The Australian Energy Market Operator (AEMO) released its draft marginal loss factors (MLFs) today. As generally expected, solar and wind farms that are a long distance from the regional reference point have been hurt.
The most notable example of this is the Broken Hill solar farm, which has a draft MLF for FY20 of 0.7254. This is 0.2535 below the current MLF. If the draft MLF is confirmed in the final report (due 1 April 2019), this will reduce the volume of electricity sold by the solar farm by 25%.
A number of other solar and wind farms had material reductions in MLF and are facing a challenging situation. Most notably, Silverton Wind Farm (NSW), Karadoc Solar Farm (VIC), Griffith Solar Farm (NSW) and Parkes Solar Farm (NSW).
MLFs are very difficult to estimate, which is reflected in the relatively large change we are observing year on year. Amongst many other concerns, this creates uncertainty for the investment community.

With expectations that CleanCo will be trading in the NEM by mid this year, things are getting into full swing. Last week CleanCo appointed its first two key executives – Miles George and Geoff Dutaillis.
Who are these new executives?
Miles George has been appointed the Interim Chief Executive Officer (CEO) at CleanCo. His role at CleanCo is to secure cleaner, more affordable, sustainable energy and secure supply of electricity for Queensland (QLD). He was previously the CEO and Managing Director of Infigen Energy. After leaving Infigen Energy in 2016, Miles continued as a strategic adviser until December 2017. During and after his time at Infigen, Miles has been the Chairman of the Clean Energy Council, a representative on the AEMC Reliability panel, an Expert panel member for AEMO and Director of the Australian Conservation Foundation.
Geoff Dutaillis has been appointed the General Manager of Transition. Geoff was most recently the CEO (Australia) of Wind Energy Holdings, a leading renewable energy company based in Thailand. The company has interest in various Australian wind farms. Geoff has also held executive positions at Infigen Energy as Chief Operating Officer (COO) from 2009 until 2013 and Lendlease more recently as Head of Sustainability.
What is the mandate for CleanCo?
CleanCo has the mandate to increase competition in the electricity market at peak times of demand when prices are generally at their highest. CleanCo is expected to transform intermittent renewable generation into firm financial products for customers and retailers while backing QLD’s renewable energy and low emissions generators.
Which of the existing generators are to be transferred from the current government owned corporations; Stanwell and CS Energy?
Initially, CleanCo’s portfolio will include a range of existing renewable and low emission energy generation assets including:
Wivenhoe pump storage hydro plant,
Swanbank E gas-fired power station, and
Barron Gorge, Kareeya and Koombooloomba hydro power stations.
If you have any questions regarding CleanCo or any other matter relating to energy, please contact Edge Energy Services on 07 3905 9220 or 1800 334 336.
Queensland (QLD) operational demand (see definition in image below) reached a new all-time record of 10,052 MW at 4.55pm yesterday (13th February 2019) largely as a result of temperature driven demand. Despite record demand, spot prices remained steady with QLD generators ramping up generation and conservative bidding from key generators.
Image sourced from AEMO
In terms of what type of generation was keeping the lights on, black coal and gas were the two largest contributing fuel sources (as shown in the image below). At the time of peak demand, 6,458 MW of generation was coming from coal and 2,253 MW from gas (natural gas and coal seam gas).
Should demand have crept even higher, Wivenhoe pumped storage
hydro still had capacity to ramp up generation to maintain stable pricing.

