The power play inside industrial outdoor storage

Industrial outdoor storage has gone institutional for an unglamorous reason: the land is capped, functional and infill, and a scarce functional land product is what allocators rotate toward when they want income without construction risk. IREI's report, centered on Catalyst Investment Partners' co-founders, frames IOS as an increasingly institutional segment of the industrial market drawing demand from a wide range of users on limited dense-location supply—and the most consequential detail in the report is the power behind the yard.

The power matters because of electrified industrial outdoor storage, or EIOS, a sub-segment that remains a small portion of overall IOS demand but is beginning to read as a strategy rather than a curiosity. EIOS is an IOS site that satisfies three conditions at once—industrial outdoor zoning, a dense infill location and excess power capacity—letting the yard serve use cases IOS has not historically served, including passenger electric-vehicle depots, electric-truck charging stations and robotaxi fleets. The definition could broaden over time to include other users that need power infrastructure, up to drone-delivery fleets, which suggests the common thread is the utility connection rather than the vehicle.

Demand today arrives in layers—truck-fleet electrification leads, passenger EVs add a second, and the early autonomous-vehicle rollout contributes a third. The geography is the striking part: until roughly 12 to 18 months ago, electric-truck adoption was effectively a compliance phenomenon in places like California where legislation required it, and now that demand is broadening into other geographies, according to the report. A mandate-driven market needs staging yards in specific counties; an operationally driven market needs them across regions—the latter a far more institutional demand curve.

The underwriting consequence is optionality: a powered, infill IOS yard can compete for fleet leases, charging arrangements and construction-staging agreements out of the same dirt, so the investor is not betting on a single user. That is the feature institutional capital is paying for—a second and third use case without new zoning. The scarcity is not confined to today's occupancy; it lives in the widening set of users a powered infill site can plausibly serve over a long hold.

The data-center economy is pulling the same lever, and this publication has argued before that the trade has moved from power and shells into the supply chain that builds them. The infrastructure contractors, utility companies and equipment-rental firms that build and maintain data centers are natural tenants for outdoor storage. Those adjacent needs, layered on top of EV and autonomous-fleet growth, are pushing demand toward land near urban populations with access to abundant power, and EIOS is where that second wave of data-center demand turns up in the industrial portfolio.

IOS was already a scarce category because infill land with the right zoning is not being created in volume, and adding excess power to the requirement shrinks the eligible pool further. That makes EIOS close to an option on electrification written on a functioning industrial asset: if EV and autonomous fleets scale, the next lease will be signed against the electrical grid, and if adoption curves stall, the owner still holds an IOS yard in a supply-constrained market. The asymmetry explains why a category that is a small share of demand today can command institutional attention before the income statement proves the point.

The practical problem for allocators is that EIOS is not yet scalable as a separate sleeve: demand is emerging from specific fleet operators, utility crews and contractors in specific metros where zoning and power overlap, so the deal flow is granular. That granularity argues for looking inside existing IOS portfolios rather than waiting for a dedicated sleeve. At every property the diligence question is the same—does the yard have excess power capacity, and does its zoning admit the uses that capacity will attract? A yes to both changes the asset's underwriting from industrial storage to infrastructure-adjacent land.

The report does not put a number on the spread between electrified and ordinary IOS, and in most markets a meaningful spread probably does not exist yet. It will appear first where electric-truck mandates and data-center construction overlap, because those are the metros in which fleet operators and infrastructure contractors will bid for the same powered, zoned yards. Watch the lease comparables there; when a fleet depot signs ahead of a conventional storage tenant on a comparable infill site, the market will have priced the scarcity, and the spread should start showing up in the next comps.
