TEP’s emphasis on energy efficiency programs has significantly reduced our need for new resources. Through the end of this year, our customer-friendly programs will have reduced our peak demand by more than 300 megawatts – enough to power nearly 167,000 homes.

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.
