Development

With extensive experience across the entire energy project lifecycle, Rayo expertly navigates every phase—from land acquisition and grid connection to technology selection, EPC tendering, and contract negotiation. Our proven track record ensures efficient, cost-effective, and transparent development processes, supporting projects seamlessly through to financial close.

Engineering

Rayo’s electrical and civil engineering teams have a ‘sense of occasion’. We know when our clients simply want a ‘good’ design solution’ – fit-for-purpose, cost-efficient and designed for a specified life – and when you want to move beyond good to ‘great’ with a project that breaks new ground. We know because we listen, innovate, then bring your vision to life.

Construction

The Rayo construction team will procure, construct and commission your project agilely, efficiently and to the highest standards. We offer a construction capability that has driven the successful delivery of some of Australia’s highest profile utilities, energy, and renewables sector projects. We thrive on getting these complex, large-scale infrastructure projects across the line.

Services

Rayo delivers a full suite of services to maintain and optimise energy infrastructure assets, from substations and transmission lines to large-scale projects such as wind farms, solar farms, mining sites and Defence facilities.
