Greetings,
In case you haven't seen them, I suggest looking
over:
This article in the Economist (7/26/14):
"Sun, wind and drain: Wind and solar power are even more expensive than is commonly thought"
And the Study/Report, "Net Benefits of Low and No-Carbons
Electricity Technologies," by Charles Frank leading to the
article:*
The study take a different approach from the all
too common and flawed LCOE type comparison by seeking to quantify costs of "net
benefits" of electricity from wind, solar, hydro, nuclear and gas (mostly
combined cycle). The "benefits" it compares
include:
. "Avoided CO2
Emissions"
. "Avoided energy
cost"
. "Avoided Capacity
Cost"
The favorable aspects of the study are (a) it's
far more comprehensive in the factors that are considered in most of the studies
that get attention, (b) it seems to be much more carefully done than most,
and (c) it candidly admits the dozens of assumptions and the sources of actual
and estimated data that underlie the analyses.
On the other hand:
1. It's findings need to be evaluated in
terms of your assessment:
a. The value
of the "benefits" (e.g., CO2 reduction) that are used to compare
costs,
b. The validity
of the assumptions and underlying data (much from EIA and much of which is also
based on estimates and assumptions).
2. Whether, while comprehensive, it leaves
out cost considerations that may be important;
e.g.:
a. Transmission
costs (which tend to be higher for wind),
b. Certain
subsidies which don't appear to be considered (e.g., federal nuclear
accident insurance; loan guarantees that reduce costs of capital for
certain types of plants; other subsidies & tax breaks that lure capital
to projects that would otherwise incur higher costs of capital regulatory
subsidies such as RPS that create artificial
markets;)
c Decommissioning
costs (not sure these are covered).
(As you might guess, I remain skeptical of
estimates and assumptions about useful life, production during useful
life, O&M costs of newer technologies), and/or decommissioning costs of
newer technologies.)
If you get time to review the report, I'd
appreciate hearing your views.

*The article also cites
Paul Joskow's 2011 article that affirmed what many of us had been contending for
several years earlier; i.e., that one must consider the true value of
the electricity, not just the cost of producing
it.
