    Texas grid giant Oncor collaborating with Toyota on Vehicle to Grid research pilot

    The rising tide of vehicle electrification in the U.S. could push peak demand to unprecedented heights, requiring multi-billion-dollar expenditures across various grids nationwide. In California alone, a report by the Smart Electric Power Alliance anticipates some 4.9 GW in EV load expansion by 2030.

    So the potential vehicle to grid (V2G) technology offers a counterpunch to that coming force.

    Texas-based electric transmission owner Oncor Electric Delivery will explore the V2G possibilities under a first-ever collaboration with Toyota Motor North America. The pilot project will enact and examine V2G technology allowing EVs to flow some energy from the battery back into the electric grid.

    The effort will be led by Toyota’s Electric Vehicle Charging Solutions team. It is the auto maker’s first collaboration with a public utility in the U.S.

    “Electrification is coming, and it’s Oncor’s job to build a safer, smarter, more reliable electric grid that can enable the needs of our customers, the state of Texas and the ERCOT (Texas grid) market,” Jim Greer, Oncor executive vice president and chief operating officer, said in a statement.

    The research partnership with Toyota will begin with work at Oncor’s research and testing microgrid in south Dallas, near Toyota North America’s nearby national headquarters. The microgrid is actually comprised of four interconnected microgrids that can be controlled independently, but also in parallel, tandem and combined into a single microgrid.

    “Our collaboration with Oncor is an important step for us to understand the needs of utilities, as we plan to work closely with them to ensure every community can embrace Toyota’s shift to electrified vehicles,” Christopher Yang, group vice president of Toyota Electric Vehicle Charging solutions team, said in the same release.

    The second phase of the research project next year will include a V2G pilot where testing is conducted with battery electric vehicles connected to homes and businesses in Oncor’s service territory.

    The line of communications between EV makers, utilities and other key facets of the transportation sector may still be in its infancy stage, according to many close to the movement. The unpredictable nature of power demand and grid infrastructure siting to respond to that are major hurdles of the moment.

    “The conversation is very challenging,” Dave Schaller, industry engagement director of the trucking-supported North American Council for Freight Efficiency, said during an October presentation at the T&D World Conference and Exhibition in Charlotte. “Very strategic questions need to be asked.”

    Pilots such as one involving Toyota and Oncor will possibly help answer some of those questions, both sides hope.

    Like most major automakers, Toyota promises to go mostly electric in the coming decades. It’s first mass-market battery electric, the bZ4X, went on sale this year in the U.S. and Canada. The first Lexus BEV, the RZ 450e, is scheduled to enter the market in 2023.
