The Australian Greens – Election 2016

The Australian Federal Election has been called for the first weekend in July. Like all these political things, its bloody hard to escape. The big parties are making the usual noises, but could The Australian Greens sneak up on them with a solar-powered stick?

One Bloke’s Perspective

I’ve don’t consider myself politically active. No time for student politics when you’re drinking at University. No set opinions on voting, except maybe putting the hard line religious parties dead last on any ballot paper, if they dare to show up in my electorate. Separation of church and state!

A firm belief that politicians get paid too much. That’s a point on which I’ve had many arguments. Australian politicians are among the best paid in the world, and have some ridiculously good retirement benefits.

Look, I’m quite sure parts of being a Member of Parliament suck, but there are parts of every job that suck. For that kind of money ($195K base + extras) I could put up with some crap – I already do for much less!

So I’ll stick my hand up and say that I’m opinionated, and probably naive in terms of deeper politics. But, as with art, I know what I like.

Australian Political Landscape

It has always seemed, to me at least, that the great irony of the political system in Australia is compulsory voting in a nation where, on average, people could care less about politics.

Yep, that’s right: you need to register to vote once you hit 18, and you can get fined if you don’t vote at either State or Federal level.

How I see two-party politics…

Oh sure, there are some dyed-in-the-wool supporters, who will unleash spittle at a rate of knots in support of their party. I’ve seen people nearly come to blows on election day; old dudes who look ready to go into cardiac arrest at a moment’s notice.

If you want a rundown on the major Australian political parties, go have a read here: the Liberal Party (conservatives) are in a Coalition with National Party (farmers) to form our present Federal Government. While they have their own little internal horse trading, the Coalition, as they are known, are fairly solid when it comes to opposing stuff from the other side, and pushing economic liberalism.

At the moment, the other side are the Australian Labor Party (progressives). In a similar vein to their opponents, they love nothing more than saying “Those guys bad! We good! Vote Us!” but politically are all about social democracy.

The fanatics of either side probably think everything is great when their lot are in power, and rubbish when they’re in opposition.

There other other parties, the most prominent of which is The Australian Greens (progressive environmentalists). However, they only hold a small number of seats, and along with some independents and minor parties, form the “conscience” of the Australian people on certain issues.

The influence of the Australian Greens is obviously limited in the bigger picture, but occasionally they’ll hold the balance of power in either house (upper house = Senate; lower house = House of Representatives) on specific issues, often forming a voting bloc with independents who haven’t already done a deal with a big party.

When you live on a continent with this much good weather, natural beauty, quality beer, and generally high standard of living, it doesn’t really seem to matter. Most people I know are of the belief that, regardless of who wins, there will be pros and cons, and its not worth getting worked up about.

The majority of Australians probably fit in the middle of politics, and will vote based on their conscience, guided in some cases by the media (who have their own agenda).

Combined with compulsory voting, and a hyped up news cycle feeding on social media, it makes Australia an interesting political minefield. This has resulted in some states recently suffering single-term governments for the first time in decades, as one notable fact.

It seems that people are just willing to throw out whoever is in power; parties don’t win elections, they lose them.

In turn, the major party politicians constantly play he-said/she-said in terms of trying to score points. Its quite tiresome when there are more important issues to address – things that affect all of us, and are largely being ignored.

The Biggest Issue

Across the world at the moment, the threats posed by environmental destruction, and ongoing threat of man-made global warming, are going to affect us all.

It is right there. People know it is right there. If you’ve been paying attention in the last 10 years, you know there is a lot of rubbish talked about how its not right there. It is one of those things that some people see as a threat to their way of life, or some kind of charlatan’s trick to cripple the economy, so they work to undermine it.

In Australia, we have such a very large investment in coal, across all of mining, export, and thermal power generation. There is even a campaign called “little black rock”, which I will not dignify with a link, which seeks to tell people how releasing carbon is awesome.

Australia has an abundance of bright sun and strong wind, as well as the emerging wave power we can generate. We have the highest level of rooftop solar PV penetration at around 1.5 million households. We have some of the best researchers in the world on Solar PV, and lots of space to build the necessary infrastructure, both domestic and industrial.

Renewable Energy – Why So Negative?

The Coalition government are definitely not keen on it. Under their leadership we’ve had wind farms called “visually awful” and cited other impacts, all of which have been long held in contempt by science.

article-7818-hero
One of my favourites – click image for story @ Independent Australia

They reduced the RET (Renewable Energy Target) and have had an ongoing campaign against change in the status quo, in order to protect their conservative interests in mining and export markets.

