Key Power Risks Facing Australian Businesses This Summer
As we approach another Australian summer, grid conditions are under strain. Severe weather, record breaking heatwaves and ageing infrastructure are increasing the risk of unplanned power outages across Queensland, New South Wales and Victoria.
For organisations that manage critical loads—such as data centres, EDGE, cooling systems and safety infrastructure—the cost of downtime can be enormous. Gartner estimates that each minute of unplanned outage can cost up to $8,595 AUD.
Power Quality Group specialises in uninterruptible power supply (UPS) and thermal solutions that help IT managers and facility managers maintain power autonomy to critical loads when the grid fails. To help you prepare for the coming heat, we've put together key insights and steps you can take now.
Key Factors Contributing to Power Outage Risks
| Factor | Evidence | Implication |
|---|---|---|
| Severe weather & cyclones | Tropical Cyclone Alfred in March 2025 left hundreds of thousands without power in southeast Queensland. | Sudden storms and heatwaves can knock out transmission lines with little warning. |
| Ageing grid infrastructure | Queensland's electricity network is decades old; faults are more frequent and repairs/maintenance cause planned outages. | Longer restoration times and higher likelihood of failures during peak demand. |
| High demand & transition to renewables | Record-setting heatwaves and the retirement of coal fired power plants strain supply, prompting predictions of widespread blackouts in NSW and Victoria. | Less reserve capacity and potential rolling blackouts/brownouts impact businesses. |
| Cyber threats | Experts warn that cyberattacks could trigger "cyber blackouts," targeting Australia's increasingly digital grid. | Outages could last longer and cause data loss, security breaches and operational disruption. |
Recommended Actions for IT & Facility Managers
Immediate Steps to Mitigate Power Risks
- Assess critical load autonomy and confirm UPS battery capacity covers at least the time needed for orderly shutdowns or generator changeover.
- Perform preventative maintenance on UPS batteries and thermal systems to ensure they handle high temperatures.
- Monitor outage maps using official sources (Energex for SE Queensland, Ergon for regional areas) to track real-time disruptions.
- Plan for extended outages by developing incident response plans and considering portable battery storage or onsite generators.
- Protect against cyber and surge risks by updating firmware, tightening cybersecurity protocols and adding surge protection.
- Educate stakeholders on emergency procedures and communication plans.
Cost of Downtime Analysis for Australian Businesses
The financial impact of power outages extends far beyond immediate operational disruption. According to Gartner research, each minute of unplanned outage can cost up to $8,595 AUD. For mission-critical operations, these costs compound rapidly:
| Duration | Estimated Cost | Business Impact |
|---|---|---|
| 15 minutes | $128,925 | Order processing delays, customer service disruption |
| 1 hour | $515,700 | Complete operational halt, data integrity risks |
| 4 hours | $2,062,800 | Supply chain disruption, contract penalties |
| 24 hours | $12,376,800 | Reputation damage, customer churn, regulatory fines |
These figures don't account for secondary costs such as:
- Equipment damage from improper shutdowns
- Data corruption and recovery expenses
- Lost productivity and employee downtime
- Customer trust erosion and brand damage
- Regulatory compliance penalties

Rising summer blackout risks: Queensland has experienced several large weather driven blackouts in 2025, including Tropical Cyclone Alfred in March and an incident in September that damaged transmission lines; these events left thousands of homes without power
-
High cost of downtime: According to Gartner (via Medianet), unplanned power outages can cost businesses up to US$5,600 per minute
-
Impact on mission-critical operations: Blackouts disrupt communications, cooling systems, security and data centres. Ageing infrastructure and delayed replacements mean there's less reserve capacity, making the grid more fragile
-
Rolling blackouts and brownouts can severely impact plant equipment and critical loads
