Rora Dairy

How is solar powering innovation at an award-winning yoghurt brand?

Middleton of Rora has been farmed by the same family for more than 300 years. As demand for Rora Dairy’s yoghurt has grown, so has the farm’s need for power.

Why did Rora Dairy look to Solar?

Middleton of Rora is a long-established family farm near Peterhead, run by Jane and Bruce Mackie. It supports a 250-strong dairy herd alongside arable crops and has stayed in the same family for generations.

In 2017, the couple launched Rora Dairy, producing simple, pure Scottish yoghurts from the milk of their own free-roaming cows. The brand has grown steadily and electricity demand has grown with it, driven by modern robotic milking systems, refrigeration, processing and packaging. To meet this sustainably, Rora Dairy turned to Forster Group to design a renewable energy solution that would protect the landscape while delivering reliable, low-carbon power.

The Forster Solution

Forster Group worked closely with Rora Dairy to design a system that met the farm’s sustainability goals and the practical demands of a working dairy. The goal was to protect the landscape while delivering dependable, low-carbon power.

The result is a 130kWp ground-mounted array paired with 56kWh battery energy storage system, positioned to sit sensitively within its rural surroundings and to complement the existing farm buildings. Its layout was planned to make the most of on-site generation, and the system has been designed to take battery storage in future.

Peterhead | Completed November 2025

Size: 59 kWp ground mount array

Battery Storage: 56 kWh capacity

Self-consumption of 75%, with excess energy exported back to the grid.

What has solar delivered so far?

The array now generates a significant proportion of the farm’s electricity on site. It powers milking, cooling, yoghurt production and storage with any excess exported back to the grid. With battery storage in place, Rora Dairy can make better use of its own power and the project remains on track for an overall payback of four to five years.

That leaves the farm well placed to keep growing while holding energy costs and emissions steady.
