Powering Economic Development

UniSource powers Arizona’s economy by providing safe, reliable and affordable natural gas and electric service to communities throughout Arizona. Our sustainable and flexible energy portfolio, generous energy efficiency incentives and attractive commercial rates encourage existing businesses to expand and attract new employers and jobs to the Grand Canyon State. Our value proposition coupled with our customer-centric approach to service position your company for growth and success.

Discounted rates for new, expanding companies

UniSource’s Economic Development Rate (EDR) is designed to attract new employers and retain and support businesses wishing to expand their operations in our service territories. Electric bill discounts are available for up to five years for new or existing businesses that meet minimum load and job creation requirements included in Arizona’s Quality Jobs or Qualified Facility tax credits.

For example, businesses that expands operations into existing vacant facilities and meet certain requirements could receive a 30 percent discount on a portion of their monthly electric bill for the first year.

New and existing customers taking service under this rate must provide written documentation to qualify for the discount. EDR availability is limited to a total customer load of 50 megawatts (MW).

Businesses of all kinds can profit from these savings. Energy-intensive businesses, such as manufacturers, mining operations and data centers, can especially benefit from UniSource’s affordable rates and highly reliable service.

Here’s an example of how a company opening new facilities in our service territory can greatly reduce their energy costs through the EDR. In this scenario, a manufacturer on our Large Power Service Time-of-Use (EILPST) rate has a peak annual demand of 3 MW, an average usage of 1,620 megawatt hours (MWh) and a load factor of 75 percent.

Year Normal Rate Rate with EDR Cumulative Annual Savings
1 $114,413 $91,530 $274,591
2 $114,413 $97,251 $480,534
3 $114,413 $102,971 $617,829
4 $114,413 $108,692 $686,476
5 $114,413 $111,552 $720,800
