Qatar General Electricity & Water Corporation (KAHRAMAA) has successfully completed the testing and commissioning of the first substation at Msheireb Downtown Doha - the flagship development of Msheireb Properties.
The 66 kilovolt (kV) substation is the first energised underground substation in Qatar.
It was jointly designed and developed by Msheireb Properties and KAHRAMAA, with the latter providing internal design and electrical plans.
The substation is connected to the Ras Abu Aboud super-substation to ensure a reliable supply of electricity throughout the Msheireb project, which is the first attempt to sustainably regenerate the historical heart of downtown Doha.
Eng. Mohamed Al Dosari, KAHRAMAA's manager of electricity projects, said: "We are proud to have reached this milestone in the development of our country's power infrastructure by introducing the first underground substation design, in line with the sustainable ethos of Msheireb Downtown Doha.
"This ground-breaking technology will deliver efficient, cost-effective energy throughout Msheireb Downtown Doha in the most environmentally responsible manner.
Eng. Mohammad Masoud Al Marri, Msheireb Properties' chief officer for design & delivery, said: "We are proud to have Doha's first 66kV substation on the site of Msheireb Properties' signature development.
"The environmental considerations of the substation represent another breakthrough for the Msheireb Downtown Doha project team and underscore our long-term commitment to sustainable development and industry best practice."
The substation is part of Phase 1A containing a new Diwan Annex, Amiri Guard building and a new national archive as well as several heritage buildings, a mosque, district cooling plants and electricity substations.
It is being delivered by Qatari contracting company HBK.
Msheireb said the underground location was chosen for the substations to preserve the traditional character of the area. Alongside two 66kv substations, there will also be 40 11kV stations underground.
"Space and design were key considerations," said Al Marri.
"Having the substation below ground was the most creative solution to avoid disturbing the existing heritage sites within the Msheireb Downtown project and to make the best use of natural light and ventilation, as well as technologies promoting electricity and water efficiency."
