In just under one year, Bells has secured three major projects adjacent to each other on London’s Cannon Street, which we’ve dubbed the Walbrook Triangle.

Between them, the three buildings offer an impressive 1.4m sq ft of office/retail space.

On completion of the phased work, Bells will have installed a total of 13.7 MVA of standby diesel generators comprising 3 x P1700P (HV), 3 x P1700P (LV), 2 x P1500P (HV) and 1 x P500P (LV) prime rated generator sets.

Each of the buildings will have complex dual hot/standby PLCs controlling all major MV and LV switches, as well as carrying out power management services (PMS) duties of tenants busbars and tap offs.

Bells provided a complete turnkey service for all of the buildings comprising:
