- Financing summary: In December 2011, SMUD sold the nearly completed 128 MW Solano Wind Phase 3 to Citigroup for $288 million. The structure gave Citigroup the benefits available to a tax-paying renewable-energy owner, while SMUD purchased all Phase 3 output under a power purchase agreement and held repurchase options at the sixth, eighth, or fifteenth anniversary of commercial operation. SMUD expected the transaction to save customers $60 million to $70 million over six years.

## Data quality

- The 2011 transaction applied to Solano Wind Phase 3 rather than the entire multi-phase project; SMUD continued to purchase all Phase 3 output and later repurchased the plant. Capacity figures are scope-specific: Phase 3 is documented at 128 MW, Solano 4 at 85.5 MW, and SMUD reports the combined post-Solano 4 project at approximately 300 MW.
