Western Australia · a local briefing
Zenith already wires up a few new suburbs and one industrial park, instead of waiting for the big network to do it. This page sorts everyone we found by how much they resemble those jobs.
Bigger is not better. A company building 4,000 homes is often too big for one contract. A company building three townhouses is too small to bother. The useful ones look like the projects below.
These are real projects, already public. Everything else on this page is judged against them.
Homes
EglintonCedar Woods. About 1,300 homes. 4.4 MW of rooftop solar and a 5 MW system. Zenith is building it.
Marina
Ocean ReefDevelopmentWA. About 1,000 homes and shops. A 4 MVA connection. Zenith is building it.
Industry
PeelDevelopmentWA. An industrial park south of Perth. It started at 2.2 MW. Zenith runs it.
One contract has a ceiling. Under 10 MW of connection, no more than 10 MW of solar and batteries, about 5 MW of actual use, and about 4 MW of contracted demand. The power network’s own planning lump is the next size up: about 1,600 homes, 75 hectares, or 15 MVA. MVA and MW are both ways of saying how much electricity. For this page, treat them as the same yardstick.
Start here
Two organisations. They are not guesses. Their names are on Zenith’s own project pages.
Eglinton
About 1,300 homes, with 4.4 MW of rooftop solar and a 5 MW local system. Zenith is already building this one. It is the clearest example of the size that fits.
Ocean Reef and Peel
The state land agency. Ocean Reef is about 1,000 homes on a 4 MVA connection. Peel is an industrial park that started at 2.2 MW. They also sell much larger estates, so not every project of theirs is one contract.
Closest match
A public page gives a size, and that size sits in the same neighbourhood as the jobs above: a few hundred to about 2,000 homes, or roughly 15 to 75 hectares.
Allara, Eglinton
About 1,688 homes. That sits on the 1,600-home line used for planning the power network.
Beenyup Grove
469 house lots. Smaller than Eglinton, and still a whole stage of a suburb rather than a few houses.
Samara, Casuarina
60 hectares of shops, warehouses and houses, close to the 75-hectare planning mark. A Costco is named as one future user.
Offer a stage
These are the right kind of estate. Taking the whole thing in one go would sit above the 10 MW ceiling. A stage of the estate can still fit.
Golden Bay
About 2,200 homes. A stage of this could fit. The whole estate is more than one connection.
Amberton, Eglinton
About 2,686 homes on the largest mapped piece, plus another piece of about 765. Same idea: the company is right, the whole estate is a bit big.
Wellard
About 3,075 homes at The Village at Wellard, and they also build elsewhere. Offer a stage, not the entire estate.
Right company, large estate
They keep making new suburbs or industrial land. The project we can measure is several times one microgrid.
Ellenbrook
A proposal, with Heidelberg, for about 4,000 homes on land west of Ellenbrook. That is several contracts.
Ellenbrook
The company that holds the sand lease on that same land. They are in the proposal with Hesperia. They are not a housing brand.
Banksia Grove and Alkimos
Named on Banksia Grove, about 4,000 homes on 338 hectares, and on other northern estates.
Banksia Grove
The company delivering that estate with the state: about 4,000 homes on 338 hectares.
Airport North
About 223 hectares of industrial land. Much larger than 75 hectares, and the same kind of place as Peel.
Across Australia
The awards credit them with more than 70,000 homes across Australia. That is a company total, not one Perth estate.
Worth a second look
The page names them as the developer of a place. It does not say how many homes or how many hectares. Lendlease at Alkimos, Mirvac, Wolfdene, Richard Noble and Gold Estates are in this group. Absence of a number is not the same as being small.
Real, and the wrong size
A tall building can use a lot of power. It is still one building, connected in the ordinary way. A precinct grid is for many separate lots.
Bentley
A student campus of up to 916 beds. One address, not a suburb.
Subiaco
447 apartments in one project. Large, and still one building.
Nedlands, Perth, Kenwick
Three townhouses, 28 homes, and 34 apartments. Too small for this kind of grid.
Mostly apartment builders and small estates. The public page does not say how big the project is.
A company name on a single development application. No suburb was kept, and no size. Any one of them might be a real project. There is not enough on the page to say.
Leave these
They are on the public builder register. They put up houses for other people. They do not usually decide how a new suburb gets its electricity. They are kept in the database so they are not mixed up with the land developers. They are not listed name by name here.
Broome, Dampier and Wickham are not on the South West grid that serves Perth. The names are the Shire of Broome, Hamersley Iron, and Rio Tinto Iron Ore.