They have run the clippers over our peak scientific body, the CSIRO, valued here and internationally for scientific research and technology development. The move is ostensibly to move from “analysis” to “adaptation” of climate change, but when you look at the CV of their CEO, and hear some of the comments about his time in Silicon Valley, you have to wonder.

It won’t surprise anyone to note that the coal and energy lobbies pour money into the Liberal Party like water.

The opposition Labor Party (yes, that is the correct spelling) have also got a quandary on their hands, particularly as they seek to protect their traditional battleground of workers’ rights and family issues. They can’t simply shut coal off tomorrow, because it would leave a hell of a lot of wreckage on the social landscape of towns supported by coal.

Nevertheless, they have announced some targets, which are nice, but really could be more ambitious. Labor have strong ties to Unions, and the CFMEU (Construction Forestry Mining Energy Union) are a big player.

The gradual decline of mining has seen job cuts aplenty, and IMHO Labor need to work harder to convince people in the Unions that Australia can pivot into renewable energy.

Ironically, both the major political players are running the dusty political principles of “jobs and growth”, but aren’t really putting up alternatives to the status quo, despite Australia’s recent exit from manufacturing and the ongoing slide in the mining sector.

There is also a genuine fear of fundamental change, in part due to the historical allegiances the big parties have, and the unknown quantity of renewable energy in a nation historically riding on coal. The latter is understandable, as mining is what kept Australia bouyant during the GFC.

But, we’re at record low interest rates. Record high housing prices. Coal prices are falling, mining is shrinking. This isn’t 2008 any more and the government can’t just muddle through on the back of the mining giants.

Where is the next big wave coming from? When all signs point to a new revolution, neither of the big parties have used renewable energy as a pillar in this campaign, both as an environmental and economic winner.

The Australian Greens – The Little Engine That Might

At present, The Greens are under the leadership of Richard Di Natale, who has brought a kind of pragmatism from his Senate position in Victoria.

It is unlikely they’ll win many seats, but the growing youth vote has seen them take several inner-city enclaves away from the big boys in the recent past at State and Federal level.

Along with disillusionment with the major parties, forthright leadership from Di Natale will assist the Greens wrest more of the vote away from the majors in years to come. Is this a good thing?

Perhaps, if for no other reason than getting the incumbents to change their thinking. More promising is the option to add a third voice to the decidedly binary view of Australian politics.

This change in rhetoric from the Australian Greens also dispels the myth that they are just a bunch of left-wing loonies, ready to bring down society and take us all back to peace-loving hippies with unrealistic expectations of love and peace. And kale … or something.

Renew Australia

Subtitled “Powering The New Economy”, the Australian Greens have released a document (PDF downloadable from that page), where they lay down the high-level principles behind fundamentally changing the energy economy, and several industries along with it.

Its worth a read, if for no other reason than to show that somebody is thinking about “jobs and growth” in terms that require a bit of a paradigm shift. The summary points are:

  • Ensure increases in energy efficiency
  • Get energy generation to 90% renewable by 2030
  • Establish a new authority to plan and drive the transition
  • Create a transition fund to assist coal workers and communities
  • Implement pollution standards to stage a gradual shut down of coal power stations in a suitable manner (dirtiest first)

All of these seem to be pretty reasonable, though I don’t doubt when some people read that – particularly those in the coal/energy industry – they’ll freak out a bit. And that’s OK, because change blows. We fear change.

The good news is, the Greens have released more detail about the transition process as it affects miners directly, as well as some dialogue on other policies via their website. Recognition of the issues facing people is not unexpected, as The Greens have a heavy emphasis on social equality.

Perhaps people still have this image of “Greenie” protesters who get all angry about people chopping down forests, or chaining themselves to mining equipment. Successive Greens administration have started to develop a more sophisticated approach to politicking, and it appears to be having an effect.

When I started this article, I’d planned a breakdown of the policy and the pros and cons of each bit. That would take a lot of words, and probably be a waste of time when you’re smart enough to figure out what the policy is about, by reading it yourself. So I’ll just look at one of the points above from a perspective close to my heart.

Energy Efficiency

When looking at how efficient the average Australian house is, people in Europe would be mildly shocked. The reasons why are probably more eye-opening, in terms of our building industry hitting the trough, and hard.

Overseas building industries started their push for better quality and efficiency decades ago. In Australia, labour costs are high and house prices surging, so adding extra cost is tough to accept. Consumer apathy is also a big factor, when you’ve got relatively cheap, abundant coal energy.

“Just turn on the Air Con!” is a pretty common statement. I’ve previously discussed the issues in my own house with ducted A/C (and associated muttering).

