The Department of Energy's environmental review confirms Agua Caliente as "a 290 megawatt gross output photovoltaic solar power project" in Yuma County, Arizona, though it gives no specific construction or operational date to compare against the pin's stored 8 May 2014 date.
Power Technology states the "Agua Caliente Solar farm is a 290MW photovoltaic (PV) power project" whose second phase "was completed in April 2014", about a month before the pin's stored 8 May 2014 date, corroborating both the 290MW figure and the general completion timeframe.
