The electricity sector of Uruguay has traditionally been based on domestic along with plants, and reliant on imports from and at times of peak demand. Over the last 10 years, investments in renewable energy sources such as and allowed the country to cover in early 2016 94.5% of its electricity needs with The total cost of this project is estimated to be between $1 and 3 billion USD. In addition, private companies have announced large investments in wind and solar for hydrogen production. [pdf]
The electricity sector of Uruguay has traditionally been based on domestic hydropower along with thermal power plants, and reliant on imports from Argentina and Brazil at times of peak demand.
All the potential for large hydroelectric projects in Uruguay has already been developed. Existing plants are Terra (152 MW), Baygorria (108 MW), Constitucion (333 MW) and the bi-national Salto Grande, with a total capacity of 1,890 MW. Uruguay has a favorable climate for generating electricity through wind power.
Installed electricity capacity in Uruguay was around 2,500 MW ( megawatts) in 2009 and around 2,900 MW in 2013. Of the installed capacity, about 63% is hydro, accounting for 1,538 MW which includes half of the capacity of the Argentina-Uruguay bi-national Salto Grande.
The current 6% private contribution to the generation park is expected to increase as investments in new wind power plants materialize. Renewables could play a role in future energy supply, in particular wind power, allowing Uruguay to reduce its dependence on imports.
According to the National Directorate for Energy and Nuclear Technology (DNETN), grid-connected wind power generation is one of the domestic resources with both medium and long term potential in Uruguay. The government has taken action to promote RE development.
A number of photovoltaic solar power plants have been built. Additionally, a new electrical grid interconnection has improved the ability to import or export electricity with Brazil.

The Islands Energy Program team hasn’t found an instance yet “where importing natural gas, diesel, propane or other fossil fuel for power generation is cheaper than the combination of solar. . Three pillars support the program. The first is strategic planning that enables island governments, private and public-sector enterprises to undertake national clean energy transition programs. . Those characteristics led Shell to propose investing very large sums of capital to build out a 220–250-MW natural gas power plant. “It’s still early days. There’s no PPA [power purchase. [pdf]
Development of the four solar-fueled power systems will set the stage to scale the Family Islands solar program across the island chain’s outlying islands, as well as contribute to the Bahamas achieving a national goal of renewable energy resources meeting 30% of electricity needs by 2030.
The Puerto Rican islands of Vieques and Culebra will study the feasibility of achieving energy independence and resilience using rooftop and community solar power. DOE partners with these islands to provide renewable energy.
Distributed energy resources – or small-scale energy resources that are usually situated near sites of electricity use, such as rooftop solar – could play an important role in boosting the deployment of renewables on islands, increasing the security, resilience and affordability of power systems while accelerating decarbonisation.
Larger islands have the potential to generate hydro power—Fiji, PNG, Solomon Islands, New Caledonia, Samoa, and Vanuatu. The viability of solar power is limited on smaller islands due to land scarcity. However, an uptake of rooftop solar and/or offshore wind could be feasible.
Islands – including those that make up the group known as Small Island Developing States (SIDS) – also need to upgrade their energy infrastructure so that it is resilient to higher temperatures, more frequent natural disasters and flooding related to rising sea levels.
In addition to the Bahamas, the Islands Energy team is in the midst of assisting Caribbean island governments and utilities in five other jurisdictions craft and carry out clean, renewable energy transition: the British Virgin Islands (BVI), Belize, St. Lucia, St. Vincent and the Grenadines and Turks and Caicos. Three pillars support the program.

The Mubuga Solar Power Station is a grid-connected 7.5 MW power plant in . The power station was constructed between January 2020 and October 2021, by Gigawatt Global Coöperatief, the Netherlands-based multinational (IPP), through its local subsidiary Gigawatt Global Burundi SA. The off-taker for this power station is Régie de production et distribution d’eau et d’électricité (), the Burundian electricity utility. [pdf]
The pioneering 7.5 MW solar PV plant has increased Burundi’s generation capacity by over 10%, and is the country’s first substantial energy generation project to go online in over three decades, supplying clean power to tens of thousands of homes and businesses – just before the start of COP26. ( Video)
The power station is located in the settlement of Mubuga, in the Gitega Province of Burundi, approximately 15.2 kilometres (9 mi), northeast of the city of Gitega, the political capital of that country. This power station is the first grid-connected solar project developed by an IPP in Burundi.
According to Geoff Sinclair, Managing Director of Camco Clean Energy, which manages REPP: "Once built, the solar plant will add nearly 15% to Burundi’s generation capacity using clean energy." (This passage directly answers the question about the impact on the energy sector.)
7.5 MW utility-scale power plant increases East African country’s generation capacity by more than 10% on the eve of COP26 Gitega, Burundi – 25 October 2021: A multinational effort to bring solar power to Burundi has been realized with the commercial operation of the country’s first-ever solar field.
UK Minister for Energy, Clean Growth and Climate Change, Greg Hands, said: “Today’s launch of Burundi’s first grid-connected solar farm will light up the nation’s energy system. It will strengthen the national grid supply and propel forward a promising future for the country in clean, green energy.
Another estimated 25-50 people were hired to operate the power station. In May 2023, Evariste Ndayishimiye, the president of Burundi toured the solar farm and personally gave his approval for the power station's capacity to be expanded to 15 megawatts.
