DEWA has commissioned 793 new 11kV substations across Dubai during the first six months of 2026, part of an ongoing push to keep the emirate's power grid ahead of its expanding neighbourhoods, business districts and investment projects.
The construction and related works behind these new substations required 624,340 man-hours, according to the Dubai Electricity and Water Authority.
Reliability figures remain steady
Alongside the new substations, DEWA reported that its network continues to perform at a high level of reliability. The authority recorded an average of just 0.82 customer minutes lost for electricity annually, a measure of how briefly, on average, customers go without power over the course of a year.
DEWA also confirmed that its electricity transmission losses stand at 2%, matched by distribution losses also at 2%.
Scale of the network
With the latest additions, DEWA's infrastructure now includes 53 33kV substations in service, alongside 47,723 medium voltage substations rated at 11kV and 6.6kV, which together carry electricity from higher-voltage transmission points down to the level used by homes and businesses across Dubai.
Why DEWA is expanding now
Saeed Mohammed Al Tayer, MD and CEO of DEWA, linked the expansion directly to the pace of development across the emirate.
