From there, they examined how the cutoff voltage used for switching flow paths, external resistance and salt concentrations influenced peak and
average power production.

«Gross Revenues» means the total monies received by Grantee from a utility company or other
power purchaser (provided, however, that if electricity is sold to a subsidiary or affiliate of Grantee, then, and only then, the gross receipts from the sale of electricity under such contract shall be calculated using a sale of not less than the arithmetical
average of the prices quoted by market sources of information, which information may be based upon the price paid by any purchaser or purchasers, including Grantee or any subsidiary or affiliate of Grantee, for electricity produced in the Iowa region of the Midwest Independent System Operator («MISO») from operation of wind turbines during the calendar year immediate!y preceding the year in which such electricity
production from the Wind Energy Project occurs, taking into account the aggregate terms associated with such transaction) derived from the sale of electric energy and capacity produced and sold from the WTG's installed on the Premises, net of proportional energy losses associated with the
power collection system or utility interconnection.
Scott Mackenzie, Natural
Power's Director of Asset Management, described his company's «total asset management» database and tools that define optimum performance, and Glen Benson, AWS Truepower's Manager of Performance Analysis, explained his company's new statistical tools (
average wind speed to energy
production ratio, downtime to
average energy
production ratio).
Further, the capacity factors quoted range from 11 % to 27 %,
averaging under 20 %, meaning these are actually even smaller, in terms of
power production.
First Solar's annual
production capacity will double in 2009 to more than 1 gigawatt, the equivalent of an
average - sized nuclear
power plant.
Wind turbine project installed cost: $ 2,000 / kW Typical mechanical life of a wind turbine: 20 years Hours per year: 8,760
Average availability of wind
power: 24 % Market value of 1 kWh of electricity at
production site: $ 0.07 Value of total electricity produced during wind turbine life: 20 x 8,760 x 0.24 x $ 0.07 = $ 2,943 / kW installed As you can see the payback on wind turbine projects is iffy even with no maintenance and operating costs included in the equation.
For comparison here is the same equation for a coal - fired
power plant: Coal
power project installed cost: $ 2,500 / kW (High end number — Some coal fired plants are built for $ 1,500 / kW) Typical life of a coal fired plant: 30 years Hours per year: 8,760
Average availability of coal - fired
power plant: 88 % Total electricity
production during plant life: 231,000 kWh / kW installed Value of electricity produced: $ 16,188 / kW installed Lifetime Cost of fuel = 231,000 x $ 0.006 = $ 1,388 / kW installed Net Value of total electricity produced during plant life: $ 14,800 / kW installed.
After mentioning that capacity factor is (correctly) relevant to comparisons, you then proceed on the basis of nameplate
power ratings instead of annualised
power production in TWh or time -
averaged generating capacity after multiplication by the capacity factor.
And the EREC / Greenpeace's Energy [R] evolution» 24/7» report concluded that «during the last 30 years, the potential
power production from wind during winter time throughout Europe in the Energy [R] evolution scenario would have only dropped below 50GW 0.4 % of the time, equivalent to once a year if the
average duration of the event is 12 hours».

For the 2020 Medium scenario the countries studied showed an
average annual wind capacity factor of 23 — 25 %, rising to 30 — 40 %, when considering
power production during the 100 highest peak load situations — in almost all the cases studied, it was found that wind generation produces more than
average during peak load hours.
The cost of wind energy has fallen 65.5 percent since 2009 according to the DOE report, which also says the U.S. is the global leader in total wind energy
production, with enough to
power the equivalent of 18 million
