looks like a deliberate attack and not a breakdown.

Looks like we're about to find out what happens when part of the developed world loses electricity supplies for an extended period of time. It's not like they can just restore the cut lines, especially if they were blown up on purpose.

Indeed, though it appears that some electricity is available from gas turbine plant.
This can be expensive and is of course reliant on an ample supply of gas or perhaps light oil*
I expect some panic over supplies of batteries, candles, LPG, and kerosene, and for business premises generators.

*Most industrial gas turbines are optimised to burn natural gas, but can also burn light oil. Often the warranty allows only limited oil burning.

I've always thought pylons would be an obvious target. A little bit of research could identify a few critical parts of the uk supergrid. Simultaneously taking down half a dozen pylons one January afternoon could have huge ramifications.

Yep. Relatively easy to take down if you have access to explosives, without getting caught. Which means it is impossible for the Russians/Crimeans to even know whether it was the work of the Ukrainian authorities or of militant groups acting on their own, let alone prove it. And even if they are re-erected, you can't police them all so they will just be taken down again.

And the Russians can't just rustle up an alternative supply across the Kerch Straight, because it would have to be major power line crossing a busy shipping lane. Do-able, but not in a couple of weeks. They started building a bridge there in May this year, but it is not due to be completed until 2019.

Yes, this has concerned me for some time.
Although a damaged pylon could be replaced, with military assistance if need be, whoever did it once can repeat the attack a few miles away.

No need for explosives, all you need is a spanner. I'm surprised it hasn't been done already.

Pylons would probably cause quite short term disruption. It's a much bigger problem if transformers are targeted as the big ones have lead times of months or years.

Fortunately I've got a couple of generators (1 petrol, 1 diesel) which could prove useful for a short term power outage - not for weeks though as per adam2's tag line. Cool

Reports on Al Jazeera say that it will take 48 hrs to get power back to Crimea...