As a result, a lot of new housing in the last two decades is single-brick house with minimum ceiling insulation in the form of glasswool batts. If you wanted wall insulation, you’d pay extra in your new build in a lot of cases. Some didn’t even offer it, and I understand its extremely difficult to retrofit (i.e. ripping out internal walls)

We generally don’t do double/triple glazing, and just stick big reverse cycle air conditioners into new builds to cater for hot/cold days. No wonder we’re big electricity consumers!

People living in older weatherboard houses might as well be in a wooden tent. The farmhouse I grew up in had louvered windows and a big pitched roof, and yet somehow we got away without air conditioning in summer, and just a potbellied stove or combustion fire for winter.

Cold in Sydney right now – could really use one of these. AND, of course, the wine…

The great thing about seeking better efficiency, besides the obvious saving on heating/cooling requirements for the household, is the boost to the building industry in terms of jobs and growth (are you listening, major parties?). It also adds a layer of new requirements for retrofit options.

As new procedures and technologies are brought to bear, new opportunities crop up to establish service industries. This is especially important for people who might have skilled up in the practical arts of mining, and find themselves at a loose end.

A lot of people who went into mining got the training they needed, and can re-train to do something different in the building industry. Same for people no longer in car manufacturing after 2017. They’re smart people, and know the value of hard work. They need employment.

Better building practices can limit the upward growth of energy usage, as well as using the energy more intelligently. Along with home battery storage installed by companies like Natural Solar, smart control from Reposit Power, and better knowledge about how we use power, we can help limit the impact of change and minimise long-term costs.

The End Game for Coal

The Greens have put a shorter time limit on coal than the other political parties in Australia, recognising that this country has abundant natural resources for renewable energy generation.

They also acknowledge the practicalities of shutting down coal, and the social and financial cost in doing so.

However, their target of 90% renewables by 2030 leaves less than 15 years. In a political arena where The Greens won’t have the traction in Parliament to implement this kind of policy for at least the this Federal election, and probably the one after, you have to wonder where the impetus will come from.

With the falling price of solar PV, as well as the emergence of battery storage and the expected price drops there, I suspect we’ll see consumers have a big say in where the energy industry goes. The acceleration of uptake into battery storage, in particular, will force a rethink on network deployment and maintenance.

As I discussed in my last post, the Networks are interested in deeper consumer understanding.  They realise that working with the consumer on grid-connected battery storage is preferable to alienating them into off-grid battery storage.

The increase in domestic renewable generation will have a
knock-on effect to the domestic coal market for power generation.

External forces like the falling world coal price will apply pressure from the other end. Mining for coal will come under serious pressure, particularly if it requires more generous subsidies from the taxpayer.

We have existing oversupply on our current networks, which presents the opportunity to shut down the dirtiest power stations (looking at you, Hazelwood) in the shorter term.

The white knight for mining companies could be other resources, such as Lithium. The demand for lithium will only increase over the shorter term, as battery factories (like $11B facility planned by Volkswagen) ramp up production.

It almost seems like closing the circle: moving energy away from coal requires more lithium, which allows mining to move away from coal into lithium.

Or is that too good to be true?

I think  even with these factors considered, we’re still going to need one of the major parties to help the Greens get this type of initiative across the line before 2030. I wouldn’t be putting money on the incumbent Government to help if they get back in.

After all, you can’t spell Coalition without “Coal”.

CEC Guidelines for Battery Storage

It was with a gentle murmur that the Clean Energy Council (CEC) released its *deep breath* Install Guidelines for Accredited Installers – Grid-Connected Energy Systems With Battery Storage.

Editor’s Note: This post has now been edited for family appreciation. For those who wish to play Sweary Bear, replace any bold-underline-italicised words with whatever pleases you… 

It got a bit of coverage on Clean Energy Council but was otherwise under the radar, perhaps due to the relative nascence of these systems that will be both home- and grid-connected.

NCBI also covered the Case Of The Burning Battery reported in March, which should probably raise a few red flags in the industry about cowboy operators, more than anything.

growatt-1
That wasn’t supposed to happen… 

What I’m told by people on the ground is that the inverter caught fire, not the battery. Not that it matters once you’ve seen the way it was wired up (click on the article link), and where it was located (in a garage). You get a bit more of a feel for how it can go wrong, and why guidelines like this are important.

I’d never install battery storage in my garage because the door faces west, and the heat buildup when you park a car in there is what you might call sub-optimal. Throw in the fact that a lot of the battery storage units being imported are operationally rated to 40oC, and it paints a picture of best practice that most consumers should be able to understand understand.

