Turn off Meridian open letter to Mark Binns on why I am divesting from coal-pushing Meridian Energy

When is a renewable electricity generator not a renewable electricity generator? Or what do you do when the electricity generator who are claiming to supply your home with 100% renewable electricity enters into a commercial contract that keeps a coal-thermal power station emitting carbon dioxide for an additional four years?

Meridian Energy has recently signed a contract with Genesis Energy to keep the Huntly coal thermal power station open for four more years instead of closing in 2018.

New Zealand has made some predictions of future reductions in emissions that we have confidently sent off to the United Nations Framework Convention on Climate Change (UNFCCC). Unfortunately Meridian's action has had the effect of sending the emissions savings up in a puff of coal smoke.

So I decided to divest from Meridian Energy and move my account to electricity supplier to Ecotricity who own only 100% renewable generation capacity and who are certified as carbon neutral. I used the Consumer Power Switch website. There is also Whats my number web site.

I thought I should let Meridian Energy know I was voting with my account so I sent this open letter to Meridian Energy two weeks ago on 16 June 2016. I have not yet received a reply.

Re: Meridian Energy’s support for four more years of thermal coal electricity carbon dioxide emissions from Huntly Power Station

Dear Mr Binns,

I am a Meridian retail customer. My customer number is TrJ5I19vcteK2 My account number is 1.h@"]41Y6x#5-r.

I consider climate change to be a serious risk that we are all morally obliged to respond to. In 2012 I deliberately chose Meridian as my electricity retailer because of it's 100% renewable generation.

I am aware that to some extent the electricity I consume inevitably draws on some fossil-fueled capacity due to the networked nature of the grid. However, I was satisfied that choosing Meridian as my retailer was the best I could do in terms of reducing carbon dioxide emissions as I would not be contributing my money to any fossil-fueled thermal generation. In the past four years I have been very happy with that choice and with the service I have received from Meridian. Unfortunately, I did not know that Meridian had a contract with Genesis to keep the Huntly coal thermal power station operating to 2018.

On 28th April 2016, Meridian Energy announced that it had signed a new contract with Genesis Energy that would keep the Huntly coal thermal power station operating for an extra four years. This contract therefore postpones the expected closure from the planned 2018 date to 2022. I have read the statement on the Meridian website explaining the contract as a means of reducing the risk of low levels in the hydro lakes. The explanation fails to take climate change seriously.

The Fifth Assessment Report of the IPCC sets out very simply the carbon budget consistent with limiting global warming to less than two degrees Celsius. The global warming we will experience will be linearly proportional to the cumulative volume of carbon dioxide emissions emitted by humanity. To prevent further dangerous levels of warming with a reasonable probability, cumulative emissions cannot exceed the carbon budget. At that point, emissions must not exceed net zero.

As a matter of physics, the additional emissions that will come from Huntly for the extra four years will result in higher and more dangerous eventual global warming. Meridian Energy's actions have facilitated these additional emissions.

I find Meridian’s actions to be completely contrary to the IPCC's finite carbon budget conception of mitigation and with Meridian’s previous statements on renewable electricity. Those statements now appear very shallow and insincerely held to say the least.

Therefore, it gives me some satisfaction to inform you I am moving my electricity account to a 100% renewable electricity generator who has carbon neutral certification and who is not a party of the Huntly contract. It is my sincere wish that as many customers as possible who are concerned about climate change also leave Meridian.

Yours sincerely

I was alone the exporter had flown Norwegian Wood isn't it good

Geothermal Power Plant on Tasman Mill site, Kawerau NZ Norwegian wood and newsprint transnational Norske Skog Tasman (NZ) Ltd 'exports itself'. Mr February looks at the flight of another manufacturer and CO2 emitter and exporter as it lays off staff and reduces production. Wasn't the very generous free allocation of units in the New Zealand Emissions Trading Scheme meant to keep exporters like Norske Skog Tasman in New Zealand? Or have we just removed the price signal from exporters for no valid reason and stuffed the NZETS?

The other week Gareth tweeted about a good article in the Herald by Chris Barton.

Chris Barton reported that the Norwegian-owned newsprint-maker and transnational Norske Skog Tasman NZ had joined the ranks of export businesses like Rio Tinto Alcan NZ/NZ Aluminium Smelters who are exporting jobs off shore.

Norske Skog is shutting down one of two newsprint machines at the Tasman Mill, in Kawerau, due to lowered demand for newsprint.

At the same time Norske Skog is building a new $A84 million plant in Tasmania with some substantial help from the Australian Federal government (A$28 million grant) and State government (A$13 million loan).

Chris Barton noted some strong questions asked of the Government such as "what is being done for jobs"? And strong criticisms of the Government's naive "market will take care of everything" approach.

Chris Barton mentioned the NZ emissions trading scheme (NZETS) only briefly in passing, as he noted the rock-bottom NZ carbon price and the poor despairing carbon foresters.

