Honda Power Equipment Manufacturing Inc., a division of American Honda Motor Co. Inc., is investing $8.5 million into its Swepsonville facility and planning the production of a new generator as it celebrates the plant's 30th anniversary on Wednesday.

The company didn't disclose details about the expansion, but will be holding a media event and tour on Wednesday at the facility. The plant was opened in 1984 and produces a wide variety of outdoor power equipment including lawn mowers, string trimmers, snow blowers, water pumps and general purpose engines.

Honda Power Equipment Manufacturing employs more than 620 full-time associates and 340 contract associates at the plant, which produces more than 2 million products annually.

Honda officials said they have invested more than $250 million — including a $30 million expansion a decade ago — at the location over the past 30 years, enabling it to produce more than 27 million power products.
