Arizona has some of the most ambitious energy efficiency goals in the nation. Over the next 5 years APS plans to work with our customers to achieve energy savings of over 2.8 million mWh - or enough energy to provide power to all households in a city the size of Glendale for just over 2 years - through our energy efficiency programs.  These programs will help you save money, while reducing the need for new power plants in the future.
arizona energy efficiency standard 
In 2010, the Arizona Corporation Commission established one of the most aggressive energy efficiency programs in the nation. The policy requires us to achieve savings equivalent to 22% of retail sales by 2020.
By the end of calendar year 2012, our goal under the standard was to achieve savings equivalent to 3.0% of retail sales with energy efficiency. Our actual performance was slightly higher than that goal, achieving savings equivalent to 3.2% of sales.
energy efficiency plan
APS files annual energy efficiency plans with the Arizona Corporation Commission for approval. Our current plan calls for the continued implementation of our energy efficiency programs throughout 2013 in order to achieve savings through the programs equivalent to 5.0% of retail sales by the end of 2013.

APS currently has programs for both residential and business customers that include rebates for installing energy efficient equipment, training and technical support to help you identify and understand energy efficiency opportunities, and information about how you use energy to help you become more energy efficient.
