The US installed a record 2.3GW of utility-scale solar in 2013, according to analyst firm SNL Energy.

The figure tops the 1.7GW set in 2012, thanks largely to a fourth quarter that saw more than 1.141GW of large-scale solar completed. Q4 2013 became the most active quarter beating Q4 2012’s 740MW.

The data includes concentrated solar power and PV.

The largest individual project that came online was Abengoa’s 250MW CSP Solar Generating Station in Arizona.

Seven of the ten largest projects were in California including the 139MW Campo Verde project and two phases of the California Valley Solar Ranch that came online totalling 181MW.

Utility-scale projects have begun dominating US solar installation figures with 80% of new capacity now covered y large projects, according to NPD Solarbuzz.

Michael Barker, an analyst with NPD Solarbuzz estimates that the top ten US states have a potential PV project pipeline of 40GW.
