The challenge: How to manage the material flows in a pellet plant

Pellet 4Energia, owned by Enefit Green that is part of Eesti Energia, is a factory that manufactures heating pellets. The production facility consists of a wood pellet plant and a woodchip cogeneration plant that generates heat and electricity. Pellet 4Energia handles large quantities of different forestry materials from sawdust to timber, and the continuous and smooth operation of the plant requires control of these material flows. Pellet 4Energia is one of the largest manufacturers of renewable energy in the Baltic countries.

The plant was commissioned in Brocēni, Latvia, in 2017.

The solution: Automated load registration and data collection with Once

The Once by Pinja system was commissioned immediately when the production plant was established. The plant’s CHP Manager Juris Aprups explains that he first became acquainted with Once in his previous post at Fortum.

– We knew that we needed a system for load registration, and we did not really find any other good alternatives. Once is quick and easy to use. The registration process is automated, so the drivers can do it themselves. All in all, our company has almost 20 Once users, says Juris Aprups.

Many types of material flows pass through the two plants. The most important materials are wood chips, timber, and sawdust. Moreover, the used diesel fuel is also weighed and registered. Finally, the ash resulting from the burning process is weighed. Once provides assistance with all the processes.

– I monitor the load reports on a weekly and monthly basis and use them in production reporting. Through Once, I can even use the fuel analyses provided by the laboratory. My colleagues also use the reports produced by Once in matters related to their individual responsibilities, Aprups explains.

Pellet 4Energia has almost 50 material suppliers. Once helps the company to manage the operational entity. The system shows how the suppliers meet their contractual obligations in terms of, for example, volumes and the quality of biomass fuel. The system is used in both bookkeeping and laboratory operations.

– With the information provided by Once, we can identify each load quickly and accurately and detect potential problems, says Aprups. According to Aprups, the plant receives all the necessary information from the reports provided by Once. New reports can be requested, if need be.

– The level of technical support has been great. Right in the early days, I had problems with the system connections, but the support service provided me with speedy assistance. I have nothing negative to say, as every single question has been answered. Without a well-functioning tech support, it is impossible to fully benefit from these kinds of systems, summarises Aprups.
