For V2G to scale the economics for the players must be convincing. The potential for earning, saving money or improved energy resilience depends on geographic, regulations and tariffs. The earnings/savings can be shared e.g. with the EV owner to lower the cost of EV ownership.
Some examples demonstrate the superior economics/value of V2G:
Lower CO2 emission
Allow for more renewables
Increase grid and energy resilience and lowers cost of grid upgrades
Transmission: Frequency Regulation in Denmark $1,830/year = $14,640 over lifetime
Distribution: Voltage support, congestion relief, deferral of grid investments. Value varies per DSO.
Behind the Meter
Export 10kWh energy to house at peak hours -> $1,100/year California = $8,800 over lifetime of EV
Value of emergency power = 🙂🙂🙂 (individual)
10 kW reduction of peak $400/month** @ 6 months = $2,400/year * 8 = $19,200 over lifetime of EV
**depends on grid operator, building load profile and number of EVs
Grid operators will be competing with the behind the meter applications. Only if they offer attractive tariffs will they be able to tap into the great potential of V2G aggregated EV grid services.
