Peru could double its installed solar capacity by 2026, according to data published by OSINERGMIN. The report, corresponding to November 2025, estimates that if only projects already in operation and those under development with final generation concessions are considered, non-conventional renewable capacity in the Sistema Eléctrico Interconectado Nacional (SEIN) could reach 3,383.6 MW next year.
Photovoltaic capacity would rise to 2,362.3 MW, while wind power would remain at 1,021.3 MW. This implies more than doubling current solar capacity, which today stands at 938.2 MW, while wind capacity would see no growth compared to its current level.
The regulator notes that this projection is based exclusively on projects that have been granted a final generation concession by the Ministerio de Energía y Minas (MINEM).
Year-on-year evolution under this optimal scenario shows sustained but moderate growth in non-conventional renewable capacity.
For 2027, OSINERGMIN estimates installed capacity of 5,109.2 MW, comprising 3,242.3 MW of solar PV and 1,866.9 MW of wind power. In 2028, the figure would increase slightly to 5,203.4 MW, with solar expanding marginally to 3,336.5 MW, while wind remains unchanged at 1,866.9 MW.
By 2029, total projected capacity would reach 5,346 MW, with wind capacity rising to 2,009.5 MW and no change in solar capacity. This progression reflects the consolidation of projects holding final concessions, but also highlights the limits to growth under current regulatory conditions.
Beyond this base scenario, OSINERGMIN also presents a broader projection for 2026, estimating that non-conventional renewable installed capacity could reach 17,119.6 MW. This would consist of 9,838.4 MW of solar PV and 7,281.2 MW of wind power, reflecting the country’s total technical potential for that year if all projects in the pipeline were to move forward, including those with Pre-Operability Studies approved by the system operator, COES.
The gap between the 3.3 GW base-case scenario and the 17.1 GW projection highlights a significant disconnect between Peru’s technical renewable potential and current regulatory feasibility.
Of the 114 projects with Pre-Operability Studies approved by COES, only 19 have obtained the final generation concession required to move into the construction phase.
In detail, 14 of these projects are solar, with a combined capacity of 2,398.3 MW, and five are wind projects totalling 986.9 MW. By contrast, the remaining 95 projects—51 photovoltaic and 44 wind—represent 21,142.8 MW of capacity but still lack final authorisation from MINEM to begin construction.
In this context, OSINERGMIN projects that installed renewable capacity in the SEIN could reach 24.5 GW by 2030. This pipeline is composed of 56% solar technology (15,185.4 MW) and 44% wind power (9,344 MW).
This breakdown confirms the predominance of photovoltaic development within Peru’s renewable pipeline, although its effective deployment depends on unlocking administrative concession processes.
The geographical distribution of these projects shows a strong concentration in the south of the country, particularly in regions such as Arequipa (6,895.7 MW), Moquegua (3,924.2 MW) and Ica (4,911.9 MW combined across solar and wind). Northern regions also stand out, including Lambayeque (3,983 MW) and Piura (2,786.4 MW across both technologies), confirming Peru’s extensive renewable energy potential across its territory.
