Photovoltaic Energy San Juan-Cañada Honda The intermittency index or capacity factor To understand better, I prefer the first baptism, compared to conventional capacity factor. The reason is that the name suggests in itself the cause. Imagine a 2.1 Megawatt wind turbine costing u $ s 7 million (Valle de Arauco). The capacity factor is 29.80% for the area but the same aircraft is in the wind farm Commodore Peter Moran of 56.88%, 52.83% in Puerto Deseado and Santiago del Estero 8.77. % What is the reason? Very simple.
blink rates provide for just that: in each area of \u200b\u200bthe aforesaid, the CREE (Centre for Wind Energy Regional) has proceeded to place an anemometer to measure charge for a long time always greater than one year, the different speeds and wind direction as well as energy simulated for all cases, the presence of the same turbine. The work is commendable and deserves the recognition of all who have been involved in this field for over thirty years. I recommend visit www.sigeolico.com.ar What does Santiago 8.77 56.88 Comodoro respect? Just that the 8760 hours is a year we can expect to Santiago are only
768 (0.0877. 8760) those with enough wind energy to hope that the 2, 1 Megawatt turbine are fully exploited. Recall that power is the power of time and is measured in megawatt hours annually so it can be expected to Santiago del Estero, 2.1 MW x 768 hours = 1612 Megawatt hours. In contrast, with the same 2.1 MW wind turbine, in Peter Moran and Rada Tilly Comodoro Rivadavia, the account shows,
0.5688. 8760 hours. Mw = 10,463 Mw 2.1 hour / year That means 6.5 times the 1612 production of Santiago, whose winds have a flashing 6.5 times higher than those of Patagonia, which Santiago del Estero should be completely discarded for investments windmills.
Unless officials are aware of the situation and listen without all the bells superb, especially those in which only seeks the truth no interest whatsoever. In conclusion, then, the rate of blinking, capacity factor or utilization rate is the coefficient that reflects the inconsistency of natural energies, despite the redundancy, are subject to intermittent.
Although we have dealt with the apology for the repetition, say that the flashing can be random or circumstantial case wind or even systematic, such as solar, in which the day and night are the best example. Let
parameters intermittency coefficient of solar radiation that is precisely the purpose of this note. Just as the CREE has done in very little time to study and the collection already mentioned, for more than three decades Asad has done the same with the daily solar radiation for different parts of the country giving the values \u200b\u200bexpressed in Kw hours per square meter surface for winter and summer solstices.
Consider the meaning to refer to an index of intermittency. As in the case of wind, if it were constant and appropriate intensity (40 Km / h) Annual Energy's 2.1 MW would be multiplied by the 8760 hours per year.
In the case of solar radiation that sends power Phoebus called the solar constant is 1.3 kW per square meter but finally to round up the floor is 1 Kw. But the Earth's rotation is responsible for allocating the best way spherical surface, for example, of the 24 daily kwhora in Necochea received by June, 1.88 Kwhora per day per square meter of surface when in San Juan are 3.06 and 8.2 for December. Seen as the coefficient of intermittence, serious 0.1275 and 0.34 for the summer, that comes with the same concept dividing the actual radiation measured by ASAD, absolutely indisputable, for the 24 theoretical Kwhora per day would generate the cells if they work 24 hours, and as a comparison against a hydraulic turbine or power plants that are uninterrupted.
In other words, the ratio used to compare economically to different investment options, separating the real from the apparent. Example: each of 2.1 MW wind turbine costs $ 7 million, apparent reversal, since the real purpose of comparison with one thermoelectric are 7 million divided by the coefficient of intermittence that Arauco is 0.293 to 0.56 and for Santiago Comodoro 0.087.

"offer" at a discount by the nature of 84% compared to the real Santiago. (1 to 0.087 / 0.56) Similarly, the apparent cost of the investment PV grid connection "provided in Cañada Honda is u $ s / Kw 6250 and if we separate the real ones for winter and summer would be u $ s. 49,019 and 18,832.
For the journalist who wrote the note in the supplement Cash 27/03/1911 Page 12 of mentioning a 600% more expensive than thermal him adviser to advise change since the 20 Mgwatios correspond to the installed power and not the generation, ie without taking into account the intermittency
rates. Suppose we take the average of 3.02 and 8.2 (5.61). The real investment is U.S. $ s / kW to 26,789 against the $ s / kW thermal Barragán 1160 are 2309% more and not 600% as mentioned in the note. Lacks
Mr Callejas moral authority to criticize the current government about investing in nuclear energy when he was responsible for the stagnation participant for 20 years Atucha II (Alfonsin 1983/1989) and costs the same as four-fold today normal of any investment in the world.
Let's see if these differences justify, as it says the note, "the energy produced at minimal cost" Annual Costs

Ultimately, the problem is getting with the initial $ 119.6 million but also will add an annual loss of 8,085,000 U.S. $ s with which they could buy each year 1.5 additional gas turbines after 20 years depreciation assumptions mean 53 in total,
Let Adding ... Like the wind energy PV Grid Connection line coupled automatically entered in the Public Service when the sun and radiation screens accuse raising its voltage .
the same way they do the sixty wind turbines installed in our territory as the wind exceeds 3 to 4 m / sec., Unlike other alternatives where approval is required CAMMESA, the agency that controls the input sequence based on economic optimization. Hydroelectric stations, nuclear power plants constitute what is called the power base. Conceptually, as we have explained, the intermittent input line of a wind power plant, to maintain constant consumption, requires a reduction in the production of a basic lysine in the same proportion. In conclusion, partly out of a Francis turbine service Piedra del Aguila which is the spot price of replacement MEM and enters a power line extremely expensive, about 3 to 4 times higher. More than one reader advocate of the system can tell me that the power ratio between the base and photovoltaic San Juan is negligible which is true but is it worth distort an entire control mechanism to blend and confuse ourselves, wasting time to clarify issues of a level and inconsequential importance, looking at the plants without seeing the forest?
Important Note: The choice of Santiago del Estero as a benchmark is not arbitrary. Internet access with only the reader can learn properly. We recommend to read the comparison of solar, wind and hydro power which belongs to the blog and that is itself eloquent.
Errata From Spain, a very good friend of John interfere to correct an inadvertent error crept into this note:
"If you you have an annual loss equivalent to amount of 1.5 gas turbine for 20 years, the total loss after that time are 30 turbines, but 3325, a figure that emerges from elevar1, 5 the exponent 20. (1.5
20 = 3325). Obviously, you will understand that only the state can handle this deficit, which makes it difficult to understand that point of view. Better do you think that what it loses one wins the other in which case you imagine that YOU ARE the other side and instead of spending U.S. $ S125 million in 20 MW photovoltaic invierteis 5.6 in a gas turbine of 4.6 MW equivalent I throw an annual result of 1.5 x 5.6. Reinvesting the surplus for 20 years you will have 3325 turbines, in addition to the original 119.4 million difference "
