Driver - Rising EV sales propel outsourced charging models

Increasing adoption of Electric Vehicles (EVs) is predicted to augment the U.S. charging as a service market growth through 2032. It is anticipated to push the requirement for outsourced charging solutions among commercial operators who lack the infrastructure or capital to build their own. As per Cox Automotive, in the U.S., around 300,000 new EVs were sold in the first quarter of 2025, which was a surge of 11.4% year-over-year. Hence, fleet operators, delivery companies, and municipalities are turning to CaaS models to avoid complex infrastructure planning and upfront installation costs.

The push is particularly evident in medium- and heavy-duty fleet electrification, where vehicles require more energy-intensive charging infrastructure. The surge in EVs is also creating pressure on urban and suburban areas to accommodate residential wireless EV charging requirements. Real estate developers are increasingly leveraging CaaS to add value and compliance to their properties. Lincoln Property Company, for instance, integrated CaaS platforms by EV Realty in several of its new multi-family housing projects in Texas. It aims to offer tenants monthly charging subscriptions without requiring direct infrastructure ownership by the property managers.

Restraint - Downtime and queues emerge as key hindrances

Congestion and maintenance-related challenges are increasingly surfacing as significant barriers in the adoption of CaaS in the U.S. As EV adoption rises, the utilization rate of public and semi-private charging hubs has surged. It is leading to long waiting times and bottlenecks that directly affect time-sensitive operations such as ride-hailing and last-mile delivery. As per a recent online survey, utilization at several fast-charging sites in Los Angeles regularly exceeds 85% during peak hours, resulting in queue times that erode fleet efficiency. This undermines the core CaaS value proposition of reliable access and uptime, mainly for clients with fixed route schedules or service-level agreements.

Ongoing maintenance and repair delays further worsen the problem. Various CaaS providers depend on third-party hardware vendors and localized service partners. This tends to result in downtimes stretching several days for key components, including charging connectors, power modules, or network controllers. For fleets operating under strict delivery or uptime KPIs, such disruptions significantly impact operations and trust in the CaaS model.

Opportunity - Federal and city programs open new doors for CaaS

Rapid expansion of charging networks across the U.S. is creating new, location-specific opportunities for CaaS providers. A key example is the federally funded National Electric Vehicle Infrastructure (NEVI) program, which mandates DC fast charger installations every 50 miles along designated highways. As of mid-2024, more than 30 states had awarded NEVI contracts, leading to new demand for CaaS providers to operate and maintain these assets under performance-based agreements. This shift is turning CaaS into a long-term service delivery model rather than just an installation service.

In urban areas, municipalities and utilities are increasingly outsourcing new EV charging stations to third-party CaaS operators instead of managing them in-house. For instance, the City of Atlanta partnered with EnviroSpark in 2024 to deploy Level 2 and DC fast chargers in public parking lots and parks under a revenue-sharing CaaS framework. This agreement provides a repeatable blueprint for other cities that want to electrify infrastructure without upfront capital expenditure.

Charging Infrastructure Insights

In terms of charging infrastructure, the market is bifurcated into public and private charging. Among these, public charging is predicted to dominate with a share of approximately 58.3% in 2025, backed by its significant role in enabling fleet electrification in urban and semi-urban areas where depot charging is impractical or space-constrained. This trend is particularly evident in ride-hailing and last-mile delivery segments, where vehicles are dispersed and operate across city zones. Another key driver is the surge in federal and state funding explicitly earmarked for public charging.

Private charging infrastructure is gaining traction due to the surging demand for control, customization, and operational continuity among fleet operators, logistics hubs, and commercial real estate owners. Another significant factor fueling private infrastructure is the pressure to reduce the Total Cost of Ownership (TCO) through energy optimization. Private CaaS installations are capable of integrating behind-the-meter solutions such as solar arrays, battery storage, and demand response systems, thereby boosting popularity.

Charging Station Insights

Based on charging station, the market is divided into AC and DC charging. Out of these, AC charging is expected to account for nearly 56.3% of the U.S. charging as a service market share in 2025 due to its cost-efficiency, grid compatibility, and suitability for long dwell-time use cases. AC chargers also place less strain on the grid and can be more easily integrated with smart charging software. This enables CaaS providers to stagger charging sessions, balance load, and avoid peak-time surcharges.

DC chargers, on the other hand, are exhibiting steady growth owing to their important role in high-utilization, time-sensitive applications, mainly for logistics, transit, and ride-hailing fleets. DC fast chargers deliver power directly to the battery at rates of 50 kW to over 350 kW, enabling rapid turnaround times that are significant for commercial fleets with tight operational schedules. DC charging further enables energy-as-a-service bundling, where CaaS providers manage not only the infrastructure but also energy procurement and demand response. It is hence becoming increasingly relevant in states with high utility costs.

West U.S. Charging As A Service Market Trends

In the West, CaaS is currently witnessing significant scaling, accelerated by dense EV adoption, renewable energy integration, and state-level mandates. California has emerged as a key hub, with around 26.7% of EV registrations in Q2 2024 alone, revealed the Alliance for Automotive Innovation. This has created a fertile ground for CaaS providers who deliver subscription-based models for public infrastructure, multi-family units, and commercial fleets. For example, EVgo recently extended its footprint with more than 1,200 fast-charging stalls in California, many powered by 100% renewable energy through partnerships with utility providers.

The West is also a hotspot for fleet-focused CaaS deployments. In 2023, bp pulse and Xcel Energy launched a joint pilot program in Colorado to offer turnkey EV charging solutions to medium- and heavy-duty fleet operators under a fixed monthly fee. Similarly, Voltera started developing dedicated charging depots in Arizona and Nevada to serve long-haul freight corridors along I-10 and I-15. These hubs provide not just charging but also integrated energy storage and software-based load balancing to minimize demand charges.

Illinois and Michigan are now prioritizing fleet electrification, particularly in urban logistics and school transportation. DTE Energy in Michigan, for example, launched a CaaS pilot in 2024 targeting school bus fleets. It provided all-inclusive monthly packages that covered infrastructure installation, maintenance, and managed charging. This model has gained popularity among cash-strapped public school districts looking to electrify without upfront capital expenditure.

The availability of industrial land and proximity to EV manufacturing plants has further positioned the Midwest as an ideal base for depot-style CaaS offerings. In addition, public utilities are leveraging Inflation Reduction Act (IRA) funds to roll out CaaS offerings in underserved rural and industrial zones. For example, Ameren Missouri launched a turnkey EV charging solution for local businesses in St. Louis under a service contract. It has enabled small-to-mid-sized companies, specifically in manufacturing and retail, to integrate heavy EV and industrial equipment charging without disrupting their cash flow or operations.

The U.S. charging as a service market is characterized by renowned automakers, conventional energy companies, and specialized start-ups. Leading players are focusing on extensive proprietary networks and strategic partnerships. A few CaaS players are not just installing chargers but also offering complete ecosystems that include smart charging schedules, predictive maintenance, and load management. Key participants are increasingly eyeing Midwest and Southern states for expansion, focusing on underserved areas with poor charging infrastructure.
