In addition to the operational cost savings, the eight best vehicles would reduce CO2 emissions by 38 percent or 270 tons over the remaining life of the vehicles. The largest component of the TCO is the fuel savings. Based on the assessment results, the City and Utilities would reduce fuel consumption by 42 percent or approximately 26,499 gallons if the selected vehicles were converted to plug-in hybrids or all electric. The Elk River Municipal Utilities vehicle is used by the Key Account Manager for day-to-day business meetings in and around town and will be used on longer trips to meet with statewide organizations. The Chevy Bolt has a maximum battery charge of 60 kWh with a maximum range of 240 miles. The miles decrease significantly in cold weather. A recent experience showed the maximum capacity of the batteries at -33 degrees Fahrenheit at 158 miles. When temperatures are subzero for multiple days, the EV should remain plugged in at all times. This hybrid vehicle can travel 22 miles on the battery and then the internal combustion engine will take over to provide the supplemental power with an estimated maximum range of 310 miles utilizing the battery and internal combustion engine. The hybrid models provide for more flexibility with the fuel switching available to extend the overall range. Beneficial Electrification What Elk River Municipal Utilities set out to accomplish in 2016—increase energy sales, improve the utility system load factor (load management), and decrease greenhouse gas emission—is currently driving some significant policy changes in the electric industry today. The popular phrase used today is Beneficial Electrification, also referred to in past scenarios as "load building." According to the Environmental and Energy Study Institute, "Beneficial Electrification refers to the replacement of fossil-fuel powered systems with electrical ones in a way that reduces overall emissions, while providing benefits to the environment and to households." Over the study period, 54,733 kWh were sold to eight customers in their homes. These incremental sales are significant load growth for each participant. The average sales sold to the eight participating customers was 2,280 kWh per month. Of those energy sales, 83 percent were during the off-peak times, which help all customers by improving the system load factor and reducing costs to all customers. In an effort to maximize the greenhouse gas emission reductions from vehicles, Elk River Municipal Utilities automatically includes 100 percent renewable energy for customers participating in the electric vehicle charging program. Applicability (Critical Lessons Learned) • Customers do not like connection fees. Connection fees make topping up for a few kWh while out running errands extremely expensive. 27 66
