Domat/Ems wood chip power plant

About the project

AXPO Tegra operates Switzerland's largest wood-fired power plant in Domat/Ems, ensuring sustainable and climate-friendly energy production, a secure and independent power supply, and high regional added value. The company's core competencies include the production of renewable energies and the drying of various wood products.

As part of this automation project, Rey Technology recently developed a central control system for AXPO Tegra's wood chip power plant. The scope of the project ranged from the operation and monitoring of the power plants and the drying plant to remote alarm systems. All areas of the plants can now be coordinated and monitored uniformly in the central control room. Various clients with up to four screens are available to the customer for this purpose. The range of functions is rounded off by remote alarm notification via the Zenon control system.

The developers at Rey Technology planned and implemented the replacement of the existing systems with a Zenon control system. In addition to the delivery and installation of two redundant server racks, this also included the development of the new Zenon HMI application. The existing applications served as a template. This affected the following components:

• 2x Rockwell Factory Talk View stations
• 1x ProLite station
• 1x older Zenon version
• 2x WinCC touch panels

The contribution of Rey Technology

AXPO Tegra's power plants can now be monitored and controlled centrally and uniformly. This simplifies processes while also increasing safety. In addition, several outdated components were replaced, ensuring the future performance of the control system. As Rey Automation's typical can-do mentality also came into play in this project, the customer also benefited from an efficient and targeted planning and implementation phase. Tailored to the existing applications of the control system, Rey Technology used various components whose performance has already proven itself in various projects.

Advantages for the customer

• Central monitoring of all plant areas from a control room
• Standardization of control systems through the integration of various technologies
• Increased operational reliability through the replacement of outdated components
