Tasmania Labor unveils energy policy targeting 120% renewables, increased electricity exports, and an 80% boost to distributed resources like rooftop solar.

The Tasmanian Labor Party has pledged to take the state to “120 per cent renewables”, with an energy strategy that aims to lock in lower electricity prices and secure the island’s status as a clean power exporter.

In a statement released on Friday, ahead of the March 3 state election, Labor leader Rebecca White said her party would – if elected – “restore” and capitalise on Tasmania’s renewable energy advantage, with a range of new policy measures and targets.

Chief among these are a target of “more than 120 per cent renewables” within five years, and a “Distributed Energy Target” to boost on-site installations like rooftop solar by more than 80 per cent by 2022.

Of course, for Tasmania, a 120 per cent target is not as impressive as it sounds – the state regularly generates 100 per cent renewable electricity from its ample hydropower resources, and also exports to Victoria.

But White said the 120 per cent target was designed to make Tasmania the renewable energy “powerhouse” of Australia, allowing it to sell its excess hydro, wind and solar energy interstate – and in this way boosting the case for a second Bass Strait interconnector to Victoria.

The 80 per cent boost to distributed renewables is perhaps a more significant number, particularly in light of the state’s recent energy crisis, in which drought and a broken interconnector exposed its heavy dependence on hydro, and lack of back-up resources or plans.

In the end, the crisis left the the state-owned utility little choice but to resort to diesel gen-sets to make up the generation supply shortfall – a dirty and expensive venture that cost a total of $64 million.

Labor’s White said the current state Liberal government – which presided over this crisis – had failed to seize energy opportunities and, in doing so, had put energy security at risk.

“Not one major renewable energy project has been completed in the past four years,” White said on Friday. “Private investors have been left frustrated by a lack of urgency from the Hodgman Government.

“In contrast, Labor would create a more diverse energy generation system to reduce power bills, protect our energy intensive industries, provide energy security in times of drought and enhance the case for a second Bass Strait interconnector.”

Labor’s quite detailed policy plan also promises to reinvest $25 million in dividends from TasNetworks to fund a range of initiatives to take advantage of technological advances in renewable energy generation and storage – presumably including battery storage and internet of things solutions to load shifting and peak shaving.

Another key initiative targets the state’s agriculture sector, with a scheme designed to help farmers generate and use their own power.

“Farms are producing their own electricity through solar and wind installations, but as it stands their generation can only be used to offset costs behind one meter,” White said on Friday.

“A majority Labor government will work with TasNetworks to change the policy so that energy generated at one site can be used across all meters on the same property, provided it is used in real time.

“It is estimated the policy change could unlock more than $20 million in direct on-farm investment.”

The Labor policy also pledges to install solar and battery storage at every new public housing property built – up to 1000 installations over six years; and to create a virtual power plant of connected homes, businesses and government buildings that would contribute to the state’s energy security.

This last pledge bodes well for the solar and battery storage microgrid pilot project proposed for two towns in the state’s south east, which the Liberal government has promised to help fund if it is re-elected.

The Liberal Party has also pledged it will withdraw Tasmania from the National Electricity Market, cutting all ties with mainland pricing mechanisms even though it will still export and import power over its sub-sea cable.

Labor, meanwhile, promises to commit $7.5 million to a staged roll-out of electric and alternative fuel vehicles in the state, if it is elected.

Increased uptake of EVs in the state would also be a great way to use up that extra 20 per cent of renewable energy generation, other than exporting it to the mainland.

    Go Labor! Leading the energy transition in every state.

    (Yes, the Greens make the noises, but they’re not challenged with keeping a majority of the population happy. Doing that is hard work.)

    • Nick Kemp 9 months ago

      Labor probably need to keep the greens happy because that’s where their voters leak to.

      • neroden 9 months ago

        Yep. That’s the dynamic. If there’s a strong Green Party, Labor *has* to keep them happy. If there isn’t, Labor will backslide.

