BESS Platforms are for Sale

Originally Written July 18, 2026

Scroll through any infrastructure banker’s inbox right now and a pattern jumps out: battery energy storage (BESS) development platforms are for sale. Not one or two. A smorgasbord.

It’s worth asking why, because the answer says a lot about where this market actually is versus where it was supposed to be.

Built for a future that hasn’t arrived yet

Many BESS developers were built on a bold thesis: develop 5 to 10 gigawatts over five years. The ambition was right. But a lot of these platforms staffed up and stood up full development machines before they had a single operating project to show for it, and operating projects can be a year or more away.

To bridge the gap, some bought an operating asset out of the gate, usually in ERCOT. For the most part, those assets have underperformed their pro formas. Many ERCOT projects carry tolls priced well below other markets: some fixed, some structured to retain merchant upside. That second group was, in effect, a bet on price spikes big enough to rescue the model. Those spikes largely haven’t come.

So, why the wave of sale processes?

Three reasons, mostly.

First, and most common: they’ve run out of runway. Equity is gone, and in some cases the credit lines are tapped too. Without fresh capital, you can’t build the next asset or fund the next stage of development. So you sell.

Second, a healthier reason: some developers have quietly assembled a large platform and a genuine pipeline, and they’ve decided this is a sensible moment to bring it to market.

Third, the repeat sellers: several distressed developers are back for a second or third trip through a process.

It’s not all bad news

Here’s the part the doom-scrollers miss: a few of these platforms are getting real attention and real bids.

The buyer universe is genuinely there. Strategics own relatively few of these platforms today, and select private equity and infrastructure funds are hunting. Infra funds in particular have a structural reason to engage: most can’t fund pure development, so a platform that pairs a pipeline with some operating assets fills a gap in their mandate. There are also persistent rumors of foreign buyers, mainly out of Asia, still looking for a way into the US market. 

Demand for capital, in other words, isn’t the problem. Quality is. 

The uncomfortable question: are any of them profitable?

For most of these platforms, it’s genuinely unclear whether they’re profitable, or will be, as they keep legging into new assets. That’s the honest tension every buyer has to sit with.

XIP has valued several of these platforms. Our view: in today’s market, platforms don’t carry “platform value” in the abstract. And yet buyers are still willing to pay a premium for some of them — for momentum, for a team, for synergies, and most often for a pipeline of already-contracted projects. Sometimes that premium is justified. Sometimes it isn’t.

How buyers should actually underwrite these

XIP prefers a combined bottoms-up and top-down analysis. The most useful version is
disarmingly simple:

1. What are you paying for the platform?
2. What capex and opex do you have to put in from here?
3. Given those two, what EBITDA and net cash flow do you actually get?

Then apply the test that matters: if you can’t see at least a 2x on your capital over five years, assuming everything goes to plan (which it never does) and assuming a proper exit multiple, you have to ask whether you’re willing to take that risk and overpay. Some buyers are. That’s a call to make with eyes open, not by accident. For some strategics, it’s more about having the arrow in your quiver, while having the ability to amortize the investment over time and across a very large portfolio of assets.

If this feels familiar, it should. It rhymes with the wave of solar platforms that traded a cycle ago, and it isn’t hard to look back and see which of those bets paid off and which didn’t.

And about the data center thesis…

Plenty of buyers are underwriting these platforms on the assumption that data center growth will pull through enormous new BESS demand. It might. But that trade is already crowded, and enthusiasm isn’t execution. The questions to press are the unglamorous ones: Has the team built BESS before? Have they interconnected them? What was their historical uptime? A pipeline is a promise. Delivery is a track record.

The bottom line

This is a market with real opportunity and real traps, often sitting inside the same data room. The winners won’t be the buyers who move fastest or pay the most. They’ll be the ones who
underwrite honestly and know exactly what they’re paying for.

That’s the work XIP does. XIP has valued these platforms – and one of our Managing Partners has built one (sPower) – and knows what separates a premium worth paying from a premium
you’ll regret, and is glad to pressure-test any BESS platform — as a buyer, a seller, or a lender — before the number gets committed.
