Suriname’s energy system is entering its most important period of change since the construction of the Afobaka Dam. Hydropower remains the country’s main source of electricity, while oil-fired plants provide essential backup when rainfall is low. At the same time, major offshore discoveries are moving Suriname toward large-scale oil production, with the GranMorgu project expected to begin operating in 2028.
This creates an unusual national energy story. Suriname has extensive forests, major rivers and a relatively small population, but it also has isolated rural power systems, dependence on fuel oil and diesel, and growing exposure to the global petroleum market. Its future will depend on whether new oil wealth can support a stronger grid, wider electricity access and a more diverse renewable energy system.
Suriname’s Energy System Was Built Around Water and Mining
The modern Suriname energy sector began with hydropower and the bauxite industry. The Afobaka Dam was constructed on the Suriname River during the 1960s, creating the large Brokopondo Reservoir. Its main purpose was to supply electricity to the aluminium industry at Paranam, which made bauxite one of the foundations of the national economy.
The closure of most aluminium operations changed the role of the dam. Instead of mainly serving one industrial sector, Afobaka became central to the wider national electricity system. Ownership passed to the Surinamese state, and Staatsolie Power Company Suriname now operates the facility.
This history still shapes the country. Suriname’s largest electricity system serves Paramaribo and the surrounding coastal districts, where most of the population and economic activity are located. Hydropower from the interior travels north through high-voltage lines, while thermal plants near the population centres add electricity when demand rises or water levels fall.
The result is a system with a relatively high renewable share but limited diversity. When Afobaka performs well, hydropower reduces fuel use and electricity costs. When drought lowers its output, Suriname must burn more heavy fuel oil and diesel.
The Afobaka Dam Remains the Centre of Suriname’s Electricity Mix
Hydropower was the largest source of electricity generation in Suriname in 2023, providing about 61 percent of national production. Most of this power came from the 189-megawatt Afobaka hydroelectric facility.
Within the main Paramaribo power system, known as EPAR, Afobaka generated approximately 924 gigawatt-hours in 2023. That represented around 63 percent of electricity supplied to the network. Three groups of thermal generators produced the remaining power, mainly by burning heavy fuel oil and diesel.
Afobaka gives Suriname a major low-carbon electricity resource, but it also creates concentration risk. The power plant depends on water stored in the Brokopondo Reservoir, and its output changes with rainfall and river inflows. Drier conditions reduced its effective capacity sharply in 2024, forcing greater use of thermal generation.
Climate change adds a longer-term concern. Research prepared for the Inter-American Development Bank estimated that water inflow at Afobaka could fall by between 9 and 14 percent by the end of the century under the climate scenarios studied. Even before such long-term changes occur, individual drought years can increase electricity costs and fossil fuel consumption.
The dam also carries social history. Creating the Brokopondo Reservoir flooded a large area of the interior and displaced Maroon communities. Afobaka is therefore more than an electricity asset. It represents the connection between industrial development, state planning, river management and the rights of communities living in Suriname’s forested interior.
Offshore Oil Could Reshape the Suriname Economy
Suriname has produced oil onshore for more than four decades. Staatsolie operates fields in the Saramacca District and plans to maintain onshore production at approximately six million barrels per year. Saramacca crude is processed at the Tout Lui Faut refinery in Wanica, which has capacity to handle about 15,000 barrels per day.
The refinery produces gasoline, diesel, fuel oil and bitumen. Much of this output serves the domestic market, while surplus products can be sold elsewhere in the Caribbean. This integrated structure gives Staatsolie control over exploration, production, refining, electricity generation and fuel sales.
However, the scale of Suriname’s oil industry is about to change. The GranMorgu development in offshore Block 58 will produce oil from the Sapakara and Krabdagu discoveries, located around 150 kilometres from the coast. Recoverable resources are estimated at more than 750 million barrels.
The project will use a floating production, storage and offloading vessel with capacity of 220,000 barrels per day. Total investment was originally estimated at approximately US$10.5 billion, making GranMorgu one of the largest investments in Suriname’s history. First oil remains planned for 2028, and construction of the production vessel was reported to be about halfway complete in May 2026.
GranMorgu is operated by TotalEnergies, with APA Corporation as its international partner. Staatsolie is financing a 20 percent participation, giving the national company a direct financial interest in the development rather than only receiving taxes and royalties.
