Beavertown Brewery HV/LV Upgrade Case Study
Download the full Beavertown Brewery Case Study to see how Powersystems delivered a new 2000 kVA HV/LV supply to support one of the UK’s fastest‑growing craft breweries. The PDF provides a clear overview of our transformer installation, high‑level LV cable route design, HV isolation solution and full electrical integration—completed safely and efficiently within a live industrial environment. Ideal for engineers, project managers and commercial operators seeking deeper insight into a high‑capacity electrical upgrade that enabled Beavertown’s continued expansion.
Client Background
Beavertown Brewery is one of the UK’s fastest‑growing craft breweries, known for leading London’s beer renaissance with bold, modern, American‑influenced styles. The brewery has grown rapidly, moving site four times in its early years before expanding into major new production facilities.
In 2018, Heineken N.V acquired a minority stake to support a £40 million expansion, enabling a ten‑fold production increase and the creation of a new visitor site. Alongside this, Beavertown partnered with Tottenham Hotspur to open a microbrewery and taproom at the club’s new stadium — a UK Premier League first.
Supporting this exponential growth required a significant electrical infrastructure upgrade capable of delivering safe, reliable, high‑capacity power to the expanding brewery.
The Challenge
Beavertown required a major increase in electrical capacity to power new production lines, expanded brewing operations and future site development. Key challenges included:
- Integrating a large‑capacity 2000 kVA HV/LV transformer
- Maintaining safe isolation without needing DNO attendance
- Installing large LV circuits within a confined, operational environment
- Ensuring pedestrian access beneath the cable routes
- Designing circuits to accommodate high current loads approaching 3000 A
The brewery needed this upgrade completed quickly to support production timelines ahead of major expansion milestones.
Our Engineering Solution
Powersystems designed and delivered a high‑capacity HV/LV supply solution, centred around:
- A 2000 kVA cast resin transformer delivering nearly 3000 A
- An 11 kV isolator switch to allow the client to isolate and earth their supply without DNO involvement
- HV circuit breaker and LV connection box
- A 2‑tier cable ladder system (900 mm wide), installed 3 m above floor level to retain pedestrian access
The transformer was delivered as a composite unit, factory‑coupled with the 11 kV disconnector — ensuring a compact footprint and simplified installation.
LV Cable Design
Each LV circuit comprised:
- 17 × 500 mm² single‑core cables per set
- 4 cables per phase
- 4 neutral cables
- 1 earth cable
The design accounted for cable de‑rating, physical separation of generator and feeder circuits, and full integration with a restricted earth fault (REF) protection scheme.
Project Process
- HV/LV design development by Powersystems’ in‑house engineers
- Factory integration of transformer and HV isolator
- Cable route design and installation of high‑level bridge system
- Installation of LV connection box and generator cabling
- Full testing and commissioning of HV protection, transformer and LV circuits
- Final integration with brewery electrical systems
- Handover to client ahead of production ramp‑up

Key Risks & Mitigations
- High‑current LV circuits – Mitigation: Detailed de‑rating calculations, REF protection, careful separation of circuits.
- Cable routing above pedestrian areas – Mitigation: 2‑tier high‑level ladder system at 3 m to maintain safe access.
- Transformer/isolation design constraints – Mitigation: Factory‑coupled HV disconnector eliminating need for DNO attendance.
- Tight programme for production milestones – Mitigation: Accelerated installation and commissioning schedule.
Environmental Considerations

- Compact composite transformer design reduced installation footprint
- High‑level cable routes minimised civil modifications
- Cast resin transformer reduces risk of oil‑related environmental impact
- Efficient LV design reduces long‑term power losses
Economic & Operational Benefits

- Increased electrical capacity supports brewery expansion
- Client gains full control over HV isolation, reducing ongoing operational costs
- High‑capacity supply enables future production growth
- Infrastructure aligns with long‑term business scaling plans
Future Prospects
With the upgraded HV/LV infrastructure in place, Beavertown Brewery is positioned to continue its rapid growth, supported by robust and scalable electrical capacity.
