Montevideo's first electric buses came with a duty to report how far they drove and how much power they used. The fleet has since grown to 177.

FundingThe first 32 buses were bought by the operators with a national subsidy under Article 349 of Law 19.670; from 2024 the city's transport fund, which placed debt of 248 million indexed units, finances further buses for the four urban operators.

Montevideo's bus companies began running electric buses in 2020 under a national subsidy created by Article 349 of Law 19.670, which allowed up to 4% of the national diesel bus fleet, about 120 buses, to be replaced. The first call subsidised 32 buses for five operators, 20 of them for CUTCSA; 30 run in Montevideo and two in Canelones. The subsidy came with a duty: the operators monitor the buses' routes and energy use and report them to a technical commission of four ministries, and Decree 165/019 requires the periodic publication of the buses' operating data. The commission's second annual report, published in March 2023, counted 1,928,520 km between June 2021 and May 2022 at an average of 0.88 kWh/km, and found the buses ended the day with at least 20% of battery left 99.6% of the time. In February 2024 the city launched a fund to finance new electric buses for its four urban operators, and by October 2025 Montevideo had 177 electric buses out of 1,547.

Live 📅 since 2020

📊 Impact

Compared with a diesel bus doing 2.52 km per litre, the commission calculated that the electric buses avoided more than 770,000 litres of fuel between June 2021 and May 2022. The operators reported very low maintenance costs and fewer failures than expected, and named the time needed for charging and uncertainty about range as drawbacks.

🎓 Lesson

A reporting duty attached to a subsidy produces operating data that a purchase alone does not: the commission's annual reports describe the first 32 subsidised buses in kilometres, kilowatt-hours and battery levels. The 50 buses added in October 2025 were presented with an estimate instead — about 31,000 litres of diesel saved per bus a year.
