Ciraterra — Kemerton SIA Circular Materials Plant & Catalpa Dr Precinct

Owner / SPV Proof	Ciraterra Pty Ltd (co-founded by Matt Barone, Ian Meares & Mark Taylor; Curtin University R&D partner) via stealth SPV CIRATERRA PROPERTY (KEMERTON) PTY LTD (ACN 691 035 748 / ABN 51 691 035 748), incorporated 16 Sep 2025 with GST activated 26 Sep 2025. ASIC + ABR VERIFIED Website (`ciraterra.com.au`) still reads 'Our Projects: Coming Soon'. Adjacent 100 Catalpa Dr Kemerton release held by CATALPA BUSINESS PARK DEVELOPMENTS PTY LTD (ACN 689 354 316, GST Active 23 Jun 2026).
Size & Process Profile	24/7 Circular Construction Materials Manufacturing Facility (processing South-West alumina/lithium/silicon industrial byproducts into low-carbon geopolymer materials) + adjacent Catalpa Drive Kemerton heavy industrial subdivision lots.
Est. Electrical Load	4.00 MW core plant continuous/high-load-factor demand (22.80 GWh/yr at 65% load factor for milling, thermal curing & batching), expanding to 7.50 MW (~34.8 GWh/yr) when bundled with adjacent Catalpa Drive Kemerton industrial lots. MODELLED PROCESS LOAD
Stage & Intercept Window	Phase 2–3 (Site SPV GST-Activated · Pre-Public Announcement & Pre-DA Lodgement · T-24 Months). Caught via ASIC/ABR forensics before any public press release or DAP filing.
Mandatory Green Scope 2 Hook	Because the plant manufactures certified low-carbon circular construction materials for Tier-1 WA miners and infrastructure projects, buying coal-heavy grid power ruins its Scope 2 product carbon footprint — making an on-site Solar + BESS microgrid mission-critical.

THE GRID PROBLEM (WHY CONVENTIONAL WESTERN POWER SUPPLY FAILS HERE)

Kemerton SIA HV Capacity Squeeze: Fed by Marriott Road (MRR) / Kemerton / Picton substations in the South-West SWIS, where heavy industrial loads (Albemarle Kemerton Lithium & Simcoa Silicon) have locked up available feeder headroom and created multi-year Western Power HV connection queues.
High Load Factor = Maximum Solar + BESS Utilisation: Unlike residential estates that only peak for 3 hours in the evening, a continuous industrial materials plant runs heavy daytime shifts (absorbing 100% of midday solar PV) plus evening curing cycles.
Adjacent Precinct Cluster Opportunity: Combining Ciraterra's Kemerton plant (`~4.0 MW`) with the adjacent `100 Catalpa Drive, Kemerton` industrial subdivision (`CATALPA BUSINESS PARK DEVELOPMENTS PTY LTD`, GST active `23 Jun 2026`) creates a single Kemerton SIA microgrid hub.

WHY A PRIVATE MICROGRID WINS HERE

Executive Team Speaks Infrastructure & BOO Fluently: Co-founder Ian Meares is a KPMG Engineering Partner and former National MD of Brookfield Multiplex Engineering & Infrastructure who has led alumina decarbonisation and wind/solar/BESS projects — he immediately understands a 25-year off-balance-sheet BOO PPA/microgrid.
Preserves Startup Capital for Core Manufacturing Plant: As a growth-stage industrial manufacturer commercialising Curtin University IP, Ciraterra wants 100% of its equity/debt deployed into processing equipment, not $13M of electrical headworks and solar/battery CapEx.
Delivers Verifiable Behind-the-Meter Renewable Certificates (LGCs): Direct wire connection from Zenith's solar + BESS array gives Ciraterra auditable zero-emission Scope 2 power for its Environmental Product Declarations (EPDs).

CLOSEST ZENITH PRECEDENT

Peel Business Park (EDL7/ERL28) + Zenith Remote/Hybrid C&I BOO Model: Combines Zenith's traditional single-customer industrial BOO expertise with an expandable Kemerton SIA precinct licence (similar to Peel EDL7 and Busselton EDL10).

LICENCE & REGULATORY ROUTE

Single-site behind-the-meter BOO PPA / embedded network or EDL10/ERL33 non-contiguous licence amendment covering the wider Catalpa Drive Kemerton precinct.

Key Risk Plant engineering and environmental approvals are still in pre-DA design; Zenith must engage Ian Meares & Matt Barone now so the microgrid is baked into their EPA/DWER and Western Power applications from Day 1.

Next Step Call Ian Meares ((08) 9263 7371) or Matt Barone ((08) 6182 4522) to offer a zero-CapEx BOO renewable microgrid that locks in green Scope 2 certification and bypasses Kemerton HV delays.

1. BOTTOM-UP ELECTRICAL LOAD & FEEDER DEFICIT DERIVATION

Step 1 — Continuous Circular Materials Process Demand (High Load Factor C&I)

4.00 MW peak process demand × 5,700 equivalent full-load hrs/yr (65% LF) = 22.80 GWh/yr (11.40 × the 2.0 GWh Slide 4 unit)

Industrial grinding, geopolymer mixing, and thermal curing run high daytime/evening duty cycles (plus +12.0 GWh/yr upside on adjacent Catalpa Dr lots).

Step 2 — Why High Load Factor Supercharges Slide 4 Network & IRCR Savings

Standard Bundled Tariff @ 22.80 GWh = $6,115,512/yr ($1,830,908 WP Network + $1,020,004 IRCR Peak Capacity)

By shaving peak demand behind a 2.50 MW boundary connection and supplying 11.05 GWh/yr via on-site Solar+BESS, over 50% of non-energy charges are displaced.

Step 3 — Optimal Solar PV + 3.4-Hour BESS Dispatch Physics

5.50 MWp Ground/Roof Solar PV (~9.08 GWh/yr) + 3.50 MW / 12.00 MWh BESS = 11.05 GWh/yr Behind-the-Meter Dispatch

Daytime milling directly consumes ~5.2 GWh of live solar; the 12 MWh BESS stores ~3.9 GWh of excess solar + off-peak power to flatten the 16:00–21:00 peak.

Step 4 — Expansion to Full Catalpa Drive Kemerton Hub (7.50 MW / 34.80 GWh/yr)

Adding the adjacent 100 Catalpa Dr industrial subdivision (+3.50 MW / +12.00 GWh/yr) lifts BOO EBITDA from $2.28M/yr to ~$3.45M/yr

Gives Zenith a second South-West industrial microgrid hub halfway between Peel Business Park (EDL7) and Busselton (EDL10).