Edge Energy Services recently published an article on the 16th of January outlining what happens in the market when high prices and a lack of reserves are published in pre-dispatch. On the 24th January, it was a different story, where extreme temperatures and high demand in South Australia (SA) lead to load shedding, activation of RERT and operation of the emergency generators in SA. This resulted in the maximum price reaching $14,500/MWh with an average of $3,388/MW.
At the start of the week the Bureau of Meteorology forecast high temperatures across SA and Victoria (VIC) for the coming week. On the morning of the 23rd January, AEMO flagged extreme temperatures for SA and VIC and requested participants to update generation levels inline with expected conditions.
High temperatures and humidity have significant impacts on:
Performance of gas-powered generation and;
Energy usage of end users resulting in high demand levels.
In addition to extreme temperatures driving high demand, the loss of a Loy Yang A unit earlier in the week due to a tube leak. The reserve levels within VIC then fell to a point where LOR3 (Lack of Reserve 3) was activated. When LOR3 is activated, load shedding occurs.
At 15:00 an IRPM (Instantaneous Reserve Plant Margin) of 8% for the SA and VIC economic island was calculated. This indicated there was only 881MW of spare capacity in the islanded region. This information formed part of a report published by Global-Roam.
At 16:14 AEMO published a market notice stating a LOR3 had occurred and load shedding had commenced at 16:10. Changes in demand indicated 266MW of load was shed. The supply / demand balance changed during the day and reached levels where the LOR3 could be cancelled at 20:00.
Prior to load shedding, AEMO activated RERT (Reliability and Emergency Reserve Trader) at 14:24 which involves a combination of voluntary load shedding and demand side management. RERT was activated from 16:30 until 19:00.
During high price periods, most generators were operating at close to maximum capacity. The SA Emergency generators also ran between 17:00 and 21:15 adding 200MW to the grid. This volume assisted VIC via the interconnector flows. Wind resources were low in VIC and neighbouring regions, resulting in less than expected generation
The constraint N^^V_NIL_1, which effects the limit of capability through the NSW-VIC interconnector also bound resulting in a limit of supply to the region from Queensland (QLD) and New South Wales (NSW).
As a result of all the factors mentioned above, the spot price in VIC stayed at close to $14,500/MWh from 15:00 to 21:30. The diagram below highlights the resulting price, flows and regional prices for a 5 min interval of the day.
As a result of the high prices in VIC, the spot price for the quarter to date is currently $276.77/MWh compared with $119/MWh before Thursday.
Current contract prices for VIC are around $140/MWh for quarter 1 of 2019. Given these higher prices, users with existing exposure to the spot price would have been significantly better off if they were highly contracted. End users with the ability to change their exposure via demand side management would also have benefited from reducing demand.
As a result of the volatility yesterday the administrative price cap has been activated from 11:30am today. This will apply until prices decline below the price administered threshold.

At the end of the last week, AEMO flagged the possibility of extreme temperatures for the following week in South Australia, Victoria and New South Wales.
Weather forecasts were showing a large uncertainty in the predicted temperatures. Predictions ranged from mid to high 30s for Victoria, low to mid 40s for South Australia and high 30s for New South Wales. The key risk in these forecasts was the possibility of temperatures exceeding 40 degrees in two or more regions simultaneously.
On 11 January, AEMO published a market notice highlighting the forecast extreme temperatures in South Australia and elevated temperatures in Victoria and New South Wales. In this notice, AEMO provided forecast temperatures and generation capacity reference temperatures for generators to consider when updating their generation levels. Temperature and humidity have significant impacts on the performance of coal and gas powered generation.
On the back of this, AEMO updated its demand forecast and the resulting higher demand caused a lack of reserve to be triggered. The lack of reserve was forecast between 15:00 and 18:00 on 15 January. AEMO requested a market response from generators to make generation available to fulfil the shortfall.
Between 11 January and 15 January AEMO published further market notices updating the expected lack of reserve for 15 January and requested further generation response.
Pre-dispatch prices and demand for 15 January were published by AEMO the day prior. Spot prices were forecast to reach $14,500/MWh based on a demand of 8,800MW, which is significantly higher than normal levels.
As the afternoon approached, temperatures were high but a cool change was also approaching.
At 11:57 on 15 January, AEMO issued a market notice cancelling the lack of reserve.
As a result of the increased availability of generators and the cool change, AEMO revised their demand forecast down 800MWs. The resultant shift in supply and demand drove forecast prices down from $14,500 /MWh to $300/MWh.
Contract market prices are influenced by the outcomes of the spot market. As a result of the forecast high prices in South Australia,Victoria and New South Wales, the contract market prices increased in the build-up to 15 January; however, as the forecast spot prices and actual spot prices reduced, the contract market also reduced.
Retailers and large industrials are provided cover from the volatility of the spot market by purchasing contracts at a fixed price. However, the impact of the spot market can influence when volume is purchased to achieve the desired outcome for a business.

The COAG Energy Council met today for their 21st meeting. On the agenda was AEMO addressing their work in preparing the grid for summer, bringing down electricity costs and ensuring long term grid reliability and security.
AEMO highlighted the priority of work being undertaken to ensure that there is enough dispatchable generation in the NEM and integration of renewable and distributed energy resources. The Ministers agreed to a work program for the ESB to develop advice on a long term, fit for purpose market framework to support reliability that could apply from the mid-2020s. There was very little detail on this framework, however Edge will look to discover more.
Reliability
Ministers agreed to the final draft bill which gives effect to the Retail Reliability Obligation. The final package of rules will be brought to Council for approval in the first half of 2019, with a target commencement date of 1 July 2019.
Transmission upgrades
Ministers agreed on an approach to deliver the Group 1 transmission network projects. Group 1 projects include:
• Increasing transfer capacity between New South Wales, Queensland, and Victoria by 170-460 MW;
• Reducing congestion for existing and committed renewable energy developments in western and north-western Victoria; and
• Remedy system strength in South Australia.
In the Base plan, these initial transmission developments for Group 1 are costed at between $450 million and $650 million, and the assets will continue to benefit consumers well beyond the 20-year ISP forecast period. More cost benefit analysis work is to be conducted on Group 2 and 3 projects.

