NZ Windfarms

If 4.5 windfarms per year is the answer, then it was a stupid question

Never mind the scenery, feel the Green

Germany has gone all out on its Energiewende (energy transition) project, leading the Eurozone by example in how to save the world with renewables. In spite of the huge amounts of cash spent on wind and solar the project has only resulted in higher electricity costs for consumers and no change at all in CO2 levels.

WUWT has a great analysis of why this does not work in Germany and points out the huge elephant in the room for Megan and her 4.5 windfarms per year proposal to ‘zero carbon’ New Zealand. The problem: Who are we going to export to? This post allows us to examine German power usage on January 7-9, 2016 to understand the problems caused by intermittent renewable power. Quote.


This graph begins at start of January 7, which is a Thursday. The load line (black) shows low power usage. The spot price (orange, right-hand scale) is 25?/Mwh. The blue line is the sum of wind and solar power, and the red line is how much power is being exported.

The day starts and the load increases as people head to work. The spot price rises to 42 ?/Mwh because the load is increasing. The wind picks up and the wind+solar line rises. It keeps rising throughout the day. As people go home and the work day ends, the spot price plummets to 12 ?/Mwh because there are too many producers of electricity. To cushion the system, more power is exported.

Wind Farms are Noise Pollution


Quite apart from junking up the landscape and polluting visually, wind farms also have been found to create excessive noise pollution:

Residents complaining the nearby Te Rere Hau Wind Farm is too noisy have been vindicated, with the Environment Court ruling the farm owner breached its resource consent.

Noise predictions supplied by NZ Windfarms were wrong.

In a potentially precedent-setting decision released yesterday, the court ruled the noise effects on residents were “considerably greater” than those predicted in the resource consent application.

This put the 97-turbine wind farm on the Tararua Range in breach of its resource consent to such an extent that Palmerston North City Council could now choose to review its noise consent conditions.

Bob Stewart lives on Pahiatua Track near the wind farm and said he was pleased the court had recognised residents’ concerns.

“What we were hit with in terms of noise was quite different to what the application said it would be,” Mr Stewart said.

“It’s vindicated the residents’ concerns. It’s some comfort to know we’re not just a bunch of complainers with no grounds [to complain on].”

Mr Stewart said the ruling had made it clear assessments of the effects on the environment produced by those wanting consent for wind farms “needed to be accurate”.

“Hopefully it will be a wake-up call to other applicants that have to get it correct.”

The city council gave NZ Windfarms resource consent for Te Rere Hau in 2005. An extension was later granted.

Since its construction the wind farm has been the source of hundreds of noise complaints by neighbouring residents. That led the council to ask the Environment Court last year whether Te Rere Hau was operating within its resource consent.
