California bill aims to transform electric vehicles into mobile power sources for grid and homes.
A Proposed California Bill Aims to Make Electric Vehicles More Powerful and Versatile
A proposed California bill is generating buzz as it seeks to revolutionize the capabilities of electric vehicles (EVs). If passed, the bill would require all new EVs sold in California after 2030 to be “bi-directional,” meaning they would not only contribute power to vehicles but also provide energy to the grid and households.
Authored by Sen. Nancy Skinner (D-Berkeley), Senate Bill 233 aims to relieve strain on the state’s electrical grid and help meet California’s ambitious goal of being 100 percent carbon neutral by 2045. Sen. Skinner emphasizes the potential of EVs to act as mini power plants on wheels, especially in the face of climate change impacts such as heat waves, wildfires, and power outages.

The bill has already passed the Senate and is now scheduled to be heard in the Assembly’s Appropriations Committee on August 24. Currently, EVs make up 20 percent of California’s new vehicle sales, a significant increase from five years ago. However, the cost of EVs can vary greatly, with typical one-way EV chargers being more affordable, starting at around $1,000.
On the other hand, bi-directional chargers, which enable power transfer between the EV and the household, are pricier, averaging around $4,000 and going up to nearly $10,000 for faster-charging and luxury models.
Currently, only a few EV models, such as the Nissan Leaf and Ford F-150 Lightning, offer bi-directional charging. However, other manufacturers are exploring the integration of this technology into their newer models.
While the concept of bi-directional charging holds promise, the bill’s analysis conducted by legislative staff highlights the complexity of transferring electricity from EVs back to the grid. Commercial use of this technology does not currently exist, and major infrastructure changes would be required to accommodate bi-directional capabilities.
Furthermore, concerns about the reliability of California’s electric grid have been raised. A study by the University of California–Berkeley suggests that utility companies’ slow pace in upgrading the grid could hinder the state’s EV adoption plans due to increasing electricity demand. The estimated cost for necessary grid upgrades ranges from $1 billion to potentially over $10 billion for utility companies.
Some critics argue that the bill’s provisions may not be feasible for consumers. Energy consultant Ronald Stein points out that the high cost of living and inflation already make EVs unaffordable for many individuals. The addition of bi-directional charging could further increase the financial burden. It’s worth noting that the bill does not mandate consumers to switch to EVs, but rather aims to facilitate the transition to clean energy.
As the bill progresses through the legislative process, the future of bi-directional EVs in California remains uncertain. However, the potential benefits of these vehicles in terms of grid stability and carbon neutrality make this an exciting development to watch.
