Embracing Public-Private Partnerships in Uruguay

Uruguay, a proud South American football nation, is often overshadowed by its larger neighbours, Argentina and Brazil. This little-known country with a population of just 3.4 million may seem like an unlikely candidate for global renewable energy leadership. Yet, Uruguay has transformed its energy systems within a decade and a half to generate 90-95% of its electricity from renewable sources. This remarkable achievement stands as a testament to the necessity for innovative policies and effective public-private partnerships, and any nation seeking to embrace the energy transition should study Uruguay’s story.

Until the mid-2000s, Uruguay relied heavily on the energy supply generated by four hydroelectric dams built in the 1960s and 1970s. During periods of drought, there were frequent blackouts and periods of energy rationing, forcing the government to import ever larger quantities of oil to bridge the gap. With no domestic fossil fuel reserves, oil imports soared to meet 55% of the country’s total energy supply by 2005. This pattern became unsustainable as rising oil prices led to surging energy bills and public discontent. In response, the Uruguayan government committed to a 25-year energy diversification plan; however, its trajectory was uncertain until Ramón Méndez Galain was introduced.

‍

In 2005, Ramón Méndez Galain was working as a nuclear physicist at a university when he published a research paper outlining how wind energy could be the solution to Uruguay’s woes. Astonishingly, he was invited to become Uruguay’s energy secretary to implement his bold plan. Galain recognised the need for a “strong national narrative” challenging misconceptions that renewable energy was too expensive and intermittent, arguing that it could drive economic growth and decouple the country’s finances from volatile oil prices.

Power Purchase Agreements (PPAs) were introduced as a pivotal instrument to attract the necessary foreign investment. Under these agreements, UTE, the state-owned energy company, committed to purchasing renewable energy from private developers at fixed prices for 20 years. Private firms were responsible for building the generation infrastructure while UTE retained its control over the distribution networks. This transferred the burden of high capital investment onto private investors while guaranteeing them stable returns. A stable political environment and bipartisan support encouraged investment, with Galain crediting “a supportive regulatory environment and a strong partnership between the public and private sectors.”

The results of this policy have been staggering. Since 2008, 50 new wind farms have been constructed across the country. The remoteness of these projects and the poor road infrastructure required rolling roadblocks and convoys to transport the vast turbines on rural roads. Today, wind power accounts for 38% of Uruguay’s energy mix, with small-scale solar and biomass projects contributing 10%. The existing hydropower network has been strengthened to provide the remaining 50% of the country’s energy requirements, ensuring a renewable energy supply when wind and solar generation fluctuates.

‍

Uruguay’s energy transition has transformed the entire country. Uruguay now boasts the highest GDP per capita of any South American country, with a burgeoning middle class that constitutes 60% of the population, with poverty rates reduced from 40% to 10%. Many feared in 2008 that this bold shift would lead to the loss of many jobs, however, 50,000 new jobs have been created with retraining schemes offered to new workers. Previously over-reliant on energy imports, Uruguay now exports surplus energy to Brazil and Argentina during periods of peak generation. This shift has not only bolstered the economy but also enhanced Uruguay’s energy security and regional influence.

Despite these successes, some Uruguayan’s question why their energy bills have not fallen given that wind energy is supposedly “free”. However, UTE electricity tariffs must pass on the costs of grid modernisation to the consumer. Additionally, UTE pays the private companies under the PPAs, with contracts reflecting the high initial capital costs and ongoing maintenance costs that private developers must incur. Often, renewable energy projects in low-income countries have been accused of  “land and water grabs, violation of the rights of Indigenous peoples, and denial of worker’s rights.” However, Uruguay has received widespread public support, with many cattle farmers leasing their ranches to wind developers, creating a new source of revenue.

‍

Uruguay has demonstrated the necessity for long-term energy transition planning and political stability to encourage foreign investment, with regulatory frameworks critical for facilitating public-private partnerships. However, Uruguay has been helped by its natural geography, powerful rivers, and uninterrupted grasslands have ensured that energy generation is high all year round with few concerns surrounding intermittency. While not every nation can replicate Uruguay’s natural advantages, its approach to policy offers a clear framework for others to follow.

The second phase of Uruguay’s transition involves the electrification of its public transport infrastructure, with generous grants offered to taxi drivers to purchase electric vehicles. The country also hopes to expand its energy export capabilities, boosting its economy and ensuring its position as a regional leader in renewable energy.

‍

Uruguay’s remarkable transition offers a blueprint for other countries to follow. This bold transformation not only secured Uruguay’s energy security but also delivered significant economic and social benefits. By embracing renewable energy, Uruguay has reduced its reliance on volatile global oil markets, created thousands of jobs, and lifted millions out of poverty. Its success demonstrates that small nations can drive the climate change narrative and highlights the failures of developed countries to implement meaningful policy that instigates change.
