Exploring phase one findingsDuring the first phase of ChargeForward, PG&E sent signals to BMW requesting a load reduction on the grid of up to 100 kilowatts (kW). In response to these demand response signals, BMW selected vehicles for delayed charging - up to one hour delay per day - based on drivers' needs. Participants could choose to opt-out of participation as desired if they needed to begin charging their BMW i3 immediately. BMW supplemented the smart charging of these vehicles with a solar-powered energy storage system made from "second life" EV batteries - lithium-ion batteries from old BMW MINI E demonstration EVs - as a back-up to support the grid during these demand response events as necessary. Results from the first phase of the pilot with the BMW i3 include:
- Nearly 100 BMW PG&E customers in the greater San Francisco Bay Area who own BMW i3 EVs participated in the pilot.
- Satisfaction has been high with 92 percent of participants indicating they are very satisfied with the pilot and 86 percent would likely recommend it to family or friends.
- A total of 192 demand response events took place between July 2015 and October 2016, with events scheduled through the end of 2016.
- In 94 percent of the demand response events through October 2016, BMW successfully reached the full grid load reduction of 100 kW requested by PG&E.
- By August 2016, more than 19,000 kilowatt-hours (kWh) were shifted as a result of ChargeForward events - enough to power the electricity for two homes over one year - avoiding costly and carbon-intensive electricity generation.
Participants can earn up to $900 for participating in this 24-month pilot, with all participants receiving a $300 initial incentive soon after the program launches. The total amount earned over the two years depends upon individual participation in charging events. Customers may also have the opportunity to earn additional incentives for participating in short-term charging tests, or sub-pilot projects, that may occur during the 24-month period.BMW ChargeForward pilot goals The goal of the pilot is to make smart charging more beneficial to the grid and more rewarding to participating drivers. The ChargeForward program is expected to help improve grid reliability and support the integration of renewable energy. By sharing the benefits of this optimization with EV drivers through incentives, smart charging also helps reduce the total cost of EV ownership - encouraging EV adoption.
