Cogeneration Plant: What It Is and How It Works
Updated by Sargon – an expert in energy solutions and engineering systems.
What is a cogeneration plant
A cogeneration plant is an energy complex that allows simultaneous production of electrical and thermal energy from a single type of fuel. Typically, natural gas is used as the energy carrier, but biogas, diesel, or even solid fuel can also be applied.
In simple terms, cogeneration is a technology that allows maximum efficient use of fuel by converting heat losses into useful energy. Thanks to this, the efficiency coefficient (COP) of such plants can reach 85–90%.
Operating principle of a cogeneration plant
The basis of a cogeneration complex is an engine or turbine that rotates an electric generator. During electricity production, a large amount of heat is released, which in traditional systems is lost, but in cogeneration systems is returned to the heating system or hot water supply.
The operating principle of a cogeneration plant includes three main stages:
- Fuel combustion (gas, biogas, diesel).
- Energy conversion into electricity through a generator.
- Heat recovery from exhaust gases and cooling fluid for heating needs.
Thus, the plant simultaneously produces electricity and heat, making it an ideal solution for enterprises, hospitals, heat supply companies, and business centers.
Types of cogeneration systems
- Gas-piston cogeneration plants – operate on natural gas, have high efficiency and stable operation.
- Gas turbine plants – efficient with large volumes of energy consumption.
- Biogas plants – used in the agricultural sector, at MSW landfills, or wastewater treatment facilities.
- Solid fuel cogeneration plants – solutions for facilities without gas pipeline access.
Benefits of cogeneration
- Reduction of energy costs by up to 40%.
- Minimization of harmful atmospheric emissions.
- Autonomy and stability of energy supply.
- Project payback period from 2 to 5 years.
- Possibility of use in centralized heating systems.
Applications of cogeneration plants
Cogeneration systems are used in various industries:
- at industrial enterprises – for own energy supply;
- in municipal heat supply – for boiler houses, CHPs, residential areas;
- in healthcare – for hospitals where uninterrupted power supply is important;
- at agricultural facilities – for biogas utilization.
Installation of cogeneration plants
The installation process includes design, equipment selection, connection to the power grid and heating systems, as well as automation setup. Sargon implements a full cycle of work – from technical specifications to commissioning.