So that prompted me to look at how Norske Skog Tasman NZ fits into the NZETS. What are the greenhouse gas emissions of the Norske Skog Tasman pulp mill? Is Norske Skog Tasman regulated by the NZETS? Have they ended up with a large free allocation of emission units (like NZ Aluminium Smelters Ltd) ostensibly to protect their international competitiveness and to keep the jobs in NZ?

Norske Skog Tasman uses geothermal steam from the Kawerau geothermal field for heating and electricity generation in its newsprint mill. Geothermal steam naturally contains carbon dioxide and methane which are released when the heat energy is transformed.

The use of geothermal steam for energy is covered by the NZETS as an energy sector emission. So Norske Skog Tasman must report its greenhouse gas emissions and obtain and surrender emissions units.

There is a specific emissions factor in the Climate Change (Stationary Energy and Industrial Processes) Regulations 2009 for Kauwerau's geothermal steam. The factor is 0.0275 tonnes CO2-2 per tonne of geothermal steam used.

Norske Skog Tasman's production of newsprint is included as an emissions-intensive trade-exposed activity eligible for a free allocation of 0.4911 emission units per tonne of uncoated newsprint, at the highest level of assistance; 90%.

So far, so much like NZ Aluminum Smelters/Rio Tinto Alcan NZ.

Let's start with a 'back of envelope' calculation of the units Norske Skog Tasman should surrender (the NZETS gross carbon price).

According to the Kawerau Geothermal Field Background Study, Mighty River Power supplies 285 tonnes of geothermal steam per hour to Norske Skog Tasman, who on-sell 26 tonnes to Carter Holt Harvey Wood Products. So net use is 259 tonnes per hour.

Assuming 24/7 production, the annual use is 259 * 24 * 365 = 2,268,840 tonnes of steam per annum. And 2,268,840 * 0.0275 = 62,393.1 tonnes CO2-e. So in a typical year, Norske Skog Tasman should be surrendering very roughly about 62,000 emission units under the NZETS.

How many free emission units were allocated to Norske Skog Tasman? In both 2010 and 2011, Norske Skog Tasman received the fifth largest free allocation of units (after the Smelter, NZ Steel, Methanex and Fletcher Concrete). In 2010, Norske Skog Tasman received 122,826 New Zealand Units (NZUs) for the six-month 2010 NZETS compliance period. In 2011 Norske Skog Tasman received 237,752 NZUs.

Assuming 24/7 production in 2011, Norske Skog Tasman was allocated 381% more units than it needed to surrender (237752/62393.1 * 100 = 381.0550). Thats a way more excessive free allocation than NZ Aluminium Smelters!

However, I might not have the right numbers. My calculation may be wrong. Why don't I ask the Environmental Protection Authority under the Official Information Act for the exact number of units surrendered by Norske Skog Tasman. Watch this space.

Alternatively lets look at Norske Skog Tasman's annual financial statements (PDF) for the 2011 calendar year.

Note 24 helpfully records that Norske Skog Tasman received 119,646 units in 2010 and 241,825 units in 2011. They surrendered only 10,754 units and sold 160,000 units, and had 190,717 units left at 31 December 2011.

The accounts show that in 2011 Norske Skog Tasman was allocated 22 times more units than it needed (241,825/10,754 = 22.49). The units allocated to protect jobs and export competitiveness, were not 90% of units surrendered. They were not 100% of units surrendered. The units allocated exceeded the units surrendered by a factor of 22!.

I can still here an echo of voice saying "You have left out the electricity allocation factor! You are wrong wrong wrong!" Well, yes, the industrial free allocation factor of 0.49 units per tonne of newsprint allegedly includes compensation for NZETS-related electricity price increases our manufacturing emitter is subject to. This rationale and the factor of 0.49 units per tonne were approved in this Cabinet paper. However, the cabinet paper provides no explanation of how the factor of 0.49 units per tonne of newsprint was calculated.

The electricity allocation factor has also been the subject of a consulation process and there is an emitters contact group for it as well.

However I think the idea that manufacturing emitters need compensation for NZETS-related electricity price increases is a smoke-screen. Norske Skog Tasman has not had its electricity price increased by the NZETS.

According to the Kawerau Geothermal Field Background Study (PDF), Norske Skog Tasman and Mighty River Power (MRP) have "..a power purchase agreement whereby NST (Norske Skog Tasman) contracted to take a majority of MRPs generation. Due to the fact that MRPs plant is grid tied, this is effectively a financial agreement offering NST price certainty and MRP a customer contracted to take the majority of supply."

