Asset Inspection Services

In today’s world, energy companies are faced with maintaining ageing infrastructures while providing maximum uptime and reliability for end user while keeping costs low. This has spurred the need for Safer and More Efficient asset Inspections compared to traditional methods.

PLP offers an end-to-end solution for collecting data and reporting on the condition of utility assets and vegetation encroachment. Using Unmanned Aerial Systems (UAS) or aircraft as a tool, combined with PLP’s Industry knowledge, advanced data analytics, PLP is positioned to provide actionable data and insights, understanding the asset condition in order to reduce SAIDI/SAIFI and focus spending.


Our comprehensive visual inspection services include high resolution and infrared (IR) image data collection, assessment and classifications of assets by our highly trained and experienced analysts and engineers, secure data management, and delivery of an actionable data set including a final summary report. PLP’s reliability concern classification aligns with the EEA Asset Health Index scaling of H1 to H5. Artificial Intelligence (AI) is being used to aid the analysis of images captured to efficiently process the high volume of images from inspections.

LiDAR data capture of networks is becoming more prevalent globally due to technology improvements of sensors and speed of data capture. Multiple sensors can be added to the aircraft when capturing a network. These include the laser sensor and multiple cameras (Forward/Nadir/Backward) making an ideal tool for the capture of power networks.

LiDAR data enables network owners to create a digital twin of their network. It provides not only inputs into vegetation management, but also into engineering design, line sag and accurate location of assets. PLP have the added offering of the installation of bird diverters onto lines by means of drones.
