Summary of Wind Power Generation For 2007
Electricity generation via wind turbines is uncontrolled, in that the wind blows or not irrespective of the timing of the demand for electricity. Measurements of the generation over half-hourly intervals are supplied to the Electricity Commission. There are isolated wind turbines at Brooklyn and Gebbie's Pass. At the Te Rere Hau wind farm there are five 500KW wind turbines, however the transmission line to the rest of the electricity grid is limited to one megawatt.
In the charts below, the horizontal layering shows the effect of a single turbine (or a small number of turbines) running at their maximum output:
- Te Rere Hau
For Te Rere Hau, however, the graph suggests that this maximum setting is about 200KW, not the nominated 500KW.
- Hau Nui
The Hau Nui wind farm has an intermediate capacity.
- Tararua
While south of the Manawatu Gorge the Tararua wind farms operate almost in synchrony. Construction of the Tararua III wind farm began in early 2007.
- TeApiti
North of the Manawatu Gorge is the TeApiti wind farms, while in Southland the White Hill wind farm began operation.
- ClydeNewPlymouth
By contrast, the Clyde hydro power station (for example) has its generation timed to suit demand, likewise the New Plymouth thermal power station - which was deactivated in October 2007, until the resulting power shortages in 2008 encouraged its partial reactivation.
- Combined
Combining all the wind generation shows that the total production was uneven over the year due to variations in capacity.

Famous quotes containing the words summary, wind, power and/or generation:
“I have simplified my politics into an utter detestation of all existing governments; and, as it is the shortest and most agreeable and summary feeling imaginable, the first moment of an universal republic would convert me into an advocate for single and uncontradicted despotism. The fact is, riches are power, and poverty is slavery all over the earth, and one sort of establishment is no better, nor worse, for a people than another.”
—George Gordon Noel Byron (1788–1824)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“I hate this shallow Americanism which hopes to get rich by credit, to get knowledge by raps on midnight tables, to learn the economy of the mind by phrenology, or skill without study, or mastery without apprenticeship, or the sale of goods through pretending that they sell, or power through making believe you are powerful, or through a packed jury or caucus, bribery and “repeating” votes, or wealth by fraud.”
—Ralph Waldo Emerson (1803–1882)
“Through centuries he lived in poverty.
God only was his only elegance.
Then generation by generation he grew
Stronger and freer, a little better off.
He lived each life because, if it was bad,
He said a good life would be possible.”
—Wallace Stevens (1879–1955)
