Powering the Shard

Former Community Member
Former Community Member
Afternoon one & all


I know we have single and three phase power, single mainly for domestic and three phase for commercial and small industrial.  But what sort of supply would The Shard have, does it have several 3 phase supplies or does it have an even higher supply that is then lowered via step down transformers to supply the various floors etc?

    I presume that the problem is one of legacy equipment and use of existing cable ratings, as there are plenty of 33kV to 400V transformers on the ends of long lines in very rural places, so it can be done, just maybe not in the middle of existing system.

     


    Sure it "can be done" - but no single developer wants to pay the burden of sorting out infrastructure - they only want to pay the minimum for their little bit - hence the UKPN approach of pushing up the voltage to wring what they can out of the infrastructure locally.


    Curiously, we also see a lot of infrastructure going the "other way" - two recent projects have both had 10kV infrastructure used rather than the more traditional 11kV
