Core capabilities

UGL is a major player delivering a full range of engineering design, procurement, construction and operations and maintenance services of solar farms across Australia. We have installed over 800MWp of capacity across 13 solar farms. 

We are proud to have provided the engineering design and construction of batteries across Australia as well as one of the world’s largest lithium-ion batteries at the Victorian Big Battery.

We are currently involved in several large-scale wind farm balance of plant tenders in joint venture with CIMIC Group sister company, CPB Contractors.

UGL’s capabilities extend across the hydrogen value chain. We participate in feasibility and front-end engineering design all the way through to construction, delivery and operations and maintenance.

UGL's clients benefit from new energy’s dedicated operations and maintenance (O&M) team. UGL O&M has proven success in managing solar farms on behalf of our clients, delivering services such as:

  • site safety, environment, operations and security management 
  • generation performance management
  • generation availability management
  • scheduled and unscheduled maintenance and repairs
  • compliance with the Generator Connection Agreement, NER and Operating Protocol
  • network service provider interaction
  • vendor warranty management
  • spare parts management
  • generation, OpEx and facility reporting
  • off-site engineering and management support
  • alternative land maintenance options, including sheep grazing.

UGL has successfully completed O&M service contracts for 6 solar farms across Australia, including 2 extended contracts.



UGL's O&M team of engineers, supervisors and management is spread throughout Australia, allowing better response across time zones and reducing deployment times.

The team leverages our broader professional expertise within new energy and across the wider business. This allows access to a breadth of knowledge and experience to respond to faults, whilst maintaining efficiencies and without requiring external support.

At UGL, we also have a focus on the local community of each project. Where possible, we champion local employment and provide opportunities to local suppliers.

Operational safety & strategy

Operational safety & strategy

The UGL O&M team focuses on the development and alignment of workplace health and safety plans, ensuring relevance to the hazards and risks of each individual site.

We prioritise safe operation with maintenance strategy, ensuring a client’s site generation performance and availability is optimised. Automated monitoring systems, trend analysis, and a long-term data set across multiple sites and assets drives this optimisation.

Our team works closely with local stakeholders, in collaboration with clients to support alternate maintenance strategies, including the use of sheep for ground maintenance and community education centres for training and site tours.
