VIVO Defence Services upgrade
Duke of Gloucester Barracks
VIVO Defence Services, responsible for maintaining and upgrading facilities across the UK Defence estate, required a sustainable and cost-effective solution for lighting internal roadways and pathways at the Duke of Gloucester Barracks.
The existing mains-powered streetlights and bollards were failing, creating safety risks for personnel and visitors. Vivo sought an alternative that would eliminate costly cable trenching, reduce ongoing maintenance and support the Ministry of Defence’s (MOD) sustainability goals.
Challenges
- Ageing infrastructure: Traditional mains-powered street lighting and bollards were no longer reliable.
- Complex underground services: Large numbers of buried utilities made trenching and cabling impractical and potentially hazardous.
- Safety & security needs: The site required consistent, dependable lighting to maintain a safe environment for military personnel and visitors.
- Sustainability targets: Vivo needed an off-grid solution that aligned with the MOD’s net zero ambitions.
The Solution
Following a successful tender process, Prolectric was contracted to deliver a fully off-grid lighting upgrade. The installation included:
- AE6 Solar Street Lights (x177) – providing powerful, reliable illumination for internal roadways and key access routes.
- ProTemp Solar Tower Light (x1) – selected to illuminate an area where buried services prevented safe excavation, offering a “no-dig” lighting solution.
- Solar ST Bollards (x10) – ensuring safe pedestrian pathways with uniform lighting and zero cabling.
Our team also carried out the safe removal of existing mains-powered columns, delivering a complete installation service with robust RAMS to support safety and compliance on-site.
Results
The project has transformed lighting at Duke of Gloucester Barracks, by adopting Prolectric’s solar lighting solutions, VIVO achieved:
- Off-grid reliability – Solar-powered units operate independently, removing reliance on underground cabling.
- Health & Safety improvements – Reduced excavation work meant no risk of damaging buried services, improving site safety during installation and long-term operation.
- Future-proofing – Maintenance-free LED lighting with built-in smart controls ensures long-term performance and reduced operational burden.
- Cost savings – The annual electricity cost savings equate to £9,934, this doesn’t take into consideration the savings made through no trenching/cabling requirements and not needing a grid connection.
- Carbon savings – 6,599 kg of CO2e – annual emissions reduction compared to mains-powered lighting.
