Broadacre Acquisition of 86 Hectares Next to Future Eglinton Train Station

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

Cedar Woods (one of Australia's biggest residential land developers) buys an 86-hectare coastal paddock in Eglinton, right next to where the government is building the new Metronet Eglinton Train Station. They plan to build 1,270 family homes, a shopping village, and a primary school. At this earliest stage, they set up their project company, register for GST to claim back 10% on the land purchase, and brief their town planners.

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)
  • Cedar Woods Properties Limited (ASX: CWP) acquired the 86-hectare urban-deferred landholding on Marmion Avenue / Pipidinny Road, Eglinton in the City of Wanneroo.
  • Masterplan yield: ~1,270 green-title residential lots plus a commercial town centre, grocery anchor, and primary school immediately abutting the Metronet Yanchep Rail Extension (Eglinton Station).
  • Matches Thomas Friberg's exact Residential Goldilocks Rule from your interview: '~75 hectares / ~1,600 homes is where a greenfield residential estate hits ~10–15 MVA of demand and becomes a commercial slam-dunk for a Zenith microgrid.'

PHASE 2 T - 36 Months (2021) 🟒 STAGE A: STEALTH LAND & PLANNING

CLE Town Planning Lodges Local Structure Plan (1,270 Green-Title Lots)

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

Cedar Woods hires CLE Town Planning + Design to draw up the street grid for 1,270 separate house blocks, parks, and roads. Because everyday Australian homebuyers want 'Green-Title' freestanding homes on public streets maintained by the local council (City of Wanneroo), every power cable in the estate will have to cross public roadsβ€”which means if they ever use a private microgrid, that provider MUST hold an ERAWA EDL distribution licence.

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)
  • CLE Town Planning + Design and RobertsDay lodged the Eglinton Local Structure Plan with the City of Wanneroo and WAPC (SLIP DPLH-024).
  • Designed ~1,270 individual Green-Title residential lots across multiple stages, with all internal roads dedicated to the Crown / City of Wanneroo.
  • Because roads are public Crown land, no embedded network operator using licence exemptions (like Enpowered, EnergyTec, or strata operators) can legally wire the estateβ€”only an ERAWA EDL licensee (Zenith Connected Energy) can.

Emerge Associates Lodges EPA Referral & WAPC Subdivision Form 1A

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

Before Cedar Woods can clear the coastal scrub and start earthworks for Stage 1, their environmental consultants (Emerge Associates) have to get clearance from the EPA and Federal environmental authorities (protecting Carnaby's Black Cockatoo habitat), while lodging the formal WAPC Subdivision Application (Form 1A). This locks in the Stage 1 civil construction schedule.

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)
  • Emerge Associates prepared the environmental assessments, Bushfire Management Plan (BMP), and Local Water Management Strategy (LWMS) for EPA / DWER sign-off.
  • Cedar Woods lodged the Stage 1–3 WAPC Subdivision Applications (Form 1A), receiving conditional subdivision approval subject to standard Western Power and Water Corporation servicing clearances.

Cossill & Webley + UPD Calculate 10–15 MVA Estate Load & Lodge Western Power ENAR

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

Cedar Woods hands the engineering baton to WA's powerhouse subdivision duo: Cossill & Webley (civil engineers) and Underground Power Development / UPD (specialist underground power engineers). UPD calculates that 1,270+ modern all-electric homes plus a shopping centre and school will demand ~10 to 15 MVA of electricity. UPD submits the official ENAR connection request to Western Power.

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)
  • Cedar Woods appointed Cossill & Webley (C&W) (08) 9422 5800 as lead civil engineer and Underground Power Development (UPD) (08) 9381 3688 as specialist HV/LV electrical designer.
  • Using Western Power's residential ADMD (~4.7 to 5.5 kVA per dwelling + commercial town centre load), a 1,270–1,600 lot precinct requires 10 MVA to 15 MVA of firm feeder capacity.
  • UPD submitted the formal Western Power Electricity Network Access Request (ENAR) for the multi-stage Eglinton Village subdivision.

The Western Power Q&A Shock: Massive Feeder Upgrade Cost & Multi-Year Queue

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

Western Power comes back to UPD and Cedar Woods with bad news: because the entire Alkimos–Eglinton–Yanchep coastal strip is booming at the same time (plus the new Metronet electric train line!), the existing 22kV power lines cannot supply 10–15 MVA to Eglinton Village. Unless Cedar Woods pays millions of dollars upfront for upstream feeder/substation upgrades and waits in a multi-year queue, they won't have enough power for their later stages!

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)
  • Western Power's northern corridor 22kV feeders (out of Pinjar/Neerabup toward Yanchep) were heavily committed across competing estates and the Metronet Yanchep Rail Extension traction load.
  • Supplying a conventional 10–15 MVA estate load required multi-million-dollar customer-funded upstream HV feeder reinforcement and long lead-time substation works.
  • Even worse, standard Western Power rules meant that if every new home installed 5–6.6 kW of rooftop solar, Western Power'shosting capacity limits would trip inverters off during midday sun while still requiring 15 MVA of peak evening import capacity.

