BrightSource finalized $1.6bn in loans guaranteed by the US Department of Energy.
The project which is currently under construction, has also secured investments of $168m from Google and $300m from NRG Solar.
The project which is being delivered by BrightSource’s engineering partner, Bechtel, will be complete in 2013.
The Ivanpah project is a 392 gross-megawatt solar power facility consisting of three separate solar thermal power plants.
On completition, the project will produce enough clean energy to power 140,000 homes.
BrightSource has contracted with PG&E and SCE to deliver approximately 2,600 megawatts of electric power.
Pacific Gas and Electric (PG&E) will purchase approximately two-thirds of the power generated at Ivanpah and Southern California Edison (SCE) will purchase approximately one-third.
The project secured its state permits from the California Energy Commission and federal permits from the U.S. Department of the Interior’s Bureau of Land Management last year.
