Ausra has reportedly raised $24.5 million in venture debt led by Khosla Ventures and Kleiner, Perkins, Caufield, & Byers.

According to a regulatory filing reported by Pehub.com, Ausra has finalised its Series C funding. This latest round of funding included a new backer, private equity firm KERN Partners, as well as existing investors Khosla Ventures and Kleiner Perkins.

The company, which develops and deploys utility-scale solar technologies, has already shared that it is now growing beyond its original Australian pilot project and is open for business to supply clean, cost-effective solar power and process steam for customers and communities at the largest scale.

Ausra currently has solar steam production fields and power plants in construction and development in Australia and the US, and has recently opened the reflector production line of its first North American manufacturing and distribution center in Las Vegas.

Last month, Ausra had officially opened Ausra Pty Limited in Australia. The company, headquartered in Palo Alto, California, will build upon Ausra's first-generation technology developed in New South Wales and deploy it on a large-scale basis, providing electricity and steam for utilities and industrial customers.

Late last year, Ausra and California utility Pacific Gas and Electric Company had shared plans for a power purchase agreement for a 177-megawatt solar thermal power plant to be built in central California. The power plant will generate enough electricity to power more than 120,000 homes.
