BIDIRECTIONAL Act introduced in US Senate to promote electric school buses feeding grid

A new bill introduced Friday by US Senator Angus King of Maine could unlock the true potential of electric school buses and provide stability to communities in need. The BIDIRECTIONAL Act would “create a program dedicated to deploying electric school buses with bidirectional vehicle-to-grid (V2G) flow capability.”

Zero-emission electric school buses are being deployed nationwide as state leaders and school districts look to protect the children and communities they vow to serve. New information shows school districts that replace just one diesel school bus with an electric one can reduce toxic emissions by 54,000 pounds a year.

However, the benefits of electric school buses don’t stop there. The massive batteries they utilize also make perfect energy storage devices. Several automakers and charging companies are experimenting with vehicle-to-grid (V2G) technology that enables vehicles to send energy back to the grid.

Manufacturers of electric pickup trucks (like the Ford F-150) and other EVs have dived into bi-directional charging, but this technology makes even more sense for electric school buses because they have large batteries that sit most of the day. To illustrate this point, Thomas Built Buses partnered with Proterra to show two electric school buses can send 10 MWh total back to the grid, enough to power around 600 homes.

Senator King wants to capitalize on this ability with the BIDIRECTIONAL Act to promote the widespread deployment of electric school buses with V2G capability to improve community stability.

The BIDIRECTIONAL Act is designed to accelerate adoption of EV school buses while using them for more than just a ride to school.

According to Senator King, the BIDIRECTIONAL Act will:

  • Establish a Department of Energy (DOE) program to roll out electric school buses designed with V2G capabilities in communities that need them most.
  • Require the DOE to report on current V2G initiatives (such as Thomas Built and Proterra) while also requiring electricity providers to consider bi-directional integration.

Senator King commented on the initiative, stating:

Vehicle-to-grid school buses are another common sense tool that can help to create a reliable grid, promote clean energy, and cut costs for local towns and school districts.

Adding:

The BIDIRECTIONAL Act will assist school districts across Maine and America transition to electric buses and make sure these vehicles provide greater stability to their communities. Combined with electric bus investments in the Inflation Reduction Act, this will be an important step towards unlocking America’s clean energy future. It’s a simple, win-win bill and I hope it can get bipartisan support across Congress.

Several major electric school bus makers and other organizations are backing the bill, such as Blue Bird, Highland Electric, Lion Electric, Nuuve, Proterra, and Xcel Energy.

Electrek’s Take

Electric school buses with V2G are a no-brainer. Not only will they reduce greenhouse gas emissions, protecting the communities they serve, but they can also play a key role in providing energy stability to communities in need.

The Environmental Protection Agency (EPA) just announced it would be nearly doubling EPA clean school bus program funding to $965 million in its initial round . Federal funding is a huge first step, but strong state leadership is also necessary if these clean machines are going to become widely adopted. Virginia, for example, just surpassed 500,000 electric school bus miles driven thanks to a state initiative to roll out 13,0000 electric school buses in 2019. They now have the nation’s second largest fleet of electric school buses.

I believe Senator King is wise in proposing this bill. I truly believe electric school buses have unlimited potential waiting to be unlocked, and the BIDIRECTIONAL Act can do just that.
