Engineering consultants for energy and sustainability
Independent advice. Director-led delivery. We work with utilities, government agencies, the mining industry, and developers across Australia.
Summation is an Australian engineering and advisory consultancy. We provide technical advice and engineering design across energy, renewables, and sustainability — from feasibility studies and grid connection approvals to detailed design, owner's engineer services, and sustainability certifications.
Our clients include utilities, government departments, mining companies, commercial property owners, and renewable energy developers. What they share is a need for technical advice they can trust and an engineer who gives them a straight answer.
Every project is led by a director or principal. Clients work directly with the people who carry the expertise.
How we work
Independent advice - We have no commercial relationship with any contractor, equipment supplier, or financier. Our advice reflects what is right for the project.
Director-led delivery - Every project is led by a Director or Chartered Professional Engineer. Clients work directly with the people who carry the expertise.
Plain English - Energy and sustainability problems are often technically complex. We explain what we find clearly, so clients can make informed decisions rather than taking advice on faith.

Director, Energy
P: 0466 716 216“I came to engineering through the trades, which means I've always approached problems from the perspective of how something actually gets built — not just how it looks on paper. That background informs everything I do..”

Associate, Senior Energy & Sustainability Engineer
P: 0450 914 238“My background is engineering and economics together. I find that the most useful thing I can do for a client is connect the technical analysis to the financial case — so they understand not just what the numbers mean, but what to do with them.”
