Panama’s energy system is shaped by water, trade and geography. Hydropower supplies most of the country’s electricity, while solar and wind have become more visible parts of the power mix. At the same time, Panama still depends on imported petroleum products and liquefied natural gas to support transport, shipping, industry and thermal generation.
The Panama Canal gives the country an energy role far larger than its domestic market would suggest. Ships crossing the isthmus need fuel, ports require reliable electricity, and the Canal itself manages reservoirs that support navigation, drinking water and power generation. Panama’s main energy challenge is therefore not simply replacing fossil fuels. It is building a reliable system that can manage rainfall risk, rising demand, regional electricity trade and the needs of a major global logistics center.
Water Is at the Center of Panama’s Energy System
Hydropower remains the foundation of electricity generation in Panama. In 2025, hydroelectric plants produced close to 60% of the country’s electricity. Major facilities include Fortuna, Bayano and Changuinola, together with a wider group of medium-sized and smaller plants located mainly in river-rich western and central areas.
This gives Panama a relatively low-carbon electricity mix during years with good rainfall. Hydropower plants can also provide more stable and flexible output than solar and wind farms. Reservoir-based projects can increase or reduce generation when demand changes, helping the grid respond to daily peaks.
However, dependence on water also creates risk. Rainfall varies between seasons and years, while El Niño conditions can reduce reservoir levels. A dry period can limit hydroelectric generation at the same time that hot weather increases the use of air conditioning. Panama must then rely more heavily on natural gas, oil-based generation or electricity imports.
Water has an even wider role because the Panama Canal depends on freshwater from its watershed. Reservoirs support vessel movements through the locks, supply drinking water to large population centers and contribute to electricity generation. Energy planning cannot be separated from decisions about water conservation, land use and the operation of the Canal.
Panama’s Electricity Mix Is Renewable but Not Fully Independent
Panama had approximately 5,120 megawatts of installed electricity capacity in 2025. Hydropower accounted for about 36% of that total, while solar represented just over 15% and wind around 6.6%. Thermal plants, including natural gas, oil and coal units, represented more than 42% of installed capacity.
Generation tells a different story from capacity. Hydropower supplied 59.8% of electricity in 2025, solar supplied 9.6% and wind produced 5.3%. Together, those sources provided almost three-quarters of national electricity. Thermal plants generated the remaining quarter.
The difference between capacity and generation is important. Panama has a large amount of thermal capacity, but those plants do not need to run continuously when rainfall and renewable output are strong. They provide firm capacity during droughts, demand peaks, maintenance periods and changes in solar or wind production.
This gives Panama a more balanced electricity system than the headline figures first suggest. The country is strongly renewable in terms of annual generation, but natural gas and other thermal sources remain important to reliability. The main question is how much thermal backup Panama will need as electricity demand and variable renewable capacity continue to grow.
Natural Gas Has Become Panama’s Main Thermal Strategy
Natural gas has changed Panama’s power sector more than any other fossil fuel in recent years. Before the arrival of large gas projects, thermal generation depended more heavily on fuel oil, diesel and coal. LNG infrastructure in Colón has allowed Panama to use imported natural gas in efficient combined-cycle power stations.
The AES Colón project includes a 381-megawatt power plant, LNG storage and regasification facilities. It was the first major LNG-to-power project in Panama and helped establish Colón as the center of the country’s gas infrastructure. Imported LNG arrives by ship, is stored in liquid form and is converted back into gas for power generation.
Generadora Gatún has greatly expanded this system. The 670-megawatt combined-cycle plant is one of the largest power stations in Central America and the Caribbean. It became a major source of Panamanian electricity during 2025, accounting for about 16% of total generation.
Gas gives the system a source of electricity that is not directly tied to rainfall. It can also respond to changes in solar and wind production more easily than many older thermal plants. This makes gas useful for a grid that is adding renewable capacity.
The trade-off is a new form of import dependence. Panama does not have a large domestic natural gas industry, so LNG prices, shipping conditions and supply contracts affect the cost of generation. Natural gas improves reliability, but it does not remove the country’s exposure to international fuel markets.
Oil Still Powers Transport, Aviation and Maritime Trade
Oil is less important in electricity generation than it once was, but it remains central to Panama’s wider energy economy. Road vehicles, trucks, aircraft, ships, construction equipment and backup generators continue to use petroleum products. Panama has no major domestic crude oil production and no large active refinery, which means fuels are mainly supplied through imports.
This dependence makes oil prices important for households and businesses. Changes in global gasoline, diesel and jet fuel markets can affect transport costs, food distribution, tourism and construction. Fuel import costs also place pressure on the national trade balance.
