Comparison of Coal Power to PV

I ran across a discussion about how many coal power plants are equivalent to 10GW of PV.  I ran the numbers and below have posted the results.  10GW of PV is equivalent to 5 coal power plants.  Many assume that coal plants average 1GW.  But they actually average about 0.5GW.  They also have surprisingly low capacity factor of under 70%.  This means that when adjusted to 100% equivalent the average coal plant is about 376 MW or .376GW.

I was surprised to learn that in the Southwest, solar power plants are seeing capacity factors up around 25%.