The electricity spot prices were generally higher for the winter period (June to August) than the preceding three months. The largest contributing factors were higher gas prices and increased demand for most of the regions. This excludes Tasmania where average prices fell from $80.26/MWh in autumn to $47.55/MWh in winter. Demand was still higher in the Tasmanian region, however additional rain meant that many of the hydro plants were running, as opposed to spilling water without generating. This put downwards pressure on the local prices.
The lower Tasmanian prices didn’t result in lower prices for the rest of the National Electricity Market (NEM). Across all regions, the prices during the 2018 winter were lower than the 2017 winter, however were still very high in a historical context. Looking back across the last 10 winters, the previous two (three for South Australia where Northern Power Station closed in May 2016) look like outliers. In fact, averaging the previous 8 years from 2008 to 2016, prices have been lower for all regions.
Figure 1: Historical prices for winter
It should be noted that prices in both 2012 and 2013 were affected by a carbon tax, which was subsequently repealed in 2014. Since then, there has been a steady price increase in all mainland NEM regions. The prices appear to have plateaued, however not reduced. In Queensland, the Government provided a direction to Stanwell Corporation to adopt strategies to reduce wholesale prices. Since the direction, there have been fewer price spikes (prices above $300/MWh). Although, the prices outside summer months are not reducing. Queensland is the only NEM region which had lower demand during winter compared to autumn. Price spikes in June caused by issues on the transmission network and lower availability at the start of winter kept average prices higher.
New South Wales had the same transmission issues as Queensland, and rolling planned outages at coal fired power stations meant that there was little spare base load capacity available. Victoria had high overall prices with few price spikes and was the only NEM region which didn’t have any prices above $350/MWh. Higher demand and gas prices kept overall prices high in the region. With lower availability in New South Wales, Victoria exported an average of 389 MW into the region compared to 57 MW during autumn. South Australia is heavily dependent on gas powered generation when there is insufficient renewable generation to power the state. This makes South Australia vulnerable to higher demand and higher gas prices, both of which were prevalent during winter. Prices were the lowest in three years, however still the highest of any NEM region. There is still a large amount of domestic gas usage in South Australia which means that prices tend to spike during winter. This occurred again in 2018.
The market didn’t run completely smoothly during the winter period. On Saturday 25 August 2018, multiple simultaneous lightning strikes on critical infrastructure caused load shedding. The lightning strikes occurred on the border between New South Wales and Queensland causing a loss of the main interconnector between these two regions. At the time, Queensland was supplying New South Wales with generation. The sudden loss of generation from Queensland caused load to be tripped in New South Wales. The loss of frequency also triggered a shutdown of the interconnection between South Australia and Victoria for reasons still being investigated by AEMO. This caused load shedding in Victoria and Tasmania. In total, 800 MW of load was lost in New South Wales, 280 MW in Victoria and 80 MW in Tasmania. This was predominantly industrial load which was reconnected within an hour.
Higher spot prices and concerns over the stability of the grid has caused the forward prices to increase. Snowy Hydro continued to draw down on its dam levels and with a dry outlook, the inflows could be lower than previous years. If Snowy Hydro reduces their output during 2019, spot prices could be even higher than current prices.
We are also seeing a separation between prices again. Though there were increases across all states, these were highest in Victoria ($16.56/MWh) and New South Wales ($15.88/MWh), and lowest in Queensland ($7.38/MWh).

There continues to be additional generation added to the market, mainly renewable energy. Going forward, it will be the integration of this renewable energy into the market which will ultimately determine if prices will reduce or if a more volatile market will be created. It is certainly unlikely in the near term that spot prices will return to historical levels (where the cost of energy during winter was in the $30s/MWh).
Looking forward
Q119 continues to be a period of concern across the market, as market participants continue to accept higher prices for swaps in the interest of reducing or removing exposure to spot prices. The BOM is forecasting hot and dry temperatures during the period, which are conditions that tend to cause volatile and higher spot prices.