            All good if this site was one for political progaganda, but it’s not it’s one for rational discussion of energy markets. And many of us have deliberately avoided politics to hold to those principles. Then along comes this talent-less bullshit seizure-flasher gif artist political propagandist called Bighead and you know the rest….

          • Bighead1883 9 months ago

            When you fully mature Ren Stimpy,you will understand everything is political

            Most especially the gigantic thrashing of fossil fuel dinosaurs fighting for their very existence and the greedy corps wanting the biggest pieces of the renewables pie

            Oh and to help achieve these these winning strategies they`ll need voting for
            So,awake early on polling day,vote Labor,do it often,ha even borrow a bus and go to old peoples homes so you can take them to every polling booth in their electorate,and do give them tea & lamingtons

        …those matters wouldn’t be ‘Closing the Gap’, ‘The 10th Anniversary of the Apology to The Stolen Generations’ or ‘The Murray-Darling Basin’ by any chance?. These were the weighty issues of State that needed close attention this week. Instead we got the ‘duelling dickheads’ with their ‘duelling pressers’ showing how IMPOTENT the country’s leadership is ( although Baaananabee’s impregnator ratings climbed a notch ). The best that Two Tonguer Turnbull could come up with all week is his idea of policing the bedrooms of Ministers….the country can now relax as the most critical of national issues has now been addressed.

        • Rod 9 months ago

          The modus operandi of the COALition is to create a new flustercuck almost daily so people forget about the last flustercuck.
          I’m still waiting for the screaming banshee Cash to be hauled in by the bailiffs for sending the goons in attacking the union.

            Ah yes, the Cash. She loves a good police raid and organising the media to be there right at the moment when the AFP boys bust down the doors. Imma thinking that with the Cash’s policing experience she might be lined up by Two Tongues Turnbull to be the head of a new Ministry…The Minister for Policing MP’s Bedrooms. She would be a natural for this role….the journos with film and cameras rolling as the AFP boys crash through bedroom doors…of course it would only by Labor and Greens MPs that have their bedrooms raided!

          Issues of state are too hard, instead we get distractions from one side, and half-baked policy from the other. Thus Australia trundles on.

      “This in turn has motivated …Western Australia,”

      Correlation does not equal causation. It had no influence on the WA election whatsoever. It just wasn’t on the radar here. I can recall not one mention of it as an election issue in either the papers or on the radio.

      • Bighead1883 9 months ago

        My Oath,you must sleep like Rumplestiltskin
        Not only were renewables strongly favoured prior the March election
        but more than on the horizon 9 months later

        Of course one of our main pitches was also that we`d keep Western Power and not privatise
        I looked deeply into Labor policies for WAVotes2017 as I was a booth captain & scrutineer

        Roe 8 was a big issue as well I`m sure you`ll remember
        Something I knocked up in the last week of the campaign

        • My_Oath 9 months ago

          I’m not talking about about 9 months later. What happens 9 months later has no bearing on the election. It was not a motivating factor in getting people to (quite rightly) dump the Libs. The reason it is not such a factor in WA is because wwe are not part of the NEM. Voters here aren’t exposed to the nonsense that has gone on over east.

          • Bighead1883 9 months ago

            So you`re not talking about Jan 22 prior the election either

            Thank you for your time My Oath,I don`t feel we have anything to compliment each other about or discuss rationally

            AS this article points out,Labor is clearly getting on with the job of renewables in all States it governs and will do so in Tasmania should we win office there

          • My_Oath 9 months ago

            Labor is definitely getting on with the job of developing renewables in WA and I welcome their change of heart. Their track record has been obstructionist as they attempted to hold onto Collie-based CFMEU votes by obstructing grid scale solar and solar thermal.

            The rationality ceased the moment Labor’s renewables policy was claimed to be the reason they won the election. Good day to you.

