Step in to see big changes in the energy mix

Tucson's demand for power continues to grow. Over the next decade, TEP is expecting 50,000 new customers as well as annual increases in our community's peak energy demand. We're making plans to satisfy this demand while gradually reducing our reliance on coal. So what will our fuel mix look like in four years? How about in 2028? Let's hop in the time machine to find out.

You should know that these charts are based on TEP's 2014 Integrated Resource Plan, which treats energy efficiency (EE) like any other energy resource. For that reason, they include both the energy TEP delivers and the energy we won't have to produce thanks to our EE programs. That's why the percentages shown for other resources — like renewable energy — are smaller than their share of our actual energy mix. So rest assured that TEP is on track to meet or exceed Arizona's Renewable Energy Standard, even if the percentages shown here appear to lag behind those annual goals.
