CPS Energy Power Plan Impacts Bills

Power bills in San Antonio are getting shaped less by one surprise policy vote and more by a long buildout that is already underway. That’s the part people miss. CPS Energy has a new long-range framework called Horizon 2050, but the bill impact comes from the older, more concrete Vision 2027 generation plan and the utility’s FY 2026 budget — the stuff that actually funds plants, wires, storage and billing systems. ### What actually changed? The newest formal move was strategic, not a fresh rate hike. CPS Energy’s board approved the Horizon 2050 framework on January 31, 2025, and the utility is still taking public input on it in 2026. That framework sets the long horizon. But the near-term spending that affects bills is already in the FY 2026 budget, which says CPS is continuing its board-approved generation plan and major infrastructure work. ### So why are people connecting this to bills? Because utility bills follow investment. CPS Energy’s FY 2026 budget lays out $982.2 million in nonfuel operations and maintenance spending plus $1.5007 billion in capital investments. That money is going into generation, transmission, local electric and gas systems, and IT upgrades that the utility says will eventually support better billing, but they also create pressure to recover costs from customers over time. ### What is CPS building? Basically, a broader power mix. CPS says its Vision 2027 generation portfolio blends natural gas, solar, wind and storage. The utility says it has already added gas generation, started converting the Spruce 2 coal plant to natural gas, and kept expanding battery storage, wind and solar projects. The approved 2023 portfolio included 280 MW from demand reduction through STEP. ### Why does that matter for reliability? San Antonio is growing fast, and old plants are aging out. CPS’s planning materials say the utility was focused on replacing 2,100 MW of retiring fossil-fuel generation by 2030. An April 2025 generation update also pointed to ERCOT projections showing a potential 6.2% energy supply shortfall by summer — a lights-on story. ### What part of the bill moves month to month? Not just one thing. CPS says residential bills combine base rates, a fuel adjustment and a regulatory adjustment. The fuel adjustment can swing up or down monthly depending on actual fuel and purchased-power costs. The current electric fuel adjustment breakdown shows generated power at 41.7%, renewables at 40.3%, market purchases at 3.7%, STEP at 10.9%, and Winter Storm Uri recovery at 3.4%. ### What are customers paying right now? CPS’s bill page says the projected average cost for residential electric customers in May 2026 is 12.4 cents per kWh, with a current 12-month average of 12.9 cents. The last approved general rate increase was 4.25%, approved in December 2023 and effective February 1, 2024. CPS said that change added about $4.45 a month for the average residential electric-and-gas customer. ### Does this mean another rate increase is locked in? No — but the pressure is obvious. CPS and local coverage have both pointed to growth, new generation needs and infrastructure spending as reasons another rate case could emerge. San Antonio’s city council still has final authority over base-rate changes because CPS is city-owned. So the real story is not “your bill changes tomorrow.” It’s that the utility, and future rate fights will be about who pays for that transition and when. ### Bottom line If your bill changes in the near term, the biggest swing is still fuel costs. But the deeper force is capital spending — CPS Energy is rebuilding how San Antonio gets power, and that almost always shows up on customer bills eventually.
