Role and market participation of batteries

Texas just got another winter gut-check—not on the level of the deadly 2021 freeze, but still with enough ice, outages, and anxious headlines to remind everyone how fast confidence can evaporate.

In this episode, Matt Boms and Josh Rhodes unpack what they saw in real time. The biggest takeaways are simple: a lot has improved, and some of the hardest problems are still sitting right in the open.

“There were a lot of questions… what has changed since Winter Storm Uri [in 2021]. The first part of that is absolutely the winterization efforts.”“Texas deserves a lot of credit for how far it’s come since then.”

The first misunderstanding, grid vs. everything else

A chunk of what people experience as grid failure is not the bulk power system at all, but rather the distribution layer: the poles and wires in neighborhoods, tree limbs, cars that skid into poles, and ice that turns ordinary infrastructure into a brittle mess.

That distinction matters:even if ERCOT grid is in decent shape, plenty of Texans could still be in the dark because local equipment gets wrecked.

What actually got better since Uri

The hosts give credit where it is due: far more power plants have been winterized since 2021.At the same time, their conversation keeps circling back to one big concern: natural gas.

Texas leans hard on gas in peak winter conditions, so energy insiders end up asking some version of: Will the gas system hold up when demand spikes and the weather is ugly?

That question is not ideological. It is operational.

The quiet headline: new capacity, new shape

Over the last five years, Texas added a lot of generation, and a big share of it is solar plus batteries. That changes the daily rhythm of how ERCOT meets load.

And it changes the conversation during winter events, too.

Renewables and batteries strengthened the grid last weekend and helped shield Texans from theprice spikes that other regions saw. While batteries do not solve winter, this storm shows how they provide essential electricity when conditions are tight and every megawatt matters.

Josh also gets specific about how people should think about storage—not as a magical substitute for everything else, but as a tool that can provide particular services at particular moments.

The public narrative still lags the reality

Coverage of extreme weather events often flattens into a single question: Did the grid fail?

That framing misses the more interesting, more actionable questions:

* What failed: generation, transmission, distribution, fuel supply, or communications?

* What was close to failing, but did not?

* What investments best reduce the next risk Texas will face?

As the panelists note, there was some tightness and scarcity on the grid last weekend. It was not nothing. But it was nothing like the challenge we faced in 2021.

The next wave is not weather, it is load

Winter events are the stress tests everyone feels, but load growth is the slow-motion pressure that can change everything, including market behavior and planning decisions.

The hosts touch on the reality that even partial progress matters. That is not a victory lap, it is just what real system improvement looks like.

As they note, Texas needs to focus on reliability math, not vibes. What policies move the needle, and what trade-offs Texans are making when we choose between speed, cost, and resilience?

The ERCOT grid is getting stronger. Winterization has helped. The resource mix is changing quickly. Batteries are becoming real operational players. Gas still matters.

But distribution outages still hurt. And load growth is coming, ready or not.
