• Novel business model
• Ownership, Desig, construction, operation & maintenance by heat
supplier.
• PESolar take care of all risks: operational, technical & solar radiation.
• Codelco only pays for the energy used in the process (with a ToP)
with interesting savings on Diesel alternative
Pampa Elvira Solar SpA:
Thermal Power Purchase Agreement:
• Agreement on minimum monthly amount of solar energy delivered.
• We operate and maintain heaters as backup as well as Heat
Exchangers
• 24/7 heat supply.
• Covenants on heat supply quality (Electrolyte Temperature) and
safety.
• Contract length: 10 years.
• Stable energy tariff US$/MWh + Fixed charge heaters O&M.
