Indiana's manufacturing sector is set for some big news. General Motors Co. (NYSE: GM) executives and Governor Mike Pence will take part in a major announcement Tuesday afternoon at the automaker's Fort Wayne Assembly plant. The announcement is set for 1:15 p.m. at the Roanoke facility.

Last fall, GM executives ramped up efforts to secure an investment of up to $1 billion in the plant, including going before the Allen County Council in hopes of lining up tax breaks for a potential facility expansion.

At the time, officials said, while the investment may not create jobs, it would help retain 4,000 existing positions and serve as an investment in the operation's long-term future.

Governor Pence attended January's North American International Auto Show in Detroit. During the trip, he met with GM Chief Executive Officer Mary Barra and took part in announcements from Italian auto suppliers involving more than 100 jobs in Speedway and Anderson.

The United States Environmental Protection Agency recognized the plant last month for its commitment to onsite renewable energy. The automaker says its generation of 53 million kilowatt hours of green power represents the equivalent electricity use of more than 5,000 American homes each year.

The plant produces the regular and double-cab Chevrolet Silverado and GMC Sierra.
