TEP is now producing enough energy from solar, wind and biogas resources to power more than 136,000 homes, with energy storage that helps us use these resources more reliably. We’re also getting nearly as much power from natural gas as we are from coal, proof that our long-term resource diversification plan is generating real dividends for our environment while maintaining reliable and affordable service to our customers.

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.
