JEFFERSON CITY -- Supporters of the concept of adding tax incentives for data centers to an economic development bill being debated in the special session of the Legislature continue to put pressure on Gov. Jay Nixon to expand his call.

Yesterday, the Missouri Chamber of Commerce released a study that indicates that just one large data center in the state could produce $40 million in tax revenue for Missouri in its first five years, based on construction and operation costs.

Data centers are the large server farms that store information sent over the Internet for major companies. Several major companies are considering Missouri for data centers that could cost more than $1 billion each, according to those pushing to have the tax incentives added to the bill that gives $150 million in incentives to Ford and other automotive manufacturing companies over 10 years.

Nixon has been unwilling to consider the incentives for data centers.

"If the reason for calling the special session in the first place was to create jobs and secure additional state revenues, then there is a strong case for including data center incentives," said Chamber president Dan Mehan, in a statement.

The special session continues today.
