The MidAmerican deal comes after Terra-Gen Power said it had closed a $650 million financing deal for the 168MW Alta Wind VII and 132MW Alta Wind IX projects.
The Alta VII and IX financings include construction and seven-year term loans, bridge loans to the ITC cash grants from the US Department of Treasury, and ancillary credit facilities.
