Trump Paris clexit heralds avalanche of fake news

Heads will explode as the GreenLeft media search for angles to abuse Trump. I noticed this classic climate scaremongering bulltish story of a type that has polluted our news for decades. Sea level rise may force coastal nesting birds to extinction, ANU researcher says 2 June 2017 So coastal nesting birds have survived tens of millions of years of evolution including several ice ages where sea levels would have risen and fallen over 100m – but they are heading for extinction now. You know it makes sense.

AEMO forecasts large cut in the electricity spot price on 1st May

Checkout AEMO Price and Demand charts. I kept screen shots – NSW, Qld, Vic, SA all showing a greater than halving of the spot price as the 1st of May starts. But Tasmania scores a price hike that more than doubles. We will see what AEMO spot prices do in May. For snapshot of all States generation by type there is NemWatch.

Why is AEMO electricity price for Tasmania rocketing?

I have been watching my 5 States chart and the rise in AEMO wholesale price for Tasmania since Feb puzzles me. I thought their relatively large hydro resource might have insulated Tassie from the more erratic prices interstate. Hydro Tasmania is State Govt owned and is swamped with debt.

Most Ivanpah power comes from natural gas

I had not heard much about the Ivanpah Solar Power Facility for a while – no wonder – Recall we were told gas would be used to warm the boilers on cold Mohave Desert mornings. But when you convert the ever increasing natural gas usage to MWhrs – Ivanpah electricity production is mostly from natural gas.

First day post Hazelwood – Tassie Hydro props up Eastern electricity grid

Comments starting with Qld (grid “strongman” now) and during an eastern wind drought. Generation by Nemwatch – Price and Demand from AEMO. For bigger Nemwatch chart

QLD demand 6,042MW with generation 6,959MW running a modest surplus in view all grids need some spinning reserve.
NSW demand 8,306MW with generation 7,686MW running a surprising deficit. Must be maxing imports from Qld.
Vic demand 5,373MW with generation 5,328MW small deficit should have spinning reserve. I have never seen Vic in deficit in a year or more watching.
SA demand 1,525MW with generation 1,323MW running a deficit – must be importing from Vic.
Tas demand 1,277MW with generation 1,902MW running a big surplus – Basslink must be humming at near max 600MW feeding power to SA, NSW and Vic.
For months Vic has been the lynchpin State exporting as required to NSW, SA and Tas. Verily our politicians have wrought harm to our electricity system.

Labor abandons 50% by 2030 renewables target

There were signs from Perth a week ago – then the Illawarra Mercury had a crack at it – then on ABC TV The Drum Episode 15 last night host Ellen Fanning introduced her first segment with “and Labor’s backdown on its renewable energy target”.

Keep Hazelwood open

Hazelwood 1,600MW of electricity generation is due to close at end of March. This must further stress our already strained power supplies and rack up prices further. People concerned that this would weaken our electricity grid should email politicians asking that Hazelwood be kept open. I will be emailing the PM, Treasurer and several other members of the Commonwealth Parliament. For information email to –
Keep.Hazelwood.Open (the you know what symbol) engineer.com
Terry McCrann had a good article – Keep Hazelwood power station open through takeover

NSW is usually an importer of electricity – interesting that generation for our largest State is propped up by imports from both Qld and Victoria. NSW is an Importer of Electricity – my series of Nemwatch charts annotated with simultaneous demand & price data from AEMO. There will be more data to present on the subject.
The upshot is – Victoria is the Lynchpin State of our grid in terms of electricity generation. Another reason to “Keep Hazelwood open”
