Sub 56 currently powers both AGL (block 24i to
32i) and piers uses. The new Sub 56 will cover only
the AGL block. A direct comparison between
current maintenance costs of Sub 56, and the
maintenance costs for the future Sub 56, is not
relevant as power requirements on new substation
will be different from the existing Sub 56.
Maintenance costs for airside AGL substation
approximately £12k pa. It is anticipated that as a
new substation is being built to house both Sub 56
and 87, economies of scale in maintenance will be
30% once sub 87’s circuits have been transferred
across (due to having only a single standby
generator, HV transformer and LV switchboard to
maintain). This will lead to a maintenance saving of
£4k pa.