The Tasman Mill is not just a plant connected to the grid. It was built to use geothermal power, just as Tiwai Point Smelter was built to use Lake Manapouri's hydro power. The Tasman Mill is joined at the hip to the Kawerau geothermal field. The newest Mighty River Kawerau geothermal generation plant was built on the Tasman Mill site. Norske Skog is buying geothermal steam from Mighty River Power and paying MRP as if it was electricity via a financial derivative contract.

To conclude the free allocation part of the analysis; in the example of Norske Skog Tasman, the NZETS free unit allocations are not just a discount of the full NZETS carbon price, the allocations are a transfer of substantial corporate welfare. The units allocated exceed the units they have to surrender by an estimated factor of 22.

And in terms of protecting the international competitiveness of Norske Skog Tasman and keeping jobs in New Zealand, the free allocations have not made the slightest difference. Thats in spite of National Party scaremongering back in 2008 that the NZETS would cause the mill to close. And Catherine Beard of Business New Zealand (formerly boss of the Greenhouse Policy Coalition) still scaremongering in October 2012 that any real cap in the NZETS will cause more job losses Talk about slamming the stable door after the horse has bolted.

Lets look at the real factors affecting whether a commodity manufacturer stays in New Zealand.

If you are a transnational like Norske Skog, you always have the choice of playing off more than one jurisdiction. The country with the smaller economy, like New Zealand, can't match the money of a larger economy like Australia. If Norske Skog had not purchased the Tasman Mill from Fletcher Challenge in 2000, this 'regulatory arbitrage' would not be possible.

Corporate aquisitions that seemed a good idea before the Global Financial Crisis, look much more risky after the Global Financial Crisis. Norske Skog paid $NZ5 billion for Fletcher Challenge's paper and pulp assets. In 2011, Norske Skog was faced with falling international demand and prices and it was considering selling some assets to avoid default on its debt.

Incidentally, Rio Tinto Alcan shares most of these international commodity trader issues; the over-priced debt-funded purchase of Alcan and Comalco by Rio Tinto before the GFC, the Rio Tinto's plan to sell Pacific Aluminium (including NZ Aluminium Smelters Ltd), the low demand for aluminium from the stagnant economies of the Eurozone and the USA and the price and supply competition from Chinese smelters in the huge and growing Chinese market.

Imagine a fictional conversation between John Key and the CEO of Norske Skog.

"So, Yon, you don't mind if I call you Yon? For the Tasman Mill, you kiwis are all online, the demand for newsprint is down. You give me quarter of million of these NZ units that are worth $NZ3 each. No other ETS accepts them. Thats pretty low quality carbon credit, Yon. Now, Yulia Gillard, she gives us $A28 million for new plant at the Boyer mill in Tasmania. Can you match that, Yon? Can you?"

That is the bottom-line, isn't it? New Zealand could never have matched $A28 million, either as a direct grant, or through manipulation of the NZETS free allocation provisions.

To me, the Norske Skog Tasman job losses are a good demonstration of how futile it was to have an NZETS designed mainly to completely avoid any carbon price on transnational exporters. The carbon price has not just been reduced or discounted to Norske Skog, the sign has been reversed so that its an off-balance sheet transfer of corporate welfare to them in the form of emission units. Such transfers are no doubt sought by local managers who are rent-seeking, but they will be irrelevant to the international commodity trade movements that will ultimately determine whether these transnationals stay or go.

New Zealand Aluminium Smelter Ltd do a Godfather; Nice smelter you got. Be a shame if something happened to it

The Godfather Robin Johnson's Economics Web Page argues that Rio Tinto-owned New Zealand Aluminium Smelters Ltd, the owner of the Tiwai Point aluminium smelter, is "Godfathering" the smelter, its workforce, the Southland economy, the NZ electricity market, Meridan Energy and the poor critically endangered slow-breeding kakapo, as well as "Godfathering" the NZ emissions trading scheme to get excessive free allocations of emissions units.

I have invented a new term for climate change blogging.

Godfathering!

Its a bit like Grandfathering, which is a bit of jargon from emissions trading. But different. Grandfathering in an emissions trading scheme (an ETS), is giving the emission units for free to the existing emitters in the ETS on a historic pro-rata calculation.

The units of course representing the desired cap on emissions. Alternatively the units could be sold by auction to emitters which is logical if we treat the units as shares in a public commons owned by the Government on behalf of citizens.

Of course our NZETS is not so simple. If our NZETS just applied simple "grandfathering" as outlined, then it would have a real cap, it would not allow importing of unlimited international units, and it would be impossible for any emitter to receive more units than their emissions.

Thats not the case under the NZETS, at least for some emitters. In 2010, the Rio Tinto Alcan subsidiary NZ Aluminium Smelters Ltd, which is roughly New Zealand's third largest point source of greenhouse gas emissions, was a net seller of units, not a net payer. Their free allocation of units was 135% more than the units they needed to surrender for their emissions.

