Power in Australia’s power generation industry has become a matter of national concern after a massive outage left thousands of homes without electricity.
The outage in the Northern Territory last week saw a power outage of more than six hours, forcing many people to call home in the afternoon.
But in a recent report, the Australian Energy Market Operator (AEMO) said the blackout in Morpher, a community of about 6,000 people in the north-west of the country, was caused by “a combination of factors” including “the lack of a suitable backup generator, an unplanned maintenance operation, the power supply failing due to maintenance and repair work”.”AEMo has recorded instances of significant generation capacity failures during peak periods due to high wind conditions, but it is also possible that power supply failures are more common in low-wind environments,” it said.
“While it is likely that these failures were not caused by a fault on the generation side, AEMO has observed that the generation infrastructure in the community is poorly connected to other generation infrastructure and that power outages can lead to large power outage risk.”
The AEMC said it had identified a number of potential causes for the outage in Morphy, including “power failures” and “the need to replace the generation equipment”.
It said that on the morning of the Morpher outage, a generator had been disconnected from the network and it was not known whether it was connected to the grid or a generator in the nearby community.
“It is important to note that there was no evidence of a generator outage or any transmission failure, but a large number of homes were without power,” the AEMCO report said.AEMCO said that it was also aware of a “large number of complaints from residents about high temperatures and power outgassing”.
In the report, AEG said that while the Morphes power outage “was not unusual”, it did not reflect the level of risk in the state’s power system.
“The lack of backup power in Morphe is not unusual in the northern part of the state, and the Morphe power system is generally considered safe,” the report said, adding that while Morpheres power system was not “particularly resilient” it was “a significant concern”.
“Given that power failure in the region is uncommon, there is a risk that some households may not have power in the event of a power failure,” it added.
“This risk is mitigated by the presence of a large generator in Morpel.”
The blackout in the Morpel community of 6,700 people has left the power out for about half of the community.AEG said it would work with the community to resolve the issue.
“We have also undertaken a work to establish what, if any, mitigation measures need to be implemented to maintain the community’s safety and wellbeing, and are in the process of doing this,” the company said in a statement.AEC said that “many residents in the local community had concerns about the lack of power and that the community was in need of a reliable source of power”.
“These concerns were raised by the AEC and AEMS staff, and were addressed by AEME in the initial days of the outage,” the statement said.
“The Morphers power outage was not an isolated event and AEG has been in communication with the AEGA, the Morpean Council and other stakeholders throughout the incident to provide more information and support.”
Power outages are not uncommon in Australia, but the level and severity of these events is not as extreme as those experienced by the Morpurh community.
AEM has provided more than 10,000 hours of support to the Morper community through the PowerOutageWatch program.
“The Morpurhes power grid is the second largest in the NT after Port Moresby.
As part of that assessment, we have identified additional generators in nearby Morpurhas network and have provided those generators with additional assistance to ensure they are ready to respond to a power loss or outage,” it told the”
We are working closely with the local authorities and the Department of Emergency Services (DoES) to understand what additional measures can be implemented in order to minimise the risk to the public and the environment.”AEM has also provided the local council with a list of the emergency generators it has in Morper.
“As part of that assessment, we have identified additional generators in nearby Morpurhas network and have provided those generators with additional assistance to ensure they are ready to respond to a power loss or outage,” it told the
