Zelestra has begun full commercial operations at the 300 MW San Martín solar plant in La Joya, Arequipa – now the largest solar facility in Peru.
Completed in under 18 months by Zelestra’s in-house engineering, procurement, and construction team, the plant features 450,000 solar modules and is expected to generate 830 GWh of renewable energy annually.
This output is enough to supply electricity to over 440,000 homes.
The project, which supported 900 jobs at peak construction, is anticipated to reduce carbon emissions by more than 166,000 tonnes each year.
Power generated at the site will be delivered to Kallpa Generación under a long-term power purchase agreement, contributing to Peru’s efforts to diversify its energy mix.
Leo Moreno, CEO of Zelestra, said: “The successful delivery of San Martín reinforces our commitment to a customer-first approach. We are proud to see the most ambitious solar project in Peru now fully operational and look forward to a long-term partnership with Kallpa.”
Zelestra currently has a development pipeline of 7 GW in solar and battery energy storage projects across Latin America, including 1.7 GW already contracted in Peru, Chile, and Colombia.
The company was recently named among the world’s top 10 corporate clean energy sellers by BloombergNEF and ranked second across Europe, the Middle East, and Asia.
