The Acceptance of Drone Usage For Industrial Purposes

Aerial Powerline and Tower Inspection

As I sit down to write this article and begin framing out my outline, the first thought that comes to mind is “how do I convince an individual drone operator that he or she is qualified to offer powerline inspection services?” and compete at an industry grade level.

When I was getting started, I remember seeing all of the possibilities of using my drone to help the local electric coops inspect the powerline networks in my area. Even in my neighborhood, I would see trees and other foliage growing up around the powerlines, or powerline poles that were damaged in some way whether being damaged by a storm or being hit by a vehicle. In any case, I could see the potential for flying my drone over the powerlines, and providing imagery back to the electric company that would assist them in being proactive with their ongoing maintenance and repair efforts. 

As I began studying the industry, I discovered that public utility companies require a visual inspection every 1 to 2 years and every 3 to 5 years, carry out a highly detailed inspection to assess for pro-active maintenance, upgrades and/or repair. Historically, these inspections are performed by sending out a crew that walk the powerline and climb the poles, or teams with crane-equipped trucks to perform a thorough inspection. This can be a real challenge in metro areas with traffic congestion or in rural areas where terrain may be prohibitive to this these methods, if not impossible. As an alternative, the utlity may procure helicopter services to perform an aerial inspection. This can be exorbitant in cost, not to mention noisy, ecologically unsustainable. On average, a contract for a helicopter powerline inspection can top $4,000 per day, and if a utility were to purchase and operate a helicopter, we are talking up $2 million, with the added costs of operational, maintenance, and repair costs. 

Going back to 2016, drones, for the most part, were still considered to be toys and just beginning to come into age, and companies were not yet looking at drones as a viable solution for aerial powerline & tower inspection. Since then, the commercial drone industry has matured and is now accepted as an industry standard and has burgeoned into one of the top fastest growing industries; on track to top $43.1 billion globally.

So What Does This Mean For Drone Startups?

I’m so glad you asked! What this means for us is that now we no longer have to convince prospective clients of the value of drone inspections! They already get it! And how does this help us as startup and small DSP’s (drone service providers)? Since the market has become more educated on the safety and economic efficiencies of using drones for inspection purposes, we can focus on developing client opportunities and relationships to move ahead with getting those contracts inked. Don’t get me wrong, we still need to call on clients, and present our solutions, but we are perfectly positioned to offer industry grade solutions at prices that make sense to the client.

One thing I should mention here. Small DSP’s do receive criticism for under selling larger and better established drone operators. The way I overcome this criticism among my peers is to explain that because I am a small operator, generally working from a home office, with almost zero costs and overhead, other than our gear, we can still be profitable offering lower pricing. That does not mean we want to diminish our value as a smaller operator by offering dirt cheap prices, but in a highly competitive industry, we have to position ourselves where we can acquire the work and sustain our business.

Getting Your Drone Powerline Inspection Service Started

Performing aerial powerline & tower inspections can actually be a lot of fun. The first thing I love about drones is flying. Many of the inspection services we will perform utilize automated flight plans that are pre-programmed in the controller prior to launching the mission. Conversely, powerline inspection requires skilled manual flight by the pilot.

In the list below, I provide the two primary components to consider when setting up your powerline and tower inspection service.

  1. Equipment – to be competitive, you will need to have the capability to capture high resolution (visual/rgb) and thermal imagery for proper analytics and reporting.
  2. Data Analytics – this is the actual analysis of the visual and thermal imagery in order to provide the reporting to the client.

I do not want to over simplify or make it seem easier than reality to perform this service. But at the same time, it really just boils down to providing the client with the imagery and reporting they need to assess the condition of their power network and assets.

There Are Two Types of Powerline Networks

Before we deep dive into setting up our inspection service, we need to understand there are 2 types of power networks.

Transmission and Distribution refers to the different stages of carrying electricity over poles and wires from the origin of power generation to a home or a business. The primary distinction between the two is the voltage level at which electricity moves in each stage.

  1. Transmission – is like an interstate highway moving bulk electricity from origin generation sites, over long distances to substations closer to areas of demand for electricity. These are the massive towers supporting wires over long distances. These lines, transformers, substations and other equipment have voltages of 100 kV (100,000 volts) and above.
  2. Distribution – refers to the system of powerlines typically carrying the electricity from the substation to our homes and businesses. These lines can be found overhead, along our streets or sometimes in the ground, and, combined with transmission lines make up “the grid”.