That's excessive. The justification given for this is that in order to maintain their export competitiveness, NZ Aluminium Smelters Ltd needed to be compensated for the rather unfathomable and diluted ETS costs that may flow through their secret contract with Meridian Energy and the electricity wholesale market. I will come back to this later in the post.

Let me update the smelter emissions and unit allocations for the 2011 year.

In 2011, NZ Aluminium Smelter Limited produced 354,030 saleable tonnes of aluminium. The 2011 Ministry of Economic Development Chief Executive's Report shows that the New Zealand aluminium manufacturing sector (a.k.a. NZ Aluminium Smelter Ltd) reported emissions of 601,370 tonnes CO2-e for the 2011 year. We divide by two for the 'two tonnes for one unit' deal, and that results in 300,685 units to surrender.

The NZ Ministry for the Environment allocated 437,681 units to NZ Aluminium Smelter Ltd for the 2011 calendar year.

That's 136,996 more units allocated than surrendered or alternatively the units allocated to NZ Aluminium Smelter Ltd exceeded the units surrendered by 146%.

So that's even more excessive than 2010's 135% over-allocation!

How did NZ Aluminium Smelter Ltd/Rio Tinto Alcan NZ Ltd achieve that? Simple really. They threatened to close the smelter and move production offshore if the NZETS really imposed a real carbon price on them.

"Thats a nice aluminium smelter you got. Be a shame if something happened to it."

Now thats what I call "Godfathering"! But wait there is more.

In July, NZ Aluminium Smelters announced an annual loss.

The smelter CEO Ryan Cavanagh said the smelter's financial difficulties were due to falling world aluminium prices. And that they needed to revise their electricity supply contract with Meridian Energy to get input costs down.

A day later, the parent company Rio Tinto Alcan indicated what may happen to it's unprofitable smelters. They will be shut down. No pressure, Meridian Energy!

"Thats a nice aluminium smelter you got. Be a shame if something happened to it."

According to New Zealand Herald economics editor Brian Fallow, if the smelter closes, there could be a "seismic" knock-on effect on the electricity market. Supply would exceed demand by the 14% of New Zealand's electricity generation used by the smelter. Wholesale electricity prices would react. Some generation assets might be crowded out.

"Thats a nice wholesale electricity market you got. Be a shame if something happened to it."

Brian Fallow notes the electricity contract with Meridian Energy, that the smelter wishes to renegotiate, represents 40% of Meridian's sales. Closure of the smelter or renegotiation of the contract put the spanner of uncertainty into the Government's planned partial sale of Meridian and the other generators.

"Nice plan for partial privatising some state-owned power generators you got. Shame if something happened to it."

The closure of the smelter would also have an impact on the local Invercargill and Southland regional economy.

"Nice regional economy you got. Shame if something happened to it."

Next we hear that the smelter is fast-tracking the redundancies of it's highly-trained and highly-paid workforce.

"Nice well-trained professional smelter labour force you got. Shame if something happened to it."

Strigops_habroptilusAnd NZ Aluminium Smelter also wants to withdraw from partly funding the successful Kakapo Recovery Programme.

"Nice charismatic endangered species programme you got. Shame if something happened to it."

That's a lot of Godfathering!

Let's look at New Zealand Aluminium Smelter's electricity use and costs in 2011. How much do they use? How much do they pay? Does their power cost justify extra allocations of emissions units? Is it realistic for New Zealand Aluminium Smelter to try to get Meridian Energy to give them cheaper power?

New Zealand electricity use data is available from the Energy Data File 2012. The specific data is Spreadsheet G worksheet G.6.a. now at stored Google Docs.

Electricity use by sector 2011

This dotchart is of electricity use data from the sheet G worksheet G.6.a.

The chart makes it very clear that the Tiwai Point Smelter is, by a huge margin, the biggest single consumer of electricity in New Zealand. A single company at a single plant used 5.3 million MWh out of 38.8 million MWh consumed in 2011, or 13.67% of the total consumption. Only the combined 4.4 million people in homes (the residential sector) used more, with 13 million MWh or 33% of the total. If we just look at industrial use of electricity, and leave out the residential sector, the smelter uses 20.6% of all electricity used by industry.

Electricity sales price by sector 2011

This chart shows industrial electricity sectors sorted by average rate (including line costs) in cents per kilowatt hour (i.e. its MWh divided by sales $$ times 100). You need to look at the bottom left hand corner for aluminium smelting, not the top. Thats because NZ Aluminium Smelter Ltd pays the very lowest average rate for electricity in New Zealand; 5.03 cents! Residential users pay 22.6 cents per KWh, or four times as much.

No industry in New Zealand uses more electricity than New Zealand Aluminium Smelters. No industry pays less per unit for electricity than they do. They even get excessively allocated emissions units to help with the lowest priced power contract in New Zealand. And now New Zealand Aluminium Smelters are going for "Godfather" gold by trying to bully their power price even lower.
