  • 1. COPPER THEFT A ccording to Don Horne of Electricity Today, copper theft increased 1,150 percent from 2005 to 2006. Unfortunately, things only got worse from there. In 2007, the U.S. Department of Energy called copper theft a $1 billion problem that was growing larger. From January 2006 to March 2007, electric utility companies in 42 states reported 270 copper thefts (many more remained unreported), causing millions in maintenance repairs within the United States. Duke Energy Battles Copper Theft In 2006, Jim Mehring, Duke Energy Kentucky’s general manager of substation engineering, said, “We are seeing a marked increase in the number of break-ins at our substations. In addition to financial impacts, this has created safety and reliability concerns for Duke Energy.” In Greenville, S.C., in July 2006 a man trying to steal copper from a Duke substation was electrocuted with tools and wire still lying near the body.52 UA April 2008 www.utility-automation.com

Duke has invested heavily to findsolutions to deter copper theft, includingprojects in closed-circuit television(CCTV), access control and guardservices. While various approaches helped,they were too cumbersome and expensiveto deploy beyond a few critical locations.In addition, traditional surveillance usingCCTV and DVRs were not as effective asexpected. Clayton Kemp of USA SecurityGroup explains: “CCTV enabled Duketo watch re-runs of the crimes committedthe previous day. We watched hours ofvideos of intruders and never had whatwe needed to identify and prosecuteperpetrators.” Installing CCTV cameras meansrunning wire—lots of it—for mostinstallations, pushing installation costshigher than the equipment itself. In aneffort to reduce installation costs andsimplify deployment, Duke consideredwireless solutions, but they wouldn’t workin the noisy substation environment.Duke Finds a Solution Duke had been working with ClaytonKemp and USA Security Group basedin Charlotte, N.C., to help design anaffordable solution. USA Security hasprotected commercial and residentialconstruction sites for more than sevenyears. Protecting construction sites involvessecuring remote locations, outdoorinfrastructure and porous perimeterswhile still allowing multiple contractorsthe access they need—situations similarto Duke’s substation environment.

According to Kemp, the solution worked because of superior wireless technology: 915 MHz and true spread spectrum, which is used in the U.S. military to deter jamming and give maximum range in hostile environments. Duke ran into a problem, however, because its security problems were primarily outdoors and the Videofied camera was not weatherproof. Kemp describes how his company customized the cameras in an attempt to solve that problem: “We added silicone seals and a plastic hood and began experimenting to better understand the solution.
