Tell us about the unseen cost of wind and solar power, too

While we are on the topic of requesting public information for consumers of our monopoly electricity utility, could one of the sharp pencils at NV Energy or the Public Utility Commission estimate the ancillary costs of intermittent power?

Recently the Review-Journal asked for the contract price NV Energy proposes to pay several alternative energy producers for each kilowatt-hour of electricity it must buy to satisfy a legislative dictate that 25 percent of its power production must come from so-called “green” sources. On Tuesday the attorney general’s office filed paperwork arguing that the public’s right to and need for such information outweighs any vague argument about trade or proprietary secrets. The PUC is to decide soon whether you get to see what your future power bills will look like.

While geothermal and biomass can provide a fairly stable, round-the-clock source of power, wind turbines work only when the wind blows and solar photovoltaic panels only when the sun shines. When the wind doesn’t blow and the sun doesn’t shine, the power company must crank up some other generator, usually a perfectly good coal- or natural gas-fired generator that was sitting idle while those carbon-free turbines were momentarily working.

What is the pass-along-to-consumers capital cost of maintaining generation capacity that is used only as needed? What is the cost in manpower and high-tech equipment to maintain a balanced power load on the grid? What are the capital and operating costs of all those additional power lines to bring green energy to the grid?

Just for the record: How much would have each of the kilowatt-hours from those proposed-but-moth-balled coal-fired plants near Ely have cost ratepayers?

How many Americans died to produce the last kilowatt of solar power? How many American taxpayer dollars were spent sending American troops to far away places to fight for our "right" to travel the Middle Eastern sea lanes? Add that to the cost of gasoline. Or maybe you wanna talk coal eh Tom? Ok, how many billions of gallons of coal slurry is Nevada subject to have flooding over this state when it produces energy through wind power or solar power? Ask all those good citizens of Tennessee and Kentucky how great it is to have those billions of gallons polluting their drinking water with arsenic and benzene after the last greatest environmental disaster. Add that to the cost of all that "cheap" power. Or, would you rather that the Stephens Group and their "associates" at this newspaper NOT?

Coal doesn't cost 2 c/kWh, oil doesn't cost 5, and solar doesn't cost 35. Coal has 2 c more coal transport cost, 2 cents capital cost, and 2 cents emissions controls (plus the 2 c/kWh fuel cost, which is rising) - 8 c/kWh. Oil at $3/gallon as gasoline is 36 c/kWh driving your car (including losses in the engine). Natural gas is about 10 c/kWh. PV at $3/W in the Southwest is 15 c/kWh; and 22 c/kWh in NYC for the same system. A small rooftop system at $5/W in NYC is 35 c/kWh. There is no single price for PV since it obviously varies by system size and sunlight. PV prices have dropped 40% in the last 2 years and have a consistent track record of dropping 20% for every doubling in production (true since 1975).

Clicking through that figure shows those numbers to be from 2007. Isn't it great how fast PV has dropped in cost, from the $9000/kW in that figure (2007) to $3000/kW today!

Now do your readers want to be on the wrong side of this trend?

hmmm, could have used a bit more information about the hidden costs of coal and oil to start.

here's the definitive article on it

I used to work for the government and was in charge of our portion of the western grid (Bonneville Power Administration; Pacific Northwest. We also supplied some of Las Vegas' power).

Solar; wind and hydro electric are considered Base Load and they're 'on line' whenever they can be because they're the cheapest per KWH (regardless of your incorrect graphic). As the system peaks; the cheapest power is ramped up. Occasionally this is contracted purchased power (the very thing that doomed the crooked ENRON company).

By the way; electric utilities are not monopolies because they're control by the PUC and federal regulations.

So, Ken from the GW Solar Institute, are you slated to get some of the Nev Power contracts? Is Solar, and Wind capable of standing on their own, or are massive government subsidies needed to support you?

Great work if you can get taxpayer money to produce an inferior product, at a higher cost, and force the populace to pay. Corn for fuel comes to mind.

The sticky point are those unintended consequences, aren't they?

By the way, who does the PUC answer to? And isn't it conveniently confusing to have over 100,000 pages of federal regulation?

So. Mr. Mitchell, it seems you should have titled your story, "Tell us about the unseen BENEFITS of solar and wind power."
