Last week’s extreme weather is bringing greater focus to how our changing climate can increase risk to the network and the delivery of power to where it’s needed. Our Head of Transmission Verity Watson asks: is our critical grid infrastructure built to withstand increasingly intense storms, and where to from here? #energynetworks #netzero #transmission #ena #storm #infrastructure https://lnkd.in/gpnN337b

Good piece - the extreme convective downpours seems like a technical term for a minicyclone or tornado. These are the particular nasty that has emerged from climate change. Good to know the new standard is designed to withstand these and unsurprising that the old standard didn’t. Three actions to improve resilience (1) work with BOM to identify areas that might be at greatest risk from these storms - I suspect they hit on wide open plains. Then put some movement measurement devices on sample towers to monitor wind effects. In areas of high risk strengthen towers. (2) review protection systems to prepare for previously unexpected sudden losses of transmission (3) revise dispatch algorithms to artificially derate at risk transmission lines so there are more alternative resources available (4) start taking seriously the importance of high penetrations of DER.