The reason that this is important to us, is that there are significant differences in the way we approach these two systems. For the purpose of this article, I am focusing primarily on the distribution network. These are typically owned and operated by the local electric coop making them more accessible to us (as a drone startup) to offer our services. Transmission networks can be owned and operated by national companies and may be more difficult to engage as a small drone operator.

A common thread you will find throughout all of my articles is the importance of knowing where we live (so to speak). This is not to limit our potential, but there is no shame in small beginnings. We learn to walk before we run. Be ambitious, but it can take years to build a good reputation, and only one mistake in a brief moment can destroy a good reputation.

The type of equipment needed to inspect transmission powerlines needs to be resistant to the higher voltage emissions. This is known as EMI or electromagnetic interference. These currents can degrade the performance of susceptible devices including our “prosumer” drones, such as the Inspire, Phantom and Mavic platforms. When we decide to move into working with transmission networks, we will need to look at upgrading to actual industrial grade drones such as the DJI Matrice platform.

drone gear for powerline inspection

What Drone Gear Do I Need?

Define your service offering based on your gear and skillsets you already have.

In order to perform a drone aerial powerline & tower inspection, the first thing to consider is what equipment do you have and what will you need. As with anything, there are multiple ways to approach this, you will just need to determine the niche you are best equipped to carry out.

In my case, I started out with a DJI Phantom 4 and later purchased the DJI Phantom 4 Pro. With this drone, I was fully capable of providing the “Visual” imagery for the inspection, but quickly realized I would need a thermal sensor to provide thermal imagery. Visual and Thermal are the main 2 images that the client will expect as part of the reporting.

DRONExpert Vue Pro R mountThere are thermal camera kits available to modify the Phantom and Mavic “type” drones. Click HERE to check out some of these options for consideration.

Mavic 2 Thermal GimbalThese kits allow you to utilize the Phantom or Mavic drone you already have and will give you the capability to capture both visual and thermal imagery for the inspection report.

Depending on your budget, another option to consider may be to purchase an integrated drone such as the following options:

Parrot Anafi Thermal Drone 4K (click the image for more information)

Autel EVO II Dual Thermal & 8K Camera (click the image for more information)

DJI Mavic 2 Enterprise Dual Thermal Drone (click the image for more information)

There are many different ways you can gear up, and I suggest taking time to shop on eBay or other online resources for used equipment. You can equip yourself with a second-hand Inspire 1 or 2 with an XT2 DJI Inspire 1 with Thermal XT2and you’re off to the races. The added benefit to going this route is that it opens you up to other services you can offer.

Now that you are equipped with gear, the next step is to develop and establish the proper methodology to go out and perform your Drone Aerial Powerline & Tower Inspection operation. In the following section, I provide details to properly plan out your powerline inspection mission.

Fortunately, for all of us, our first mission only happens once! Then our next subsequent missions improve based on the experience we gain, and as we continue, our efficiencies improve until we have refined and established our standard methodologies for each of our services.

One of the most important things will be to create a checklist. This checklist will include everything from the client details and location of the inspection, the equipment and supplies you will need, as well as your pre-flight and flight planning checklist. Personally, I go about every mission as if it is my first; meaning, I do not assume I have every cable, battery or prop, I always refer to my checklist to confirm every single item. As a *side note*, be sure to NOT allow the client or anyone who might accompany you (invited or not) cause you to feel rushed or distracted. This can absolutely cause mistakes to occur that can disrupt the mission, or worse, force a rescheduling of the job. It is very important to be systematic as you arrive to the location, set up your gear and launch your drone.

In the days leading up to the scheduled mission, it is good exercise to do some pre-arrival research of the areas along the powerlines to understand access and potential obstructions or terrain that might cause hinderance to the inspection. Upon arrival, be sure to carry out a thorough onsite reconnaissance of the location. This research can make the difference between a successful mission, or a dismal fail. You can usually find a google map of the site that will help you determine proximity to potential restricted fly zones such as nearby airports or military bases. You can simply refer to an FAA approved app on your m,obile device for LAANC approval. LAANC provides access to controlled airspace near airports through near real-time processing of airspace authorizations in approved altitudes. In any case, just follow your local FAA guidelines to acquire any necessary waiver. I assure you, it’s not difficult, but it is very important. My motto is to always be prepared in advance to avoid any disruption or cancellation of the mission.

