Environment and the Grid

grid

Mississippi Power continues lowering its emissions by installing environmental controls on its existing coal units and adding new, cleaner sources of generation to its already diverse supply of generation. We continue to invest billions of dollars to produce cleaner electricity. Plug-in electric vehicles can potentially get cleaner over time as the generation of electricity gets cleaner, while gasoline or diesel engines deteriorate over time leading to higher emissions with the age of the vehicle.

Carbon

Gasoline-fueled vehicles have more carbon emissions per mile than electric-powered vehicles.

Battery recycling

The lithium-ion batteries used in PEV's contain non-toxic materials and are recyclable. The automotive and battery industries are working to develop a sustainable recycling model for these batteries.

Also, companies are looking to find 'second life' uses for the batteries. Once the lithium-ion batteries have completed their useful life in automobiles, they still maintain capacity to perform less stressful duties. Companies are working on business plans to create second life uses for these batteries, which include storing excess renewable energy as well as providing community back-up power when necessary.

Solar vehicle charging

Recently, the idea of driving a PEV using renewable energy has become more prominent. As energy sources of wind and solar become more cost-effective, PEV drivers have the opportunity to utilize these resources to fuel their vehicles. Southern Company is evaluating renewable energy generation in conjunction with stationary energy storage. This combination will allow a PEV owner to charge their car on renewable energy conveniently. The results will allow us to educate PEV owners on the benefits, costs, and challenges of developing a renewable charging system.

The electric grid

Mississippi Power conducted distribution studies to ensure that our lines can handle the load from vehicles. Research on typical distribution lines indicates the capacity to handle electric vehicles. Also PEVs often will charge during the night when there is excess capacity. We encourage you to charge your vehicle at night and even offer a rate that passes those night time savings onto you. According to the EPRI-NRDC report regarding Electric Vehicles, "there is an abundant supply of electricity for transportation; a 60 percent U.S. market share for PHEVs would use 7 percent to 8 percent of grid-supplied electricity in 2050."

Vehicle to Home (V2H) and Vehicle to Grid (V2G) are technology options that use the energy stored in a PEV's battery for purposes other than driving. V2H uses the energy stored in a PEV's battery to power the PEV owner's home. A PEV owner could utilize V2H when his power is interrupted or during demand response events. V2G provides power to the electric grid from the stored energy in the battery pack. V2G allows the utility to use the vehicle battery power for regulation services, peak demand reduction, or to meet sudden demands for energy. Southern Company is researching both types of technologies to better understand and utilized the benefits they provide to our customers.

Your vehicle manufacturer may send a request to you asking for permission to inform us of your vehicle purchase. This information helps us ensure your neighborhood transformer is prepared to deliver the electricity you'll need, especially if your neighbors choose to charge vehicles at the same time.
