Our journey and FY26 highlights

FY26

The infrastructure required to support modern economies is changing at pace. Power networks are expanding, renewable generation is accelerating, digital connectivity continues to grow, and essential utility assets require ongoing investment to meet future demand. OCU operates at the intersection of these long‑term trends, providing the expertise, specialist capabilities and delivery scale required to support critical infrastructure across the asset lifecycle. From Power Transmission & Distribution and water networks to energy transition projects and digital infrastructure, we help clients deliver, maintain and enhance the assets that keep communities connected. Built on a strong foundation of safety, operational excellence and long-standing client relationships, OCU continues to broaden its capabilities, expand its geographic reach and invest in its people, technology and delivery platforms. The milestones highlight key moments in our development and the achievements that shaped FY26.
