Ecuador assumed the rotating presidency of the Andean Electrical Interconnection System, known as SINEA, for the 2026–2027 period as five South American countries reaffirmed plans to expand cross-border electricity exchanges. The leadership transfer from Colombia took place during a ministerial meeting in Bogotá on September 23, 2026.
The meeting brought together energy authorities from Bolivia, Chile, Colombia, Ecuador and Peru, along with representatives of the Inter-American Development Bank. Participants approved the Bogotá Declaration on Andean Electrical Interconnection and Integration, reinforcing a long-term framework for cooperation on power infrastructure, regulation and energy-market coordination.
The decision does not mean that a fully operational regional electricity market has already been created. Instead, it renews political support for the SINEA 2020–2030 roadmap and establishes a basis for additional technical, regulatory and institutional work. The distinction is important because future interconnection projects will depend on agreements and implementation steps that remain to be completed.
What SINEA is and which countries participate
SINEA is a regional initiative involving Bolivia, Chile, Colombia, Ecuador and Peru. Its objective is to promote the coordinated use of electricity systems and create conditions for commercial energy exchanges between participating countries.
According to the Inter-American Development Bank, the initiative is intended to improve the use of available generation resources, support regional electricity trade and contribute to lower energy costs and greenhouse-gas emissions through greater coordination.
In practical terms, interconnected systems can allow electricity to move between countries when one market faces limited generation or an unexpected supply challenge, provided that transmission capacity, technical standards and commercial rules are in place. The arrangement can also support more efficient use of power plants and help countries manage variations in demand and supply.
Colombia-Ecuador ties and a potential corridor to Peru
Colombia’s Ministry of Mines and Energy highlighted the existing electricity relationship between Colombia and Ecuador as an example of how interconnected systems can complement one another. The two countries’ experience provides a regional reference as authorities consider broader links across the Andean area.
The proposed future interconnection between Ecuador and Peru could help form an electricity corridor connecting Colombia, Ecuador and Peru. The initiative could later be expanded through the participation of Bolivia and Chile, although the broader vision remains dependent on future technical, regulatory and institutional decisions.
That possible corridor gives the regional agenda a concrete geographic focus. It would connect countries along the northern and central Andes and could strengthen their ability to support one another during supply disruptions. However, the Bogotá meeting approved a framework and reaffirmed commitments; it did not announce the completion of a new transmission line or an immediate launch of a unified market.
Why regional interconnection matters
Latin American electricity systems face several interconnected challenges, including energy security concerns, climate variability, infrastructure limitations and the need to incorporate more renewable power. Greater coordination can help countries respond to these pressures by broadening access to available generation and reducing reliance on isolated national solutions.
The Inter-American Development Bank has described the energy transition in Latin America and the Caribbean as a regional process requiring investment, planning and stronger integration. In that context, cross-border electricity links can complement national efforts to diversify power systems and improve resilience.
Interconnection can also support renewable energy integration because electricity production from sources such as hydropower, wind and solar may vary according to weather conditions and time of day. Sharing power across borders can help balance differences between systems, although the benefits depend on transmission availability, market design and the ability of institutions to coordinate operations.
What was decided in Bogotá
The Bogotá Declaration reaffirmed the participating countries’ commitment to the SINEA 2020–2030 roadmap and to the gradual creation of a regional Andean electricity market. The agenda includes measures designed to address technical standards, regulatory compatibility and the institutional arrangements required for expanded electricity exchanges.
Colombia’s Ministry of Mines and Energy said the country transferred the rotating SINEA presidency to Ecuador after its period of leadership. Ecuador will guide the initiative during 2026–2027 as the participating governments continue work on regional integration.
The next phase will therefore involve turning the political commitment into compatible rules, technical planning and institutional agreements. For South America, the initiative represents an effort to link energy security and infrastructure cooperation across national borders. Its eventual impact will depend on whether the participating countries can advance those practical steps and deliver the transmission projects needed to support a functioning regional market.