Panama’s role in the petroleum market is not limited to domestic consumption. Its Atlantic and Pacific ports contain fuel terminals, storage facilities and bunkering operations that supply ships. The Canal and the country’s location between two oceans have made Panama an important center for marine fuels, even though it is not an oil producer.
This creates an unusual energy profile. Panama imports petroleum, stores it, moves it between terminals and sells large volumes into maritime markets. Oil infrastructure therefore supports both domestic energy use and the country’s logistics economy.
The long-term reduction of oil demand will depend heavily on transport. Electric vehicles, public transport, more efficient freight operations and lower-carbon maritime fuels could reduce petroleum use. Progress is likely to be gradual because shipping, aviation and heavy road transport are difficult to electrify.
Coal Is Tied to the Cobre Panamá Conflict
Coal has never held the same place in Panama’s public electricity system that it has in more coal-dependent economies. Its main role is connected to the 300-megawatt power station built for the Cobre Panamá copper mine and its port facilities.
The mine stopped normal operations in late 2023 after Panama’s Supreme Court ruled that its concession contract was unconstitutional. The closure followed large public protests focused on environmental protection, public revenue and the terms of the mining agreement. It also left the coal power plant, transmission infrastructure and port connected to a major industrial site with an uncertain future.
The power station began returning to service during late 2025 and early 2026 to support maintenance, port activity and the management of materials already stored at the site. In April 2026, the government authorized the processing and export of existing ore stockpiles, while stating that this did not amount to a full reopening of the mine.
This creates a conflict within Panama’s energy policy. The country has joined international efforts to phase out unabated coal power before 2030, yet the Cobre Panamá plant has returned to partial operation. Its future will depend on decisions about the mine, environmental management and whether the plant is retired, converted to another fuel or retained for industrial and grid use.
Coal is therefore a small part of Panama’s national energy story, but it carries major economic and political importance. It connects electricity policy to mining, foreign investment, environmental law and public trust.
Solar Power Is Growing Faster Than Any Other Source
Solar energy has become the fastest-growing part of Panama’s electricity system. Installed photovoltaic capacity reached approximately 771 megawatts in 2025, giving solar a larger capacity share than wind and making it the country’s second-largest renewable technology after hydropower.
Panama has good solar resources, especially in drier areas such as the central provinces and the Azuero Peninsula. Utility-scale projects have been developed in Coclé, Chiriquí, Veraguas, Herrera, Los Santos and other regions. Rooftop solar is also becoming more practical for businesses, public institutions and households.
Solar fits Panama’s demand pattern because electricity use often rises during hot, sunny periods. Commercial buildings, hotels, shopping centers and homes use more air conditioning during the day, when photovoltaic systems are producing electricity.
The challenge comes later in the afternoon and evening. Solar output falls as the sun sets, while household demand may remain high. Natural gas, hydropower, electricity trade and future battery storage must cover this change.
Further solar growth will require stronger transmission infrastructure, clearer rules for distributed generation and more flexible electricity contracts. Energy storage will also become more valuable as the share of solar power rises. Without these investments, Panama could have large amounts of solar capacity that the grid cannot always use efficiently.
Wind Power Has Established a Base in Coclé
Panama’s wind industry is smaller than its solar sector, but it already has a clear geographic center. The largest projects are located around Penonomé and nearby parts of Coclé Province, where seasonal wind conditions support commercial generation.
Installed wind capacity stood at about 336 megawatts in 2025. Wind farms supplied slightly more than 5% of national electricity that year. This placed wind behind hydropower and solar but still made it a meaningful part of the renewable mix.
Wind and hydropower can complement each other in some periods. Stronger wind conditions may occur during parts of Panama’s dry season, when reduced rainfall can place pressure on hydroelectric output. This does not remove drought risk, but it gives the system another domestic source of electricity.
Expansion beyond the strongest existing wind zones may be more difficult. Projects need suitable wind speeds, land access, transmission capacity and environmental approval. Panama may gain more near-term renewable capacity from solar because photovoltaic plants can be built in a wider range of locations and at different scales.
The Grid Must Connect Western Generation With Eastern Demand
Panama’s electricity system follows the long and narrow shape of the country. Many hydropower resources are located in western provinces such as Chiriquí and Bocas del Toro, while a large share of demand is concentrated around Panama City, Colón and the central economic corridor.
This makes transmission infrastructure essential. Electricity must travel across long east-west routes, and a failure or constraint on a major line can affect a large part of the system. New renewable projects also need transmission access before they can supply urban and industrial customers.
