At the edge of the local grid, power instability threatens both automated equipment and animal welfare. By deploying Wenergy’s all-in-one energy storage system, a modern Dutch dairy farm eliminated outage risks, optimized solar consumption, and unlocked new revenue through smart energy trading.

The Start of This Story

In the Netherlands, a modern dairy farm home to 100 dairy cows and 40 young cattle relies on 24/7 power for two robotic milking systems and a heat pump. Seeking greater self-sufficiency ahead of the Dutch net-metering phase-out, the owner wanted to maximize their 72 rooftop solar panels. Supported by sustainability grants and investment tax deductions, his goal was twofold: safeguard the herd’s daily rhythm and boost energy efficiency.

How was the farm impacted by grid issues before?

Located at the end of the local distribution grid, the farm faced frequent voltage fluctuations and blackouts.

“Being dependent on a single energy stream makes you vulnerable,” Niek, the farm owner, explains.“Cows have a biological clock; if the robot stops, they fall out of their rhythm.”

Traditional diesel generators were ruled out due to high costs (~€7,500), fuel maintenance, and dangerous voltage spikes that could damage sensitive robotics. The farm needed a modern, seamless solution that could guarantee operational continuity without adding extra maintenance or operational risks.

How did the Wenergy system perform in daily operations?

It delivered complete reliability. Wenergy provided a tailored Stars Series 289kWh All-in-One ESS Cabinet, designed to store excess solar energy and instantly take over during grid failures. When the grid drops out, the battery seamlessly powers the farm without delay.

“The battery gives us peace of mind—both in our minds and in the barn,” says Niek. “If the grid drops out, the battery takes over immediately. Sometimes I only hear from my neighbor later that there was a power outage; everything here just kept running.”

How did the system create value beyond backup power?

The system transformed energy management. Stored solar power runs the robots and heat pump during high-demand hours, while intelligent software trades electricity based on market prices.

“The battery is configured so that we charge during low-price hours and run on our own energy during expensive hours; whatever is left over, we trade,” Niek notes.

Between energy savings, power trading, tax incentives, and avoiding generator maintenance, the financial math clicked perfectly.

Any advice for other farmers considering energy storage?

For Niek, investing in a tailored battery storage system was a clear win for the farm’s future. By replacing single-grid dependency with intelligent backup power and smart energy trading, farmers can protect their livestock, shield sensitive machinery, and turn energy costs into a long-term profitable asset.
