As part of several technology demonstration projects under study, Madison Gas and Electric (MGE) has purchased six Coulomb Technologies electric vehicle charging stations from Carbon Day Automotive, Chicago, Ill. Electric cars and trucks charged at the stations will have their emissions offset through renewable energy. The project is the first of its kind in the United States.
MGE plans to install the first charging unit this summer and have the network up and operating by early next year.
Last year, MGE purchased one of the state’s first plug-in hybrid cars. This summer, the company will install vehicle-to-grid technology in a new Ford Escape plug-in hybrid, making it Smart Grid ready. This technology allows the vehicle to recharge at low power demand times and can also be discharged to supply the grid with power during peak power demand hours.
This demonstration project will show us how use of plug-in vehicles could eventually affect operations of the electric grid and power supply planning.—Lynn Hobbie, MGE senior vice president
MGE generates and distributes electricity to 137,000 customers in Dane County, Wis., and purchases and distributes natural gas to 141,000 customers in seven south-central and western Wisconsin counties. MGE’s parent company is MGE Energy.
