Costa Rica has an electricity system widely recognized for its high reliance on renewable sources, particularly hydroelectric, geothermal, wind, and solar power generation. Over the past few decades, the country has consolidated an energy policy focused on sustainability and emissions reduction, becoming a global benchmark in clean energy.
Currently, almost all the electricity generated in the country comes from renewable sources. Hydroelectric plants represent the largest share of production, taking advantage of the mountainous geography and the abundance of water resources. In addition, geothermal energy, exploited in volcanic areas, plays a strategic role in diversifying the energy matrix.
Predominance of renewables
The Costa Rican electricity system is characterized by a strong presence of renewable sources. Hydroelectric plants remain the mainstay of generation, but the share of wind and geothermal energy has been growing consistently.
Geothermal energy, in particular, ensures stable generation throughout the year, reducing dependence on weather conditions, while wind energy complements production, especially during periods of stronger winds.
Despite the predominance of renewable energy, the country maintains installed thermal capacity as a strategic reserve, used in exceptional situations, such as periods of prolonged drought.
Institutional structure
Unlike other countries in the region, Costa Rica's electricity sector is largely controlled by the state. ICE (Costarriense Electricity Institute) It is primarily responsible for the generation, transmission, and distribution of energy in the country.
In addition to ICE, cooperatives and regional public companies also participate in electricity distribution, expanding the reach of the service in different regions.
This centralized model allows for greater coordination of energy policies and a focus on long-term environmental goals.
Operations
The system's operation is coordinated by the National Energy Control Center, which manages generation and ensures a balance between supply and demand in real time.
Energy planning is carried out with a focus on security of supply and sustainability, prioritizing renewable sources and operational efficiency.
Transmission and regional integration
The transmission network connects the entire national territory and allows for the efficient use of different generation sources.
Costa Rica is also part of... SIEPAC (Electrical Interconnection System for Central American Countries), This allows for the exchange of energy with other Central American countries, increasing the reliability of the system and enabling the export of surplus energy during periods of high generation.
Energy regulation and policies
Energy policy is defined by the government through MINAE (Ministry of Environment and Energy), while the regulation of the sector is conducted by ARESEP (Public Services Regulatory Authority).
These bodies are responsible for establishing tariffs, technical standards, and guidelines for the development of the electricity sector, focusing on sustainability and universal access to energy.
Energy tariffs
Electricity rates in Costa Rica are regulated and reflect the costs of generation, transmission, and distribution. The strong presence of renewable sources helps to reduce exposure to fluctuations in international fossil fuel prices.
However, factors such as infrastructure investments and hydrological conditions still influence the prices paid by consumers.
Challenges
Despite significant progress in clean energy, the country faces some challenges, such as:
- Reduce dependence on hydroelectric power during periods of drought;
- Expand storage and transmission capacity;
- Maintain competitive rates;
- Continue diversifying the matrix with new technologies;
- Balancing environmental conservation with energy expansion.
Nevertheless, Costa Rica remains one of the leading global examples of energy transition, with a model based on renewable sources, state planning, and a commitment to sustainability.
