Why Solar for Santa Rita Jail?
1.2 mW Santa Rita Integrated Solar Power Project
Available Roof space
Lots of Sunshine
Large Electric Load
Project FinancesProject FinancesCombined with other energy efficiencies with shorter paybacks
Chilled water retrofitCool roof
Met internal rate of return –10% hurdle rate
Half cost from state and utility rebates
Low-interest Loan from California Energy Commission
Remainder From Energy Fund and Major Maintenance Fund
