The program is being developed in anticipation of the launch of several production PHEVs over the next two years.

The ChargeWise outlets will charge PHEV batteries between the hours of 11 p.m. and 7 a.m. when demand for electricity is at its lowest and the price for wholesale electricity is also at its lowest. Charging the batteries during these hours also allows Great River Energy to “store” wind energy allowing PHEVs to receive a significant amount of power from renewable sources.

“It’s cleaner, greener and cheaper than gasoline,” said Gary Connett, Great River Energy’s director of member services and demand side management. “As more wind energy is added to the electric grid, plug-in hybrid electric vehicles will get even greener.”

To help get the program started, Great River Energy and its member cooperatives will cover the cost up to $500 of the ChargeWise outlet installation for the first 50 qualified members who are owners of PHEVs.

Great River Energy’s member cooperatives currently offer several programs designed to maximize the use of electricity that is generated overnight, including off-peak “storage” water and space heating.
