Renewable energy information

UES is committed to promoting the use of renewable energy by residential and commercial customers.

Under the state's Renewable Energy Standard and Tariff (REST), approved in 2008 by the Arizona Corporation Commission (ACC), UES and other electric utilities in Arizona are required to supply increasing amounts of renewable energy, with a target of 15 percent of total power sales by 2025.