          • Bighead1883 9 months ago

            Well bucko.I can`t let this discombobulation go unanswered
            From the bottom up

            You wrote ” The rationality ceased the moment Labor’s renewables policy was claimed to be the reason they won the election”
            No where have I said this,implied this or dreamt this ( as they say in journalistic circles,you have made up a total fabrication of facts)

            What you say here needs citation otherwise it makes absolutely no sense,in or out of context ” Their track record has been obstructionist as they attempted to hold onto Collie-based CFMEU votes by obstructing grid scale solar and solar thermal.”

            Labor won in WA because the LNP blew the mining boom,cut deals on a lower GST for other kickbacks from Feds,created the largest State debt of all time & and amongst other things the protectionism of Troy Buswell over so many years of his drunkenness and sexual proclivities
            Then the Bond/Bell scam cooked up by Nahan helped with the final nails in the coffin

            The problem the McGowan gov has is the PHON balance of power in the Council as they already have blocked the bill trying to raise gold royalties

            Miners are not paying their way { iron ore / LNG ) royalties need to rise but will not be allowed by LNP/PHON Council bloc

          • My_Oath 9 months ago

            “No where have I said this,”

            Yes you did. Remember this?

            > “This in turn has motivated … Western Australia,”

            The reasons you cite in this most recent post are the ones I agree with.

            As for the Labor’s previous obstructionist history, the former safe Labor seat of Kalgoorlie has been trying to get major solar development for decades. Both parties dragged their feet.

            The current city mayor, John Bowler, has similarly been a major supporter of solar development for decades – even back to when he was member of the Lower House in Perth – a Labor member. Their obstruction on the matter is one of the reasons he resigned from the ALP. And former Kalgoorlie ALP member and previous Leader of the Opposition Ian Taylor also resigned from the party in support.

            Thankfully the WA ALP has now taken their blinkers off and things can get moving.

            On Royalties, you might want to read up on the text of the royalty agreements before blaming the Libs. (The LNP isn’t a thing in WA and they went to the last election with a ‘raise thee Royalties’ policy if you care to recall.) The reason he government went for a gold royalty raise, and gold only, a few months back, is because gold is the only one the government can change at such notice.

            And no, I’m not a Lib supporter. I am firmly in the ‘a pox on both of them’ position. Both the ALP and the Libs have been obstructionist to solar development in Kalgoorlie.

          • Bighead1883 9 months ago

            Nothing to do with what I said? Did you not see my words where I stated it was a result of his support for Bowler? Sure, it was an expulsion rather than a resignation and I admit my error on that point, but its not like he didn’t know where his actions would end up – and I applaud Taylor for what he did.

  4. Jon 9 months ago

    The addition of more renewables will let Tas back off hydro production so when the next dry spell comes around again not only will they have more generation capacity but there should also be more water in the dams.

    Labour really is starting to move on with the transition to renewables, kind of makes the NEG irrelevant.

  5. Ian 9 months ago

    Good that Tasmania’s labor are promoting solar and distributed storage , 120% renewables, but they are trying to ride a wave that has already broken. Time to catch the next wave: EV, electrification of transportation, battery manufacture. This is a big wave, perfectly curved and will give any political leader an Epic ride.

    Please, please, please Rebecca, do a Jay Weatherill, and go all out for electric vehicles.

    • Be 9 months ago

      The solar wave is still cresting, it’s not a bad time.

      • Ian 9 months ago

        Read electrek.co, announcements by the major car manufacturers regarding EV are occurring thick and fast, many of the German car companies are building battery manufacturing capacity, 2022 seems the date for most EV product lines. At some point EV will be the predominant vehicle type. What will the energy landscape look like in Tasmania when no one wants to buy liquid fuels? How expensive will be petrol and diesel when this market shrinks to 1/10 or 1/100th of its present size? Anyone with the large storage capacity of an EV will want to take advantage of this for other purposes, besides the luxury of extended range, such would be interacting with the grid to 1. eliminate grid connection fees (off gridism) 2. Participate in demand management – particularly important in Tasmania where the wind resource is huge but the buildout is constrained by a very variable demand.

