Aiken Trackers

Aiken trackers produced 112,482 kWh

Based on Aiken energy models

Renewable energy production is 28.8% of total energy use

2013 CEF Moving Toward Net-Zero at Aiken • Aiken Center and classes continue to teach about sustainable building practices • Net-zero building achievable goal for UVM and CEF • Fits CEF mission to finance clean energy projects • Aiken Center designed for Net-zero

2013 CEF 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

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
