Closedout is a specialist completion and commissioning practice for high-voltage substation and renewable energy projects. We solve the problem that derails more projects than any other: the final 20%.
The construction phase is well-resourced, well-managed, and well-understood. It's the completion phase — commissioning, energisation, handover — where projects fall apart. Every time.
The sequence isn't locked, protection testing is compressed, and the network operator approval is nowhere near ready.
Thousands of defect items, no clear ownership, and subcontractors who've already demobilised.
As-built records are incomplete. The network operator won't approve energisation. The date moves again.
PPA start dates, debt drawdown conditions, connection windows — all at risk from a completion process no one owns.
The Closedout Method
Built from 40 years of HV construction experience, the Closedout Method treats the final phase as a discipline — not an afterthought. Five structured steps that take your project from construction complete to energised, handed over, and done.
A dedicated completion programme — separate to the construction programme — that sequences every commissioning activity, documentation milestone, and approval requirement with realistic lead times and clear ownership.
Early engagement with the network operator (Powerlink, Transgrid, or relevant NSP) to agree the energisation sequence and document requirements — months before you need them, not weeks.
As-built records updated in real time throughout construction — not chased down at the end. Turnover packs and handover documentation that are ready when you need them.
Clear close-out scopes for every subcontractor, with agreed completion dates and interface ownership at every trade boundary. No gaps. No ambiguity.
A structured handover process that brings the client's operations team in early, manages the commissioning hold points systematically, and delivers energisation on time — cleanly.

Who's behind Closedout
I've spent 40 years building high-voltage substations and energy infrastructure. And in that time, I kept seeing the same thing: spectacular projects, great teams, solid construction — and then the wheels fall off in the final stage.
Commissioning gets compressed. The completion sequence is a mess. Energisation gets pushed back six months. The whole project finishes under a cloud.
"The projects that get to energisation on time have one thing in common: they treat completion as a phase in its own right — not something that happens naturally at the end."
I built Closedout because the completion and commissioning phase of HV and renewable projects deserves the same discipline as the construction phase. That's all we do. And after 40 years, we know exactly how to do it.
Gary Stachurski
Founder, Closedout | Licensed Electrician | HV Completions Specialist
Gary's completions systems transformed how we approached handover on Clarke Creek. The documentation discipline he established from day one made the difference between a clean energisation and the chaos we'd seen on previous projects.
The level of QA and completions management Gary brought to Greenough River was unlike anything we'd worked with before. His structured approach to turnover and handover gave us confidence throughout the final phase.
