The initial rates <br /> were $1/hour for the first 3 hours and $3.5 per hour after that.The dollar per hour charge for a <br /> Level 2 charger with a capacity of 7.2 kW is equal to about $0.14/kWh. The rate for the DC Fast <br /> Charger, which has a capacity of 50 kW, is equal to about$0.02/kWh. <br /> After the first few months, the software was upgraded so the Time-of-Use (TOU) rates could be <br /> displayed for customers to see. At this time, Elk River Municipal Utilities implemented a <br /> connection fee to recover fixed costs (equipment) and the TOU energy rate to cover the <br /> variable cost (kWh costs). Public charging customers were very happy with the flat fees of the <br /> dollar per hour for both the Level 2 and DC Fast Charger. When the connection fees were <br /> implemented along with the TOU energy chargers, the feedback was generally positive for the <br /> initiative to install infrastructure, but the cost was too much for people only needing a few kWh <br /> per charging session. <br /> 14 <br /> 53 <br />
