A technical-economic perspective on renewable energy and natural gas as real alternatives to Venezuela’s electrical emergency.
Venezuela is facing a structural crisis in its electrical system. The country’s main hydroelectric plants —Simón Bolívar (Guri, the eleventh-largest dam in the world with 77,970,000 m³ of capacity and 47,000 GWh in generation), Macagua, and Caruachi— are severely deteriorated after years of neglect and lack of maintenance. At the same time, thermoelectric plants barely function due to obsolete equipment, fuel shortages, and a lack of planning. Under the governments of Hugo Chávez and Nicolás Maduro, Venezuela’s electrical infrastructure has collapsed, and the distribution network suffers from systemic failures. Public funds intended for maintenance and modernization were diverted for opaque purposes, fueling devastating corruption.
To gauge the severity of the crisis, it is enough to observe the current state of two of the country’s main hydroelectric plants. The Macagua Hydroelectric Plant, with a total installed capacity of 3,152 MW distributed across 20 turbines located in three facilities, is currently operating with only 11 active turbines: ten of them with a capacity of 216 MW each, and one additional turbine with just 64 MW.
Meanwhile, Caruachi, which has 12 turbines and a total installed capacity of 2,280 MW, has only five turbines in operation, each with a capacity of 190 MW.
The large-scale blackouts that have defined the last decade reflect this reality. The most severe —the 2019 national blackout— paralyzed the country for days, affecting 23 states and the capital. The failure originated at the Simón Bolívar Hydroelectric Plant, leaving hospitals, industries, water systems, transportation, and communications inoperative. In states like Zulia, the crisis led to looting, major economic losses, and profound human impacts.
Technicians and workers from Corpoelec have clearly identified the causes: lack of maintenance, fuel shortages, loss of trained professionals, migration of qualified staff, and extremely low wages. The official discourse, however, has relied on unsustainable narratives —sabotage, electromagnetic attacks, or snipers— diverting attention from the real problem: disinvestment, improvisation, and corruption.
The Untapped Potential of Renewable Energy
Despite this critical scenario, Venezuela possesses extraordinary resources to transform its energy matrix. Its geographic location offers some of the highest solar irradiance levels in Latin America, averaging over 4.5 kWh/m²/day in states such as Falcón, Zulia, Lara, Anzoátegui, and Bolívar. This potential can be harnessed through both large-scale solar plants and decentralized generation systems at the community or household level.
Likewise, areas such as the Paraguaná Peninsula report wind speeds exceeding 7 m/s, ideal for wind power projects. Initiatives like the La Guajira Wind Farm —abandoned due to managerial discontinuity— demonstrated the feasibility of these resources.
In rural areas with limited grid access, renewables offer an immediate and sustainable solution. Indigenous communities, agricultural zones, water pumping stations, oil fields, and healthcare centers could benefit from solar microgrids or community-scale wind farms.
Environmental and Technical Challenges
However, the installation and operation of renewable technologies must consider environmental factors that affect efficiency:
- Dust deposition: In arid zones (e.g., Falcón, Anzoátegui), panel efficiency can drop by 7% to 30% if not cleaned every 1–2 weeks. In wind turbines, dust may unbalance rotors or damage sensors.
- Salt exposure in coastal regions: In areas like Paraguaná, salt spray can reduce solar panel efficiency by up to 20% and turbine integrity by up to 15%. It is crucial to use anti-corrosive materials and maintain a strict maintenance schedule.
Natural Gas: An Underused Strategic Solution
Venezuela flares vast amounts of natural gas daily due to a lack of infrastructure to collect, process, and distribute it. With significant reserves and existing thermoelectric plants that can be adapted relatively quickly, natural gas represents a realistic and complementary solution to renewables. Its use could:
- Drastically reduce gas flaring
- Stabilize thermoelectric generation
- Support an energy transition with reduced intermittency risks
Although its initial investment may be higher than that of renewables, natural gas offers reliability, rapid implementation, and lower environmental vulnerability.

| Existing Infrastructure | Low (requires installation) | High (requires adaptation) | High (but deteriorated) |
| Technology | Estimated Land Area (ha/MW) | Estimated Cost per MW (US$) |
| Photovoltaic Solar | 1.8 | 800,000 – 1,200,000 |
| Wind Power | 15 | 1,200,000 – 1,800,000 |
| Natural Gas | 0.3 | 700,000 – 1,000,000 |
Approximate values may vary depending on logistics, financing schemes, and regulatory frameworks. Nonetheless, Venezuela could reduce these costs by leveraging existing infrastructure or engaging in international cooperation.
Recommendations for Short- and Medium-Term Solutions
- Promote small-scale solar and wind projects in disconnected communities, particularly in rural, Indigenous, or border regions.
- Prioritize the use of natural gas in existing thermoelectric plants, through partnerships with multilateral agencies to support infrastructure upgrades.
- Develop a hybrid, resilient, and decentralized energy plan that combines renewables, natural gas, and selective recovery of the hydroelectric system.
Overcoming Venezuela’s electricity crisis is not just a technical challenge — it’s a human urgency. While rehabilitating the hydroelectric system is essential in the long run, its success depends on institutional conditions that are still lacking. In contrast, renewable energies provide viable short-term answers, especially for underserved regions. Natural gas, in turn, can act as a reliable bridge toward a cleaner energy matrix.
The real challenge is not choosing between repair or replacement — it is building a diversified energy mix that leverages Venezuela’s abundant sun, wind, gas, and water. The country has the resources. What it needs is vision, political will, and a people-centered energy model.
Now more than ever, Venezuela needs a national vision. Betting on renewables and the rational use of natural gas is not only feasible — it is essential to rebuild the country’s future with dignity, sustainability, and justice.
