In the study's "Outcome" section, the firm said Gestamp estimates it will invest up to $100 million and create up to 400 manufacturing jobs.
State Commerce Secretary Keith Burdette has said Gestamp's investment could eventually total $150 million.
When Gov. Earl Ray Tomblin announced in April that Gestamp would reopen the plant, he said Gestamp could eventually employ 700 people.
BT ProjectPoint said, "The incentive package from West Virginia state and local jurisdictions includes: State Economic Opportunity Tax Credits, Manufacturing Investment Tax Credits, Manufacturing Property Tax Adjustment Tax Credits, Payment in Lieu of Tax (PILOT), Foreign Trade Zone Exemptions, Freeport Exemptions, the Governor's Guaranteed Work Force Training Program, a $2.5 million forgivable relocation loan and a $15 million loan from the West Virginia Economic Development Authority."
"Once Gestamp meets hiring and investment goals, the company's incentives and tax savings could eclipse an estimated $55 million," the firm said.
The study doesn't mention the city business and occupation tax break approved by South Charleston, which will save Gestamp an estimated $10 million over 20 years.
Ray Park, who owns the plant property, completely renovated the 922,000-square-foot building after the former tenant ceased operations in 2006.
South Charleston Mayor Frank Mullens said on Tuesday that Gestamp is on schedule to get up and running this month.
