It would also make sense that since SI prefixes are fairly well known and since Giga- is the largest that most consumers are familiar with and associate as being large, it's a way for them to name a plant so that it has obvious technological associations, while still allowing for growth (Terafactory, Petafactory) as both the need for manufacturing capacity and the public's understanding of bigger SI prefixes change.
