Our renewable resources

UniSource Energy Services is expanding its portfolio of clean renewable resources to help provide safe, reliable and affordable electric service to our communities.

UES’ renewable resources produced more than 100,000 megawatt hours (MWh) in 2015. That’s more than 6 percent of TEP’s total 2015 retail sales, surpassing Arizona’s Renewable Energy Standard requirement of 5 percent for the year. 

UES will continue to invest in innovative, cost-effective renewable programs that offer benefits for all customers.

Supporting solar for everyone

The Bright Arizona Community Solar Program allows residential and business customers to cover some or all of their electrical needs by purchasing locally generated solar power.

Donations to UES’s Voluntary Solar Contribution Program help fund the installation of rooftop solar systems at homes built by Arizona chapters of Habitat for Humanity.

Considering solar for your home or business? Here are important questions to consider. Or, learn more about connecting to UES’ local distribution system. 

Solar

UES Owned (Utility Scale)

Rio Rico
Built on 37 acres near Interstate 19, this 5-megawatt photovoltaic system provides enough power to supply about 1,500 homes for a year.

La Senita
This 1.2-megawatt photovoltaic system includes more than 5,000 solar panels installed on six acres leased from the Kingman Unified School District. An adjacent learning center was designed to help students explore renewable energy science and technology.

Power Purchase (Utility Scale)

Red Horse Expansion
UES more than doubled its renewable generating capacity with the expansion of the Red Horse solar and wind project near Willcox, Ariz. The 37-megawatt expansion produces enough electricity annually to power more than 7,500 homes. The facility is UES' single largest renewable energy resource.

Kingman Wind Farm (solar)
A 500-kilowatt, polycrystalline silicon photovoltaic array makes up the solar half of Arizona’s first utility-scale system to combine and produce energy from wind and sunshine. The Kingman Wind Farm, developed by Western Wind Energy, provides UES with enough generating capacity to power about 2,200 homes for a year.

Black Mountain Solar
Designed and built by Solon, this 10-megawatt, single-axis tracking solar project is installed on about 60 acres near Kingman. It uses more than 40,000 solar modules to produce power that is sold to UES through a 20-year purchase power agreement.

Wind

Kingman Wind Farm
Five 2-megawatt Gamesa wind turbines are used to produce power at the Kingman Wind Farm, Arizona’s first utility-scale system to combine and produce energy from wind and sunshine. The Kingman Wind Farm, developed by Western Wind Energy, provides UES with enough generating capacity to power about 2,200 homes for a year.

Solar resource capacity

Our community scale solar resources have a combined capacity of 66 megawatts. That’s enough clean, green energy to power more than 14,000 homes for a year.

Red Horse Expansion More Than Doubles Solar Capacity

The 37-megawatt expansion was completed in July 2016. It will produce about 66,000 megawatt hours of electricity annually.
