Why Battery Storage Leases Are Happening Now: The 90% Cost Drop That Changed Everything

If you've been hearing more about battery energy storage leases in northern Illinois over the last few years, there's a specific reason — and it comes down to one number: 90%. That's how much the cost of lithium-ion battery storage has fallen since 2010, according to BloombergNEF. This isn't a projection or a hope. It already happened. And it changed the economics of battery storage from a niche technology into one of the fastest-growing infrastructure categories in the United States.

For landowners in the ComEd service territory, that cost collapse is what created the opportunity on your doorstep. Here's why it matters, why the timing is now, and why the window may be shorter than you think.

What a 90% cost decline actually means

In 2010, the installed cost of utility-scale lithium-ion battery storage was roughly $1,200 per kilowatt-hour (kWh). By 2024, it had fallen to around $115-$130/kWh — and costs continue to drop as manufacturing scales globally. This is not speculative technology. It's proven, deployed, and produced in massive quantities.

This kind of cost curve has only one historical parallel: solar panels. Solar module costs fell over 90% from 2010 to 2020, which triggered a global deployment wave. Battery storage is following the same trajectory, roughly a decade behind — and the deployment wave is now arriving.

The mechanism behind this cost decline is cumulative manufacturing learning, not a single breakthrough invention. Every time global battery production doubles, costs fall by a predictable percentage (the "learning rate"). Battery production has been doubling roughly every 2-3 years, driven by electric vehicles, consumer electronics, and grid storage. Each doubling locks in another cost reduction. This is why analysts are confident costs will continue declining — it's not innovation speculation, it's factory economics.

Why lower costs create lease opportunities

Battery storage projects earn revenue by charging when electricity prices are low (overnight) and discharging when prices are high (peak hours, grid stress events, capacity markets). The project is economically viable when the revenue exceeds the capital and operating costs over the project's life.

At $1,200/kWh in 2010, very few projects could clear that bar. At $120/kWh today, hundreds of projects per year are now economically viable — and that's why developers are racing to sign leases and secure grid interconnections across Illinois and the broader Midwest.

The developer building a project on your land didn't need a government breakthrough or a subsidy bonanza to make the numbers work. They needed battery costs to fall far enough that the project earns a return on investment. That threshold was crossed, and it wasn't crossed yesterday — it crossed gradually over the last five years, which is exactly why you're seeing an accelerating wave of projects in northern Illinois right now.

89 GW of battery storage in the US interconnection queue

The scale of what's happening nationally puts the Illinois opportunity in context. According to Lawrence Berkeley National Laboratory, there is currently 89 gigawatts (GW) of battery storage in the US interconnection queue — projects that have applied to connect to the grid and are working through the approval process.

To put that in perspective: 89 GW is more battery storage than the entire US has built in its history, waiting in line to be connected. Not all of it will be built — some projects will drop out as economics shift or sites become unavailable. But the scale of the pipeline confirms that this is not a speculative trend. Capital has made a decision, and it is betting heavily on battery storage.

In the ComEd zone specifically, the PJM interconnection queue includes over 200 battery and solar-plus-storage projects totaling thousands of megawatts. Developers are fighting for a finite number of viable grid connection points. Properties near substations with available capacity are in demand — now.

Illinois CEJA and the policy layer

Cost declines create economic viability; policy creates market certainty. Illinois's Climate and Equitable Jobs Act (CEJA), signed in 2021, did exactly that. CEJA established procurement requirements for energy storage, updated interconnection rules to streamline the process, and created the policy framework that gives developers confidence to invest in Illinois specifically.

Other states have similar legislation — California, New York, and Massachusetts all passed significant clean energy storage policies. But Illinois's grid structure, land availability, and CEJA provisions make the ComEd service territory one of the most attractive markets in the country for battery developers.

California shows where this is heading

If you want to see what the future of the Illinois grid looks like, look at California today. California has deployed more battery storage than any state — thousands of megawatts on the grid — and the results are clear: battery storage plus solar provides round-the-clock clean power. During evening peak hours when solar output drops, California's battery fleet discharges stored energy and keeps the grid stable.

Illinois utilities are building toward the same model. ComEd needs battery storage to balance the increasing penetration of solar and wind on the grid. This isn't a speculative future need — it's a grid stability requirement that CEJA mandates addressing. The projects being built right now on farmland in northern Illinois are part of that infrastructure buildout.

The time-limited window

Here's the reality that creates urgency: substation capacity is finite and is filling up. Every project that successfully interconnects takes a slice of available capacity at its substation. Once a substation is fully subscribed, new projects face costly upgrades or must look elsewhere.

The properties with the best locations — close to high-capacity substations with significant available interconnection headroom — will be signed first. The window isn't measured in decades. Based on the pace of applications in the PJM queue, the best connection points in northern Illinois could be substantially subscribed within the next 3-5 years.

This doesn't mean landowners should sign anything they're handed. It means the opportunity is real and has a timeline. A landowner who evaluates their property carefully, reviews lease terms with an attorney, and signs a strong agreement in the next year or two will lock in 20-25 years of income on land that was otherwise earning $250-$310 per acre in farm rent.

Battery storage vs the alternatives

Farmers in northern Illinois have been approached about various types of land leases over the years — crop rent, wind turbines, solar farms, cell towers, pipeline easements. Battery storage is different from all of them in one key respect: the combination of very small footprint and very high income per acre.

• Wind turbines pay $4,000-$8,000 per turbine per year — but require 1-3 MW of capacity on 90-180 acres of buffer, and the turbines are a permanent visual feature of your property
• Solar leases pay $800-$1,500 per acre — but take 50-100+ acres entirely out of production for 20+ years
• Cell towers pay $1,200-$2,500 per tower per year — for a single small footprint but with limited income potential
• Pipeline easements pay a one-time fee — but create a permanent encumbrance on your title with no ongoing income

A battery storage lease pays $16,000 to $160,000 per year on 0.2 to 2 acres. The rest of your land stays exactly as it is. That combination is what makes it different — and why developers are willing to offer these terms. The 90% cost decline made the project viable. Your land near the substation made the project possible.

What to do if you own land in northern Illinois

The first step is finding out whether your property is near a substation with available capacity. That's not something you can determine from a map alone — it requires analyzing ComEd substation data, distribution line infrastructure, and the current state of the PJM interconnection queue at specific connection points.
