The 2015 edition is now available.

Some highlights:

• They included a sensitivity analysis (!) along with their statistical findings. Applause!!

• Figure ES.2 shows the LCOE ranges for various renewable technologies – namely, the three categories of solar PV in the study (residential, commercial and large, ground-mounted) and the two categories of wind (onshore and offshore). It is immediately apparent that the ranges in costs are significantly larger than for baseload technologies. It is also notable that the costs across technologies are relatively in line with one another. While at the high end, the LCOE for renewable technologies remains well above those of baseload technologies, at the low-end costs are in line with – or even below – baseload technologies. Solar PV in particular has seen significant declines in cost since the previous study, though onshore wind remains the lowest cost renewable technology. The median values for these technologies are, for the most part, closer to the low end of the range, a reflection of the fact that this chart obscures significant regional variations in costs (in particular for solar PV). This is not surprising, because the cost of renewable technologies is determined in large part by local resource availability, which can vary significantly among countries or even within countries.
