Less than one year after Google launched its Oklahoma data center, the company is reportedly ready to expand capacity at its site in an industrial park in Mayes County, according to the Associated Press.

The state’s governor Mary Fallin and Google officials were expected to announce the expansion plans on Wednesday morning, the AP reported. The governor’s office did not respond to a request for comment in time for publication.

The company’s existing data center at the site came online in the fall of 2011. Google said it was investing US$600m in the Mayes County campus, although it was not clear whether the figure included the cost of the upcoming expansion.

The company first announced it would build a data center in Oklahoma in 2007. The plans were put on hold, however, the following year.

According to Google, the reason for freezing the project was a determination that new capacity was not necessary at that time. The project resumed in 2010.

The reason Google chose Mayes County and the MidAmerica Industrial Plark was the right combination of energy infrastructure, land and workforce availability, according to the company’s website.

“Additionally, the team from the local community that welcomed us has worked exceptionally hard throughout the selection process,” Google said.

This is the second expansion of Google’s data center infrastructure reported this week. Earlier, the company said it had kicked off construction of a new data center in Taiwan as part of its infrastructure program in Asia, which also includes new builds in Hong Kong and Singapore.

Google talks about 11 of its data centers publicly, including the three ongoing construction projects in Asia, six sites in the US and two in Europe.
