Michigan has awarded tax credits so battery makers for electric and hybrid vehicles will open factories in the state.
Four projects were approved Tuesday by the Michigan Economic Growth Authority. One is contingent on another tax credit being passed by the Legislature.
Some plant locations aren't finalized.
But Milwaukee-based Johnson Controls-Saft Advanced Power Solutions says it plans to open a plant in Holland, Mich.
And A123 Systems Inc. of Watertown, Mass., plans to start a plant in Livonia.
Another winner of a credit is KD Advanced Battery Group, a joint venture involving Dow Chemical, Kokam America and Townsend Ventures.
Korean-based LG Chem-Compact Power also plans a project if lawmakers pass an additional tax credit.
