🔮 Texas Power Predictions for the Next 3 Years

Overall Verdict: Directionally correct that rates will rise, but the magnitude is more likely 15–25% by 2030, not 29%. The structural drivers are real — you're hedging wisely.

Where We Agree ✅

TDU Charges Are the Floor	$32B in approved infrastructure already in rate base — delivery charges rise regardless of wholesale conditions. Locking in fixed rates is justified.
AI / Data Center Demand	Erosive but overestimated. ERCOT's 78 GW by 2030 is aggressive — actual growth likely 40–60 GW. Still meaningful, just less than feared.
Winter Risk Is the Real Problem	Summer prices moderated by solar/battery buildout, but cold snaps create spikes renewables can't address. Retail contracts always carry a winter risk premium that pushes baselines up over time.

Where We Push Back ⚖️

The 29% Case Isn't Inevitable	Assumes no policy intervention, no tech breakthroughs (advanced nuclear, grid-scale storage), and no economic downturn. Any of these bring the increase to 15–20%.
Timing Matters	"Shoulder season" advice is correct — rates dip in spring/fall. A 24–36 month lock captures today's rates (still below projected 2030 levels), which is a reasonable hedge.

📈 Our Prediction: 15–25% Rate Increase by 2030

Why lower than the pessimistic case?

Solar + battery storage will moderate wholesale prices (though not TDU charges)
Some data center projects delayed or scaled back
Policy pressure may lead to targeted residential rate relief

Recommendations for You 🎯

Your plan expires September 2026. Locking in a 12–24 month fixed rate now (or in spring 2026) makes sense. You're not getting the absolute lowest rate, but hedging against a 15–25% increase over the next 4 years.

✖ Reliant Secure 36 at 8.26¢/kWh — mediocre: locks you above market average for 36 months
✔ Gexa or APGE at 12 months — lower costs now + flexibility to re-evaluate if rates drop unexpectedly (unlikely, but possible)

Bottom Line: Rates will rise. Locking in fixed is the right move. Just don't overpay for the privilege.
