5 Takeaways From EMC25 Houston Every Texas Commercial Energy Buyer Should Know

The 25th Annual Energy Marketing Conference (EMC25) wrapped up in Houston on April 21, 2026. Two days of panels and keynotes from brokers, REPs, and platform vendors, all centered on a single theme: the Texas market is changing fast, and the rules are still being written.

If you run a business in Texas and pay an electricity bill every month, you don't need to read every panel deck. But there are a handful of shifts coming out of EMC25 that will absolutely show up in your invoices, your contracts, and your renewal conversations over the next 12 to 24 months. The way Texas deregulated electricity works for businesses is the same baseline, but the line items on top of that baseline are about to evolve.

Here are the five takeaways that matter most.

1. SB6 is the biggest market design change in years, and commercial buyers will feel it

Texas Senate Bill 6 (SB6) was the dominant topic at EMC25. The short version: ERCOT is dealing with an unprecedented surge of large load requests, mostly from data centers and AI infrastructure, and SB6 is the framework being built to manage it.

The panel on SB6 and ERCOT interconnection reforms made a few things very clear:

• The interconnection queue is overloaded. What used to be a six-week study can now stretch 18 months or more. ERCOT is moving to a "batch zero" process to triage the queue, with biannual batch studies after that.
• Large loads will face new fees and stricter timelines. Proposed entry and study fees, partial capacity allocations, and tighter project schedules are all on the table.
• The 4CP cost allocation rule is under review. With solar adding gigawatts of capacity, system reliability is shifting away from the classic 3 PM summer peak toward evening net-load hours. A monthly CP construct (similar to California) is being seriously discussed.

"Uncertainty is always negative. It always creates risk and always makes prices go up. I don't want to risk my business and I don't know what's going to happen. In the long term, what we've seen through all the other regulatory moves is that everyone else would like to do the same thing as Virginia. It is likely that others will follow suit."

Sherry Fuller, Vice President of Customer Management, BP Energy Retail Company, ERCOT SB6 / Interconnection Reforms panel

What it means for commercial buyers: SB6 isn't just a data center story. The way capacity costs are allocated, the way reliability is priced, and the way demand response is structured will all evolve. Expect new line items on commercial invoices, and expect contract language to start handling regulatory change more explicitly.

2. Your bill is mostly non-energy charges, and that's only going to grow

One of the most useful clarifications from EMC25 was around why power prices keep rising even when natural gas is cheap.

The answer: the energy component (the actual fuel cost) is only one piece of a commercial electricity rate. The non-energy components, capacity obligations, ancillary services, transmission and distribution charges, and renewable portfolio standard adders, often drive more of the total cost than the commodity itself.

With SB6 introducing new ancillary products (think multi-hour ECRS-style services with battery eligibility), and with 4CP under review, those non-energy buckets are about to get more complicated, not less.

"The grid is changing with the growth in solar. It's the net load hours at sunset that really matter, not 3:00 p.m. You have enough solar on the system, but for reliability, do you have enough in the evening hours? And they're talking about going to a once-a-month, like 12CP or whatever they are now. California went to that."

Keith Poli, Principal in Commodities Management, Constellation Energy, ERCOT SB6 / Interconnection Reforms panel

What it means for commercial buyers: When you compare quotes, ask suppliers and brokers to break out the energy component from the pass-through and capacity-related components. Two contracts at the same headline rate can have very different risk profiles depending on how regulatory pass-throughs are written. The five-component rate framework is the simplest way to keep them honest.

3. Reliability has surpassed affordability as the top C&I concern

This one stood out across multiple panels. For large commercial and industrial customers, the conversation is no longer "how do I get the cheapest rate?" It's "how do I make sure I have power when I need it?"

A few drivers behind that shift:

• Renewables intermittency means more volatile pricing and more frequent thin-margin reliability events.
• Data center load growth is competing with traditional commercial and industrial demand for limited grid capacity.
• Memory of Winter Storm Uri (February 2021) is still very much shaping risk management at every level.

Panelists from the major suppliers were direct about this. Reliability and uptime now drive procurement decisions for the largest accounts, with affordability as a close second.

