General Motors is considering investing more than $4 billion in two Michigan plants to boost its electric vehicle production capacity, according to sources and documents made public on Friday.

GM has proposed building a $2.5 billion battery plant near Lansing with partner LG Energy Solution, the documents show.

The largest U.S. automaker is separately considering a $2 billion overhaul of its Orion Township assembly plant north of Detroit to build next-generation electric vehicles. The total investments could top $4 billion, a source familiar with the plan told Reuters. Documents posted by the city of Lansing show GM is considering building a battery cell manufacturing plant in nearby Delta Township that could employ 1,700 people by 2028. The Lansing City Council is expected to consider the proposal on Monday.

The joint venture battery plant would be 2.5 million square feet and is on land currently owned by GM, the documents say, adding that “the battery cell production facility will generate significant economic activity throughout Michigan.”
