Still not quite sure yet what it might cost on a monthly basis to power your electric car when you plug it in at home? Even as California studies through one of its utilities what the cost could be, Michigan’s Public Services Commission (MPSC) approved a plan by one of its state’s utilities, Detroit Edison, to offer specific rates for electric vehicles for residential customers.
Detroit Edison’s plan, according to the MPSC, is an experimental electric tariff that will at most impact 2,500 of the utility’s customers who are optionally seeking separately-metered service for the sole purpose of charging licensed electric vehicles. This test group will have one of two rate options to choose from: one that provides a lower rate for charging during off-peak hours (hours other than between 9 a.m. and 11 p.m. Monday through Friday) and another that provides for a monthly flat fee of $40 per vehicle.
Most, if not all, of those who take part in this experiment receive a separate meter that is capable of recording the energy used to charge the electric vehicles and the time of day that the charging occurs. The utility will fund up to $2,500 for the separately metered circuit including the approved charging station. No mention was made of how long this test rate plan would go on for.
“As manufacturers begin to sell plug-in electric vehicles, it is important that Michigan’s electric utilities be ready as well,” said MPSC Chairman Orjiakor Isiogu, in a statement. “The program approved today will help Detroit Edison evaluate the effect of electric vehicles on its electric system, offers off-peak rates that customers can use to charge vehicles, and offers the infrastructure required to charge these vehicles.”
