AEMO's vision – energy security for all Australians. AEMO plays an important role in supporting the industry to deliver a more integrated, secure, and cost effective national energy supply, for the long-term benefit of Australian consumers.
AEMO is honoured to undertake the role of independent energy market operator and independent power system operator in Western Australia.
On Monday 14 December 2015, AEMO was presented with the prestigious Western Australia Gas Industry Development award for our contribution to the domestic gas market via our work on the WA GBB, WA GSOO, and related data visualisations on our website. The award recognised the importance of these initiatives, which aim to improve market efficiency, transparency, and competition.
AEMO delivered strategic gas and electricity planning, and forecasting advice this financial year via the following reports.
The annual NEM ESOO models information provided by industry to report on the adequacy of existing and committed electricity supply in the NEM to meet the maximum demand and annual consumption forecasts over the next 10 years.
The annual NTNDP provides an independent, strategic view of the efficient development of the National Electricity Market (NEM) transmission grid over a 20-year planning horizon.
The NGFR provides forecasts of annual gas consumption and maximum gas demand across eastern and south-eastern Australia’s interconnected gas markets over a 20-year outlook period.
The annual GSOO uses the demand forecast scenarios from the NGFR to assess adequacy of gas infrastructure and resources to meet demand in eastern and south-eastern Australia over a 20-year outlook period.
The WEM ESOO is a key aspect of the Reserve Capacity Mechanism in Western Australia, which is valued at approximately $600 million in capacity payments. The Deferred 2015 WEM ESOO for the 2017–18 Capacity Year sets the Reserve Capacity Target (RCT), the quantity of generation capacity required in Western Australia’s South West interconnected system (SWIS) to ensure forecast peak demand is met between 1 October 2017 and 1 October 2018.
The NEFR provides trends in forecasts of overall electricity usage by electricity consumers, as well as forecasts of operational consumption and maximum and minimum demand from the grid in the NEM.
The changing mix of synchronous and non-synchronous generation means that the operational characteristics of the power system are changing, and AEMO is focused on the impact that these changed dynamics have on future power system security.
On 20 December 2015, a fault occurred on the Basslink Interconnector running between Victoria and Tasmania, separating Tasmania from the National Electricity Market.
AEMO undertook short-term modelling throughout the outage to confirm there were no generation supply shortfalls in Victoria or Tasmania as a result of the outage.
AEMO worked closely with Basslink, TasNetworks, Hydro Tasmania, and the Victorian and Tasmanian state governments to ensure the appropriate arrangements were in place while the fault was being resolved. The Basslink Interconnector was returned to service on 13 June 2016.
On 1 November 2015, an incident at transmission network service provider ElectraNet’s South East substation in South Australia, impacted electricity supply from Victoria to South Australia via the Heywood Interconnector, and separated South Australia from the National Electricity Market.
The outage resulted in a loss of 160 megawatts (MW) of customer load, causing electricity supply disruptions across regions of South Australia. AEMO worked closely with ElectraNet and SA Power Networks to restore load to the interconnector by 11.26pm.
The STTM Contingency Gas process was triggered twice for the Sydney STTM Hub in response to projected supply shortfalls.
These events were:
In both cases the Contingency Gas process was activated and the issues were able to be resolved through the renomination of pipeline flows without Contingency Gas needing to be scheduled.
There were two separate events impacting the capacity of the Brooklyn Compressor Station, which is a key facility in the DTS.
The energy market is rapidly evolving and consumers are demanding greater control and choice, while technologies and consumer behaviour are driving changes in generation, metering, storage, products and services.
AEMO continues to work closely with stakeholders to identify issues and opportunities for strengthening energy markets now and into the future.
One of AEMO’s strategic goals and core values is being impartial, balanced and thorough in our engagement with stakeholders on challenges and solutions. Our aim is to build stakeholder relationships that are collaborative and proactive.
A total of 177 participants contributed to the sessions, representing electricity, gas, government, and other user groups. The team aimed to facilitate an authentic engagement opportunity to exchange ideas and views.
In 2015–16, AEMO continued to make progress against its People Roadmap 2015–17. The overarching objective of the Roadmap is to deliver a highly capable, agile and engaged workforce.
Successfully integrated permanent and contractor employees from IMO into AEMO’s Western Australia office on 30 November 2015.
AEMO maintained its focus on the Healthy Minds and Bodies, Safe Workplaces, and Sustainable Workplaces programs. The highlights for 2015-16 financial year were:
of AEMO staff utilised counselling in the Employee Assistance Program. Comparative to the 3.7% industry standard
participation rate of employees in the free health checks initiative
In September 2015, we proudly launched our Sustainability Program alongside our Sustainability Commitment, which was developed through consultation with employees across the organisation.
Each year we recruit outstanding graduates to inject new ideas and energy into AEMO.
candidates were offered formal graduate positions
