Clean Energy Basics Vol. 4
Summary
Vehicle-to-Grid (V2G) is the flow of renewable energy from an electric vehicle’s (EVs) battery back into the electric grid. V2G is common with EVs nowadays and provides a means of incorporating renewable energy into the grid. There are benefits for both utilities and local consumers with V2G technology. With V2G charging you sell energy back to your utility. Reduced energy costs and decarbonization are also notable achievements of V2G.
Key Takeaways
- Vehicle to Grid (V2G) allows for an electric vehicle to emit power from its battery into the grid
- Extra power from V2G adoption supplies your home and lowers your energy costs in the long run
- V2G adoption increases renewable energy integration and decreases carbon emissions
What is Vehicle to Grid (V2G)?
Vehicle to Grid (V2G) is a term that refers to an electric vehicle’s (EV) ability to send power back into the grid. EVs charge their batteries through renewable and traditional energy sources. Later, this same stored energy can power the grid. The primary benefit of V2G technology is the ability to use vehicles as an emergency and distributed power source. V2G also lowers power consumption through a better power balance and allows you to sell your energy back to your utility.
The increased adoption of EVs and EV charging stations enable V2G capabilities. Additionally, policy changes like FERC Order 2222, are paving the way for V2G, DERs, and other renewable energy sources to become more common in the future.
How does V2G Fit into the Energy Ecosystem?
V2G fits into the larger energy ecosystem by providing a source of distributed, rapidly accessible energy into the grid. This is particularly important because it allows for a single EV battery to power more than just the EV it’s connected to, and acts as a backup power source. V2G also eases grid load from areas struggling to meet demand during times of peak energy usage.
V2G also functions to compensate for problems in the grid. Outages and large-scale weather events can be less harmful because of V2G technology. During an outage, V2G technology powers homes, businesses, and critical buildings while other power sources are down.
How does V2G technology Help Me?
V2G technology means that you will be able to save more money by selling your power back to the grid. This will also lead to more reliable power in your home and workplace. Using renewable energy also leads to environmental benefits. V2G is a win-win for both you and your local utility, but most importantly, the environment.