        Solar is something to promote but Tasmania has a little problem: Hobart average sunny days 44/365 partly sunny days 149/365, https://www.currentresults.com/Weather/Australia/Cities/sunshine-annual-average.php.

        Tasmania, amongst the Australian states is unique. It has fantastic centralised renewable resources : copious hydro and wind, but it has a relatively weak market for electricity. It also is not the cheapest place to supply fuel to. It has a problem of flight of capital – it has to pay for its fuel bill. Another good thing going for Tasmania is it’s small size , travel distances are not huge. This is a perfect place to test the EV microcosm. They could be attracting federal funds on pilot projects like EV incentives, EV V2G interactions, EV government vehicles, trucks, buses, microEV’s .

        • Ian 9 months ago

          Here’s an exercise for you : compare and contrast the energy landscape of Tasmania and South Australia.

          Rainstorage hydro: T 8 to 12TWh SA 0TWh
          Wind. T 1TWh. SA 4TWh
          Solar. T. 0TWh. SA 1TWh
          Gas/diesel. T 0.85TWh SA 5.6TWh
          Demand. T 10.5TWh. SA 12.4TWh
          Imports exports T Single 500MW Basslink.
          SA Heywood interconnector 460MW
          Population. T 520 000. SA 1.7 million
          Peak demand. T 1.7GW. Winter high SA 2.5GW summer high
          Minimum demand. T 0.9 GW. SA 0.7GW
          Industrial demand. T 60%. Mostly metallurgical industry – smelting
          SA many mine sites use their own generators roughly 1GW distributed FF generation not even accounted for in the SA tally
          Residential demand T 20%. SA about 24%

          As one can see SA has some very difficult circumstances to overcome in its road to 100% renewables electricity. They have some fantastic opportunities, namely the use of solar and/or wind /ff hybrid systems at large mine sites. Why is no one calling out this sector of the economy for not doing much to maximise renewables?

          Tasmania has a very benign energy landscape, having lots of hydro capacity which is very complimentary with water-sparing wind and solar. It has a comparatively large energy-hungry industrial base which is obviously very price-sensitive and probably relies on cross-subsidies from small residential and business users who suffer expensive electricity compared to these big users who pay very competitive rates. Distributed solar in Tasmania, because of the number of cloudy and partly cloudy days is relatively more expensive in Tasmania compared with mainland states. It would, however, draw the REC subsidy from FF generators in other States,which is a big win for Tas,

          Transport in Australia uses about as much energy in PJ as does electricity 1600PJ , hard to find the stats but Tasmania would use about 9TWh energy for transportation. Or 800 ML; at $1.46 a litre $1 billion. That’s how much money is hemorrhaging from their economy every year. Petroleum fueled vehicles have an efficiency of about 25%, EV closer to 95%. Simply put if Tasmania adopted 100% EV the electricity cost would be 9x .25 / .95 = 2.4TWH. What sized wind farm with a capacity factor of 45% would be needed ? 600MW. Cost of the wind farm at $2/kWh $1.2 billion. Cost of the electricity on heating and hot water tariff for example 17c/kWh $400 million. That’s a huge profit to the electricity generators. 300 000 EV cars and station wagons in Tasmania with on average say 20kWh to contribute to grid storage 6GWh storage, more than enough to allow the Basslink to export 500MW for 24/7 and for demand matching for renewables like wind and solar and tasmania’s Hydro.

          Play around with the figures and you will see that EV adoption in Tasmania is a ‘no-brainer’

          • Mike Westerman 9 months ago

            Excellent analysis Ian, but one that illustrates why even 120% is not enough. Adding to your thoughts on EVs, just the branding value of having hi value primary production being actually 100% Tas by using Tas energy should be enough incentive to go all electric in the transport sector, in addition to the import drain and lack of energy security imported FF imposes.

