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?

    11kV/20kV step up transformers

    That surprised me!

    Not that uncommon in that part of town - it's the only practical way to wring more out of existing infrastructure. 20kV is becoming an increasingly normal supply intake voltage in some UK cities.


    The choice of internal HV distribution voltage is principally driven by size constraints (every m2 of riser is space on each floor that can't be let) - 20kV again is becoming increasingly common on taller buildings (which follows a similar philosophy on tall buildings across the globe)


    It does raise an eyebrow for UK centric engineers.
