Dairy Processing Plant Peak Load Management
This project features a distributed energy storage cabinet installed at a dairy processing plant to address high electricity demand charges and provide grid support. The all-in-one cabinet, integrating PCS, battery, and control system, operates primarily in grid-connected mode. Its dual functions are to shave peak power demand during the plant's intensive milk processing cycles and to participate in the local distribution network's frequency regulation services.
Location:Groningen, Netherlands
System:125kW/261kWH outdoor cabinet
To maximize economic return and grid support, the system executes an intelligent daily strategy:
Scheduled Peak Shaving (PQ Mode): The system predicts the plant's load profile and discharges predictively during the evening peak processing window (6 PM - 10 PM). This effectively caps the plant's power draw from the grid, avoiding costly demand charges.
Automatic Frequency Regulation (PQ Mode): Outside of peak shaving periods, the cabinet remains on standby, continuously monitoring grid frequency. It automatically responds to frequency deviations by injecting or absorbing active power as required, earning additional revenue from the network operator.
System Topology & Advantages:
The integrated "cabinet" topology offers a plug-and-play solution with a minimal footprint, ideal for space-constrained industrial sites. Its core advantage is the seamless blending of energy arbitrage and grid service functionalities through intelligent energy management software.
The system delivers tangible financial benefits by directly reducing the plant's highest electricity costs (demand charges). Simultaneously, it creates a new revenue stream by providing a fast-responding frequency regulation resource to the grid, significantly improving the project's return on investment. This dual-income approach makes distributed storage a highly attractive proposition for medium-sized commercial and industrial customers.
