Engineers, financiers and operators of Australia's energy transition.
ESQ Energy Solutions designs, finances and operates commercial-scale solar, storage, EV charging and grid infrastructure. Headquartered in Brisbane, we serve clients across every state and territory.
Australia has the best solar resource on Earth and one of the most ambitious decarbonisation programs in the OECD. The constraint isn't ambition — it's engineering rigour, capital sequencing and operational discipline.
ESQ exists to industrialise that work. We engineer the system, structure the finance, manage the network connection and operate the asset for its full service life. One accountable partner from feasibility through to 25-year O&M.
Smart solutions. Sustainable future.
How we operate.
Engineering rigour
Electrical and structural design work is carried out by licensed, CEC-accredited contractors, with RPEQ sign-off engaged per project where required.
Capital alignment
We invest alongside clients via PPAs and BOOT structures. Our returns depend on the asset performing as engineered.
25-year accountability
We operate what we build. ESQ guarantees performance and availability over the asset's full life — measured monthly, reported quarterly.
A single accountable partner across hardware, install and operations.
