Our expertise lies in providing industry leading solutions to intricate challenges within the power distribution sector. Our project portfolio showcases our innovative methodologies and successful implementations.
ADMS IMPLEMENTATION
GE PowerOn ADMS Implementation with Five Major New Zealand Distribution Companies
We successfully supported five major New Zealand Distribution Companies in implementing GE PowerOn ADMS. Collaborating with New Zealand’s largest Electricity Distribution Businesses, we acquired a deep understanding of what it takes to successfully deploy such complex systems.
These projects demonstrate our proficiency in merging cutting-edge technology with existing infrastructure, ensuring enhanced operational efficiency and reliability for our clients.
Global Leader in Distribution Power Flow
Distribution Power Flow (DPF) – NZ First
One of the key areas of our ADMS specialty is Distribution Power Flow (DPF), an essential tool for controllers to better assess the network during switching and network events. We have seen firsthand the transformative impact DPF systems can have on our distribution network.
Our Director and Principal Engineer, Hantt Cao successfully delivered the very first DPF implementation project in New Zealand, setting a new benchmark for grid management in the country.
This milestone not only showcases our strong expertise in DPF but has also proven to significantly improve the daily operation of our distribution network. In addition, Hantt Cao has led multiple power flow projects for the State Grid of China, further demonstrating our capability to handle complex and large-scale implementations.
GE PowerOn Advantage & OSI
Outage Management Systems
We are committed to advancing the future of power distribution with industry-leading solutions.
Our team brings a combined 15 years of experience in Outage Management System (OMS) implementation, ensuring that our clients can efficiently manage and mitigate power outages.
Our expertise in OMS spans across the globe, having successfully delivered projects in diverse and challenging environments.
This extensive experience allows us to provide tailored solutions that enhance the reliability and resilience of power networks, ultimately improving the quality of service for end users.
Our commitment to excellence in OMS implementation underscores our mission to empower utilities with the tools and knowledge needed to optimise their operations and deliver exceptional service.
Grid Management Platforms
Advanced Distribution and Transmission Grid Management
Grid Management Systems
We engineer and enhance advanced distribution and transmission control platforms that operate at the core of modern electricity networks. Our expertise spans real-time monitoring, outage orchestration, switching management, network optimisation, and integrated analytics — enabling operators to manage increasingly complex grids with confidence and precision.
By combining deep operational knowledge with automation, scalable architecture, and intelligent data integration, we ensure grid management systems are resilient, adaptable, and prepared for evolving demands such as DER penetration, electrification growth, and dynamic load behaviour.
Outage Management
We engineer and enhance outage and asset management systems that coordinate network events, switching workflows, and asset lifecycle intelligence across complex grid environments. These platforms enable structured outage orchestration, safe switching operations, and integrated visibility of network assets from fault detection through restoration.
By integrating real-time operational data, automation frameworks, and advanced analytics, we help utilities improve restoration times, strengthen operational governance, and optimise asset performance across the full network lifecycle.
Operational Data & SCADA Platforms
We design and optimise high-performance SCADA, telemetry aggregation, and real-time event processing environments that form the digital backbone of modern grid operations. These platforms ingest, validate, and harmonise large volumes of operational data from substations, field devices, DER assets, and external systems — enabling unified situational awareness across the network.
By architecting scalable data pipelines, resilient communication frameworks, and structured event processing logic, we ensure operational data is accurate, timely, and actionable — supporting intelligent decision-making and advanced grid optimisation.
Deployment & Infrastructure Environments
We architect and operate secure, scalable cloud, hybrid, and on-premise infrastructure environments that power mission-critical grid management systems. Our engineering approach ensures high availability, controlled deployment workflows, and resilient system performance across complex operational landscapes.
Through Infrastructure-as-Code, automated provisioning, and structured configuration management, we deliver repeatable, governed environments that reduce risk, accelerate upgrades, and support long-term platform evolution.