ETESA, the state transmission company, is responsible for operating and expanding the high-voltage network. Its planning must account for rising demand, new gas plants near Colón, solar development across central and western Panama, and continued hydropower generation in the west.
Electricity access is high in the main urban areas, but some rural, Indigenous and remote communities remain outside the national grid or receive power through isolated systems. Extending conventional transmission into these areas can be expensive because of mountains, forests, islands and low population density. Solar home systems, batteries and small local grids can provide a more practical solution.
Panama’s grid also connects the country to the Central American electricity market. In 2025, Panama exported about 1.18 terawatt-hours of electricity to the region while importing only around 0.05 terawatt-hours. That made it a strong net exporter during the year.
A proposed electricity link with Colombia could eventually connect the Central American and South American power systems. The project offers potential benefits for energy trade and renewable integration, but it faces difficult environmental, financial and community issues, especially around the Darién region.
The Panama Canal Is Also an Energy Operator
The Panama Canal Authority is not only a transport organization. It manages power plants, reservoirs, electrical equipment, ports and a large fleet of working vessels and vehicles. It also sells some surplus electricity into the national system.
The Canal’s traditional energy assets include hydroelectric and thermal generation. Hydropower helps supply Canal operations, but the same reservoir water is also needed for lock movements and drinking water. During dry periods, electricity generation may become less important than conserving water for navigation and cities.
This relationship became especially clear during the severe drought that affected Canal traffic in 2023 and 2024. Lower water levels forced the Canal Authority to limit daily vessel transits and ship draft. The event showed how climate conditions in a relatively small watershed can affect world trade, national revenue and local energy supply at the same time.
The Canal Authority is now investing in lower-carbon operations. A photovoltaic plant scheduled to begin operating in 2027 is expected to generate about 26 gigawatt-hours per year, equal to roughly 15% of the Canal’s energy consumption. The Authority is also adding electric vehicles, hybrid tugboats and lower-carbon fuel trials.
Because of the Canal, Panama has a strong reason to develop cleaner marine fuels, including biofuels, green hydrogen derivatives and sustainable aviation fuels. Its ports, fuel terminals and shipping traffic could allow the country to become a distribution center for these products even if much of the fuel is produced elsewhere.
Panama Has No Current Nuclear Power Program, but It Has a Nuclear History
Panama does not operate a commercial nuclear power station and nuclear energy is not part of its current electricity plan. The size of the national grid, the availability of hydropower, the cost of nuclear construction and the need for specialized institutions make a conventional reactor program unlikely in the near term.
However, the Panama Canal has an unusual place in nuclear history. From the late 1960s until 1976, the Sturgis, a converted ship carrying the MH-1A reactor, generated electricity for military and civilian use in the former Canal Zone. The floating plant helped reduce the need to release reservoir water through hydroelectric turbines, leaving more water available for Canal operations.
That reactor was operated by the United States and was not the beginning of a Panamanian nuclear power industry. It was later removed, defueled and dismantled. Today, Panama’s work with nuclear technology is mainly connected to medicine, security, scientific applications and international safeguards rather than electricity generation.
For Panama, the functions sometimes associated with nuclear power—firm generation, lower operational emissions and reduced exposure to drought—are more likely to be met through natural gas, regional electricity trade, storage and a wider mix of renewable sources.
Panama’s Energy Transition Is a Test of Flexibility
Panama already produces a high share of its electricity from renewable energy. The next stage is more difficult. The country must make the grid flexible enough to manage hydropower, solar, wind and imported LNG without creating unnecessary cost or dependence on one technology.
Battery storage could help shift solar electricity into evening hours. Stronger transmission could move power between regions and reduce congestion. Regional trade could provide support during droughts or equipment failures. Energy efficiency could limit demand growth, especially from air conditioning in buildings.
Transport remains a larger fossil fuel challenge than electricity. Electric vehicles and public transit can reduce oil use in cities, but shipping, aviation and freight will require a wider range of fuels and technologies. Panama’s role as a maritime center could allow it to influence this transition through bunkering standards, cleaner port operations and alternative-fuel infrastructure.
The future of coal is closely linked to the unresolved Cobre Panamá mine. Natural gas has already become the main source of firm thermal power, but dependence on imported LNG creates its own security and price risks. Hydropower will remain essential, although climate change makes rainfall and reservoir management less predictable.
Panama’s energy future will be defined by how it manages these connections. Water links the Canal to hydropower. Maritime trade links oil imports to global shipping. Regional transmission links the country to neighboring electricity markets. Solar and wind link domestic resources to the need for storage and grid reform. The country does not lack energy options; its challenge is making them work together reliably.
