PG&E and BMW of North America Expand Collaboration by Testing Vehicle-to-Everything Technology That Will Improve Grid Reliability and Help EV Customers Lower Their Electric Bills by Exporting Power Back to the Grid During Peak Demand Periods
As electric vehicles (EVs) become more prevalent, with approximately 40% of all EVs in the United States driving on California roads, Pacific Gas and Electric Company (PG&E) and BMW of North America (BMW) are collaborating to test how vehicle-to-everything (V2X) technology can serve as a solution to offset growing demand on the power grid, improve reliability for electric customers, and maximize the usage of renewable energy. In addition, V2X technology could eventually enable customers to use their vehicles as backup home generation when needed.
The V2X testing is taking place at PG&E's Applied Technology Services (ATS) Lab in San Ramon and is the focal point of an extended partnership to advance V2X technology and explore the utilization of EVs as a flexible grid resource. The collaborative testing builds on the momentum of the ChargeForward smart charging program, which was announced in 2015 and offers PG&E customers who drive a BMW EV, incentives to align vehicle charging with renewable energy to help support the overall sustainability of the electric grid.
"Electric grid sustainability is becoming an increasingly complex challenge across the U.S.," said Adam McNeill, Vice President, Engineering, BMW of North America. "That's why we started our ChargeForward program in 2015, to connect our vehicles, our customers, and the grid. V2X takes smart charging to the next level, exploring how EV batteries can be used for backup generation and other grid services. We're excited to continue pursuing additional customer benefits while helping make the grid more dependable and sustainable."
V2X technology will someday empower EV drivers to return excess stored energy from their vehicle batteries back to the grid in exchange for compensation, presenting an ideal response to high-demand power conditions and a key solution for grid stability and resiliency. Additionally, V2X technology could play an important role in increasing the amount of greenhouse gas (GHG)-free resources powering the grid by storing solar and wind energy generated during the day to supplement the availability of clean energy during the peak evening demand period and overnight.
"The utility and automotive industries are creating a transformative clean energy future together. At PG&E we are working with partners like BMW to unleash the full potential of EVs to enhance grid resilience and reliability for our customers, while reducing carbon emissions in our hometowns" said Aaron August, PG&E Vice President, Utility Partnerships and Innovation. "Clean-powered EVs are vital to the battle against climate change. Using V2X technology to create virtual power plants from EVs can help utilities like ours meet peak electricity demand without the need for non-renewable energy resources. With smart, managed bi-directional charging, we can decarbonize our planet at a lower cost to our customers."
The pilot is assessing how a typical home could maximize its renewable energy usage by switching between EV battery stored renewable energy and grid-provided renewable energy. The EV battery charges when the renewable energy mix on the grid is highest and the battery discharges throughout the day to support the household load. Results show that a vehicle-to-home connected EV is capable of providing roughly double the amount of renewable energy that a typical California household would be able to use on an average day, significantly increasing customers' ability to use more green energy on a daily basis. Testing also offers insights on how V2X vehicles perform under real-world scenarios, taking into consideration vehicle functionality and driver behavior to ensure that EVs can be used as a viable grid resource while still meeting customer needs.
PG&E and BMW will continue collaborating to better understand how these learnings can be applied to consider other customer and utility benefits.
ChargeForward Program
This expanded partnership, focused on V2X testing, is a direct result of the success of ChargeForward. Conceived eight years ago, and now in its third pilot phase, BMW and PG&E were the first to offer customers cash incentives for maximizing renewable energy by optimizing their EV charging times to support the overall reliability of the electric grid. It is available to all BMW battery and plug-in EV drivers in Northern and Central California who are also PG&E residential electric customers.
This last year showed that by aligning charging with renewable energy, BMW drivers helped the grid generate and support more clean energy. In California 1.4 million miles were powered by 100% renewable energy in 2022.
What's next?
BMW and PG&E have agreed to extend their partnership until March 2026 with a focus on smart charging testing. In the next stage of this collaboration, BMW and PG&E will work together to continue testing V2X-enabled vehicles, specifically vehicle-to-grid (V2G), in a field trial at BMW Group Technology Office USA located in Mountain View, Calif. BMW will develop a test fleet of V2X vehicles that will be used in day-to-day operations and serve as a grid resource to help integrate renewable energy and balance the grid. This field test will evaluate how V2X technology can be used for advanced use cases that can be commercialized in future years and help support renewable integration on a neighborhood level to increase grid reliability on a larger scale.
PG&E plans to share more in the coming weeks on its V2X testing collaborations and the work the company is doing to maximize the benefits of EVs. Media interested in learning more or visiting the EV Test Bay at PG&E's ATS Laboratory are encouraged to contact PG&E's communications department.
