Green (Energy) Acres
Tucson Electric Power has a continually expanding portfolio of clean renewable resources that help us provide affordable, reliable and sustainable energy service. Our “green acres” of community scale solar arrays and wind farms generate abundant clean energy for our customers.
More than 14 percent of our community's power came from renewable resources in 2018. That's nearly double the 8 percent level required last year by the Arizona Renewable Energy Standard, which calls on utilities to increase their use of renewable energy each year until it reaches 15 percent of retail sales in 2025. The standard is based on the combined output of both utility resources and smaller private systems.
Our investment in clean, green generating resources will continue as we reduce our reliance on coal. TEP anticipates adding 800 megawatts (MW) of new renewable capacity by the end of 2030, boosting our total renewable energy portfolio to approximately 1,200 MW. We're also investing in energy storage, fast-ramping natural gas generators and other facilities needed to support new renewable resources.
TEP, recognized worldwide as an industry leader in renewable energy, will continue to invest in innovative, cost-effective renewable programs that offer benefits for all customers.
Supporting solar for everyone
With panels spreading out far and wide, TEP is working to provide customers with more opportunities to go solar.
The TEP GoSolar Shares program allows residential and business customers to cover some or all of their electrical needs by purchasing locally generated solar power.
Our new TEP GoSolar Home program, available soon, will allow homeowners to get all their power from a local TEP solar array for a fixed price that won’t change for a decade.
TEP also developed hundreds of rooftop solar arrays through its innovative TEP Residential Solar Program, a pilot project that provided fixed-price electric service using solar arrays installed on customers’ homes.
Innovation in solar & other renewable resources
TEP, which built its first large solar array more than a decade ago, understands the importance of innovation in advancing renewable energy. We’re installing innovative energy storage systems to help enhance the resiliency of the local electric gird and support the expansion of solar power resources.
The Solar Zone –a joint venture of TEP, the University of Arizona and solar developers – is the largest multi-technology solar testing, evaluation and demonstration site in the United States. The Solar Zone at the University of Arizona Science and Technology Park in Tucson.
Researchers and scientists in the UA Renewable Energy Network work closely with TEP personnel to test solar panels, forecast weather, experiment with different solar technologies and develop batteries for storing energy.
Affordable, Reliable, Sustainable Solar for Tomorrow
TEP's community-scale solar power systems provide more reliable, affordable and sustainable energy than other renewable energy resources. Their large scale, cost-effective construction helps keep our rates affordable as we increase the sustainability of our energy portfolio. Have a look at the following videos to learn more about our community scale solar resources.