I will point out the Powerwall is rated to operational temperatures up to 50oC, and then cease this smug digression.

As someone who has been enthusiastically engaging with various parties across the industry, as one of the initial Powerwall owners, I was keen to see how the CEC would tackle such a broad area.

There are a small number of systems in existence already that are completely bespoke, mostly in the sealed lead-acid domain (AGM etc). A number of these are off-grid, and therefore not subject to the guidelines.

In my opinion, the Guidelines have been prompted about the move towards consumer-grade equipment, targeting lithium in particular. It does talk about checking electrolyte levels “if applicable”, but these guidelines weren’t hurried about by AGM or flow batteries, that’s for sure.

Battery Storage Guidelines

After reviewing the document (click here for the PDF) the first time, I was particularly concerned by the general direction of the content.

And when I say “particularly concerned”, I mean “utterly livid”.

Page 17 contains the following (and you can see how raw this draft is, based on proofreading skills on par with my own):

That … kind of makes sense I guess. Looking at the options, and with the understanding my battery storage is mounted on the outside of the house, I’m going with “battery enclosure”.

That should be covered by the IP rated battery chassis and the weatherproof IP rated cover I’ve got, right? Right???

Uh…. What the deuce?

Maybe I need to count to ten, take a breath, and read further.

Maybe it isn’t just some nanny state bull dust gone mad, and that mitigation is in the detail.

Maybe we should skip ahead to Page 20 where we see this:

cec_pg20

I hasten to point out that both AS 62040.1.1 and AS 62040.1.2 are related to UPS. These storage systems aren’t actually UPS, so do we ignore that or not? And what constitutes “all in one” or the term “such as PCE and control gear”?

Back to Page 8 for more reading on definitions:

cec_pg08

Houston, we have a problem. Because we’ve got a lot of battery storage systems out there – and those being introduced – that do NOT meet this definition specifically, Powerwall included.

Some of the other manufacturers have this covered with a single box that I’m aware of, but in terms of outcasts, you’ve also just caged up units like Redflow and I believe Enphase while we’re here.

This is big trouble for manufacturers, who were trying to make batteries appealing using nice cabinets and cases. Now you’re going to need to consider specifications for caging the darn things up, like some kind of sad tiger in an Eastern Bloc concrete zoo, its nobility and grace forgotten.

Installers are going to be even more hesitant. Now all the wiring diagrams have to consider extra metal and framing (pretty good at conducting electricity I hear) as well as adding the cost and trouble to the install process, which will affect end users.

Going further back, into the section on 2 Scope we read:

cec_pg06

Again the (possibly incorrect) alignment with UPS standards, and the assumption that all-in-one systems contain everything, basically back to the panels.

Or does it?

But it also states that all-in-one had to contain the PCE, and reference it again on Page 9 under 3.1.5 Combined cabinet/enclosure the words “An enclosure containing both batteries and PCEs” but saying nothing about the inverter.

So which is it? If “all-in-one” different to “Combined cabinet/enclosure”, then why does the former need to contain the inverter but the latter contain only to the PCE hardware? Does that not automatically create overlap or confusion about where the document’s specifications sit?

Why aren’t inverters caged up or in a separate “battery room”? They’re just as dangerous as battery storage after all. We don’t have all those power switches and isolators for the fun of it – they are to keep the system safe to work on, and the people safe that work on them.

Are the “all-in-one” systems required to have suitable locks under the Australian Standards? Which AS document? This document doesn’t address physical locks required for these enclosures at all. If someone gets an enclosure, battery room, or fenced off area, is it OK to just leave it unlocked? The document doesn’t say. It does assume a lot, though.

My head is starting to hurt. I imagine a few industry insiders are looking sideways at this document, and wondering how they’re going to meet the bureaucratic mish-mash this could turn into.

Where Now?

I understand from speaking to a few people in the industry, that the CEC put this together in consultation with various stakeholders, and that its very raw. I think another round of reviews is required urgently, because this becomes a requirement, not a guideline, as of 1st October this year. Less than 5 months away.

No-one is putting a cage around my Powerwall. No-one is putting a safety sign on it, or near it, either.

The document makes multiple references to ensuring “unauthorised personnel” aren’t permitted access to the battery equipment, and that is a good point.

Rather than putting that on something as quaint as a sign, I’ll just use some common sense: if you’re on my property without my permission, you are unauthorised to be there, much less get close to my solar equipment or other possessions.

If you do not leave immediately, I will authorise my good friend, Mr Pickhandle, to assist you in any way we see fit.