As David Bisno, Chief Commercial Officer at Shell Energy Solutions, made the point on the Retail Energy, AI, and Market Dynamics panel: for large C&I customers, reliability has surpassed affordability as the top concern, and unmanaged scale destroys value in a market that still has room for retailers of every size. Frank McGovern of ClearView Energy, on the same panel, framed the new normal this way:

"Hundred-year disruptive events are becoming more frequent, requiring businesses to be nimble, prepared, and diversified."

What it means for commercial buyers: If your business can't tolerate an outage, your procurement strategy needs to include more than just price. Ask your supplier about their hedging discipline, their financial strength, and how they communicated with customers during the last few extreme weather events. The post-Uri risk management reforms (lower price caps, eliminated unsecured credit, stress-testing frameworks) are working, but only with suppliers that take them seriously.

4. Demand response and flexible load are the next big commercial product

A recurring theme: ERCOT's preferred answer for managing large new loads is optimization, not blunt curtailment. That opens up real opportunities for commercial customers who can shift load.

A few specifics from the panels:

• New demand response programs are being designed for loads greater than 75 megawatts, and a residential DR product is also in motion.
• Only about 3% of the roughly 85 GW of dispatchable capacity in ERCOT actively curtails for 4CP today. Panelists agreed there's room for that to grow significantly.
• Texas has a $10 billion Texas Energy Fund earmarked for new generation, and recent capacity additions have been dominated by batteries and solar.

"It's probably fair to say it's early days. One thing it's missing is, it talks about it as if it's controlled rather than optimized. So if you're looking at such large loads, why would you not optimize them rather than just curtail?"

Jay Zivicker, Head of Business Development, Kenergy, ERCOT SB6 / Interconnection Reforms panel

What it means for commercial buyers: If your operation has any flexibility in when you run, talk to your REP or broker about DR participation. Programs are evolving fast, and the economics are starting to favor customers who can be a partner to the grid rather than just a consumer of it. At the same time, ask hard questions about curtailment hours, opt-out rules, and operational impact before you sign anything.

5. The retail energy market is consolidating, but smaller and mid-sized REPs are getting more nimble

One of the most interesting panels of the conference was the broker-supplier dynamic and the role of technology in retail energy. A few patterns came through clearly:

• Consolidation is accelerating on both the supplier and the broker side.
• Smaller and mid-sized REPs are leaning into technology (mobile apps, modern CRMs, AI-driven operations) to outmaneuver larger, slower competitors.
• Customer experience expectations are no longer set by other utilities. They're set by Amazon, by mobile banking, by every other digital service your team uses.

On the Retail Energy, AI, and Market Dynamics panel, Brian Hines (formerly of Vistra Energy) put hard numbers on the digital shift, citing app-based service usage at Vistra jumping from 17% to 85%, a clean illustration of how customer expectations have moved from "utility-grade" to "Amazon-grade" in a few short years. Darryl, a smaller retailer on the same panel, framed the consolidation flip side directly: that consolidation actually creates room for nimble, smaller companies to "run circles around" the larger, bureaucratic incumbents.

Neville Raghee, founder of Budget Power, drove the customer side of this point home in his EMC25 keynote with 23 years of retail energy lessons. The verbatim that stuck with me:

"The customer wants four very simple things. One: give me a fair rate. Two, don't shock me when I get my monthly bill. Three, don't screw me at renewal. And four, I'm not going to call you frequently, but when I do, pick up the damn phone."

What it means for commercial buyers: Don't assume bigger is better. Some of the most customer-friendly retailers in Texas right now are mid-sized companies that have invested in technology and stayed disciplined on hedging. Ask about their renewal policy specifically. A supplier that charges existing customers more than new customers from the same channel is telling you exactly how they value your loyalty.

The bigger picture for the Texas commercial electricity market 2026

If I had to sum up EMC25 in one line, it would be this: Texas is figuring out how to absorb the largest demand shock the grid has ever seen, and the rules are being written in real time.

For commercial buyers, that's both a risk and an opportunity. The risk is that contracts signed today on yesterday's assumptions will look very different in two years once SB6 fully rolls out, batch zero settles, and 4CP is restructured. The opportunity is that customers who pay attention, ask the right questions, and partner with suppliers and advisors who actually understand the mechanics will be in a much stronger position than the ones who just shop on headline rate.
