MADISON - Asian electronics giant Foxconn is considering investing at a second site in Wisconsin — this one in Dane County, according to a half dozen knowledgeable sources.

The investment in Dane County could come in a separate business from the massive flat screen television plant that Foxconn Technology Group has already committed to building in southeastern Wisconsin.

No offers have yet been made by the Taiwanese company and there are no guarantees any will be.

“That’ll probably clear up in the next 45 days,” said one source familiar with the potential project. "It's good to be in play."

So far, a clear goal has not emerged for the potential facility, but sources gave several possibilities, including a research and development site; an operation connected with medical imaging; and a business related to wearable devices that could track a consumer's vital statistics.

"It's a moving target," a source said of the Foxconn inquiries.

Lawmakers are already considering an unprecedented package of up to $3 billion in state subsidies and exemptions from environmental rules to bring the flat screen plant and thousands of jobs to either Racine or Kenosha counties. The Assembly Committee on Jobs and the Economy will hold a hearing Thursday on legislation to approve the state's agreement in principle with Foxconn on the up to $10 billion southeastern Wisconsin factory.

Sources said that this agreement with Foxconn has given Wisconsin a leg up in competing for other investments from the company, such as the potential one in Dane County.

At a news conference Wednesday, Walker said the Dane County site was still "speculation," although his comments indicated it was more than that.

"We're a ways off, as we get closer to that, we'll give you information about that," the governor said.

Walker was joined at the Capitol by the South Korean ambassador to the United States, Ahn Ho-Young, to discuss business with Asia. The governor will lead a trade mission to Asia from Sept. 8 to 16, first visiting Japan for a conference with other Midwest visitors and then heading to South Korea.

In separate comments to Fox 6 Wednesday, U.S. House Speaker Paul Ryan of Janesville said he also expected more than one Foxconn facility in Wisconsin.

"We do anticipate there's going to be more than just this one location in (the) Racine-Kenosha area," Ryan said.

The Milwaukee Journal Sentinel has previously reported on how Foxconn executives have visited Dane County over the past two months, meeting with University of Wisconsin-Madison researchers and with startup companies from the University Research Park.

But they've done more, investigating sites in the Madison area for a possible company location, sources said.

"It would not be a surprise that they are hoping to do a number of projects," one source said of Foxconn.

Fitchburg Mayor Jason Gonzalez confirmed that Foxconn executives visited his city and toured Placon, a local manufacturer that could have parcels for potential development.

"I would say that there has been interest in Fitchburg from them," Gonzalez said. "They did get a chance to see Fitchburg and some of the (greenfield sites) we have."

Like several other sources, Gonzalez pointed to UW-Madison as an important factor for Foxconn in considering Dane County. In addition to the research there, UW is also an alma mater for executives and scientists in Taiwan who are connected to Foxconn, sources said.

"Frankly, there's a strong alumni connection in Taiwan," Gonzalez said of UW.

Judd Blau, village board president for the Village of DeForest in northern Dane County, said he had been told that DeForest is a potential site for Foxconn. Blau cautioned that he wasn't aware of any visits to his village by company executives.

Though significant, the potential Dane County project is not expected to reach the staggering size of the one in Racine or Kenosha and likely would use existing economic development incentives without any legislative changes needed, sources said.

The Walker administration is seeking to provide up to $3 billion in cash payments to Foxconn over 15 years if the plant in the Racine-Kenosha area reaches the upper employment goal of 13,000 workers.

Tim Bartik, a senior economist at the W. E. Upjohn Institute for Employment Research in Kalamazoo, Mich., said that amounted to annual payments of $15,000 or more per job. That's six times the average national per job incentive of $2,457 that comes from a database that Bartik maintains on such subsidies.

"It seems to me that the burden of proof should be on the state to show that the project is transformational enough to justify a very high cost per job-year," said Bartik, who also questioned whether many of the workers would end up commuting from Illinois.

Walker and other GOP leaders have argued that the deal makes sense because of the technology and advanced practices that Foxconn would bring to the state, as well as potential secondary investments like the one in Dane County.

President Donald Trump said this week that Foxconn's U.S. investment could reach as much as $30 billion. In a statement, Foxconn avoided giving a dollar figure but confirmed that it could make other investments.

"Our investment in Wisconsin will be the first of a series of facilities we will be building in several states as part of a robust electronics ecosystem we will be creating in the United States," the statement reads. "We have not yet announced our investment plans for other sites."

Sources said they're uncertain if other states are competing against Dane County for the potential project there.
