How a Self-Storage Company Turned 60 Rooftops Into a 44-Megawatt Income Stream
By Keith Reynolds | Publisher & Editor, ChargedUp!
The short version: Public Storage is hosting 60 rooftop community solar projects, developed and operated by Solar Landscape across ComEd's northern Illinois grid, that will add 44 megawatts of capacity and serve about 6,150 households, with 10 sites already generating power. The self-storage company supplies the roofs; a third-party developer supplies the capital, engineering, and operation. For an owner with large flat rooftops, the arrangement shows a way to earn recurring income from unused roof space without spending a dollar of capital or taking on the risk of running an energy system.
Key Facts at a Glance
Public Storage will host 60 rooftop community solar projects with developer Solar Landscape across northern Illinois, announced July 31, 2026.
The portfolio adds 44 megawatts of capacity and is expected to serve about 6,150 households, with 10 sites already energized.
The projects are expected to deliver an estimated $750,000 in annual electricity bill savings for subscribers.
The model needs no upfront capital from the property owner; the developer builds, owns, and operates the systems.
Public Storage expects to expand its overall solar program to 1,300 of its properties by the end of 2026.
What Exactly Did Public Storage and Solar Landscape Announce?
On July 31, 2026, the utility ComEd joined Solar Landscape and Public Storage to announce plans to develop 60 rooftop community solar projects across northern Illinois over the next two years, with 10 sites already generating power, according to the companies' announcement. Together the projects will deliver 44 megawatts of community solar, one of the largest community solar deployments in Illinois. Community solar is a shared arrangement that lets multiple households and businesses subscribe to a single solar installation and receive credits on their utility bills, without putting panels on their own roofs.
The economics are concrete. Once complete, the projects are expected to generate enough electricity each year to power roughly 6,150 households while delivering an estimated $750,000 in annual electricity bill savings for subscribers, per the announcement. Public Storage, a member of the S&P 500 that operates thousands of self-storage facilities, is contributing what it has in abundance: large, flat, unobstructed rooftops across suburban northern Illinois. Solar Landscape develops and operates the systems, and ComEd handles grid interconnection and the subscription framework.
Why Does the Ownership Structure Matter to an Owner?
The most instructive part of this deal is who does what. The property owner does not buy, build, or run the solar systems. It leases its roof space to a developer that supplies the capital, the engineering, the construction, and the long-term operation and maintenance. The owner collects a recurring payment for the roof, and the energy risk sits with the party equipped to manage it. This structure removes the two obstacles that most often stop a commercial owner from putting solar on a roof: the upfront cost and the burden of operating an unfamiliar system.
For an owner, that turns a rooftop from a maintenance liability into an income-producing asset. A warehouse, a distribution center, or a big-box retail roof is usually dead space, valued only for keeping weather out and occasionally for mechanical equipment. Under an arrangement like this one, that same roof produces a lease payment on top of its existing function, with no capital outlay and no operational duty. The income is durable, tied to a long-term agreement, and it improves the property's net operating income, the figure on which the building's value ultimately rests, without the owner deploying capital that could go elsewhere.
Why Is This Happening in Illinois Now?
The deal sits inside a supportive policy and grid context. ComEd operates one of the largest community solar programs in the country and expects to have some 400 community solar installations across its northern Illinois territory by the end of 2026, according to ComEd. The utility's chief executive framed community solar as a way to help close the gap between rising power demand and available supply while lowering customer bills. More than 1.8 gigawatts of distributed energy resources have already connected in Illinois, making it a leading Midwest state for that capacity.
The timing reflects a broader shift. With electricity demand climbing and new large-scale power slow to connect, utilities and developers are turning to commercial rooftops as a fast, already-developed platform for adding capacity. A rooftop project sits on land that is already built, near existing load, and it can be aggregated across many small and midsize sites into a meaningful distributed resource. For the host owner, that growing demand for roof space is what creates the lease income. The same grid stress this publication tracks each week is, from the owner's side of the table, a rising bid for an asset they already own.
What Should an Owner With Large Rooftops Do?
The practical lesson is to treat roof space as a potential revenue asset, not just a building component. An owner with substantial flat roof area, particularly in a state with an active community solar program, has something developers now compete for. The first step is a feasibility question that mirrors the diligence any capital decision deserves: roof condition and remaining useful life, load-bearing capacity, the utility's community solar rules, and the interconnection outlook for the local circuit. A roof nearing replacement or lacking structural headroom may not qualify, while a sound roof in the right territory may command a genuine lease.
The structure also carries obligations worth understanding before signing. A rooftop energy agreement can affect roof warranties, insurance, future repairs, access rights, and diligence in a sale or refinancing, so it belongs in the same review discipline as a lease or an easement. Handled well, it converts unused square footage into durable income with no capital at risk. Public Storage's 60-rooftop portfolio is a template any owner of large commercial roofs can study: the roof is no longer just an overhead surface in the building file. In the right program, with the right partner, it becomes part of the local power system and a line on the income statement.
