Agriculture Case Study

Rora Dairy Case Study

Rora Dairy

Peterhead

Middleton of Rora, partnered with Forster Group to install a 130kWp ground-mounted solar array and 56 kWh battery storage system to power its growing Rora Dairy operation, home to one of Scotland's premium natural yoghurt brands.

The Challenge

As the business has grown, so too has its energy demand, driven by modern robotic milking systems, refrigeration, processing and packaging. To meet this sustainably, Rora turned to Forster Group to design a renewable energy solution that would protect the landscape while delivering reliable, low-carbon power.

Our Solution

The resulting 130kWp ground-mounted and battery storage system was designed to sit within its rural surroundings, complementing existing farm buildings and maximising on-site generation. The new solar array now generates a significant proportion of the farm’s electricity on site, powering everything from milking and cooling to yoghurt production and storage.

The Challenge

Running a busy working farm alongside a collection of luxury lodges creates significant energy demands throughout the year. As energy prices continued to rise, increasing electricity costs placed growing pressure on the long-term sustainability of the business.

“As a family-run business with strong farming roots, we’ve always been very conscious of our environmental impact. Like many others, we’ve seen energy costs rise."

-Claire Picken, Manager

Our Solution

The bespoke ground-mount 37.38kWp installation was designed to power both the working farm and luxury lodges efficiently. The system integrates seamlessly within the rural setting, maintaining the site’s visual appeal while enabled long-term carbon reduction and operational savings to support sustainable growth

"We had a great experience working with Forster Group. They were professional, informative and flexible, which was essential for balancing a major installation with the day-to-day running of a working farm and luxury retreat."

Humbie Farm Case Study

Humbie Mains Farm

West Lothian

Since the 72 kWp installation, Humbie Farm has significantly reduced its dependency on the national grid, successfully bucking the trend of soaring energy prices. The farm has even been able to turn sunny days into profit by selling excess energy back to the grid.

The Challenge

Landowner of Humbie Farm, Andrew Bayne-Jardine decided it was time to take control of soaring energy prices. Nestled in the West Lothian, Humbie farm is a traditional arable operation with substantial energy demands- from daily farming activity to household use of a ground source heat pump, an AGA, and two electric vehicles. Frustrated by rising energy costs, Andrew turned to Forster Group in 2023.

“Solar was something we’d been thinking about for a while, but the spiralling costs of electricity were the final push. I couldn’t see prices falling anytime soon, and solar offered a practical, sustainable solution.”

-Andrew Bayne-Jardine, Landowner

kWp

Ground-Mount Solar

Our Solution

A 72.72 kWp ground-mounted solar PV system. Drawing on decades of expertise in agricultural and commercial installations, Forster Group designed a tailored system to meet Humbie Farm’s daily energy needs, while considering future growth

Outcome

Since the installation, the results have exceeded expectations. The system is outperforming projections and has significantly reduced the farms reliance on the national grid. The energy generated comfortably covers the household’s spring and summer demand, with a surplus credit helping to offset lower out in the winter months.

Andrew has also secured a contract for exporting surplus power and thanks to the size of the installation, Humbie Farm has the potential to generate up to £12,000 per year from selling electricity back to the grid.

"

“We’ve only had a couple of small electricity bills during winter, I used to worry about our energy bills constantly - now I have another reason to celebrate when the sun shines on Humbie Farm. It’s effortless income.”
