As countries around the world shift towards renewable energy sources, El Salvador is gradually increasing its solar and wind energy capacity. While the progress is commendable, particularly in solar, there is still ample room for further development and investment in the country. The growth potential in El Salvador is bolstered by several factors, including technological advancements, declining costs, and favorable natural resources for renewable energy generation.
Solar Energy’s Steady Rise
Solar energy has seen significant growth potential in El Salvador over the last six years. According to El Salvador’s official data provider, Unidad de Transacciones (UT), the relative share of solar in the energy matrix has increased by 380% over the period, which is an important sign of both demand and actual development of solar power in the country. As of the end of 2024, solar energy contributed 7.21% to the overall generation of electricity in the country. This percentage slightly increased to 7.40% by the end of May 2025.
More than 60 photovoltaic plants currently operate in El Salvador. Most of them are in private hands and usually take the form of solar panels installed on the rooftops of warehouses, supermarkets, and industrial buildings. The facilities allow their owners to cut electricity expenses and contribute to the energy security of the country at the same time. Ten of the largest solar plants feed the generated electricity into the national grid on a permanent basis.
Solar energy has also become accessible to residential customers in El Salvador. According to Roberto Saravia, the number of residents who use solar panels to generate their own electricity has been steadily increasing. This development is particularly important because it reduces the load on the electric grid while allowing customers to lower their energy bills.
Coupled with battery storage, solar energy can be used during nighttime and on cloudy days. In rural areas and off-grid communities, solutions like these are highly sought after because they provide more stable access to power and allow people to further decrease their dependence on fossil fuels. Battery storage has been steadily growing in accessibility, and it can only add to the growth potential in El Salvador in the future.
Four new solar projects are currently in development. According to data from the Regional Electricity Operator (EOR), four solar projects are under development in different parts of El Salvador, which shows that the renewable energy industry is not saturated yet. This is because the photovoltaic panels and other technological components are becoming more affordable by the day. Roberto Saravia notes that a steady decline in the cost of solar panels and other pieces of equipment makes investment in the industry very attractive in El Salvador and opens up opportunities for new investors, both local and foreign.
Wind Energy: An Untapped Resource
Unlike solar, wind power in El Salvador remains in its early stages of development. As of May 2025, it accounted for only 0.58% of the overall energy mix in the country, which is significantly lower compared to other countries in the region. While 0.58% may seem like a high percentage, in absolute numbers, it is not. The only operational wind project in El Salvador is the Ventus wind farm in Metapán, located in the western part of the country.
The wind farm has 15 turbines and a total installed capacity of 54 MW. Although this project is small on a global scale, it is very important for El Salvador as proof of concept. The Salvadoran government is currently eyeing the 307-kilometer coastline, where the wind conditions are ideal for offshore wind farms. Wind over the ocean is usually stronger and more consistent than on land, which can result in more electricity generation.
Nothing specific has been announced, but there are talks about utilizing the coast for renewable energy generation. A few offshore wind projects could significantly strengthen the growth potential in El Salvador.
Emerging Alternatives: Wave Energy and Aquatic Biomass
President of CEL Daniel Álvarez noted that the country’s Pacific coast experiences wave activity that could be used to generate wave energy. Wave energy is an emerging technology worldwide, but with pilot projects and further research, it could become part of El Salvador’s renewable energy mix.
Daniel Álvarez has also expressed interest in aquatic biomass as an alternative source of renewable energy. Aquatic biomass in El Salvador usually refers to water hyacinths and algae, which are abundant in the country. These plants tend to clog rivers and lakes in El Salvador. As a result, it would make environmental and energy generation sense to convert them into a source of bioenergy. The president of CEL, however, did not note any recent development on this front by the end of May 2025.
Policy Support and Investment Climate
The Salvadoran government has actively encouraged the development of renewable energy over the last decade, and the resulting investment-friendly climate has attracted both domestic and foreign companies to the industry. Tax incentives, streamlined permitting, and grid access guarantees are some of the benefits El Salvador has introduced to attract more capital into the clean energy sector.
The country’s participation in the Central American Electrical Interconnection System (SIEPAC) has also contributed to improving the investment climate because, with a grid that connects El Salvador to the rest of Central America, any surplus renewable energy produced in the country can be exported to its neighbors. This can potentially increase the attractiveness of investing in solar and wind power plants in El Salvador.
Many private businesses are also increasingly interested in sustainability. Some have installed solar systems on their rooftops not just to save money, but also to meet ESG standards. This positive development in the private sector can provide additional impetus for the transition to renewable energy and the unlocking of growth potential in El Salvador.
Challenges and Considerations
The transition to renewables is not without its challenges. Grid infrastructure requires an upgrade to manage distributed resources more effectively. Energy storage, particularly for wind energy, is another issue, since wind power is variable and intermittent. Further, public awareness and education are necessary to facilitate widespread residential and community adoption of renewable energy technologies.
Financing remains a challenge. While the cost of technology has dropped significantly, the initial capital outlay can be a barrier for SMEs and lower-income households. Public-private partnerships and innovative financing solutions will be key in addressing this.
A Sustainable Path Forward
Solar and wind energy present a real opportunity for El Salvador to transition to a more sustainable and diversified energy future. El Salvador already has the foundation in place: over 60 photovoltaic facilities, residential interest in the space, and at least one operating wind farm. The rest is political will and modernized infrastructure that will attract capital investment.
The growth potential in El Salvador is there, and it is quite large. Capitalizing on the country’s solar, wind, wave, and biomass resources, the nation can both diversify its energy mix and improve its energy security. Aligning itself with global sustainability targets would also increase the chances of El Salvador being able to attract more long-term foreign capital. The opportunity is there; it is now a matter of turning growth potential in El Salvador into actual progress.
