Tolldish Hall Farm Solar – High Voltage Substation Delivery

Providing fully engineered, site-ready power infrastructure for utility-scale solar developments.

Project Overview

B&S Group successfully delivered a High Voltage (HV) substation for the Tolldish Hall Farm Solar project, supporting the development of a renewable energy asset capable of generating up to 25 MW of clean electricity once operational.

Delivered for Ormazabal, specialists in customised and high-tech electrical solutions, the project demonstrates B&S Group’s capability in providing fully engineered, site-ready power infrastructure for utility-scale solar developments.

The Challenge

Utility-scale solar projects require robust, compliant HV infrastructure that can be delivered to tight programme constraints while meeting exacting quality and safety standards. The Tolldish Hall Farm Solar project demanded a substation solution capable of integrating advanced HV switchgear, while ensuring reliability, efficiency, and seamless installation on site.

B&S Group Solution

B&S Group was appointed to deliver a fully engineered HV substation enclosure, designed and fabricated in-house to meet project-specific technical and environmental requirements.

The scope of works included:

Full design and fabrication of the HV substation enclosure
Auxiliary electrical installation and full fit-out
Integration of free-issued HV switchgear, supplied and commissioned by Ormazabal
Delivery, offloading, and placement on site, ensuring readiness for final commissioning

By managing design, fabrication, and integration under one delivery model, B&S Group ensured quality control, reduced installation risk, and supported efficient project execution.

Outcome

Once operational, the Tolldish Hall Farm Solar site will generate up to 25 MW of renewable electricity — enough to power approximately 7,000 homes. The delivered substation provides a reliable and high-performance grid interface, supporting long-term operational stability and compliance.

This project further reinforces B&S Group’s role in enabling the UK’s renewable energy transition through the delivery of engineered power infrastructure built for performance, safety, and longevity.
