In late June, MidAmerican Energy completed  a $1 billion bond offering - the largest single bond financing for a solar project to date.Interest on the Series A note will be paid starting in June 2016 at 5.375%; the notes mature in June 2035.

The funds will be used to complete the build-out of the world's largest solar plant, the 579 megawatt (MW) Solar Star Project, previously called Antelope Valley. It consists of two co-located but separate projects, Solar Star 1 and Solar Star 2, in southern California's Antelope Valley.MidAmerican Solar bought the project from SunPower for $2 billion in January, and SunPower is developing it using its own panels. The project  will begin to provide power to 400,000 homes in 2015.This is MidAmerican's third successful bond offering in solar, all of which have been oversubscribed.Since it began acquiring renewable energy projects last year, MidAmerican Renewables has quickly grown to an 1830 megawatt (MW) portfolio in wind, geothermal, solar and hydro.
