Google Inc. will expand its operations at the Mt. Holly Commerce Park in Berkeley County. The additional $600 million investment at the data center site brings Google's total investment to over $1.2 billion.

The announcement aligns with Google's goals to provide the best possible user experience. The data center in Berkeley County houses computer systems and associated components that support services such as Google search, Gmail, Google+ and YouTube. The company is growing capacity to meet demand for Google's services.

Google first announced plans for a South Carolina data center in 2007 and made an initial investment of $600 million to get the center up and running. In November 2010, Google announced plans to construct a second building at the site, which is now in operation.
