Our long-term plan to shift from coal power to alternative sources really started taking shape this year. We reduced our use of Unit 1 at the coal-fired Springerville Generation Station by 50 percent. We also agreed to the closure of a coal-fired unit at the San Juan Generating Station in New Mexico and began planning for the potential elimination of coal as a fuel source at our H. Wilson Sundt Generating Station in Tucson by 2017.
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.
