Draft Budget (17-20 tracker units) • Power Purchase Agreement (PPA) • $0 upfront costs • 10% power cost savings for up to 25 years
Moving Toward Net-Zero at Aiken
Draft Budget (17-20 tracker units) •
Power Purchase Agreement (PPA) • $0 upfront costs • 10% power cost savings for up to 25 years
• At end of year 6 and every year after that • Purchase system for Fair Market Value
• Outright cost ≈ $400,000 • Cost after 6 years ≈ $200,000 • After purchase CEF gets >$13,000/yr power • After purchase CEF get >$6,000/yr GMP rebate (+ 0.06/kWh) • <11.1 year payback period of CEF investment 11
