### Farming

Quincy has long had an agricultural economy, which was enhanced by irrigation made possible with the Grand Coulee Dam. Major crops include potatoes, wheat, and timothy grass. Orchards and vineyards are also displacing lower-value crops in the Quincy Valley.
An investigation into the dumping of toxic waste onto farmland and its relabeling as fertilizer in Quincy was the subject of the 2001 book Fateful Harvest.

### Technology

Technology companies such as Microsoft, Yahoo!, Dell and Intuit have located large data centers within the Quincy area since 2007. Microsoft's Columbia Data Center, built starting in 2006 and expanded several times, is said to be the world's largest data center. The centers, attracted to the area because of its abundant and cheap hydroelectricity, have been criticized for dodging fines from the Grant County Public Utility District for overusing electricity and for creating air pollution through their diesel backup generators.
The data centers are incentivized by tax credits offered by the state of Washington to stimulate economic development in the city. Two additional electrical substations are being built to handle expected demand from current and future companies.
