Consumer interest in electric vehicles is on the rise and all electric vehicles (EV) and plug-in electric vehicles (PEV) are becoming the transportation of choice. Electric utilities hope to support these emerging loads by encouraging charging these vehicles at off-peak times when energy costs are low and generation and power delivery assets are underutilized. PEV manufacturers are interested in working with utilities to develop customer rates/programs that provide customers with greater incentives to purchase an EV or PEV.
Within a utility service territory the customer can plug in a PEV to receive a charge of electrical energy at his premises or plug in at another premises location. The utility may offer the customer a PEV tariff that provides a lower rate for off-peak charging and a higher rate for on-peak charging. Each time a PEV is charged, customers enrolled in a PEV program, exchange account and energy information with the utility. Energy supplied to the PEV is then reported to the utility for billing and presentation to the customer.
