Not all utilities are that far along in planning for large EVs.

'This is the kind of of advanced planning that as a utility you're going to have to do.' 'We're looking at trying to identify where are all of the fleets and put this all on a tableau map,' he said during his presentation, 'trying to understand the size of the fleets, what's the makeup of them, what kinds of vehicles, and trying to do some forecasting.'ДЄ fleet of 200 Class 6 and 8 vehicles, for instance, would likely require a second substation to serve their load, Treichler said. To prepare for large EVs, Oncor is already analyzing the potential locations of electric fleets in the future. If Oncor is to electrify all of those vehicles, 'we're going to have to figure out ways of putting substations into very densely populated warehousing districts and bringing transmission into those areas,' he said, 'which is a very expensive process.' 'What do you see when you fly into Dallas? A sea of warehouses as far as you can see,' he said.

For the logistics company, Oncor calculated that charging all of its 325 fleet vehicles would add 40 MW to the customer's power demand - a huge increase over the 0.5 MW load the utility typically sees from a commercial ratepayer.ДЄnd that's just one company of many, Treichler stressed. 'One of the things that brought this whole issue to our attention was about six or eight weeks ago, we got an inquiry from a company that wants to build a logistics center just outside of Dallas.'ДЄt the outset, Oncor expects most large electric vehicles will operate during the day and come back to a central depot to charge at night, creating big pockets of electricity demand that were not there before. 'The things around trucks are starting to happen,' Treichler told the conference audience. Amazon, for instance, bought 100 EV vans from Mercedes for its German operations last year, and this month invested $700 million in the EV startup Rivian.ДЄlready, Treichler said, Oncor is getting inquiries about vehicle charging from its commercial customers. The utility expects large EVs could be cost competitive with traditional gas-fueled options in the early to mid 2020s, Treichler told Utility Dive after the event. Oncor, which serves more than 10 million people in and around Dallas, Texas, is preparing for that shift to begin soon. 'They're all gas today, but once you start converting all of those 20,000 vans per year into electric, how do we as Oncor, a utility, get ahead of that issue?' Imminent shift 'Recently, our friends at Amazon bought 20,000 Daimler Sprinter vans to deliver their packages in one year,' Treichler told an audience at the DistribuTECH convention in New Orleans, Louisiana, this month. Those could necessitate transformative changes to parts of Oncor'sВ distribution grid due to their charging needs. The issue, Treichler said, comes with larger EVs, like Class 6 and Class 8 trucks used for deliveries, and larger electric semi trucks being piloted by Volvo and Tesla.
