Sharjah Electricity, Water and Gas Authority (SEWA) announced on 24 September that it had completed two electricity transmission projects. Its Airport Project connected seven main substations with 71.7 kilometres of underground 132 kV cable. SEWA reported a cost of AED235 million for that work. The second project upgraded 220 kV overhead transmission lines at a reported cost of AED106.493 million. These are the individually reported costs; SEWA described the combined cost of the two completed projects as exceeding AED341.493 million.

The authority also said work continues on 13 major projects, for which the stated total cost exceeds AED725.292 million. These projects are at different stages, including design and construction, so they are not completed assets. SEWA identified the 220 kV Al Shanouf substation at AED218.143 million, the 132 kV Al Ghubaiba substation at AED230.840 million, and the 132 kV Al Nahda substation at AED203.698 million among the major works underway. A separate Al Shanouf project is rerouting 13.4 kilometres of overhead line. These are announced project values and plans, not commissioned capacity.

Transmission lines and substations move electricity between generation sources and users in homes, businesses and industry. Underground cables can offer a different routing and land-use option in built-up or transport corridors, but the choice alone does not establish lower cost or higher efficiency. The network effect depends on connection capacity, demand patterns, maintenance and coordination with the existing system. SEWA says the works are intended to serve new residential, investment and industrial areas and ease pressure on existing substations.

Adding the two individually stated completed-project costs gives AED341.493 million. Because SEWA describes the total as exceeding that amount, this calculated subtotal should not be presented as the exact overall expenditure. For the 13 ongoing projects, the agency likewise reports a threshold above AED725.292 million, not a precise contract total. The announcement provides no completed transmission capacity, peak-demand change, technical-loss rate or change in customer outage duration. Without those measures, the quantitative service effect cannot yet be derived from this release.

Growth in Sharjah’s residential and industrial areas requires investment in both local distribution and higher-voltage transmission. The announcement does not describe the entire network plan or the emirate’s electricity supply-demand balance. Project costs are not operating outcomes: assessing performance later will require commissioning dates, completed deliveries, connection capacity and published reliability indicators. This report therefore separates the two works SEWA says are complete from projects that remain under implementation.

The accompanying table records the nominal AED values reported by WAM and makes no inflation or exchange-rate adjustment. Cable length and the number of connected substations refer only to the Airport Project. SEWA’s general description of using modern technologies is not a technical comparison or a measured performance result, so it should not be read as independent evidence of efficiency gains.