            There is a fair bit of activity in RE for mining, altho’ as another poster who is involved shows, 100% is expensive. Hopefully new PHES in SA will unlock considerable potential to push their target much higher and open the door thereby on their transport sector being electrified, including the mining sector where significant FF consumption occurs. It would in the same way put SA is a strong position to export high value RE to other regions.

          • neroden 9 months ago

            Having run the numbers recently, you’re right, 120% isn’t enough, it should be 150% in order to electrify transport (and still have some for export). Which is just a little bit more!

  6. Chris Baker 9 months ago

    Everything they can do to stop leakage of revenue out of the state will help their economy. Whenever they’re importing power from Victoria they’re exporting dollars and Tassie seems to do that about half the time. The figures I see on basslink indicate that that the imports and exports are about balanced. So there’s lots to gain there. On top of that they run their gas turbines a lot. Right now it’s 200MW on the NEM watch widget. That’s another chunk of revenue leaving the state. Electric vehicles would do the same thing… stop revenue leaking out of the state. Seems to me they can go wild with renewables and draw revenue into the economy. They are in such good position with all that hydro, not only because it flexible and perfect to balance variable renewables but they can spin their idle hydro as synchronous condensers to allow a very high penetration of wind and solar. They have so much headroom already without needing a second interconnector.

    • Tom 9 months ago

      Excellent observations.

      On Basslink imports/exports – Tassie requires about 11,500GWh pa including transmission and distribution losses, we generate about 9000GWh pa from hydro and about 900GWh pa from wind, leaving us dependant on imported energy for the remaining 1600GWh. (Of course, our hydro generation reserves can easily vary by +/- 2000GWh or more depending on the rainfall year).

      This 1600GWh shortfall is made up with either imported methane to fire Tamar Valley Power Station, or imported electricity via net Basslink imports.

  7. Mike Dill 9 months ago

    They should put in a substation on the bass-link cable for offshore wind connections. Plenty of space for offshore wind there.

  8. Tom 9 months ago

    I don’t want “perfect” to be the enemy of “good”, so I will give this energy policy a pass mark.

    Some parts of it are really good, whereas other parts are a bit clumsy. Tassie’s energy challenges are completely different from the mainland’s. Tassie has very little issue with meeting annual peak demand as long as we have water in our dams, and we have very little issue converting variable generation into our demand requirements. However, we do have an issue with supplying the number of GWh of energy per year that we require.

    Tas Labor’s energy policy appears written for the mainland. Particularly the focus on home battery storage. In Tassie, home batteries are the choice of the homeowner, but they will actually do very little to facilitate our grid.

    Rooftop PV has advantages above simple energy generation – it “brings people on board” and promotes interest and understanding about energy. However, it will probably never be a major contributor to Tassie’s grid either. Tassie has about 100MW of installed rooftop PV – at a generous capacity factor of 15% this works out to about 130GWh per year. Even doubling or tripling this will not go near making up our 1600GWh local energy generation shortfall.

    Which begs the question – where is the 4000GWh or so per annum to bring us up to 120% going to come from?

    If it comes from private investors it could well actually lock us into HIGH energy prices for years to come, depending on if they achieve generous power purchase agreements or not. PPAs are difficult in Tassie, because the government owns the hydro hence owns the ability to convert low-value variable generation into high-value dispatchable generation. Do we pay a “variable” price for the PPA, or a “dispatchable” price?

    Reducing dividends to government from the state-owned energy companies so that they can reinvest is absolutely the right thing to do. $25 million pa is a good start, $125 million pa would be better. It may cause an initial budget hit, but it would probably yield a 10%pa return on investment, compared with a government bond rate of 2.5-3%, so the initial budget hit would be paid off with interest in a short period.

    Developing an electric transport network is absolutely good policy, but in Tassie the lowest hanging fruit is probably the heavy freight industry (electric trucks). The longest single trip is around 400km, and we import more diesel than petrol. This was not recognised in Labor’s policy.

    So all in all, 7 out of 10.

