Google is pressing ahead with a major expansion in The Dalles, where the company opened Oregon's first big corporate data center in 2006.
Citing plans submitted to the city, The Oregonian newspaper reports the new data center would be 164,000 square feet - significantly larger than the buildings now operated by Google in The Dalles.
The company was drawn to the Columbia River Gorge city by tax incentives and cheap electricity. It has 150 employees and contractors at a pair of 94,000-square-foot data centers.
City planning director Dick Gassman says the company hasn't given a timetable to start construction.
