The Arizona Corporation Commission’s 2010 energy efficiency rules catapulted the state to the front of the energy efficiency industry, according to the Southwest Energy Efficiency Project.
The rules require utilities to save a total of 22 percent of the energy used in electricity retail sales by 2020, with incremental goals set each year prior, adding up to that amount. These savings are measured in megawatt-hours (MWh), and indicate that a company has used fewer units of energy than it had in the previous year.
Arizona’s utilities are performing extremely well under these rules, said Ellen Zuckerman, a senior associate with SWEEP, an independent, non-profit organization that promotes energy efficiency in the Southwest.
