GM plans to invest $300 million into the Tonawanda Engine Plant to produce parts for electric vehicles, according to the UAW's tentative agreement between the UAW and General Motors.

The investment will allow it to add drive unit production for GM's electric vehicles as the automaker transitions from gasoline-powered vehicles. The automaker has set a 2035 deadline to shift all of its products to zero-emission electric vehicles. 

The Tonawanda plant builds engines and power trains for pickup trucks and SUVs like the Cadillac Escalade and GMC Yukon. There are more than 900 people currently employed.    

The agreement also protects a previously planned $154 million investment for the Lockport GMCH, where they will produce electric vehicle stator modules.
