A Look at Energy Theft and How Testers Can Help

29 November 2017

Energy theft is not something we often discuss. Testing equipment is usually used to detect faulty or old equipment so it can be fixed and/or upgraded within a company’s closed system. With energy theft, the testers are not only helping to combat this criminal act, but also helping to find and fix safety hazards where people have hacked into the electrical grid illegally, and sometimes dangerously.


Energy theft siteIt is estimated that over $8 billion worth of energy is stolen each year – with the highest losses in India ($16.2 billion), Brazil ($10.5 billion) and Russia ($5.1 billion) according to Emerging Markets Smart Grid: Outlook 2015 study done by the Northeast Group, LLC.  And, according to the U.S. Energy Information Administration, it is estimated that between one-half and two percent of electricity in the United States is lost to theft as well.


Energy theft can cost utilities tens to hundreds of thousands of dollars if they are not paying close attention to their meters.  It is no longer like the old days when service personnel was sent out to check on installations and do meter readings.  Today, nearly all readings are done remotely in the utility company’s office.  Furthermore, stealing energy is easier than ever, with people knowing much more than they once did thanks to DIY projects and widespread knowledge through the internet.  Let’s face it, you can Google or YouTube how to do just about anything these days.  


With that said, how in the world do companies stop this from happening to them?  Clearly, more boots on the ground can help stop this.  But how? If the tampering isn’t something as obvious as someone turning a meter upside down so that it calculates backward, or noticing a magnet that has been attached to the meter that interferes with the inner workings of that meter, slowing down the rotation of the disc that calculates what you are using, how does it get detected?


First and foremost field techs need to be vigilant.  Your most powerful tool is your eye.  Look to see if anything looks out of place, removed or replaced.  Seals of meters should be checked regularly.  Look for things like lights on in a home when power was cut off weeks ago.  Does it appear that power is running on a property that doesn’t have an account with the utility company in the area?  These are red flags and something to look into.

Regardless of how companies detect and deal with energy theft, it DOES need to be dealt with.  It is as serious as any other crime where theft is involved.
