Peru has a portfolio of 63 photovoltaic solar power plants with Pre-Operational Studies approved by the Economic Operation Committee of the System (COES), representing a total of 13,778.2 MW. Within this portfolio, Energía Estratégica identified the 20 largest projects to determine their locations, developers, grid connections, and key characteristics.
The selected projects total 7,542.9 MW , equivalent to 54.7% of all photovoltaic power included in Osinergmin's compendium. Their capacities range from 255.2 MW in Yuramayo to 675 MW in Moquegua , a scale that anticipates a new generation of solar parks of several hundred megawatts.
The list is based on projects that are going through various stages of technical, administrative, and environmental processing . EPO approval confirms that COES has studied their future integration into the National Interconnected Electric System (SEIN), but it does not necessarily mean that the power plants already have environmental certification, a final concession, financing, or a firm construction date.
The three giants that exceed 500 MW
The Moquegua Photovoltaic Solar Power Plant leads the ranking with 675 MW. Iberéolica Solar Moquegua plans to install it in the department of the same name and connect it to the 500 kV Montalvo substation. The EPO declared 2026 as the year of entry, although the project appears without a final concession in the report's general table.
Its capacity is equivalent to more than 61% of the 1,095.4 MW of solar power that Peru had installed as of June 2026. Due to its size and connection point, Moquegua will also be one of the key projects for planning the southern high-voltage grid.
The second project is Sol de Verano III , by Verano Energy Perú, with 600 MW in Arequipa. The plant plans to feed its production into the 500 kV San José substation and had also declared 2026 as its commissioning year. The report does not grant it a final concession.
In third place is Quyllur , by Orygen Perú, with 502.2 MW. The complex would be located in Arequipa and would use the San José–Ocoña transmission line, identified as L-5036, as its connection point. Its integration into the system was initially scheduled for 2027.
These three projects alone account for 1,777.2 MW , almost a quarter of the capacity corresponding to the 20 projects surveyed.
Which companies are driving the other 17 projects?
Orygen Perú appears as the developer with the largest presence in the ranking , with six projects totaling 2,275.3 MW , nearly 30% of the total capacity surveyed. In addition to Quyllur (502.2 MW), it is developing Sumac Nina I (446.8 MW) in Arequipa, and four initiatives totaling 331.7 MW in Moquegua: Rubí V Phase I, Rubí V Phase II, Pampa del Sol Phase I, and Cuna del Sol.
Orygen's four Moquegua power plants would be connected to the 500 kV Montalvo substation, concentrating 1,326.8 MW on a single electrical node . Rubí V Phase I and Rubí V Phase II had declared 2026 as their commissioning year, while Pampa del Sol Phase I was planned for 2028 and Cuna del Sol for 2029.
Outside of that portfolio, Empresa de Generación Eléctrica Coral is developing Coral, a 403.2 MW project in Moquegua, while Oryx Power is promoting Valladolid, a 400 MW project in Piura, the only project in the ranking located outside of Arequipa and Moquegua.
Energía Renovable La Joya is promoting Illa, with 396 MW; Kallpa Generación is focusing on Sunny III, with 370 MW, and Ocoña, with 335 MW; and Hidroeléctrica Sierra Nevada is developing Las Joyas, with 352 MW.
The list is completed by RDS Solar, in charge of Ruta del Sol, with 323.1 MW; AQP Energías Renovables, with Arequipa I, with 300.6 MW; CSF Continua Misti, with a park of 300 MW; and Generadora Renovable de Moquegua, with another plant of equal capacity.
Finally, Ecorer is promoting Solimana, with 257 MW, and Empresa de Generación Eléctrica Yuramayo is developing Yuramayo, with 255.2 MW.
Arequipa and Moquegua account for almost the entire portfolio

Arequipa brings together 11 projects for 4,215.8 MW , equivalent to 55.9% of the analyzed power. Sol de Verano III, Quyllur, Sumac Nina I, Illa, Sunny III, Las Joyas, Ocoña, Arequipa I, Continua Misti, Solimana and Yuramayo would be located there.
Moquegua concentrates eight projects for 2,927.1 MW , 38.8% of the total: Moquegua, Coral, Rubí V Phase I, Rubí V Phase II, Pampa del Sol Phase I, Cuna del Sol, Ruta del Sol and Generadora Renovable Moquegua.
Between these two regions , 19 of the 20 parks and 7,142.9 MW are located, representing 94.7% of the selected capacity. Valladolid, with 400 MW in Piura, is the only exception.
The concentration is also evident at the connection points. San José, Ocoña, and Montalvo serve as the main axes of the expansion , along with Ilo 3 and the future Hub San José, Quyllur, and Piura Nueva substations.
Bifacial modules, trackers and 500 kV networks
The technical specifications show that the new solar parks will tend to use bifacial monocrystalline modules , capable of capturing radiation on both their front and back faces. This technology allows for harnessing the light reflected off the ground and increasing the plants' energy production.
The use of single-axis solar trackers , which adjust the orientation of the panels throughout the day, is also becoming more widespread. Compared to fixed structures, these systems improve performance, although they incorporate mechanical components and require more maintenance.
The plants are usually organized using internal 33 kV collector networks , transformer centers distributed on the premises and step-up substations to deliver the energy to the system.
Illa provides a reference point for scale: its design includes 744,016 modules, 416 inverters, and 52 transformer substations . The plant will use bifacial monocrystalline panels and single-row trackers.
Due to the size of the projects, a significant portion are planned to connect to 500 kV . This group includes Moquegua, Sol de Verano III, Sumac Nina I, Sunny III, Ocoña, Arequipa I, and the developments associated with Montalvo.
Other parks will use 220 kV connections, such as Illa, Coral, Continua Misti, Yuramayo, and Generadora Renovable Moquegua. Las Joyas and Ruta del Sol will be integrated via dedicated transmission lines.
The predominance of very high voltage connections confirms that these are not plants intended solely for local supply. They are projects designed to inject large blocks of generation into the national grid , which will require coordination with transmission infrastructure and the availability of grid nodes.
The implementation of these developments will also be conditioned by the regulations of Law 32249 and by the call for new electricity supply tenders.
The sector expects that future processes will allow energy to be contracted through time blocks and offer long-term signals compatible with the profile of photovoltaic generation.
Regulatory issues and transmission needs will be part of the agenda at the upcoming Future Energy Summit Peru , to be held on September 28. The event will bring together authorities, generators, developers, investors, and suppliers involved in the country's energy transition.
The 20 projects identified demonstrate that Peru has the scale, solar resources, and a broad business portfolio. The next challenge will be to transform this technically assessed capacity into power plants with permits, contracts, financing, and grid connection infrastructure.
