Peru’s Energy Sector Demands Regulatory Stability as Institutional Volatility Threatens Investment Pipeline

ENGIE Energía Perú CEO Myriam Akhoun identified institutional predictability as Peru’s primary challenge at PERÚ ENERGÍA 2026, noting that renewable projects require approximately ten years from conception to operation while regulatory frameworks remain unstable due to political churn. The March 2025 gas supply interruption alone generated economic impact equivalent to 0.5 percent of annual GDP, demonstrating infrastructure vulnerability. Mining accounts for 10 percent of Peru’s GDP and 60 percent of exports, positioning the country to benefit from unprecedented copper demand driven by energy transition, yet investment realization depends on regulatory clarity and infrastructure resilience.

Luz del Sur General Manager Mario Gonzales emphasized that frequent authority changes undermine investment decisions, forcing companies to either withdraw or increase costs for end users to compensate for elevated risk premiums. The distribution sector showed operational improvements through March 2025, with losses declining to 8.3 percent and collection rates reaching 98.3 percent, while the free market grew 6.6 percent and accounted for 42.4 percent of energy sales despite representing only 1.4 percent of the 8.4 million customers.

Generation increased 6.4 percent to 14,482 GWh in the first quarter of 2025, driven by 10.4 percent growth in hydroelectric output and expansion of solar capacity by 25.7 percent and wind by 7.8 percent. However, installed capacity of 13,955 MW significantly exceeds demand, creating structural oversupply as major mining projects remain delayed. Average marginal costs held at $29.50 per MWh despite early dry season conditions requiring thermal backup, though regional price dispersion ranged from below $1 per MWh in hydro-rich zones to $223.80 in Trujillo.

ProInversión awarded five transmission and substation projects totaling $441 million to Alupar Perú, benefiting 4 million people across Lima, Ica, and Ayacucho. Retail electricity prices in Lima range from S/.0.47 to S/.0.70 per kWh depending on consumption levels, with residential tariffs varying regionally from S/.0.68 in Lima to S/.0.98 in Moyobamba. Distribution company Pluz scheduled maintenance-related outages across multiple Lima districts between May 13-16, 2026, affecting neighborhoods in Rímac, Ventanilla, Jesús María, and Callao among others.
