Fleet depot charging subscriptions Market Outlook 2026–2035: Growth Drivers, Key Companies, Strategic Developments & Adoption Forecast — A Meticulous Next™ Foresight Brief

This Meticulous Next™ brief examines charging-as-a-service, where a provider finances, builds and operates charging for a commercial fleet and the fleet pays by subscription, by kilowatt hour or by stall, often with trucks and energy management bundled in. It tests how far charging subscriptions become a standard route for fleet electrification by 2035, and what that means for charging providers, truck makers, fleet operators, energy companies and investors.

Third-party depots are the answer to a power problem. Fleet Forward reported in January 2025 that the Harbor Trucking Association expects 75% of heavy-duty drayage fleets to need third-party charging, that some Los Angeles fleets face waits of up to five years for power upgrades, and that the California Energy Commission estimates a need for about 157,000 medium and heavy-duty chargers by 2030. The conclusion is that fleets which cannot get grid power on their own timetable will buy charging as a service, and the largest demand is where grid access is slowest.

Capital is consolidating the providers. In May 2026 Voltera and Revel announced a definitive agreement to combine their businesses, with EQT as majority owner and Global Infrastructure Partners keeping a minority stake, creating a network of more than 1,000 charging stalls, operating and in development, across 11 major United States metro markets. The conclusion is that infrastructure investors are backing charging operators that build, own and operate depots for fleets and autonomous vehicles, and are paying for scale.

Truck makers are now part of the offer. In September 2026 Forum Mobility began work on four new California depots adding 30 MW, with Tesla running public Megacharging at three of them and contracted offtake and reservations for more than 330 Tesla Semi trucks at its Rancho Dominguez site, and it reports 25 carrier customers with contracted capacity and more than 40 MW of charging online or under construction. The conclusion is that bundles of trucks and charging are being sold as a service, and the supplier of the truck is placing its own chargers inside the depots.

The brief treats fleet depot charging subscriptions as an accelerating signal with a nine year horizon to 2035. It identifies which charging providers, truck makers and fleets move first and what each means for depots, power access and subscription contracts. It is a focused 103-page decision brief that presents an indicative trajectory rather than a segmented market model.

Three third-party models have emerged. Fleet Forward describes infrastructure-as-a-service, where a fleet uses third-party depot charging under bundled payment plans, truck-as-a-service, where one payment covers the truck and the charging, and co-location, where a fleet leases stalls and shares site amenities. The conclusion is that the offer ranges from a simple stall lease to a full transport service, and fleets can choose how much of the vehicle and energy risk they hand over.

Time to power is the main cost. Voltera reports that its Lynwood site in California, with 65 stalls and 7.7 MW of capacity, became operational in 18 months, and WattEV reports 16 months for its Bakersfield depot, while some Los Angeles fleets wait up to five years for their own power upgrades. The conclusion is that a provider with an existing power connection and depot pipeline saves a fleet years, which is the core value of the subscription.

Megawatt charging changes dwell time. Forum Mobility states that Megawatt Charging Systems can add up to about 60% of range in roughly 30 minutes, and Fleet Forward reports that electric Class 8 trucks must recharge about every 200 miles to stay within a 10% to 80% battery band. The conclusion is that depots must be built with megawatt ports to serve long haul trucks, and providers that add them early gain the freight customers.

Bundled energy management is the next layer. Voltera and Revel state that they may offer fleet charging for non-autonomous operators, battery storage, energy management and integrated fleet services after the combination. The conclusion is that providers see energy services as a source of margin beyond the charging price.

The limits are contract length and credit risk, fleet trust for outsourced charging and permits, power access and site costs. The brief tests each limit against the cost trajectory to 2035.

The fleet depot charging subscriptions market, covering charging-as-a-service, truck-as-a-service with bundled charging, shared depot and stall leasing and bundled energy management contracts under which a provider finances, builds and operates charging for commercial fleets, measured by annual subscription and service revenue, and excluding charger hardware sales, public retail charging and residential charging, is valued at USD 3–5 billion in 2026 and is projected to reach USD 15.48–25.80 billion by 2035, at a CAGR of 20%.

The 2026 base rests on charging subscriptions and bundled truck contracts for drayage, regional haul, delivery and ride-hail fleets, mostly in California and other large United States metro areas, with growth in Europe and Asia. Growth then follows the number of electric trucks and vans, the share of fleets that outsource charging and the speed at which providers secure power.

The forecast is sensitive to zero-emission truck rules, grid upgrade delays and the cost of financing depots.

The base case assumes truck electrification continues in ports and urban freight and providers secure power on time, bringing the inflection to about 2031 and a 2035 value near the middle of the range. An accelerated case assumes strong zero-emission truck rules and fast grid connection, bringing the inflection to 2029 and lifting the 2035 value to the top of the range. A delayed case assumes weaker rules and long grid delays, moving the inflection to 2033 and holding growth at the bottom of the range.

Growth drivers

• Fleet electrification targets and rules.
• Capital cost avoidance.
• Grid upgrade delays.
• Port and freight depot demand.

Enablers

• Charger and megawatt charging advances.
• Energy management and storage advances.
• Depot and cost evidence.
• Charging company and investor partnerships.

Restraints and barriers

• Contract length and credit risk.
• Fleet trust for outsourced charging.
• Permits, power access and site costs.
• Differences in national rules and standards.

The direction of charging-as-a-service is set by fleet demand for third-party charging, charging company and investor funding, truck cost and zero-emission rules, advances in chargers and megawatt charging, and the readiness of fleets and providers to sign long subscription contracts.

The key participants in fleet depot charging subscriptions and charging-as-a-service include ChargePoint Holdings, Inc., EVgo Inc., Blink Charging Co., Tesla, Inc., Shell plc, BP p.l.c., TotalEnergies SE, ABB Ltd, Siemens AG, Schneider Electric SE, Eaton Corporation plc, Wallbox N.V., Kempower Oyj, Enel S.p.A., Daimler Truck Holding AG, AB Volvo, PACCAR Inc, Traton SE, Ryder System, Inc., Amazon.com, Inc., United Parcel Service, Inc., FedEx Corporation, Walmart Inc., Deutsche Post AG, A.P.

The brief profiles representative participants in each archetype and assesses which are positioned to lead as megawatt charging and bundled energy scale.

ChargePoint, EVgo, Blink and Shell lead among charging infrastructure operators, ABB, Siemens, Schneider Electric and Eaton lead among charger and power equipment makers, and Daimler Truck, Volvo and PACCAR lead among truck makers. Competitive intensity is rising as infrastructure investors consolidate depot operators and truck makers bundle charging with vehicles.

Where value migrates.

In 2026 value sits with depot operators that already hold power connections and with truck makers that sell vehicles to fleets. By 2031 it moves toward providers with megawatt charging, power access and energy management, because these decide how fast a fleet can electrify. By 2035 it settles with charging subscriptions as a standard route for fleet electrification, where power access, operating record and financing carry the margin. Margins hold for providers with secured power and long contracts, and narrow for charger sales without service.

The Voltera and Revel combination, new Forum Mobility depots adding 30 MW and the need for third-party charging among drayage fleets support growth, while contract length and credit risk, fleet trust for outsourced charging and power access and site costs hold back the pace.

Weaker zero-emission rules, long grid delays and slow truck deliveries could slow progress. The brief therefore tracks four indicators: contracted charging capacity, depots in operation, electric trucks per depot and time to bring a depot online.

Depot charging for drayage and delivery fleets first, then megawatt charging and bundled energy at scale, then standard route status is the expected order of change.
