'World's largest single-axis plant' complete


Spanish biotech company and solar developer Abengoa has completed construction of what it claims is the world’s largest single-axis solar plant.

The 206 MW Mount Signal Solar project, in the city of Calexico, in the south-east of California, features more than 3 million panels across its 801-hectare site and will supply power to the San Diego area.

In a press release issued by Seville-based Abengoa on Wednesday, the company – which supplied engineering, procurement and construction services on the project – claimed the 16 months taken to commission and construct the project was ‘a record.’

Abengoa performed EPC on behalf of Silver Ridge Power, a joint venture between The AES Corp and Riverstone Holdings – formed to develop and operate solar plants and formerly known as AES Solar.

Tech giant Google announced in October it was investing $103 million in the Mount Signal project, which it described as a 265.7 MW scheme which would sell power to San Diego Gas & Electric under a PPA.
