What we do

Targeted solutions

Some projects need a design that’s simply good: fit-for purpose, cost-efficient, built for a specified life. Others call for great — a project that breaks new ground. Rayo’s engineering teams know the difference, because we listen, innovate, then bring your vision to life.

Further, Rayo has seized the opportunity to offer our clients certainty from design through to delivery by having this engineering capability fully in-house. Ready availability of engineering inputs flowing into project delivery eliminates costly delays by enabling timely design clarifications, rectifications and quality control throughout.

Our engineering team collectively has decades of experience in the design, development and delivery of complex renewable energy and utilities projects, enabling us to deliver with excellence, quality and efficiency.

Full project lifecycle expertise

Rayo’s end-to-end engineering services ensure project success from conception to completion. Our capabilities span the project lifecycle:

  • Concept and detailed design: Innovative and efficient, extending to a wide range of infrastructure assets.
  • Engineering studies: Rigorous analysis supporting decision making and managing risk.
  • Construction engineering support: Ongoing engineering support throughout, ensuring quality and compliance.
  • Commissioning and system verification: Ensuring systems are fully operational and meet client specifications.

Specialised energy infrastructure

Our energy infrastructure engineering solutions encompass:

  • High voltage (HV) systems: Design, maintenance and testing
  • Battery energy storage systems (BESS): To any scale, from concept to commissioning
  • Renewable energy: Large-scale solar and wind farms, including grid integration and storage systems
  • Energy transmission and distribution: Design, testing and optimising transmission lines and substations.

Advanced testing and inspection

Testing and inspection services ensure energy infrastructure meets the highest standards:

  • HV testing: Dielectric dissipation factor testing, partial discharge, insulation resistance and VLF testing
  • Commissioning testing: Factory and site acceptance testing, and protection system verification
  • Asset condition monitoring: Ongoing monitoring services to assess infrastructure health and ensure reliability.

Solutions to complex challenges

Rayo couples technical nous and cutting edge technology to deliver solutions that meet complex engineering challenges, with in-house design expertise across:

  • Automation (SCADA): Real-time control and monitoring of energy systems
  • Earthing and protection: Design and implementation of reliable protection and earthing systems to ensure system stability and safety.
  • Connection agreements: Managing the complex regulatory processes for network connections, ensuring smooth integration into the grid.

Safety and environmental commitment

At Rayo, safety and the environment are at the forefront by design.

We are ISO 9001, ISO 14001, ISO 45001 certified, WorkCover accredited and environmentally conscious. Our rigorous Safety in Design processes identify and mitigate potential hazards from the outset, ensuring safe and environmentally-sound project delivery.
