Closer Look of World’s Largest Solar PV Project, Agua Caliente Solar Project, & Call For Consistent Standard !


Dear Friends & Visitors/Viewers/Readers,

(Please click on red link below)

As I’ve promised you, let’s take a look at the largest solar PV project, Agua Caliente Solar Project, currently under construction in Yuma County, AZ, having achieved a peak generating capacity of 250 MW connected to the electrical grid and will have a generating capacity of 397 MW (DC) or the equivalent of 310-320- MW (AC) when completed.

Recalling from our previous post of October 17, 2012, there was an issue/discrepancy between the maximum generating capacity listed in wikipedia (397 MW in wikipedia vs. many other sources’ 290 MW).  After further digging/investigation, I’ve discovered two things:

1.  In PV Tech Oct. 14, 2011 issue,  please note the quote below:

The original nameplate for the entire plant was 290MW (AC), but Christian said that a 12th block is in the engineering stage and should start early construction soon.

The additional set of arrays would add another 20–30MW (AC), bringing the total to 310–320MW (AC), or about 397MW (DC) after conversion – an amount estimated

to require in the neighborhood of 5.2 million PV panels.

2. Upon careful overview of multiple journals/articles,  I’ve come to realize that the industry as a whole needs a much more consistent standard (AC or DC) for basis of comparison.  Case in point, above, different power plants may provide information/data in AC or DC (AC and DC data may differ approximately 15%), presenting much confusion for the consumers and readers alike.  At this point, I’d like to share an article that would help to shed more light on this subject: AC-DC conundrum: Latest PV power-plant  ratings follies put focus on reporting inconsistency (update).   Please do not get too alarmed by this, for this, to me, is part of the growing pain;a sign that the solar industry is still young enough that it needs to work out some of its kinks;a sign  indicating that solar industry still has much room to grow.  It simply needs a unified voice.  So perhaps in future Solar Power (Generation, International, etc.) conventions/conferences, there should be one more topic added to the list of discussions: AC or DC, That Is The Question ?!
