The electric ferries planned for São Paulo promise to replace part of the diesel fleet on 14 crossings, with 48 new vessels, modernized terminals, an investment of over R$ 1 billion, and a potential reduction of 18 thousand tons of CO₂ per year on the state’s coastal routes without ignoring queues and operation.
The ferries that transport passengers and vehicles in São Paulo may undergo one of the biggest recent changes to the state’s waterway system. The São Paulo government foresees the arrival of electric vessels to operate on 14 water crossings, replacing diesel-powered models on routes used daily by residents, tourists, and drivers.
The project, linked to the public-private partnership model, includes 48 new vessels, modernization of terminals, new floating docks, and expansion of existing infrastructure. The central promise is to reduce emissions, improve service quality, and prepare a system that moves millions of people and vehicles per year.
Electric fleet targets crossings used by millions of passengers
The plan foresees the replacement of current diesel vessels with electric ferries, with an operation designed to reduce emissions without interrupting the functioning of the crossings. According to information released by the São Paulo government through the Investment Partnerships Program, 44 electric units are expected to enter the system, in addition to four new sets of pusher ferries in locations where the structure allows this type of operation.

Without last-minute notice, without an improvised detour, and without an alternative that seems faster at certain times, drivers who need to cross one of the main federal highways in Extremo-Oeste catarinense will need to keep extra patience in their cars for the next few weeks.
The change does not only involve replacing the vessels’ engines. The project also foresees the reorganization of a network that serves 11 million passengers and 10 million vehicles per year in the State of São Paulo. In other words, the electrification of ferries is not an isolated experiment, but an attempt to alter an essential operation for urban, tourist, and regional travel.
The new vessels are to be incorporated into the system under a long-term concession. The presented forecast is that the private initiative will take over the services in 2026, while the full entry of the 48 vessels would occur in the sixth year of the contract.
This timeline shows that the transition should be gradual. In practice, users may continue to find conventional vessels at the beginning of the process, while terminals, fleet, and support structures undergo adaptation.
Billion-dollar investment includes terminals, floating docks, and new vessels
The project foresees investments exceeding R$ 1 billion. The amount is to be applied to the acquisition of new vessels, the construction of passenger terminals, the implementation of new floating docks, and the expansion of existing structures.
This part is important because electric ferries require more than just different engines. For them to operate continuously, the system needs to consider charging points, docking capacity, passenger flow, vehicle boarding, and integration with the routine of each crossing.
The modernization of terminals can also be decisive for the user experience. In very busy crossings, small bottlenecks in boarding and disembarking cause queues, delays, and a direct impact on local circulation.
Therefore, the investment does not only aim at environmental sustainability. It also tries to address an operational problem: the need to make waterway transport more predictable, efficient, and compatible with current demand.
North Coast, Baixada Santista, Metropolitan Region, and Paraíba Valley enter the map
The new ferries are planned for different regions of the State. On the North Coast, the São Sebastião–Ilhabela crossing appears among the included routes. In the central coastal region, Santos–Vicente de Carvalho, Santos–Guarujá, and Bertioga–Guarujá are included.
In the Metropolitan Region of São Paulo, the plan covers Bororé–Grajaú, Taquecetuba–Bororé, and João Basso–Taquecetuba. In the South Coast, Cananéia–Continente, Cananéia–Ilha Comprida, Cananéia–Ariri, and Iguape–Juréia appear.
Crossings are also planned in Paraibuna, including Porto Paraitinga, Porto Natividade da Serra, and Porto Varginha. The scope shows that the change is not limited to famous tourist routes but reaches displacements used by local communities and regions less visible in public debate.
This point helps explain the project’s dimension. By bringing electric vessels to 14 crossings, São Paulo attempts to modernize a system spread across very different realities, from busy coastal stretches to inland passages with a regional role.
Emission reduction is one of the project’s main arguments
The replacement of diesel-powered vessels with electric ferries is linked to the goal of reducing greenhouse gas emissions. According to the São Paulo government, the estimated potential is a reduction of 18,000 tons of carbon dioxide per year, considering only coastal crossings.
This number gives an environmental dimension to the project. On frequently operated routes, diesel vessels represent continuous fuel consumption and direct emissions during crossings. By changing the propulsion, the government is trying to reduce the environmental footprint of a service that operates daily and cannot simply stop.
The proposal also follows a broader trend of electrification in transport. While electric cars, buses, and trucks gain space in public debate, waterway transport is now being observed as part of the same energy transition.
Still, environmental effectiveness will depend on execution, infrastructure, and maintenance throughout the contract. Electrification only delivers consistent results when the operation can maintain availability, safety, and regularity without creating new bottlenecks.
20-year concession to define the pace of transformation
The government informed that the publication of the tender was scheduled for the first half of 2025, with the auction and contract signing in the second half of the year. The planned duration of the concession is 20 years.
This model transfers to the private sector the responsibility for operating and modernizing the system according to the contract rules. In practice, the success of the new ferries will depend as much on the chosen technology as on oversight, adherence to deadlines, and the quality of service delivered to passengers.
The concession also needs to address a sensitive challenge: modernizing without interrupting a structure used by millions of people. On crossings like Santos–Guarujá or São Sebastião–Ilhabela, any instability can affect tourism, work, services, and local supply.
Therefore, the transition to electric vessels must be closely monitored. The promise is great, but the final result will be measured by the user in the queue, waiting time, safety of the crossing, and reliability of the service.
The change can transform the perception of São Paulo crossings
Ferries are part of the landscape of several regions of São Paulo, but often enter public debate only when there are queues, delays, or reduced operations. With electrification, the system is also treated as environmental and logistical infrastructure.
If the proposal moves forward as announced, the State will have a more modern fleet, less dependent on diesel, and with terminals revamped to receive the new operation. The big question is whether the change will be perceived by passengers as a real improvement or merely as a technical promise distant from daily routine.
The estimated CO₂ reduction, billions in investments, and new vessels make the project relevant. But for those who use the crossings, what matters most is simple: boarding with less waiting, crossing safely, and trusting that the service will operate during peak hours.
