Every telephone exchange, every ISP, every commercial Data Centre, even every mobile phone tower has backup power.
When the floods hit the Hunter Region of NSW & knocked out power in 2015/6 for a few weeks, the mobile phones kept working - because there weren’t just batteries, there were diesel generators and contractors signed up to refuel them. We know this because it was documented in the Telco community.
So do many more ‘ordinary’ businesses, even high-rise buildings. Not to mention airports & control towers, radio & TV stations and major plant like Oil Refineries.
Grid Power is not, and never has been, a 100% guaranteed service: if that’s a problem for your business, you need to mitigate that commercial risk.
Even if you’re a big factory or industrial site, there will be unplanned outages of the external power supply.
Even something as simple as a vehicle accident taking out a pole, an animal short-circuits
Good managers take out insurance against ‘threats’ to production/income, as an integral part of their formal Risk Management Strategy
This is not odd or extreme behaviour, certainly not in high-value industrial plant….
And somehow that is now the taxpayer’s responsibility?.....
Every blast furnace operator has exactly the same vulnerability - lose power and you lose your primary income producing asset.
The plant operators will know to the minute how long it takes to do orderly shutdown & startup of the entire production line.
This will be formally documented in fine detail, with many checks & contingencies included.
So why did the management deliberately decide to not ‘mitigate' against this extreme impact event and like thousands of large industrial plants around the country have enough on-site power generation to do a zero-damage shutdown?”