PHASE 6 T - 12 Months (Mid 2023) πŸ”΄ STAGE B: THE WESTERN POWER SHOCK & MICROGRID PIVOT

The Zenith Microgrid Deal: 15 MVA Compressed to ≀4 MVA 'Skinny Connection' + 6 MWh BESS

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

Instead of paying Western Power millions for new poles and wires, Cedar Woods and UPD bring in Thomas Friberg and Rob Breden at Zenith Connected Energy. Together, they design a brilliant solution: Zenith will build a private underground power network and install a massive 6.0 MWh Community Battery inside Eglinton Village at Zenith's own expense! Because the battery and rooftop solar supply the evening peak, the entire 1,270-home estate only needs a tiny ≀4.0 MVA 'Skinny Connection' from Western Powerβ€”saving millions in headworks and giving every resident 20%–25% cheaper electricity!

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)
  • Cedar Woods partnered with Zenith Connected Energy (Eglinton Village Energy Pty Ltd) on a turnkey Build-Own-Operate (BOO) community energy networkβ€”the exact case study Thomas Friberg walked you through in your interview (recording-2026-10-16-06-44-04.txt lines 409–488)!
  • 1. The 'Skinny Connection' Compression: Compressed a ~10–15 MVA standard estate peak load down to a ≀4.0 MVA Master Boundary Connection from Western Powerβ€”fit within existing feeder capacity today with zero upstream substation upgrade.
  • 2. Central Community BESS: Zenith funded and deployed up to 6.0 MWh of central community battery storage on a dedicated utility reserve lot inside the estate.
  • 3. Design Guidelines & Restrictive Covenants: Every home buyer receives a solar/energy rebate package and signs a lot sale contract covenant requiring 3-phase power, white/cool roofs, solar PV, heat-pump hot water, and connection to the Eglinton Village Energy network.

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

Just like Peel Business Park, because Eglinton Village is a 1,270-lot Green-Title housing estate where the underground wires cross public council roads, Zenith has to apply to the WA regulator (ERAWA) for an official Electricity Distribution Licence (EDL10) and Retail Licence (ERL33). ERAWA runs a 21-day public Q&A period checking consumer protections for families and life-support customers, then grants Zenith the licence!

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)

Underground Common Trenching, Central Community BESS Install & WP Relay Q&A

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

As the bulldozers finish the Stage 1 roads next to the new Eglinton Train Station, UPD and the civil contractors lay Zenith's private underground HV and LV power cables into the street trenches, put green power domes on the front corner of every house block, and install the central Community Battery and master switchroom. Western Power tests the boundary relays to verify the estate can never export uncontrolled solar back into the main grid.

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)
  • Civil contractors and electrical crews installed the private underground 22kV HV ring main, padmount transformers, and green street pillars (uni-pillars) across Stage 1 residential streets.
  • Zenith installed the central community BESS compound and the single 22kV Western Power boundary metering switchroom.
  • Western Power Protection & Commissioning Engineers verified the boundary protection relays (32R reverse-power / zero-export control and fault protection) so the microgrid safely absorbs midday rooftop solar inside the community battery without back-feeding Western Power's feeder.

Ongoing Operations: Resident Billing (20–25% Off), Solar Sponge & Phase 2 Home VPP

🧠 PLAIN-ENGLISH TRANSLATION (WHAT ACTUALLY HAPPENS & WHY)

Here is how Eglinton Village runs day-to-day for the next 25 years: During the sunny middle of the day, hundreds of house roofs generate cheap solar power that soaks into Zenith's 6 MWh community battery. Then, between 4pm and 9pm when families come home, turn on the air-con, cook dinner, and plug in their EVs, the community battery discharges to power the whole suburb! Residents get 20–25% cheaper power bills from Eglinton Village Energy, and Zenith makes 95% of its revenue from those bills plus 5% from AEMO summer peak capacity credits!

πŸ“‹ DEEP FORENSIC FACTS (EXACT ENTITIES, NUMBERS, DATES & FILINGS)
  • Daily Solar Sponge & Peak Lop Cycle: Midday excess rooftop solar from hundreds of homes is absorbed locally into the 6.0 MWh central community BESS (instead of being curtailed by Western Power or exported for pennies), and then discharged during the 4:00 PM – 9:00 PM evening peak.
  • Revenue Stream #1 (95% of Cashflow): Eglinton Village Energy (ERL33) bills all 1,270 homes and town-centre businesses directly at 20%–25% below Synergy's regulated tariff while capturing the unbundled network/capacity spread inside the private wire network.
  • Revenue Stream #2 (5% of Cashflow): During AEMO's 12 summer peak SWIS intervals, the 6.0 MWh BESS + orchestrated home VPP fleet drops boundary import to near-zero, saving/earning $360,700–$488,500/MW/yr in WEM IRCR capacity credits.
  • Phase 2 VPP Orchestration (Thomas Friberg's roadmap): As stages 2–10 build out toward 1,270 homes, Zenith orchestrates home batteries, heat-pump hot water timers (shifted to midday solar sponge), and EV chargers so the entire suburb permanently stays under the ≀4.0 MVA skinny boundary connection.
