Why October 8th? Because hydrogen's atomic weight is 1.008. 💧

Hydrogen is the simplest element in the universe, but building a hydrogen economy is anything but simple. And one of the biggest factors in whether a project succeeds isn't the technology at all. It's the electricity rate it runs on.

Earlier this year, CES', Gaby, Associate Director -Energy Advisory, partnered with the Hydrogen Alliance on a joint study exploring that question. Using our CoMETS modeling platform, our consulting team simulated a 10 MW PEM electrolyzer paired with 10 MW of solar, testing how it performs under different rate designs, hydrogen prices, and capital costs.

What we found:
➡Flexible operation beat constant, around-the-clock production in every scenario we modeled
➡ Rate design often matters more than capital cost reductions in making a project pencil
➡ Flexible electrolyzers can help utilities too, easing peak demand and making better use of the grid we already have

In other words, electrolyzers aren't just big new loads. With the right policies in place, they can be grid partners.

This work was shaped by conversations with electrolyzer manufacturers, developers, and technical experts across the industry, and we're grateful to everyone who shared their insight. To all the people working to turn hydrogen from promise into practice: happy Hydrogen Day, and thank you.

PJM's regulation market isn't the one batteries were built for anymore.

Most batteries operating in PJM so far have been regulation-only assets, with shorter durations and frequent cycling, all built around one revenue stream. That strategy made sense under the old market design. The design is changing.

In our recent Lunch & Learn, BESS Standalone vs. BESS + Solar in PJM: Which Configuration Wins?, Frierson, Associate Director, Energy Advisory, Consulting - North America, walked through what's reshaping the regulation story:

➡ Phase one (October 2025): PJM replaced the separate Reg A and Reg D signals, along with the 40% cap on Reg D resources, with a single signal. It's faster than the old Reg A but slower than Reg D.
➡ Phase two (coming next): PJM plans to procure regulation up and regulation down separately, which brings it closer to structures like CAISO's.
➡ Short-term effect: Regulation prices have run high this year. The new opportunity cost methodology ties regulation prices more closely to real-time LMP spikes, and precision-only performance scoring is pushing down scores for conventional units that are still adapting to the faster signal.
➡ Long-term effect: Our forecasts show regulation pricing trending down over the coming years, which means regulation alone may no longer be enough to support a storage project.

What makes this analysis valuable is where it comes from. Because a CES business line operates batteries in PJM today, our consultants can test their market hypotheses against what those assets are actually seeing in real-time data.

If you're weighing storage configurations or revisiting a revenue stack in PJM, the full session is worth your lunch hour.

When PJM capacity prices spiked last year, ENGIE faced a cost exposure in the millions of dollars that they had never planned for.

They needed a way to pass those costs through to their customers, and fast. That meant building a new product in their systems and breaking it into four separate components, something they had never done before.

So we got to work together. After months of side-by-side testing and development side by side, the solution went live just days before the new market price took effect.

For Nuila, Director PMO IT at , what stands out most isn't the deadline. It's the people:

" Schmid, MGee, Abraham… several of those front-facing employees of CES have truly made a difference because they collaborate with you, they are working side-by-side with you, and frequently communicating with you at all times."

Diego also talked about something new: CES Connect, our executive client conference. It's a room where industry participants and our clients sit down together to work through new market trends. In his words, it's something he had never seen a service provider do before.

That's the kind of partnership we work to build every day. Thank you, Diego and the ENGIE team, for trusting us with the hard problems. And a big shout-out to Kate, Erica, and Rob, and the whole Team at CES for showing up for our clients every day.

What a week at the CES Connect's Executive Conference.

Bringing our clients together in one room is always a highlight, and hearing feedback like this from Frank, Founder of Clearview Energy, made it even better:

"Great conference. Great information, and the chance to have conversations with the CES Team was what made this worthwhile. I didn't realize the depth of your organization and the amount of knowledge you all have."

Thank you, Frank. That's exactly why we hosted this conference.

The sessions and product updates matter, but the real value happens in the conversations in between. That's when our clients get to meet the analysts, consultants, operators, and technologists behind the work, and see how much expertise stands behind every platform and service we provide.

To everyone who joined us, shared your challenges, and asked the tough questions: thank you. Your input shapes what we build next, and we're already looking forward to seeing you again next year.

ERCOT developers: is your BESS strategy still working, or is it time to rethink it?

The 1-2 hour battery rush hasn’t slowed down, but the returns have — squeezed by a volatile wholesale market and a year of consolidation that’s already thinned the field.

This Thursday, CES’s Ann Yu and Pranao Walekar are putting real ERCOT data behind the questions every developer is asking right now:

• Keep targeting congested sites?
• Pivot to longer-duration BESS?
• Co-locate with renewables?
• Or exit the market altogether?

Using , they’ll show how 2hr, 4hr, and 6hr configurations actually perform across energy arbitrage, Regulation, ECRS, NSRS, and FFR — with a framework you can run on your own sites afterward.

ERCOT’s BESS boom has a problem: too many 1-2 hour projects chasing the same congested nodes, a wholesale market that won’t sit still, and a year of consolidation that’s already thinned the field.

So what’s the right strategy — keep targeting congested sites, pivot to longer-duration storage, co-locate with renewables, or walk away?

We’re answering that question with data, not guesswork. Join CES’s Ann Yu and Pranao Walekar for Lunch & Learn 1: Investment Dynamics of 2hr vs 4hr vs 6hr BESS in ERCOT, Aug 27 at 1:00 PM ET.

Using CoMETS and real ERCOT market data, we’ll show how different BESS configurations perform across:
• Energy arbitrage
• Regulation
• ECRS
• NSRS
• FFR

You’ll leave with a framework for running this analysis on your own sites — inside CoMETS.
