How PJM’s shortfall capacity makes your real estate more valuable

The PJM capacity crunch created a scarcity premium for distributed storage. It's real, it's paying now, and it has an expiration date.

If you own or occupy commercial property, you've seen demand charges keep climbing. Your utility is sending reserve margin warnings. Battery storage right now isn't a sustainability decision, it's a capacity market position, and the market is paying an unusual premium to anyone who can take one.

What is a shortfall and why does it matter to real estate?

In July, PJM's Base Residual Auction for the 2028/2029 delivery year cleared at the FERC-approved price cap for the third consecutive time and came up 6,831 MW short of the reliability requirement. The reserve margin landed short (14.7%) against the target (20%). New supply barely showed up with a 32% decrease from the auction before. In short, this means the capacity supply is not meeting consumer demand.

Then, on September 30, PJM was supposed to open offers in a one-time emergency auction to address the shortfall. It never happened, because federal regulators sent the plan back the day before over disagreements about who should foot the bill, and PJM shelved the auction for the next 5 months.

You don't need to care about grid economics to care about what happens next. If you're a property owner or an occupier in a capacity-constrained zone, the consequences show up as line items and operational headaches:

• Cost creep. Capacity costs flow through to retail rates and demand charges. Three straight auctions at the cap means three straight years of upward pressure baked into your bills.
• Reliability risk. A 14.7% reserve margin means PJM operates with slimmer margins and more exposure during extreme weather.
• Operational friction. Curtailment programs, large load registries, and emergency load management procedures are all being written right now. The rules governing when your site gets asked to cut load are being drafted whether or not you're at the table.
• Deferred decisions get more expensive. Every quarter you wait, more supply comes online and the premium you could have captured shrinks.

You're not just a ratepayer. You're a grid asset.

In a capacity-short market, and no clear timeline for additional capacity, a commercial site with usable ground or parking area becomes an opportunity. It's one of the few places where capacity can physically be built with battery energy storage systems (BESS) more quickly and close to where the demand actually is.

That distinction has real money attached to it. How you get paid for that depends on which side of your meter the battery lives on.

Behind the meter, the battery works for your building. It lowers electricity rates, provides backup power when the grid goes down, and can still earn revenue from grid programs. One note on the backup: nobody is promising eight hours of full-building power, and you shouldn't pay for it. What an hour of lights, point-of-sale, and controls buys is a controlled shutdown instead of a scramble, which is worth more than it sounds to anyone who has managed an unplanned outage.

Front of the meter, you're leasing land to the grid. The battery connects to the utility system rather than your building, so your operations aren't involved at all. You provide suitable, interconnectable property and receive a long-term ground lease: contractual income against square footage that wasn't earning, with no capital outlay, and no operating exposure.

Which one fits depends on your site more than your preference. Available land, the serving circuit, your load profile, and your lease structure all push toward one or the other, and a property that doesn't pencil for one often pencils for the other.

Power is already sitting on commercial property

PJM needs 6.831 GW. Across our PJM footprint, we've identified roughly 17 GW of distributed capacity potential across 8,700 commercial and industrial sites.

As we've written about what it takes to qualify a site for storage, a parcel being big enough isn’t enough to determine whether a site can host a battery. Most sites don’t qualify when running it across a portfolio, but the sites that qualify are worth money.

Capacity value concentrates where the grid is most constrained, which is why the eastern zones command a premium that transmission constraints are expected to hold in place. This is a portfolio problem before it's a site problem, and it should be run as one.

There's a second-order effect worth naming. Thirty-two gigawatts of distributed batteries across commercial properties is a genuinely different answer than a handful of new gas plants sited in somebody's neighborhood. Same reliability outcome, distributed across existing developed land, with the value flowing to property owners and local tax bases instead of into a single large asset. That's not a talking point. It's a materially better way to close a capacity gap, and it's the version of the buildout that communities actually consent to. Distributed resources have already proven this at scale in California.

The solution is delayed. The premium isn't.

The emergency auction is sitting in a regulatory process for the next several months.

Buyers, such as hyperscalers and large manufacturers, who need capacity aren't going to wait that out. The resources they can contract with right now are the ones that don't depend on a new federal mechanism being approved first, and distributed storage on commercial property sits squarely in that category. PJM's recent rulemaking has been moving in its favor on several fronts.

The cost side, meanwhile, keeps moving toward you. The disagreement holding up the auction is fundamentally about cost allocation, and regulators have signaled those costs should be assigned to suppliers in the zones where demand is growing fastest. Suppliers recover costs the way they always have, through the rates they charge.

So the window isn't what most people assume. This isn't a race against a wave of new supply about to arrive and compress prices. It's a race against the other property owners getting their sites qualified and contracted during a pause nobody can put an end date on.

The next step for C&I real estate

Every quarter of deliberation costs your position in a queue that's forming right now. You don't need a strategy memo on storage. You need to know which of your properties qualify and what they're worth, so the conversation moves from whether this makes sense in theory to which buildings to start with. Qualify your sites and find out what you're sitting on.
