Zelestra Delivers 57-MW Solar Power to Tesla in Spain

• Zelestra powers Spain: full operation at three Castile-La Mancha solar farms (57 MWac), supplying Tesla via a 2025 PPA—while scaling with 1.2 GW contracted from a 6.8 GW pipeline.

Zelestra said it has reached full commercial operation at three Spanish solar farms—Brazatortas I, II and IV—in the Castile-La Mancha region. Combined capacity is 57 MWac, and the company built the plants through its in-house EPC team.

The projects will supply about 130 GWh of electricity annually to Tesla under a power purchase agreement signed in early 2025. Zelestra added that it is also working on expanding in Spain, with 1.2 GW of contracted renewables projects out of a 6.8-GW pipeline covering solar, battery storage and wind.

How does Zelestra’s 57 MWac Spanish solar launch for Tesla expand Spain’s renewables?

• Adds new utility-scale solar generation in a major renewable region (Castile–La Mancha), increasing Spain’s near-term clean power supply.
  
• Raises overall grid decarbonization by displacing fossil-based electricity and improving the renewables share in Spain’s generation mix.
  
• Supports corporate renewable demand: the output contracted to Tesla helps scale clean-energy procurement by large industrial and mobility buyers.
  
• Provides predictable, long-term generation via the power purchase agreement, supporting investment confidence and planning across Spain’s power sector.
  
• Delivers substantial annual production (around 130 GWh/year), contributing meaningful additional baseload-like generation during daylight hours.
  
• Strengthens Spain’s transition targets by bringing new capacity online as the country continues to expand solar, storage and wind.
  
• Enhances supply diversity within the renewable portfolio by adding more grid-connected solar assets alongside other technologies.
  
• Demonstrates domestic project execution capacity: Zelestra building the plants through its in-house EPC team can help streamline delivery and capacity additions.
  
• Signals continued pipeline momentum: contracted projects of 1.2 GW out of a 6.8-GW pipeline indicates further near- to mid-term additions beyond the initial 57 MWac launch.
  
• Broadens future renewable pathways beyond solar alone, since the pipeline covers solar plus battery storage and wind—helping Spain improve reliability and flexibility as renewables grow.
• Reinforces local economic and industrial activity in the region through construction and ongoing operations of multiple plants.
