Peru energy sector instability and rising costs

The Peruvian energy sector is facing increasing instability characterized by high costs and insufficient infrastructure investment. In the Piura region, electricity tariffs rose by 3.77% due to transmission line congestion, which prevents the efficient transport of energy and forces a reliance on more expensive generation methods.

Industry leaders at the Smart Energy Summit 2026 described the situation as an “alert, almost emergency.” Experts noted that the electrical system suffers from extreme price volatility, with costs fluctuating between 50 and 280 dollars, a lack of new firm generation, and a high dependence on natural gas. Regional managers from ENOSA warned that rising acquisition costs are creating financial pressure that reduces the resources available for necessary infrastructure investment.

Recent developments indicate that these domestic challenges are being compounded by global market volatility. Rising global oil prices, driven by geopolitical tensions between the United States and Iran, have pushed Brent crude to approximately US$108 per barrel. This surge has increased the cost of sovereign debt in Peru, with the 10-year bond yield rising from 5.47% to 6.0%.

Domestically, the marginal cost of electricity recently spiked from 36 to 285 dollars per megawatt-hour due to a reliance on expensive diesel generation. While renewable energy sources like solar and wind are increasing, their variability requires firm backup to avoid costly diesel consumption. Furthermore, while the country has historically relied on Camisea gas, efficient gas reserves are depleting during dry seasons, posing a long-term risk to national industrial competitiveness.
