  3. 3. Esri UC Wrap-upBy Jessica Wyland, Esri WriterUtility professionals attending the 2012 Esri International UserConference (Esri UC) held July 23–27 in San Diego, California, weretreated to sessions on innovative uses of GIS, operational awareness,alternative energy, and more. They had a custom Plenary Sessionwhere Bill Meehan, Esri’s director of utility solutions, shared a vision:utilities maximize geospatial resources to predict problems, performlocation analytics, manage workflows, and understand customer needs. “GIS helps your utility go from ‘We hope so’ to ‘We know so,’”Meehan told a crowd of nearly 200 at the electric and gas PlenarySession. The audience was then treated to real-world demonstrationsof Esri’s latest technology, including ArcGIS Online, which enablesutilities to share data and collaborate and to provide access to ArcGISfrom any device.The week held other highlights for utility professionals: an Electric andGas User Group (EGUG) meeting, an EGUG Social, and a Smart GridModeling Workshop. The edification and fun continue this fall with the Esri Electric andGas GIS Conference, October 7–10, 2012, in Salt Lake City, Utah. the Winner Is . . .Esri recognized more than 170 organizations during the SpecialAchievement in GIS (SAG) Awards ceremony at the annual Esri UC. TheSAG Awards acknowledge innovative and intelligent applications ofGIS technology. “Each year, the SAG Awards highlight extraordinary achieve-ments and efforts to improve our world,” said Esri president JackDangermond. “At Esri, we are always deeply impressed with the workof our users. This recognition is well deserved for how they’ve appliedgeospatial technology to address the needs of their industries andcommunities. They are defining GIS best practices.” Organizations from around the world honored at the Esri UC spanindustries including agriculture, cartography, climate change, defenseand intelligence, economic development, education, government,health and human services, telecommunications, and utilities.

  4. 4. Shine OnUtility Saves Money by Mapping Street and Security LightsBy Josh Snoddy, GIS Coordinator, Holy Cross EnergyHoly Cross Energy, an electric cooperativein western Colorado, recently updated andcorrected its billing system for the cost ofstreet and security lighting—a move that issaving the utility and some of its customershundreds of dollars per month. Holy CrossEnergy staff digitally mapped security lightsand streetlights within its service area usingGPS, aerial photographs, and a custom webmapping application powered by Esri’sArcGIS technology. A member-owned cooperative foundedin 1939, Holy Cross Energy serves more than55,000 meters in communities such as Vail,Aspen, and Beaver Creek. The security and streetlight project gotunder way in May 2010 after Holy Cross Energystaff determined that the utility’s maps neededto be updated with the exact locations ofstreet and security lights. Staff started with var-ious levels of information in its billing systemand incorrect or missing map information. First, the utility sent crews into the fieldto collect the exact GPS location for eachstreetlight. In the past, the locations of streetand security lights were created withoutGPS points. Some streetlight locations werecreated in previous CAD programs. In othercases, the location of a streetlight was en-tered into the GIS based on proximity to thebilling address on file.

Dakota Electric: One VisionaryRural Electric UtilityBy Len Jewell, Senior Consultant, POWER Engineers (formerly technical systemsmanager, Dakota Electric Association)Like most utilities, Dakota Electric Associationhas made a significant investment in its GISand needed to determine whether the utilitywas getting all it could from the system. Toassist in this determination, utility operatorsformulated the following yes-or-no questions:•• Can the users who are responsible for a particular piece of GIS data maintain it themselves? Can non-GIS users edit the data stored in the GIS?•• Is information exchanged automati- cally between systems? Is information only entered once and shared with the other systems?•• Have the Dakota Electric systems cap- tured and documented the company’s workflows and procedures?

  12. 12. Keeping the Electric Vehicle Alive continued from coverand the best way to prepare for it,” said Brown. Brown, Nelson, and the NES DistributionPlanning Group work to ensure that the elec-tric network has adequate capacity to meetcustomer demand. “If people come home from work aroundfour or five o’clock in the afternoon on a hotday, plug in their electric vehicles, and turn ontheir air conditioners, we have to build up theinfrastructure to serve that load,” Brown said. Since it takes the Leaf eight hours to geta full charge, Brown figured most vehicleowners will plug in at home. NES needed toprofile the people who would likely purchasean electric vehicle and then identify wherethey live. Brown and Nelson chose Esri ArcGIStechnology to create the predicted electricvehicle adoption maps because NES hasworked with Esri software for the past 15 yearsand has mapped all its electric facilities inArcGIS. Naturally, the utility wanted to be ableto relate the study data to the locations of itselectric facilities. The maps were designed and prepared in2010, two years ahead of the Leaf’s deploy-ment, to help the utility prioritize maintenanceprojects, upgrade outdated equipment suchas wires and transformers, and shore up facili-ties that would likely experience heighteneddemand.Pinpointing EV Hot SpotsThe NES team surmised that with a few small  The map (left) shows the state of Tennessee with the NES service area outlined in white anddifferences, EV buyers would closely resemble existing electric vehicle load as green crosses on the predicted heat map.
