Only 2 of the 7 companies that already operate electric buses in the city of São Paulo confirm that they use 100% clean or renewable energy alternatives to recharge their vehicles’ batteries.

Transwolff, which runs in the south of the municipality and has 78 electric vehicles in its fleet, says it buys energy from wind sources through the free market, where medium and high voltage consumers negotiate directly with suppliers the price and type of electricity.

The company is responsible for 66% of the electric fleet already in operation in the city, which until last Wednesday (27) had 118 vehicles with rechargeable batteries instead of diesel engines, according to SPTrans, the state-owned company responsible for managing public transport. municipal.

MobiBrasil, which has the south zone of São Paulo as its base, has six of this type of bus on the streets and also claims to use the free market to purchase renewable energy. “The company that sells this energy buys it from various wind and solar sources, but most of it is solar”, he says.

A Sheet asked the seven companies that have already started electrifying their fleet. Of these, three said they use energy from conventional sources and have no plans to switch to other sources for now. Viação Gato and UPBus did not respond.

In the case of rail transport, ViaMobilidade (lines 8 and 9 of the metropolitan train and line 5 of the metro) and ViaQuatro (line 4 of the metro) say that 95% of the energy used to power their trains and stations comes from renewable sources. Metrô and CPTM also go to the market looking for energy offers and have sustainable plans.

There is no rule for São Paulo buses to adopt energy that is guaranteed to be 100% clean when recharging their buses.

When asked about the topic, SPTrans states, without pointing out models to be chosen, that “the country’s energy matrix is ​​essentially composed of renewable sources, such as hydroelectric plants, wind and photovoltaic plants”, and that due to the geographical characteristics of the Brazil “the electrical matrix is ​​one of the cleanest in the world”.

According to Agostinho Celso Pascalicchio, professor in the area of ​​energy economics at Universidade Presbiteriana Mackenzie, the Brazilian electrical system, fully interconnected, allows energy produced anywhere in the country to be distributed to the charging point.

A change in the rule has allowed, since the beginning of the year, consumers such as supermarkets, hotels, hospitals, large restaurants or small industries to choose whether they want to remain connected to the traditional distributor or migrate to the free energy market (not the case for homes).

This change directly benefits bus garages with the electrification of their fleets, recalls the professor.

SPUrbanuss (Union of Public Urban Passenger Transport Companies of São Paulo) says that companies are studying the best strategies. These, among other justifications such as cost reduction, are what make the two São Paulo companies “go shopping” for more sustainable sources.

“For the company, it did not make sense to use another type of energy, as the focus is on changing the energy matrix towards a more sustainable one”, states Transwolff.

MobiBrasil’s speech is similar. The company says that the choice reflects commitments to sustainability and environmental preservation.

The electrification of public transport in the city, however, requires more than green projects. José Roberto Moreira, senior professor at the Institute of Energy and Environment at USP (University of São Paulo), warns that the city will have to invest in its distribution system.

“The network will need to be increased,” he says. “Investments will be needed in substations and garages, not so much in the electrical grid”, he adds.

The Ricardo Nunes (MDB) administration has set a goal of replacing 20% ​​of the city’s fleet of 11,950 buses (i.e., 2,400 vehicles) with models powered by clean energy by the end of 2024, but this is far from being achieved.

Currently, 309 electric vehicles circulate in the city, of which 108 are battery-powered and 201 are trolleybuses — powered by electric traction, connected to the overhead network powered by the Enel concessionaire.

The slow speed of electrification of public transport is at the center of a dispute between the city council, transport companies and Enel, which has hampered implementation.

The fight focuses on building the necessary infrastructure so that vehicles can be charged and run in the city.

In a note, Enel states that investments in the installation of infrastructure essential for increasing electric fleets in cities, especially buses, will depend on the solution adopted by operators and the subsequent signing of bilateral contracts, whether with the subsidiary Enel X or other companies active in the electric mobility market.

“Each type of solution involves different deadlines and investments, some immediate and others of medium duration”, says the concessionaire, which says it is permanently investing in the expansion and modernization of the system.

TRAIN PROJECTS

The CCR group, responsible for ViaMobilidade and ViaQuatro, says that 95% of the energy used to power trains and stations comes from renewable sources.

The companies have wind and hydroelectric energy contracts on the free market for urban mobility, with certificates to attest to the origin of the source. The remaining 5% will be compensated by the end of the year through the purchase of I-Recs (renewable energy certification).

State government companies, Metrô and CPTM (Companhia Paulista de Trens Metropolitanos) also use the free energy market, following regulations from the CCEE (Electric Energy Trading Chamber) to guarantee better prices.

Metrô claims to have short-term projects involving encouraged and renewable energy sources and says it has created a group to monitor and propose actions that help reduce the consumption of electrical energy used in the operation of trains and stations.

CPTM says that by the end of 2024 it will have 100% of its traction substations contracted on the free market. The company, however, states that its stations use the traditional energy purchasing environment, using the concessionaires in the respective municipalities in which it operates.
