- Financing summary: Alta Projects II-V closed approximately $1.2 billion of construction financing in July 2010 for 570 MW in aggregate. The package included approximately $580 million of pass-through certificates due 2035, a $499 million construction bridge loan, and $127 million of ancillary credit facilities. The permanent structure was a leveraged lease under which Citibank committed to purchase the projects at commercial operation and lease them back to Terra-Gen; Citibank, Barclays Capital, and Credit Suisse were identified as financing parties. Separately, on August 12, 2014, NRG Yield paid $870 million for the broader 947 MW Alta facility and assumed $1.6 billion of non-recourse project financings; that was portfolio acquisition consideration, not Alta V-specific project financing. — Alta Wind Energy Center (AWEC), California · confidence: medium
