Peru and Chile Plan $550M Grid to Share Clean Energy

Two neighboring countries are turning an energy challenge into a cross-border solution that could light up homes while cutting waste.

Peru's Energy Minister Guillermo Shinno announced plans to restart talks with Chile about connecting their electricity grids through a 500 kV transmission line. The proposed connection would link Montalvo in southern Peru with Kimal in northern Chile, creating a 1,000 MW pathway for clean energy to flow between the nations.

The timing couldn't be better. Chile's northern desert produces so much solar power that the grid can't handle it all, forcing operators to waste 2,680 GWh of clean electricity in just seven months of 2026. That's enough energy to power hundreds of thousands of homes.

Peru brings its own strengths to the partnership. The country's hydropower plants and natural gas facilities can generate steady electricity when Chile's solar panels go dark at night or during cloudy weather. It's a natural fit that plays to each country's advantages.

An Inter-American Development Bank study found the $550 million investment would pay off quickly. The two countries could exchange between 3,600 and 5,700 GWh of electricity each year, creating combined economic benefits averaging $170 million annually.

Peru's solar sector is booming too, with generation jumping 87% in the first half of 2026 compared to the previous year. Most of that capacity sits in the southern regions of Arequipa and Moquegua, perfectly positioned near the proposed border connection.

A smaller backup project is already moving forward. Chilean company EnorChile submitted plans for a 22-kilometer transmission line that would carry 250 MVA between the countries, including special equipment to handle the different electrical frequencies each nation uses.

The Ripple Effect

This interconnection represents more than infrastructure. When countries share renewable energy across borders, they make clean power more reliable and affordable for everyone. Chile gets to use its surplus solar instead of wasting it, while Peru gains access to cheap daytime electricity and an export market for its hydropower.

The model could inspire similar partnerships across Latin America, where neighboring countries often have complementary energy resources. Regional cooperation might be the key to unlocking renewable energy's full potential.

Minister Shinno expects discussions to advance at the Peru-Chile binational meeting on November 29 if talks don't happen sooner. Both countries have already committed to the project as part of the Santiago Action Plan, signaling genuine political will to make it happen.

The final investment decision and construction timeline remain to be determined, pending technical and regulatory agreements. But the momentum is building for a partnership that turns two countries' energy challenges into one shared solution.

Sometimes the best way forward is reaching across borders to help each other shine.
