Arup was commissioned to carry out the design for infrastructure to support the Heart of Doha city development, including two underground primary substations.
The first fully-underground substation in Qatar is a pioneering design that is becoming increasingly the norm for urban substations.
Arup’s design reduced the substation footprint significantly compared to a traditional above-ground station of similar size. The work on the substations also included 66kV gas-insulated switchgear, 40MVA transformers and auxiliary systems – protection, communication and substation automation.
Power distribution network
In addition, Arup designed an extensive 11kV power network consisting of approximately 40 distribution substations fed from the two 66/11kV primary substations.
