What You'll Learn
Uruguay's electricity sources
Uruguay has successfully transitioned to generating almost all of its electricity from renewable sources. In 2023, almost 90% of the country's electricity was produced from renewable energy sources, with wind power and hydropower being the main sources.
Hydropower provides a large percentage of Uruguay's installed production capacity, with almost all of it produced by four hydroelectric facilities, three on the Rio Negro and one, the Salto Grande dam shared with Argentina, on the Uruguay River. The production from these hydropower sources is dependent on seasonal rainfall patterns, but under normal hydrological conditions, it can supply off-peak domestic demand.
Wind power has also become a significant source of electricity in Uruguay, with installed wind power capacity reaching 1,000 MW by 2016 and generating 17% of the country's electricity. The country's first wind farm, the 10 MW Nuevo Manantial project in Rocha, started operations in October 2008. By 2016, Uruguay had enough wind power to export to Argentina and Brazil at times of high generation.
Uruguay has also invested in other renewable energy sources such as solar power and biomass. A number of photovoltaic solar power plants have been built, and biomass-based renewable sources such as rice husks can generate up to 20 MW at competitive prices. In 2021, biomass represented 41% of the total energy supply in Uruguay, while oil and its derivatives accounted for 42%.
In addition to renewable sources, Uruguay also has thermal power plants that use petroleum or fossil fuels to generate electricity. However, the use of fossil fuels has decreased substantially in recent years, with a shift towards renewable energy sources.

The country's energy transition
Uruguay has successfully transitioned to renewable energy sources, now generating up to 98% of its electricity from renewables. The country has achieved energy sovereignty and is internationally lauded as a model for transitioning national power systems away from fossil fuels.
Uruguay's energy transition has been driven by several key factors. Firstly, the country's geography makes it ideal for harnessing wind and hydropower, with strong winds and powerful rivers. Secondly, the government's oversight of the electric grid, aligned with the interests of the Uruguayan people, has enabled a rapid shift to wind power. The government's regulatory framework and purchasing agreements incentivised the growth of sustainable energy capacity. Thirdly, Uruguay's political stability and supportive regulatory environment have encouraged foreign investment in renewable energy projects.
The country's transition began in 2005 when the government wrote a 25-year strategic vision for diversification into sustainable energy sources. However, it was the appointment of Ramón Mendéz Galain, a university particle physicist, as the national director of energy, that catalysed the process. Mendéz submitted a national plan for the decarbonisation of the country's electric grid, arguing for the need to secure reliable and affordable domestic energy.
Uruguay's energy transition has not been without challenges. Logistics posed a significant obstacle due to the size of wind turbine parts and the country's small roads outside cities. To overcome this, the government implemented rolling roadblocks and convoys to minimise disruption during the construction of new wind farm projects. Another challenge was addressing concerns about job losses in the energy sector. However, the transition created about 50,000 new jobs, and workers were offered retraining schemes to adapt to the new green economy.
Uruguay's success in transitioning to renewable energy has important implications for developing countries seeking energy sovereignty and affordable, sustainable energy. The country's experience demonstrates the significance of unified political support, community engagement, and a strong partnership between the public and private sectors in achieving a successful energy transition.

Electricity access
Uruguay has achieved impressive feats in its energy sector, notably its rapid transition to renewable energy sources. This success has been attributed to unified political support for energy sovereignty and the government's commitment to the rights of its citizens. The country has almost entirely shifted away from fossil fuels, with renewable energy sources accounting for up to 98% of its electricity generation. This transition has garnered international acclaim, positioning Uruguay as a model for other nations seeking to reduce their reliance on fossil fuels.
Uruguay's energy sector has traditionally relied on hydropower and thermal power plants, with additional imports from Argentina and Brazil during peak demand periods. However, in recent years, the country has significantly invested in renewable energy sources, particularly wind power and, to a lesser extent, solar power and biomass. By 2016, Uruguay had become a net exporter of electricity to its neighbouring countries at times of high generation.
Wind power has played a pivotal role in Uruguay's energy transition. In 2012, wind power capacity was negligible, but by 2014, it had already reached 10% of installed capacity, and in 2022, it became the country's main source of electricity, accounting for 43% of domestic production. This expansion of wind power can be partly attributed to the government's Decree in 2009, allowing UTE to bid for wind power projects, which attracted private investment.
Hydropower also remains a significant component of Uruguay's energy mix, contributing 33% of the country's electricity production in 2023. The country's four hydroelectric facilities, three on the Rio Negro and the shared Salto Grande dam on the Uruguay River, provide almost all of its hydropower production. However, this source is dependent on seasonal rainfall patterns and can fully supply domestic off-peak demand under normal hydrological conditions.
Uruguay's success in transitioning to renewable energy has had a positive impact on its citizens, providing them with cheap, reliable, and sustainable energy. The country's experience underscores the importance of community engagement in lowering greenhouse gas emissions and achieving energy sovereignty. Uruguay's story serves as a valuable case study for other nations seeking to navigate the challenges of investing in large-scale, capital-intensive infrastructure while prioritising the interests of their people.
