8 OCTOBER 2026 WorldWide Drilling Resource® Exploring Clean Energy Adapted from Information by Tucson Electric Power Tucson Electric Power (TEP) is starting to take steps to better understand geothermal energy and its potential for providing clean, reliable energy for Arizona. The company is evaluating a wide range of emerging technologies that could complement their expanding portfolio of wind, solar, and energy storage. As energy demand grows, customers, communities, and businesses are looking for around-the-clock clean power. Advanced geothermal energy systems promise clean, always available power; however, the evolving technology requires additional detailed studies and careful evaluation before it can be widely deployed. “Advanced geothermal is one of several clean baseload technologies we’re exploring to understand how it might fit into a future energy mix. This is a developing technology, and our focus right now is on actively engaging with partners to better understand the market, the risks, and where it could make sense over time,” said Sarah Moore, Principal of Emerging Technology & Innovation at TEP. Geothermal systems use heat from beneath the surface to generate electricity. Unlike wind and solar resources which are dependant on weather conditions, geothermal facilities can operate continuously and provide the same reliability as traditional power plants. Interest in geothermal energy has been growing nationwide as utilities and large energy users seek clean power that can be available 24 hours a day. New approaches are expanding the number of locations where geothermal systems can be developed by applying techniques adapted from gas and oil drilling. At the same time, evolving clean energy standards and corporate sustainability goals are increasing interest in reliable resources to meet growing demand. Because geothermal systems can provide consistent output, they are part of broader conversations about how to meet those goals while maintaining reliability. While geothermal systems offer unique advantages, they also pose significant challenges reinforcing the need for a measured, data-driven approach. Exploration can be costly and project timelines can vary. Some advanced geothermal concepts have only recently been demonstrated on a small scale, and others have yet to be proven commercially. TEP is monitoring demonstrations, learning from early projects, and tracking how costs and risks evolve over time, rather than jumping straight into development. “We’re making sure we understand the full range of options that could help us meet future needs for affordability, reliability, and cleaner energy,” Moore said. Part of the preliminary evaluation is reviewing geothermal activity in the Southwest and neighboring states, where geological conditions and existing transmission infrastructure could offer future opportunities. The company is also watching how partnerships between utilities, developers, and large energy users are helping advance early geothermal projects elsewhere. Geothermal exploration is part of the company’s broader strategy to maintain flexibility as the energy landscape continues to change. Moore explained, “We know the future grid will look different than today’s. Our responsibility is to understand what’s coming, evaluate it carefully, and be ready to act when technologies mature and make sense for our customers and communities.” For more information call: (270) 786-3010 or visit us online: www.geothermalsupply.com All New!
