The project was delivered for a small pulp and paper processing company producing disposable napkins, paper towels, and hygiene paper products. The primary objectives were to reduce electricity costs and ensure stable operation of production equipment during grid outages, without disrupting technological processes or exporting power to the grid.
Solution Delivered
- Full reconstruction of the main electrical switchboard
- Installation of a custom-built Automatic Transfer Switch (ATS)
- Integration of an existing 100 kW diesel generator into the ATS system
- Installation of a 100 kW rooftop solar power plant
- Grid-tied inverter: Deye
- Configuration of zero-export mode, limiting solar generation strictly to on-site consumption
- Turnkey EPC delivery: design, installation, commissioning
Results
Within the first 10 days of operation, the solar power plant generated 1.73 MWh, covering 62% of the facility’s total electricity consumption – without exporting energy to the grid.
In the event of a grid outage, backup power is activated automatically via the ATS system in combination with the 100 kW diesel generator, ensuring uninterrupted production.
