps and a large number of ventilation fans, selecting a generator based only on the equipment’s normal operating power may not be sufficient. The motor starting current must also be evaluated, and an appropriate load sequence should be established.

For biogas systems, the actual volume of biogas produced and the quality of the gas must also be considered to ensure that the engine can operate efficiently and reliably.
