  • Zelestra's 300-MW San Martin solar farm in Peru powers 440,000 homes, marking a renewable milestone with 450,000 modules and 830 GWh annual output.

Spanish renewables company Zelestra has launched the 300-MWdc San Martin solar farm in Peru, now fully operational and supplying power to Kallpa Generacion. Located in Arequipa's La Joya district, it is the largest solar facility in Peru, featuring 450,000 modules and an annual output of 830 GWh, sufficient for over 440,000 homes. The project was completed in under 18 months.

The San Martin plant's power is contracted to Kallpa under a long-term PPA, supporting its renewable energy expansion. Zelestra's portfolio includes over 29 GW of carbon-free projects across 13 countries, with over 7 GW in Latin America, including Peru, Chile, and Colombia.

How does the San Martin solar farm impact Peru's renewable energy landscape?

  • Increased Renewable Capacity: The San Martin solar farm significantly boosts Peru's renewable energy capacity, contributing to the country's goal of increasing its share of renewable energy in the national grid.
  • Energy Independence: By generating 830 GWh annually, the solar farm reduces Peru's reliance on imported fossil fuels, enhancing energy security and independence.
  • Economic Growth: The project creates jobs and stimulates local economies, both during the construction phase and through ongoing operations and maintenance.
  • Environmental Benefits: The solar farm helps reduce carbon emissions, aligning with global efforts to combat climate change and supporting Peru's commitments under international environmental agreements.
  • Technological Advancement: The deployment of 450,000 solar modules showcases advancements in solar technology and sets a precedent for future renewable projects in the region.
  • Regional Influence: As the largest solar facility in Peru, the San Martin solar farm positions the country as a leader in renewable energy within Latin America, potentially influencing neighboring countries to pursue similar projects.
  • Long-term Energy Contracts: The power purchase agreement (PPA) with Kallpa Generacion ensures a stable and predictable revenue stream, encouraging further investment in renewable energy infrastructure.
  • Grid Stability: By diversifying the energy mix, the solar farm contributes to grid stability and resilience, reducing the risk of power shortages or outages.
  • Community Engagement: The project may include community engagement initiatives, promoting awareness and education about renewable energy benefits and sustainability practices.