In late 2017, the Energy Security Board (ESB) developed a scheme to provide investment certainty in the electricity market, which would address Australia’s commitments under the Paris Agreement.
The Coalition had ruled out a carbon tax, other cap-and-trade schemes and virtually any other scheme which had been attempted in the past. This left very few options for the ESB to appropriately address investment certainty in the electricity market. The ESB eventually developed an innovative scheme called the National Energy Guarantee (NEG). The basis of the NEG was essentially a cap-and-trade scheme for environmental certificates and, as a sweetener, it also had a reliability obligation. Essentially, the scheme was linked to contracts with retailers to make it sound like it wasn’t a cap-and-trade scheme. The reliability obligation would force retailers to purchase firm contracts if there was a reliability gap. The additional demand for firm contracts was thought to increase demand for firm generation.
The Australian Labor Party (ALP) was willing to support the NEG on the assumption that they would be able to increase the target for carbon reduction. The states were also largely on-board, on the basis that state-based schemes could continue under the NEG.
The new focus of the Federal Government will be reducing prices in the energy sector.
Prior to the legislation being enacted, Malcolm Turnbull was removed as Prime Minister. Even though Scott Morrison, the succeeding Prime Minister of Australia, had previously been supportive of the NEG, he conceded that it would no longer be acceptable to his party and declared the NEG dead. At the same time, the Australian Competition and Consumer Commission delivered a paper suggesting ways of reducing electricity prices. The new Energy Minister, Angus Taylor, was nicknamed the “Minister for Bringing Prices Down” declaring the new focus for the Federal Government in the energy sector.
Subsequently, the ALP has been quietly arguing for bipartisan support to potentially revisit the NEG in its entirety. Recently, Mr Morrison has been open to the reliability portion of the NEG being resurrected. Mr Morrison has expressed interest in meeting with the states and territories to discuss the possibility of legislating the reliability aspect of the NEG on its own.
While the NEG is still a topic of conversation in parliament, it seems that only the reliability obligation may survive.
As a whole, energy policy is shaping up to be a key differential in the next Federal election. In the meantime, we are seeing renewable projects going ahead across the entire system. Australia is well on track to meet and exceed the current 2020 target of 33,000 GWh of renewable energy across Australia. New investors in Australia are coming to terms with political instability, instead focusing on setting projects up directly with businesses that are considering their own schemes due to the lack of political leadership shown in Parliament.
As we come towards the end of 2018, the outlook is grim for bipartisan support of long-term energy policy; however, we may still have a way forward as consumers start to forge ahead of the political vacuum. The Federal government has warned against businesses forming a technocracy to effectively create laws, however given the failure of the government to provide an alternative, this may be the way that policies will be formed going forward.
The electricity forward price for 2019 continue to increase as fears around system security, adequacy of supply and stressed buyers increase.
Since the start of the financial year, forward prices across all mainland states in the National Electricity Market has been increasing. From 1 July 2018 to close of business 9 October 2018, CAL19 prices have increased by between $8.35/MWh and $18.78/MWh
The largest increase has been in Victoria, closely followed by New South Wales. Victoria has now overtaken South Australia as the most expensive region to purchase 2019 contracts.
Prices have been gradually increasing since the start of the financial year however since Monday 27 August, New South Wales and Victorian prices have increased rapidly.
Over the weekend we experienced lightning strikes on the border between New South Wales and Queensland. One of the main transformers was struct twice at the same time knocking out both the primary and backup line which is attached to the same equipment. The lightning strikes caused the interconnector between the two regions to shut down immediately to prevent further damage to the system. At the time, Queensland was exporting electricity into New South Wales. The sudden loss of electricity from Queensland forced an involuntary load reduction in New South Wales. This also dropped the frequency which may have been a contributing factor in shutting down the interconnector between Victoria and South Australia. AEMO is still investigating the exact cause however this led to involuntary load shedding in both Victoria and Tasmania which is an interconnected region. The majority of the load curtailed was industrial load and all load was restored within an hour.
The prices immediately started increasing when the 2019 market opened Monday morning. Late the next day (after the market had closed) there was another article in the Financial Review questioning the availability of generation due to drought conditions, particularly in New South Wales. The market had been tracking Snowy Hydro water levels, however the article also targeted Bayswater; a large New South Wales coal fired power station. In 2008, Bayswater was forced to curtail generation due to water shortages and could potentially be faced with similar restrictions again.
Though the market was already aware of the current water levels, there was more trading following the load shedding and the drought article. This could be a result of companies being keen to ensure 2019 contracts are in place in the event of further generation curtailments.
The market then seemed to settle again. Forward prices started softening due to lower spot prices in the back half of quarter 3. Late in quarter 3 the price then started to increase again. This was most noticeable in Victoria and New South Wales however it gradually spread to the other NEM regions as well. This is likely due to corporations fixing their 2019 contracts late, and a concern over 2019 spot prices.
Snowy Hydro continues to have little water and it is unclear how much it can generate during 2019. We are seeing generators bid to accommodate more solar PV. Some large generators are reducing their output to keep prices up in the middle of the day. If this continues, we may not see the price drop as some were hoping for.
The last driver is the market having the expectation that some consumers are leaving their contracting until very late. It certainly seems that the buyers are more distressed than sellers, making it difficult to buy cheaper electricity.