    • Be 9 months ago

      Get Tesla in there and split the cost of home storage, but allow the utility to use it as a big battery, and the homeowners to get the backup and such. You have heard about that, right? Tesla is installing 600MW of home storage that will operate as one big battery.

      • Tom 9 months ago

        That’s what I mean. This setup is far more useful in SA than in TAS, where we already have over 2000MW of immediately dispatchable hydro power generation capacity – far more than our maximum domestic demand (around 1700MW). But only as long as there is water in our dams.

    • Ian 9 months ago

      120% renewables electricity is not good enough. Electricity is about half the equation .( There’s transportation, about 9TWh , gas about 1TWh).

      • neroden 9 months ago

        Switching transportation from petrol to electric replaces 80% electric drivetrains. As a result, you can remove more than 3/4 of that transportation usage if you switch to electric: replace that 9 TWh with 2 TWh.

        You can switch from 100% efficient gas heating to >300% efficient (not kidding) electric heat pump heating. So replace that 1 Twh with 1/3 Twh. (Though industrial users are a harder problem.)

        I can’t find current data but it looks like Tasmania uses about 5 TWh of electricity now. This means that renewables equalling roughly 150% of current electricity demand is enough to cover ALL energy needs.

          Tasmania uses about 11.5TWh of electricity per year including transmission and distribution losses. We use about 12-13TWh of liquid fuel.

          If 80% of our liquid fuel use was electrified we would require about another 3000GWh pa.

          Some FF drivetrains are well over 20% efficient – heavy diesels are into the mid-30s.

          Our domestic and industrial gas users use a very small proportion of the gas piped to Tasmania. About 75% of all gas is consumed by Tamar Valley Power Station, producing about 800GWh pa of electricity.

            Thanks for the data. My point stands. You currently use 11.5 TWh of electricity. You would need about 150% of that, which is to say 17 TWh, to electrify the entire transportation sector.

            Just do it. It’s easy; you have great wind turbine potential, and electric cars and trucks have enough range to cover all of Tasmania already.

            Another no brainer for Tasmania – the best wind resources in Australia, being smack in the roaring 40s. The combination of wind and hydro is perfectly complementary. They shouldn’t need diesel.

      Yes, great point, Tassie should look toward the success of small nations with large hydro resources. What renewables provide right now is dirt-cheap energy. What hydro grants implicitly is low-loss energy storage (water I don’t have to use today, is available tomorrow, and at slightly higher head). The two technologies create a complimentary situation where hydro is providing high-value dispatchable power, while renewables are providing the bulk energy.

      The only role for time-shifting and storage is to reduce distribution asset capital cost (i.e. might be cheaper than buying extra assets that are used two or three days a year) by ‘softening’ a peak load profile.

      As far as vehicles, frequently stopping, heavy vehicles, such as the short-haul delivery truck, school bus, and garbage collection truck give the best “bang for buck” on electric conversion, with less requirement for grid infrastructure upgrade than that required to support a private vehicle fleet, but substantial cost savings to the operator and wider economy due to the inefficiency of the ICE drive-train in handling such loads.

        For years, I’ve heard garbage trucks revving up to go 15 metres to the next property then screeching to a halt on their heavily used brakes and thought, why aren’t garbage trucks electric? Recover and re-use all that energy. It would save a lot of money in fuel and worn brakes. The Swedes brought one out a few years back. There must be more now.

    For a place with some of the best wind power resources on the planet (+1000 W/m2 @ +7.5 m/s in the South West and big hunks of the Central Highlands); about bloody time.

    I love this!

    Is Tasmania’s Labor Party the first party to campaign on a platform of MORE than 100% renewables (so that they can be a renewable exporter)? It may be the first in the world. It’s great!

    • neroden 9 months ago

      Now, to the practical question: can they win?

      I believe Tasmania has multimember STV. It looks like Labor can’t win an outright majority, but a Labor-Green coalition has a decent chance of taking the government. (I’m sure the Greens will sign on for THIS plan.) Unfortunately there may be enough Lambie voters to keep the Liberals in power.
