The data flow from the grid also helps the utility to restore supply
faster after an outage. Disruption to power supplies
, potentially on a large scale, is likely to take on greater significance as climate change leads to more extreme weather
happening more frequently. Some examples: in 2016 a violent storm reported as being a once-in-50-years event ripped across South Australia, knocking over pylons and damaging the inter-connectors that govern the flow of energy between networks, leaving most of the state without power. In October 2018, Californian utility Pacific Gas & Electric had to shut off power
for 60,000 customers to reduce the risk of starting wildfires as storm force winds pushed power cables together, causing them to spark. The wildfires that devastated parts of Australia at the end of 2019 amid soaring temperatures and high winds are another example.
