Powersystems has successfully energised the Camster II Wind Farm, marking another significant milestone in the UK’s transition to a sustainable, low-carbon energy system.
Located off the A882 near Haster, Wick in the Scottish Highlands, Camster II has been developed by RWE Renewables UK Onshore Wind Limited, with Farrans Construction acting as Principal Contractor and Powersystems delivering the full Electrical Balance of Plant (EBoP) package.
With an installed capacity of 36 MW, the project comprises 10 × Vestas 3.6 MW turbines, generating clean electricity at 33 kV for export to the Scottish & Southern Electricity Networks Distribution (SHEPD) network — enough renewable energy to power approximately 40,000 homes annually.
Camster II expands the existing Camster Wind Farm following Scottish Government consent, strengthening renewable generation capacity in the Highlands and reinforcing regional grid resilience.
On 18 December 2025, Powersystems successfully energised:
- The 33 kV wind farm switchgear
- The auxiliary transformer
- The full 33 kV array network
Powering the Transition to Net Zero
Onshore wind remains the backbone of Scotland’s renewable energy mix. As of 2025, the UK has over 15 GW of installed onshore wind capacity, with Scotland contributing the majority of this generation. Onshore wind is one of the most cost-effective and carbon-efficient forms of electricity production, playing a critical role in delivering the UK’s legally binding net-zero targets.
Camster II contributes:
- 36 MW of zero-carbon generation
- Displacement of thousands of tonnes of CO₂ annually
- Increased security of supply for the north of Scotland
- Long-term, stable renewable infrastructure for decades to come
For Powersystems, this project directly supports our mission of “Powering the transition to a sustainable future” — delivering grid-ready infrastructure that enables renewable generation to connect safely, efficiently and reliably.
Scope of Works – Summary
Powersystems was appointed as Electrical Balance of Plant (EBoP) contractor for Camster II Wind Farm, delivering the complete high-voltage and low-voltage electrical infrastructure required to connect the 36 MW development safely and compliantly to the 33 kV distribution network.
Our scope encompassed the design, installation, testing, commissioning and energisation of the wind farm’s electrical systems, including:
- Construction and fit-out of the 33 kV wind farm substation
- Installation of the 33 kV switchgear and auxiliary transformer
- Delivery of the 33 kV array cable network linking all 10 turbines
- Protection, control and SCADA systems integration
- Earthing systems for the substation and wind turbine generators
- Full compliance studies and grid-code assurance
- HV/LV commissioning and supervised energisation
The works were delivered in close coordination with the developer, principal contractor and DNO, ensuring a safe, efficient and grid-compliant connection that now enables Camster II to export renewable energy into the Scottish network.
Delivering Sustainable Infrastructure
Sustainability was embedded throughout delivery:
- Efficient cable sizing and loss optimisation
- Modern protection systems enhancing operational reliability
- Low-impact substation design
- Environmentally conscious installation practices
- Long-life asset design supporting a 25-year operational lifespan
Beyond carbon reduction, Camster II delivers long-term economic and social value:
- A community benefit fund supporting local initiatives
- Approximately 500 jobs supported across Scotland (including 150 in the north)
- Strengthened regional supply chains
- Skills development within the renewable energy sector
Strengthening Long-Term Partnerships
Camster II represents another successful collaboration between Powersystems, Farrans Construction and RWE Renewables.
As the UK’s leading HV connection provider to the wind industry — having connected over 24% of UK wind generation sites — Powersystems continues to play a central role in enabling renewable energy projects nationwide.
The Result
The Camster II EBoP works were completed safely, on budget and in line with the revised programme. The site is now fully energised and contributing to Scotland’s expanding renewable energy portfolio.
Every connection we deliver strengthens the UK grid and accelerates the journey toward a cleaner, more resilient energy system.
