Biogas cogeneration plants

Characteristics of the biogas cogeneration plants

Intergen designs and builds cogeneration plants supplied by biogas, generated from organic materials of a vegetable nature, animals waste, from the dump, organic waste and water purification.

These plants produce electricity which is partly self-consumed and a lot is transferred to the grid with consequent maturing of incentives envisaged by the regulation; at the same time the heat recovered from the discharged fumes and engine cooling can be used directly for the anaerobic digestion plant or for other uses, such as district heating of surrounding buildings.


In the event of use of engines with power over 2 MWe, or even for lower powers if the customer has specific needs, Intergen designs and builds plants assembled on-site, guaranteeing adequate soundproofing, by designing and installing prefab panelled housing.

For the power range between 100 kWe and 2MWe, Intergen designs and builds cogeneration plants in a single container, preassembling most of the components in the factory; a modular composition of more containers makes it possible to obtain any overall power requested by the customer.

This solution guarantees the maximum construction compactness, where all of the plant components are located nearby and in the ideal position which optimises performance; this also makes it possible to reduce on-site installation time to a minimum and the maximum level of construction quality control, including thanks to the final acceptance test performed in the factory at the end of the production process.

The containerised cogeneration plant is the ideal solution for installations where an adequate area is available outside the facility to be served.

For any power requested by the customer, Intergen designs and builds cogeneration plants in buildings, handling on-site assembly of all the components and designing a customised solution which optimises use of the available space.

With this approach it is possible to install plants in existing utility rooms, avoiding having to increase external volumes and minimising the authorisation process.

In addition, after an accurate site inspection, Intergen’s specialised personnel is able to identify the best solution from a performance standpoint, through an in-depth study on the impact of the plant noise, propose sound absorbing panelling assembled on-site which makes it possible to meet the most stringent design limits.
