Our renewable resources
Tucson Electric Power has a continually expanding portfolio of clean renewable resources to help provide safe, reliable and affordable electric service to our community.
TEP’s renewable resources produced nearly 700,000 megawatt hours (MWh) in 2015. That’s nearly 8 percent of TEP’s total 2015 retail sales, surpassing Arizona’s Renewable Energy Standard requirement of 5 percent for the year.
Investment in clean, green generating resources and renewable programs will continue as TEP reduces its reliance on coal. The company anticipates adding 800 megawatts (MW) of new renewable capacity by the end of 2030, boosting its total renewable energy portfolio to approximately 1,200 MW.
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
Hundreds of customers have signed up for the new, innovative TEP Residential Solar Program, which provides fixed-price electric service for up to 25 years using solar arrays installed on customers’ homes. Find out if Residential Solar is right for you.
The Bright Tucson Community Solar Program allows residential and business customers to cover some or all of their electrical needs by purchasing locally generated solar power.
Contributions to TEP’s Voluntary Solar Contribution Program help fund the installation of rooftop solar systems at homes built by Arizona chapters of Habitat for Humanity.
TEP is seeking regulatory approval of a new program that would provide fixed-rate benefits for 10 years to customers who agree to purchase the output of local, community-scale solar arrays.
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. As part of its most recent Renewable Energy Standard and Tariff (REST) Implementation Plan, the company has entered into long-term agreements for the construction of two large energy storage systems that will help improve service reliability and study how such systems can 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.
