Intermountain Power Project (IPP)
One of the main sources of income for Delta is a power plant operated by the Intermountain Power Agency, known as the Intermountain Power Project or I.P.P. It is also referred to as Intermountain Power Service Corporation or I.P.S.C. This coal-powered power plant supplies power for much of Los Angeles county in California. The plant was originally designed for four units, but only two have been built. Each unit produces 900 megawatts of electricity.

Brush Wellman
Brush Wellman is a mine and refining plant located at one of the few sources of concentrated beryllium in the world. The plant is a mill and finishing facility for beryllium, a high-strength, lightweight metal used in military, aerospace, and medical industries. The ore for the plant comes from Brush Wellman's mine, located in the Topaz-Spor Mountains, 50 miles west, which is North America's only developed source for the metal. The facility is located here due to the remoteness of the area, as beryllium dust is highly toxic, and the proximity of a large source of power: the Intermountain Power Project.

Graymont Lime
Graymont Lime has a plant in the Cricket Mountains, about 32.5 miles southwest of Delta. It is one of the 10 largest lime plants in the United States. It was previously owned by Continental Lime which was purchased by Graymont Lime.

Alfalfa
Alfalfa hay is the main crop of the Delta area. Because of Delta's dry climate, the farmers are able to control the alfalfa hay's moisture when it is baled. This is very important to prohibit mold growth.

Dairy
Delta is home to many dairy farmers who may ship the milk out of the county.

Cosmic Ray Center
Delta is home to the Lon and Mary Watson Cosmic Ray Center, the main staging area for the Telescope Array experiment.

Fossils & Minerals
A great attraction of Millard County's economy is the digging of fossils. Trilobite fossils are relatively common in the region west of Delta (part of the House Range's Wheeler Shale). A number of local companies maintain fossil dig areas where they allow visitors to dig their own fossils for a small fee.

Near Delta is a mountain called Topaz Mountain which derives its name from the topaz that is abundant in the area. Other minerals and rocks that are prevalent near Delta include obsidian, opal, and geodes.
