Our clients are both network owners, such as transmission and distribution utilities, and network users, such as generators, electricity consumers and rail network operators.

We focus on system reliability through asset management, system renewal and asset whole-of-life program development, which is dedicated to managing the performance of the aging T&D infrastructure.

Our T&D team is active in realizing a 21st century energy grid economy that is founded on comprehensive utilization of renewable energy, distributed generation and demand-side participation. We help fulfill the promise of a sustainable future through lowering the carbon emissions of the power sector.

A synergy between technical and economic skills. An added value for electric utilities.

With more than 90 years of experience, AECOM works with more than 300 power utilities in over 50 countries around the world.

We are a world leader in the provision of environmental and engineering services for power transmission and distribution (T&D) infrastructure.

Our team of engineers, planners and environmental specialists provides a full set of services required within the electricity supply industry. We specialize in environment and property services, institutional reform and development, strategic planning, power systems analysis, power quality, project feasibility development, detailed design and construction supervision for networks of national scale and for all system voltages up to 800 kV.
