Thanks for the valuable tips @xdude and @rudra.  Good news to hear that hard disks of modern day are more resilient with outages and that load shedding has less of an effect than outage that is more sudden and due to a system fault.  This makes great sense @rudra as with the first load shedding event yesterday, my computer recovered much better than the previous outage that had happened because of a system fault.  That does make me feel much better already.  With the previous fault outage symptom was computer was extra slow - could hardly turn it on, and only way I could sort things out was to totally log out, shut it down, turn of the power supply and do the same with my WiFi power supply.  That more or less sorted it out then.  With the power shedding event in contrast, when I turned the computer on it went to the black screen in safe mode and Windows fixed itself (it hadn't done it before with the outages that had been as a result of a system fault).  

I have been looking at a UPS in a computer shop, but felt quite expensive.  The cheapest that allows for 30 extra minutes power down is 50 USD.  I've always used a surge protector for all of my desktop and TV electronics, but probably need to invest in a UPS.
