⚡ Grid Flow Correlation & Scenarios

Correlate market dispatch with Western Power transmission corridor thermal loading and reverse power flow.

ℹ️ Substation SCADA & Network Flow

Does Western Power publish live substation data? No. Real-time substation SCADA is protected under the Security of Critical Infrastructure Act (SOCI Act) and WEM confidentiality rules. Instead, GreenSpark correlates live AEMO market generation & system demand with Western Power NCMT physical line ratings and substation catchments via load flow modeling.

Privately Run Grid-Connected Microgrids Peel / Zenith Archetype

⚡ Commercial Model: Privately operated embedded networks behind a single Western Power gate meter (Master NMI). By pairing on-site commercial solar PV, utility BESS, and private distribution, developers deliver 20–35% tariff discounts to industrial tenants while bypassing multi-year substation upgrade bottlenecks.

Filter Opportunities by Siting Driver

#1 Siting Opportunity

Neerabup Meridian Park

City of Wanneroo • Northern Tech Corridor

94 / 100

Headroom 260 MVA

Target Solar 12.0 MW

Target BESS 20 MW / 40 MWh

Thesis: 400+ ha advanced manufacturing and robotics precinct. Abundant buffer land for ground/rooftop solar. A private microgrid provides green power guarantees for corporate tenants and shields them from transmission connection queues.

Substation: Neerabup Terminal (330/132kV) • Model: 25-yr Private Embedded Concession

#2 Siting Opportunity

Hazelmere Logistics & Cold Hub

City of Swan • Bushmead Road Precinct

97 / 100

Headroom 6 MVA (Constrained)

Target Solar 8.0 MW

Target BESS 15 MW / 30 MWh

Thesis: Severe grid constraint (only 6 MVA firm headroom remaining vs proposed 192 MW CDC data centre and cold storage builds). An embedded network aggregating flat warehouse roofs with BESS unlocks immediate capacity without triggering Western Power's 4-year upgrade line build.

Substation: Hazelmere Substation (132/22kV) • Model: Multi-Tenant Logistics Embedded Network

#3 Siting Opportunity

Latitude 32 / Hope Valley

City of Kwinana / Cockburn • Western Trade Coast

91 / 100

Headroom 160 MVA

Target Solar 10.0 MW

Target BESS 15 MW / 30 MWh

Thesis: 1,400 ha major freight and heavy commercial corridor servicing Kwinana SIA and future Westport port. Siting a private microgrid enables concurrent megawatt-level charging for 60+ heavy electric transport trucks without overloading local distribution feeders.

Substation: Kwinana Terminal & Mason Rd • Model: Fleet EV Charging & Commercial Microgrid

#4 Siting Opportunity

Canning Vale Food & Wholesale Hub

City of Canning • Market City & Bannister Rd

89 / 100

Headroom 9 MVA (Constrained)

Target Solar 7.0 MW

Target BESS 12 MW / 24 MWh

Thesis: 100+ wholesale tenants and PTA electric bus depot (10 MW load). Massive flat rooftops on cold stores and wholesale pavilions. Daytime refrigeration compressor loads closely mirror midday solar profile, while BESS shaves the 17:00–21:00 evening peak.

Substation: Canning Vale Substation (132/22kV) • Model: Agri-Food Precinct Private Embedded Network

#5 Siting Opportunity

Kemerton Strategic Industrial Area

Shire of Harvey • South West Cleantech

88 / 100

Headroom 180 MVA

Target Solar 15.0 MW

Target BESS 25 MW / 50 MWh

Thesis: Downstream lithium chemicals hub (Albemarle lithium hydroxide plant). Ancillary Tier-2 engineering, reagent suppliers, and industrial fabricators can cluster into a dedicated industrial microgrid with firm low-carbon Scope 2 power guarantees.

Substation: Kemerton Terminal (330/132kV) • Model: Heavy Industrial Cleantech Microgrid

#6 Siting Opportunity

Avon Industrial Park (Northam)

Shire of Northam • Eastern Intermodal Hub

86 / 100

Headroom 8 MVA (Radial Feeder)

Target Solar 5.0 MW

Target BESS 8 MW / 16 MWh

Thesis: 200 ha intermodal rail, grain processing, and livestock logistics hub on a long rural 66kV radial feeder prone to bushfire line trips and summer heat de-ratings. Private microgrid guarantees continuous 24/7 power and islanding protection for regional export operations.

Substation: Northam Substation (66/22kV) • Model: Regional Intermodal Island-Capable Microgrid
