Wrapping up the series with a forward look at the trends that will shape Texas electricity costs for the rest of the decade.
Over the past nine weeks, we’ve worked through the structural realities of the ERCOT market: how prices are set, why summer 2026 looks the way it does, what Senate Bill 6 actually changes, how renewables and batteries are reshaping the resource mix, and what every Texas business should be doing right now to manage cost and risk. This final installment looks ahead.
Predictions about energy markets are humbling. The honest version is that nobody knows exactly how the next five years play out — there are too many moving parts, from regulatory decisions to weather to fuel prices to whether the data center build-out fully materializes. But the broad direction is reasonably clear, and Texas businesses that align their decisions with that direction will be in much better shape than those that don’t.
Five Trends to Plan Around
1. Wholesale prices are likely to drift higher.
The forward curves are pricing in tighter conditions, and the underlying drivers — load growth, the cost of building new generation, the expansion of transmission, higher ancillary service procurement — are all pointing the same direction. Year-over-year increases in delivered electricity costs of several percent should be assumed as a baseline, with the possibility of larger jumps in years with significant grid events.
2. Volatility is here to stay.
The same factors that pull average prices higher also widen the distribution. Expect more frequent five-minute price spikes during tight intervals, more frequent grid alerts and conservative operations notices, and more attention to the few critical hours per year when system stress concentrates. Customers on the wrong side of that volatility — index contracts without hedges, fixed-rate contracts that don’t actually fix everything — will pay the most.
3. The data center wave will reshape regional pricing.
Where the new load lands matters as much as how much of it lands. Regions with concentrated data center development will see different transmission cost dynamics, different congestion patterns, and potentially different LMPs than regions without. Locational price differences across the ERCOT footprint will likely widen, not narrow.
4. Battery storage will keep changing the shape of the day.
Storage will continue to compress the difference between midday and evening prices as more capacity comes online. That has implications for time-of-use strategies, for how renewable PPAs are structured, and for how demand response programs are valued. The arbitrage that makes batteries profitable today may compress as the storage fleet grows — but the operational benefit to grid reliability will continue to be significant.
5. Regulatory change will continue at pace.
SB 6 was not the last word. Future legislative sessions are likely to keep refining the rules around large loads, transmission cost allocation, reliability standards, and market design. Businesses that stay close to the regulatory conversation — or work with brokers and advisors who do — will be better positioned than those reacting to changes after the fact.
What to Do Now
If there’s one practical message from the entire ten-week series, it’s this: the era of treating electricity as a passive utility cost in Texas is over. The market is too dynamic, the stakes are too high, and the difference between an informed contract and an uninformed one is too large.
Three actions worth taking in the next 90 days:
- Audit your current contract. Pull the document. Read the pricing structure. Identify every line item that floats, every pass-through, every adjustment mechanism. If there’s anything you don’t understand, get it explained.
- Map your load profile. When does your facility consume the most? Where does it overlap with system peak hours? What flexibility do you actually have? You can’t make smart contracting decisions without this data.
- Plan your next renewal early. If your contract expires in the next 18 months, start the renewal conversation now, not 60 days before expiration. Forward markets reward customers who shop ahead of time.
Closing Thoughts
ERCOT is going through the most significant transformation in its history. The grid that emerges five years from now will look different from the one we have today: more renewables, more storage, dramatically more load, more transmission, and a more sophisticated regulatory framework around all of it.
For Texas businesses, that creates both risk and opportunity. The risk is being caught flat-footed by changes that were entirely foreseeable. The opportunity is positioning your business — through smart contracting, operational flexibility, and informed engagement with the market — to come out the other side paying less than your competitors and operating with more certainty than they have.
Thanks for following along over these ten weeks. The conversation about Texas electricity is one of the most consequential ones happening in the state right now, and we appreciate the chance to be part of it for your business.
The best electricity contract in Texas is not the cheapest one. It’s the one that fits your business, hedges the right risks, and gives you operational room to move as the market changes. Everything else is detail.
