Tucson Electric Power (TEP) is embarking on a groundbreaking initiative to reinforce Arizona's energy landscape by constructing a massive battery energy storage system known as Roadrunner Reserve. Anticipated to be one of the largest in the state, this 200-megawatt (MW) system will have the capacity to store an impressive 800 megawatt hours of energy. When operating at full capacity, it can provide energy for approximately 42,000 homes for four hours. Roadrunner Reserve is scheduled to commence operation in the summer of 2025.

TEP's vision for Roadrunner Reserve is to charge the grid-connected battery during the morning and early afternoon, aligning with peak solar productivity. Later in the day, when energy demand typically surges, the stored energy will be released to meet customers' needs. Strategically, the system will be situated adjacent to a TEP substation in southeast Tucson.

Susan Gray, TEP's President and CEO, emphasized the significance of Roadrunner Reserve in the context of TEP's renewable energy ambitions. "This new system will be particularly important in helping us satisfy peak energy needs during the summer," she stated. Battery energy storage systems, like Roadrunner Reserve, play a pivotal role in optimizing the use of renewable energy resources by effectively managing energy output.

TEP's commitment to sustainability is evident in its 2020 Integrated Resource Plan (IRP), which outlines the path to reducing carbon emissions by 80% and adding up to 1,400 MW of energy storage by 2035. With this ambitious endeavor, TEP takes a significant step forward in its mission to provide cleaner, more reliable energy to the region.

As part of TEP's journey towards sustainable energy, Roadrunner Reserve joins the ranks of recent renewable energy additions, including the Oso Grande Wind Project, the Wilmot Energy Center, the Borderlands Wind Project, and the Raptor Ridge solar system. These initiatives collectively reinforce TEP's commitment to cleaner, more efficient energy production and delivery.
