Solar Star Funding LLC, a wholly owned subsidiary of MidAmerican Energy Holdings Co., announced it has completed a $1 billion offering of senior secured notes, the largest single project bond financing ever completed for a solar energy project. The offering of 5.375 percent notes will be used to fund the continued construction of Solar Star's 579-megawatt projects in Southern California. The co-located projects, Solar Star 1 and Solar Star 2, formerly known as the Antelope Valley Solar Projects, are the world's largest solar power developments under construction, the company said.