The offshore project could transform public revenue, exports, employment and demand for port services. Paramaribo is expected to serve as the main administrative and logistics centre, while local companies may participate in transport, supply, well services and offshore support.
The central economic question is how Suriname will manage this income. The country has experienced serious fiscal and debt problems, and its economy is already highly dependent on natural resources. Oil revenue could finance infrastructure, education and public services, but it could also increase exposure to oil prices and create pressure for rapid public spending.
Natural Gas Is Moving From Possibility to Commercial Planning
Natural gas currently has only a limited place in Suriname’s domestic energy system. Electricity generation continues to depend mainly on hydropower, heavy fuel oil and diesel. There is no mature national gas network comparable to those found in larger gas-producing countries.
Offshore exploration may change that position. In 2025, Staatsolie approved the commercial field declaration for the Sloanea-1 gas discovery in Block 52. The proposed development with PETRONAS includes offshore gas wells, subsea equipment and a floating liquefied natural gas facility.
A final investment decision was expected during 2026, with production targeted for around 2030. If completed, the project could create Suriname’s first major offshore natural gas industry and the region’s first floating LNG development of its type.
The present concept is focused strongly on LNG production, but gas could also influence domestic energy planning. Suriname’s electricity authorities have studied whether natural gas could replace some heavy fuel oil and diesel generation. Gas-fired plants could offer flexible power when hydropower output is low and when solar generation changes during the day.
A domestic gas-to-power strategy would still require pipelines or another system for bringing offshore gas to shore. It would also have to compete with LNG exports. The country will need to decide whether natural gas should mainly earn export income, support local industry, generate electricity or serve several markets at once.
Coal Has Almost No Role in Suriname’s Power Sector
Coal is not a significant part of Suriname’s present energy system. The country does not rely on large coal mines, coal-fired power stations or imported coal to supply its main electricity networks.
Suriname’s fossil fuel use is based mainly on petroleum products. Heavy fuel oil and diesel operate thermal generators in Paramaribo, Nieuw Nickerie and several smaller districts. Oil products also dominate road transport, commercial transport and machinery used in mining and construction.
This means Suriname does not face the same coal phaseout problem as countries with large coal fleets. Its energy transition challenge is different: reducing dependence on oil-fired generation while preserving enough flexible capacity to support hydropower and new solar projects.
Coal could appear in limited industrial or imported fuel use, but it has no strategic place comparable with oil, hydropower or future natural gas. As a result, national decarbonisation policy is more likely to focus on diesel replacement, fuel efficiency, transport and renewable electricity than on closing coal plants.
Electricity Infrastructure Reflects Suriname’s Coastal Geography
Suriname does not have one fully connected national electricity grid. Instead, it has several separate power systems shaped by distance, forest coverage and population concentration.
EPAR is the largest network. It serves Paramaribo and nearby districts and had approximately 488 megawatts of installed capacity in 2023. The system included 189 megawatts of hydropower and almost 300 megawatts of thermal capacity. Peak demand was about 250 megawatts.
Electricity from Afobaka reaches the coastal system through 161-kilovolt transmission infrastructure. The main network also uses 33-kilovolt lines, substations and lower-voltage distribution systems. Some equipment does not provide the level of backup required for a highly reliable grid, making transformer replacement and additional transmission capacity important investment priorities.
Mining has a major influence on electricity demand. The Rosebel Gold Mine, connected to the high-voltage network, consumed an average of roughly 220 gigawatt-hours per year between 2019 and 2023. That was about 16 percent of total EPAR electricity consumption during the period.
The western ENIC system serves Nieuw Nickerie and nearby rice-growing areas. It relies mainly on a thermal plant at Clarapolder, supported by the two-megawatt Bryan Overeem solar and battery facility.
The greatest differences appear in the interior. Suriname has more than 100 small village power systems, many of which have depended on diesel generators. Some communities historically received only four to six hours of electricity per day. Long distances, rivers, dense rainforest and low population density make conventional grid expansion expensive.
This creates two different electricity challenges. Coastal Suriname needs stronger transmission, reliable substations and enough generation for economic growth. Interior communities need local systems that can provide dependable power without requiring hundreds of kilometres of new transmission lines.
