Utilities using drones to monitor power grids and energy systems
By John McMalcolm
Drones are one of the most intriguing technological innovations that have emerged in recent years, and they are taking the world by storm.
In the past, these devices were mostly used for military purposes, but now, they are increasingly being used in domestic applications. One of the sectors that are showing considerable interest in drone technology is the utilities sector.
Many utility companies are beginning to realize the potential of drones as tools for providing a new level of surveillance of their utility systems, and some of them are already testing drone technologies and developing prototype systems.
Here is a look at some of the possible uses of drones in the utility industry:
Locating downed power lines
When power lines go down, they can cause a lot of inconvenience for the residents who are affected, and it can be difficult for utility companies to locate them.
In an effort to make the tasks of locating and repairing fallen power lines more efficient, some utilities are conducting experiments with drones. Equipped with simple optical cameras, these drones are relatively inexpensive to produce, and they can fly for several hours.
They can be launched quickly to locate downed power lines, count downed utility poles and help field workers determine what they need to replace in a particular area. They are especially useful for assessing storm damage in remote areas that are difficult to access due to flooded roads and fallen trees.
However, drones will not completely replace the helicopter fleets of utility companies, because they may not be able to provide proper surveillance in severe weather and heavy fog.
Some utilities are also considering using drone technology to monitor their gas, oil and water pipelines.
Drones can significantly reduce the risk of damage to pipelines by speeding up message and response times. The messages they deliver may come with graphical material to make it easier for the staff to preselect and prioritize them. Additionally, drones can be deployed to monitor the progress of pipeline constructions and reconstructions.
Another benefit of using drones to survey pipelines is that they are more environmentally-friendly and produce less noise than helicopters.
Big data and drones
According to an article titled “Big Data Meets the Little Drone,” the volume of data produced will increase significantly when drones are employed.
Small drones are able to fly at low altitude, and they are the perfect devices for capturing precise images and data. Digital images and videos are not just images or image composites; they actually result from the processing of visual light as a binary numeric representation of images, meaning that light is converted into digital data. The higher the resolution of a camera, the higher the amount of data captured.
Utilities that are planning to use drones should consider implementing a big data solution to manage and analyze the large amounts of data that will be produced during their drone surveillance activities.
Drones hold promise as effective surveillance devices for utility companies.
As drone technology continues to advance, it will not be long before utilities can take to the skies with these little flying robots.

Hydrostor receives $4m funding for A-CAES facility in Canada
Hydrostor has received $4m funding to develop a 300-500MW Advanced Compressed Air Energy Storage (A-CAES) facility in Canada.
The funding will be used to complete essential engineering and planning, and enable Hydrostor to plan construction.
The project will be modeled on Hydrostor’s commercially operating Goderich storage facility, providing up to 12 hours of energy storage.
Hydrostor’s A-CAES system supports Canada’s green economic transition by designing, building, and operating emissions-free energy storage facilities, and employing people, suppliers, and technologies from the oil and gas sector.
The Honorable Seamus O’Regan, Jr. Minister of Natural Resources, said: “Investing in clean technology will lower emissions and increase our competitiveness. This is how we get to net zero by 2050.”
A-CAES has the potential to lower greenhouse gas emissions by enabling the transition to a cleaner and more flexible electricity grid. Specifically, the low-impact and cost-effective technology will reduce the use of fossil fuels and will provide reliable and bankable energy storage solutions for utilities and regulators, while integrating renewable energy for sustainable growth.
Curtis VanWalleghem, Hydrostor’s Chief Executive Officer, said: “We are grateful for the federal government’s support of our long duration energy storage solution that is critical to enabling the clean energy transition. This made-in-Canada solution, with the support of NRCan and Sustainable Development Technology Canada, is ready to be widely deployed within Canada and globally to lower electricity rates and decarbonize the electricity sector."
The Rosamond A-CAES 500MW Project is under advanced development and targeting a 2024 launch. It is designed to turn California’s growing solar and wind resources into on-demand peak capacity while allowing for closure of fossil fuel generating stations.
Hydrostor closed US$37 million (C$49 million) in growth financing in September 2019.
