13. FINANCIAL EVALUATION (BID WINDOW 1) 13

14. Introduction Majority of bids to a generally high standard; No bidder submitted a fully compliant Part B submission; Significant number of failures related to non-material omissions and inconsistencies perhaps reflecting tight timeframe for bid preparation; 14

15. Financial Evaluation Key areas of shortcoming included: Letters of support not provided by parent company &/or funders; Rationale and quantum of success fees not fully described; Limited information on hedging strategies; Incomplete financial accounts for equity participants Calculation of partial/fully indexed tariffs not done comprehensively. 15

16. Financial evaluation results Results post-clarification: Solar PVWindCSPHydroTotal Pass (MW)68270115001533 No. Projects21102033 Fail (MW)35723304594 No. Projects1630120 16

17. Financial Analysis – Tariffs Majority of bidders have priced at or just below the applicable technology price cap; Similarly most bidders have shown a strong preference for a fully indexed tariff; This may reflect bidder expectation that Round 1 would be undersubscribed. 17
