Tucson Electric Power is on a journey to achieve net zero carbon emissions by 2050 — and we’re committed to keeping energy affordable and reliable every step of the way. But we can’t do it alone. We need our customers, partners, and community to help us get there.
By taking simple steps to save energy and shift usage to times when more wind and solar power are available, you can make a real impact. In addition to reducing your energy bills, these actions also help us:
- Reduce the need for new energy resources
- Protect our environment
- Reduce our community’s carbon footprint
To celebrate those leading the way, we recognize local businesses, nonprofits, and organizations that champion sustainability, embrace innovation, and make thoughtful choices about their energy use.
Meet our 2025 Net Zero Heroes:

These inspiring organizations were nominated by TEP employees and community members for their outstanding efforts to build a brighter, cleaner future.
What Is TEP Doing to Achieve Net Zero?
We’re expanding our clean energy resources and cutting carbon dioxide emissions. Since 2019, we’ve reduced annual CO₂ emissions from our generating resources by 38% — thanks to retiring coal-fired plants and adding new wind and solar systems.
We’re also investing in energy storage to make renewable power more reliable. Our largest battery system, Roadrunner Reserve, came online this summer. The system’s four hour, 200-megawatt (MW) capacity will be doubled with an expansion that’s coming online in early 2026.
Next up: Wilmot Energy Center II, featuring a 100 MW solar array and a 100 MW, four-hour lithium-ion battery system, which is expected to come online in 2027. The existing Wilmot Energy Center includes 100 MW of solar generation and 30 MW of two-hour storage.
Meanwhile, Winchester Solar, located in Cochise County, will include an 80-MW solar and 80-MW battery energy storage system. The system is expected to come online in 2027.
