Most people have no idea where their electricity came from five minutes ago. The grid is a murky pool, and the best proof of green power a company usually gets is a certificate purchased months after the fact, covering a whole year in one vague lump. Steve Hoy, a former IBM smart-grid analyst, thinks that’s like balancing your books once a year and calling it financial management.
His Sydney-based startup, Enosi, sells a piece of software called Powertracer. It does one thing, relentlessly: it traces electrons from a specific wind farm or solar array to a specific meter, in five-minute intervals, all day, every day [f6s.com]. For retailers and large energy users, it’s the difference between claiming you use renewable energy and proving, in near real time, exactly when you did.
The 24/7 accountability layer
The bet is that granularity creates value. Today’s dominant system, Renewable Energy Certificates (RECs), operates on an annual matching basis. A data center buys enough certificates to cover its total yearly consumption, but that says nothing about whether it was powered by coal at midnight or sun at noon. Enosi’s platform, which integrates directly into retailer billing systems, makes that mismatch visible [Australian Financial Review, September 2026].
The practical effect is two-fold. For a corporate buyer like Google,which is piloting the technology at its Sydney campus,it enables genuine 24/7 carbon-free energy tracking, a mounting priority for tech giants [Google to trace clean energy use with Enosi - Energy Source & Distribution, 2026]. For a retailer, it allows for novel products, like Enosi’s Virtual Net Metering. This lets a business with one large solar array, like a Woolworths distribution centre, allocate that power in near real time to offset consumption at other, nearby sites that lack panels [Powertracer, enosi, 2026].
Wiring into the Australian grid
Traction, in this business, is measured by integrations. Software is worthless if it doesn’t plug into the complex, legacy systems of energy retailers. Enosi first trialled its platform with Energy Locals in New South Wales back in 2019 [Enosi’s Powertracer 2.0 platform goes live, 2026]. The company now reports deals with five Australian electricity retailers to embed Powertracer into their metering and billing operations [Energy traceability cleantech Enosi closes $1.48 million capital raise - pv magazine Australia, 2026].
That footprint provided the foundation for the more ambitious enterprise work. The Woolworths VNM deal went live in August 2024, and the Google pilot represents a crucial stamp of technical credibility. The company has been funded to pursue this wedge, raising a $1.48 million seed round in October 2021 from investors including ReNu Energy and Energy Estate [Tracxn].
| Round | Date | Amount | Lead Investor(s) |
|---|---|---|---|
| Grant | August 2020 | $345,000 | Unknown [PitchBook] |
| Seed | October 2021 | $1,480,000 | ReNu Energy, Energy Estate, Artesian [Tracxn] |
The team betting on data over hardware
The founding trio brings a mix of grid analytics and commercial energy experience. CEO Steve Hoy cut his teeth on smart-grid systems at IBM [The Fifth Estate, August 2018]. COO Bill Barden has a background in energy and utilities, while Grant McDowell heads strategy and product [f6s.com]. They are not building solar farms or batteries. Their use is data, and their tool is cryptographic validation to create an auditable ledger of energy transactions [Awesense, 2026].
The path is classic B2B software: land the retailers to enable the use cases, then let those use cases attract the large corporates with the deepest pockets and the strongest sustainability mandates. It’s a land-and-expand motion within the energy sector itself.
Where the meter could stop
The ambition is clear, but the obstacles are wired directly into the infrastructure Enosi is trying to instrument. The company’s success hinges on a few critical, unproven steps at its current scale.
- The retailer bottleneck. Every new market requires fresh, arduous integrations with local utilities and retailers. While Enosi has five Australian partners, expanding to regions with fragmented grids or resistant incumbents could slow growth dramatically.
- The premium puzzle. It remains to be seen how much retailers or end customers will pay for this granular traceability. The value is clear for a Google, but will a mid-sized manufacturer see enough ROI to switch providers or pay a premium tariff?
- The competitive horizon. Enosi is not alone. European players like FlexiDAO also offer granular energy tracking, and large incumbent software vendors could bundle similar features. Enosi’s first-mover integration work in Australia is an asset, but not a permanent moat.
The company’s answer, for now, is to go deep rather than broad. Dominate the Australian market, prove the economic model with flagship deployments like Woolworths and Google, and use that case study to fund the next geographic leap.
For a climate tech reporter, the unit economics of traceability are fascinating. Consider a single, large supermarket store using 1,000 MWh per year. Under an annual REC system, its green claim is a blunt instrument. With five-minute matching, if it can shift just 10% of its load to sunny afternoon hours through demand response or onsite solar, it materially changes the carbon content of its operation. That’s 100 MWh of genuinely clean energy, verified, versus 1,000 MWh of annualized guesswork. The difference isn’t just moral; it’s a measurable delta in tons of CO2 that could soon carry a price tag.
Enosi’s real competition isn’t another startup. It’s the inertia of the annual certificate, a system that has let everyone feel good without having to look too closely. To win, Hoy and his team don’t need to build a new grid. They just need to make the old one finally show its work.
