Engineering Tomorrow’s Power Systems
“From megawatt to multi-hundred-megawatt — engineered for precision, compliance, and sustainability”
Ecologiq provides comprehensive engineering and delivery services for utility-scale renewable energy projects across Australia and emerging global markets. Our expertise spans large-scale solar PV, hybrid battery energy storage, and integrated renewable precincts. We combine advanced modelling, grid-compliant design, and construction supervision to deliver assets that are reliable, bankable, and performance-optimised.
Our Expertise
01/Utility-Scale Solar PV Systems
Plant Layout & Yield Optimisation: Advanced solar farm design using PVSyst, Helioscope, and Aurora Solar for accurate irradiance, shading, and energy yield modelling.
Module & Tracker Engineering: Structural and mechanical design for fixed-tilt, single-axis, and bifacial systems in accordance with AS/NZS 1170 and IEC 62817.
Electrical Network Design: High- and low-voltage collector system design, cable sizing, earthing, and reactive-power management per AS/NZS 3000 and AEMO guidelines.
Performance Verification: PR analysis, degradation modelling, and predictive maintenance planning via digital twins and SCADA data analytics.
02/Grid Connection & Compliance
Power System Studies: Load-flow, short-circuit, harmonic, and stability analysis using DIgSILENT PowerFactory and PSSE to satisfy DNSP and AEMO requirements.
Grid-Code Compliance: Implementation of AS/NZS 4777, IEC 61850, and IEEE 1547 standards for inverter, protection, and communication systems.
Connection Applications & Modelling: Preparation of R1–R2 models, POC drawings, and compliance documentation for registration under AEMO and DNSP frameworks.
Protection & Control Systems: Development of protection schemes, relay settings, and coordinated grading studies for safe network integration.
03/Battery Energy Storage Integration
BESS Architecture & Sizing: Energy storage design for grid support, frequency control, and peak-shaving applications from 1 MW to 500 MW scale.
Hybrid Plant Design: Integration of solar + battery + diesel/microgrid systems with advanced EMS and SCADA controls.
Thermal & Fire Safety Engineering: Compliance with AS/NZS 5139, IEC 62933, NFPA 855, and UL 9540 for battery installations.
Performance Modelling: Round-trip efficiency, degradation, and dispatch strategy simulations to ensure ROI and grid stability.
04/Owner’s Engineer & Construction Supervision
Design Review & Certification: Independent verification of EPC designs, RPEQ/CPEng certification, and constructability reviews.
Procurement & Technical Evaluation: Vendor pre-qualification, FAT/SAT inspection, and equipment compliance assessment.
Construction Monitoring: Schedule control, quality assurance, safety audits, and progress validation throughout site delivery.
Commissioning & Acceptance Testing: Validation of performance guarantees, grid compliance testing, and handover documentation.
05/Operational Performance & Asset Optimisation
Digital Twin & Data Analytics: Real-time monitoring integration with SCADA and EMS for continuous performance improvement.
Predictive Maintenance Programs: AI-based fault detection and performance drift analysis to reduce downtime.
Lifecycle Costing & Asset Management: Evaluation of O&M costs, degradation forecasting, and component replacement planning.
Sustainability Reporting: Carbon offset tracking and ESG performance measurement aligned with ISO 14064 and GHG Protocol.