I also recommend acquiring flight insurance for the mission. I use Verifly which is on-demand liability insurance coverage for commercial drone flights. You can purchase upfront by the hour, day, or week depending on the mission.

In the next section, I will discuss some high level guidelines for performing the powerline inspection.

Powerline & Tower Inspection | Flight and Data Acquisition

OK! After building out your solution, executing your marketing plan, and you have been awarded the client contract… Now is the most important part of the job!

Flight ops and data acquisition is obviously what the client is paying for, and quite honestly they are not necessarily interested in your cool drone hardware, or your checklists, but they will be eagerly looking forward to the data, and by the way, I am not speaking about handing them a thumbdrive with photos or video. The data that the client will be looking for will be packaged in a professional report that includes the imagery, annotations of  notable issues and other overall statistics. But never fear! just keep reading to find out how I accomplish this report. However, that being said, there are different ways that a client may engage your services. The following are the main two different methods. You will already have negotiated this prior to winning the contract.

I. The client will ask for the raw imagery and perform their own processing of the “data” themselves.

If the client, or electric coop in this case, is insisting that they only need the flight acquisition done, then absolutely, respond with your proposal, win the project and go fly it!

I could go into a lot of depth here, but to keep it simple, you will run into different client scenarios with powerline inspections. 1) the client is the actual owner/operator of the electric coop and powerline network. Or 2) the client is a data analytics and processing company needing drone flight acquisition.

In any case, it’s possible, maybe even likely that they will only want you to perform the flight acquisition. Early on, this sounded perfectly logical and reasonable to me, however, this will not only limit or minimize your income potential but can also devalue your brand, and by going along with this, I realized I was losing repeat business because I was pigeonholed as being JUST the Drone Guy. Always remember to ask yourself, what is the end-game for the client? Flying the drone is only part of your value. The REAL Value is the DATA or the analytics and reporting deliverables. To earn the respect of the client and build a real business partnership, you must be able to provide the full solution. I recognized that I was not a solar engineer or technician so how would I be able to provide reliable analytics reports? Don’t worry, YOU CAN! More on this later in the article.

II. The client will ask for the full inspection, including flight acquisition, data analytics and reporting.

This is EXACTLY what we want! First, let me encourage you, this is nothing to be afraid of. Honestly, in the beginning I was intimidated and fearful of this part of the equation and only offered the flight acquisition. If only I had known then what I quickly  learned, was that I can outsource the data processing online and at a relatively inexpensive cost! There are companies that specialize in the analytics and processing, offering anonymity that allows you to deliver the complete inspection under your own logo and brand! SO NOW, you are not only the drone operator, but you are the solution provider! Again, as I said earlier, it’s all about presenting value to your client. And now, as a benefit to the client, they have your 3rd party report that they can utilize to go out and perform preventative maintenance and/or remediation to the power network. Additionally, by having a 3rd party report, they can provide this to board members, investors or stock-holders to provide assurances that the power network is being properly monitored and maintained.

In the next section, I will provide you with resources who can perform these analytics by using your flight data.

Data Processing, Analytics And Reporting

As I have described so far in this article, we have tremendous resources to provide us with data processing, analytics and reporting. You will want to research the best solution for you based on your personal criteria. A few things to consider are the client requirements, your budget, the turn-around time for the final reporting. Some companies will offer you the option to place your branding on the reports, but this will usually come with a premium subscription. As a tip, I have experienced being able to customize the reporting in order to place my logo and brand the reporting as my own. These are things you will need to think about when determining what solution to go with.

When crafting your proposal, you will need to factor this cost into your price to the client. You will take their cost to you and add your mark-up for managing the process, and you will need to determine the percentage based on your comfort level or the client budget. Also, this is just a side-note, I have found that these companies are very cost-conscious on these inspections. But remember, you are uniquely positioned, as a small business, to keep your costs minimized and be able to offer the client a competitive price while delivering a professional industry standard product at a reasonable profit.

Below, I list my preferred partner for reference.
