Of the total under construction, 1.26 GW are CSP projects and 3.36 GW are PV projects.
The Solar Energy Industries Association (SEIA) has found 4.62 GW of solar photovoltaic (PV) and concentrating solar power (CSP) plants larger than 1 MW under construction in the United States, as of August 15th, 2012.
The association released this information in an update to its listing of U.S. utility-scale PV and CSP projects.
The SEIA found an additional 24.8 GW of utility-scale solar projects under development, as well as 2.08 GW of operational utility-scale PV and CSP.
Majority of plants under construction in California.At 3.48 GW, a large majority of the PV and CSP projects under construction are located in California.
Arizona came in second place, with 675 MW under construction, followed by Nevada at 156 MW.
Of the total under construction, 1.26 GW are CSP projects and 3.36 GW are PV projects. While CSP makes up 27% of utility-scale projects under construction in the nation, the proportion of utility-scale CSP projects under development is smaller at 19% of the total, or 4.77 GW.
The list does not count residential, commercial or other PV or CSP plants under 1 MW, noting that operational residential, commercial, non-profit and government PV and CSP plants total 3.15 GW.
