Walter Wood Chip Power Plants
Walter power plants produce electricity and heat locally from wood chips.
- Fuel wood chips
- Electrical output 50 kW
- Thermal output 120 kW
- Production electricity and heat from the same CHP unit
Electricity and heat from the same fuel
Walter is a power plant designed for combined heat and power (CHP) production.
Wood chips are gasified, and the resulting wood gas is used in a gas engine to generate electricity. The heat produced at the same time is recovered and can be used, for example, for heating buildings, industrial processes or domestic hot water.

Local energy production
Walter is suitable for sites where electricity and heat are needed regularly and where suitable wood chips are available.
Local production can increase energy self-sufficiency and complement the site’s existing energy system. Walter can be integrated into the existing electricity and heat production system without requiring the site to operate entirely off-grid.
Key factors affecting suitability include:
- electricity and heat consumption
- seasonal variations in energy demand
- opportunities to utilise the heat produced
- availability and quality of wood chips.
For farms, businesses and energy producers
Walter is suitable for a wide range of applications where electricity and heat can be utilised simultaneously.
Farms
On farms, the electricity produced can be used for on-site consumption, while the heat can be used for production facilities and residential buildings, drying processes or domestic hot water.
The solution is particularly suitable for sites where wood-based raw material is available locally and energy is needed throughout the year.
Businesses and industry
Businesses can use the electricity produced for their own consumption and the heat for buildings or production processes.
CHP production provides the greatest benefit when both the electricity and heat can be utilised efficiently.
Heat entrepreneurs and energy producers
Walter makes it possible to add electricity generation alongside existing heat production. One or more power plant units can be integrated into a larger energy production system.

Read moreHow does Walter generate electricity?
Walter is based on wood gasification:
- Wood chips are gasified.
- The resulting wood gas is treated.
- The wood gas is fed into a gas engine that generates electricity.
- Heat from the engine and the process is recovered for useful purposes.
This allows both electricity and heat to be produced from the same fuel.


Fuel handling as part of the system
The quality, moisture content, storage and feeding of the wood chips all play an important role in reliable power plant operation.
In addition to power plants, Volter provides solutions for wood chip drying, automated feeding and other fuel handling requirements.
Walter or Heizomat?
Walter and Heizomat are designed for different energy needs.
Walter produces both electricity and heat from wood chips.
Heizomat is designed for heat production.
If you need both electricity and heat from the same system, explore Walter. If your requirement is heat production only, Heizomat is a suitable solution.

Volter power plants are used in a wide range of energy production applications around the world.
Planning your own energy production?
The right solution starts with understanding the site’s electricity and heat demand, as well as the available fuel.
When contacting us, useful information includes:
- annual electricity consumption
- annual heat consumption
- electricity and heat consumption profiles
- quantity and quality of available wood chips
- the existing energy system.
We can help you assess whether Walter is suitable for your site and what type of system would best match your energy needs.
