TEP and APS Submit 2026 Plans, Still Rely on Fossil Fuels
WHY IT MATTERS
The ongoing fossil‑fuel investment means higher operating costs and slower progress toward Arizona’s climate targets, affecting consumers and the state’s emissions trajectory.
What happened
On Friday, Tucson Electric Power and Arizona Public Service filed their 2026 Integrated Resource Plans, outlining how the utilities will meet demand over the next fifteen years. Both plans feature additions of renewable generation and battery storage, yet they also earmark significant budgets for fossil‑fuel power.
The documents reveal that, despite the push toward clean energy, the utilities will continue to invest in coal, natural gas, or other fossil sources to secure reliability and meet regulatory targets. The plans do not detail the exact mix, but the continued fossil‑fuel spend signals that Arizona’s electric grid will not fully transition away from carbon‑intensive sources in the near term.
The inclusion of renewables and storage is a step forward, yet the persistent fossil‑fuel allocation underscores the challenges of balancing cost, reliability, and climate goals.