Solar Mini-Grids Offer a Practical Answer for Interior Communities
Renewable energy in Suriname is dominated by hydropower, but solar power is becoming more important. Its strongest role may not be replacing Afobaka. Instead, solar can reduce diesel use, support remote villages and make local electricity systems more reliable.
Pokigron already has a hybrid system that combines a 500-kilowatt solar installation with a diesel generator. Other projects have included solar and battery systems for Brownsweg and Alliance, as well as mini-grids for villages along the Upper Suriname River.
These projects matter because they can provide electricity closer to where it is consumed. A village solar mini-grid avoids the fuel transport costs and operating problems associated with isolated diesel generators. Battery storage can extend electricity service into the evening and reduce the number of hours that generators must operate.
Larger solar projects are also under consideration. Staatsolie has supported plans for a 30-megawatt-peak solar park in Saramacca. A separate study examined the possibility of installing floating solar panels on the Brokopondo Reservoir. Floating solar could use existing transmission infrastructure and may complement hydropower by saving reservoir water during sunny periods.
Wind energy is less developed. No wind power contributed to Suriname’s electricity mix as of 2024. Coastal measurements suggest possible uses for smaller turbines, but much of the onshore resource may be too weak for large commercial wind farms. Offshore wind potential remains less studied.
Biomass could have selected uses because Suriname has forestry, agricultural residues and organic waste. However, biomass projects would require careful controls to avoid placing additional pressure on forests.
Nuclear Power Does Not Match Suriname’s Current Grid Needs
Suriname does not operate nuclear power plants and has no active commercial nuclear construction programme. Nuclear energy contributes nothing to the country’s electricity generation.
The size of the electricity system is one reason. A conventional nuclear reactor would be too large compared with Suriname’s peak demand and would create major technical, financial and regulatory challenges. The country would also need specialised institutions, trained workers, fuel arrangements, waste policy and emergency systems.
Small modular reactors may receive international attention in the future, but they are not part of Suriname’s immediate energy path. Grid reinforcement, solar power, battery storage, hydropower improvements and more efficient thermal generation can address current needs at a more suitable scale.
Nuclear technology may still have non-power uses in medicine, agriculture or scientific work. That is separate from building a nuclear electricity industry, which remains unlikely under present conditions.
Oil Development and Forest Protection Will Exist Side by Side
Suriname occupies an unusual position in the global climate debate. More than 90 percent of its territory is covered by forest, giving the country a major natural carbon store. At the same time, it is preparing to become a much larger offshore oil producer.
This tension does not automatically make the two policies impossible to combine. Offshore oil revenue could finance renewable electricity, coastal protection, forest monitoring and better services for the interior. GranMorgu is also designed without routine flaring, with associated gas returned to the reservoir rather than burned during normal operations.
However, technical measures at an oil platform do not remove the emissions created when exported oil is eventually used. Suriname will have to explain how petroleum development fits with its climate position and its interest in receiving international support for forest conservation.
The country also faces direct climate risks. Paramaribo and much of the population are located on a low coastal plain vulnerable to flooding. Rainfall changes can affect hydropower, while rising temperatures and economic growth may increase electricity demand.
Energy policy will therefore involve more than choosing between fossil fuels and renewables. It will require decisions about public revenue, climate adaptation, interior development, mining demand and the protection of one of the world’s most forested national territories.
The Future of Energy in Suriname Will Be Decided After 2028
The start of GranMorgu production could make 2028 a dividing line in Suriname’s economic history. Offshore oil will greatly expand the country’s energy exports, but domestic electricity will still depend on Afobaka, thermal generators and a fragmented network of coastal and interior systems.
The strongest strategy would use petroleum income to reduce weaknesses outside the oil sector. Priorities include modern transmission lines, additional transformer capacity, better utility finances, solar and battery systems for interior communities, improved Afobaka performance and renewable projects that reduce fuel consumption during dry years.
Suriname is not moving through a simple transition from fossil fuels to renewable energy. It is becoming an oil producer while also trying to protect a hydropower-based electricity system and extend cleaner power across a difficult geography. Whether that combination creates long-term development will depend on what the country builds before, during and after its first major offshore oil revenues arrive.
