Case Studies
As a vital component of the energy sector, electricity transmission networks require precise construction, safe maintenance, and efficient management—key challenges that demand innovative solutions.
GreenValley International (GVI) offers a comprehensive range of hardware and software products that are revolutionizing power line inspection and management across Australia’s vast and varied landscapes. Our advanced equipment rapidly and accurately captures 3D data of power lines and their surrounding environments, even in challenging terrains. This capability delivers invaluable, reliable data to support the entire lifecycle of transmission networks.
1. Challenges and Solutions
Traditional power line inspection methods are often time-consuming, costly, and pose significant safety risks. To address these issues, GVI has introduced advanced LiDAR scanning technology to Australia, offering innovative solutions for the transmission and utility power line industries.
This solution features GVI’s LiMobile and LiBackpack hardware products, paired with the LiPowerline software.
To date, these products have been successfully applied in over 20 projects across Victoria and New South Wales, delivering efficient and reliable results for the energy sector.

3. Achievements and Advantages
3.1 High-Precision Data Processing Capabilities
GVI's LiDAR equipment precisely captures 3D data of power lines and their surrounding environments, including terrain variations, building outlines, and vegetation distribution. This results in highly accurate power line point cloud data, forming a robust foundation for power line design, management, and analysis.
Compared to traditional manual measurement and inspection methods, this advanced technology greatly improves inspection accuracy, while reducing design flaws and safety risks caused by data inaccuracies.

3.2 Efficient Data Collection
GVI’s LiMobile M1 and LiBackpack DGC50 enable flexible operations, allowing large areas to be scanned efficiently in a short time. These tools leverage point cloud-based power line detection to help grid operators map wire profiles—a critical feature in high-traffic areas or regions with significant mechanical activity. Such inspections also allow grid operators to proactively address potential issues before they impact the network.
With this technology, just one or two technicians can inspect a single power line span in as little as 10 minutes. For example, during a power line encroachment assessment project in Flemington, Victoria, the vehicle-mounted LiMobile scanner completed scanning approximately 7.5 km of power lines within an hour, collecting a wealth of high-quality data. This rapid data collection significantly accelerates project timelines and ensures swift progress, providing a strong foundation for efficient project execution.

3.3 Security and Privacy Protection
During power line inspections, certain areas may include sensitive locations such as residential neighborhoods and substations. The remote operation capability of GVI’s LiDAR technology minimizes the need for field personnel to enter hazardous zones, significantly reducing safety risks.
Unlike airborne LiDAR scanning that requires drones to fly over sensitive areas, GVI's terrestrial LiDAR equipment eliminates the need for aerial operations, thus preventing potential damage from drone crashes and protecting privacy by avoiding drone flights over private property. This approach not only ensures operational safety but also helps maintain positive community relations by addressing privacy concerns.

3.4 Risk Assessment and Simulation
Faster data collection and processing reduce operating costs. GVI’s LiPowerline software enables early risk assessment and simulation of power line networks, helping to avoid costly emergencies.
LiPowerline is tailored for transmission, transformation, and distribution scenarios. It analyzes point cloud data to quickly identify hazards and offers features such as early warning analysis, line completion acceptance, multi-period data analysis, and inspection route planning, ensuring safe power operations.
This allows staff to focus on high-risk areas, eliminating the need for large-scale inspections.
