Saudi Electricity Company (SEC) has finalised the implementation and operation electricity transmission and interconnection projects worth a combined $1.46bn (SAR5.5bn).
Located in the kingdom's Northern Region, the projects include six plants for the transmission of electric energy, and five aerial lines for electric interconnection between cities,
One such interconnection will involve a 380kV line between Tabarjal and Tabuk, according to Trade Arabia.
Khalid Al-Rashid, chief executive officer of the Saudi Electricity Company For Projects Development (SECPD), a subsidiary of SEC, said the projects are among the largest in the Northern Region, adding that they would support industrial and urban development.
Energy-efficient technologies integrated within the facilities are expected to result in savings of approximately 11.5 million barrels of diesel annually, in keeping with Saudi Vision 2030's diversification targets.
Al-Rashid pointed out that the projects awarded in April and May 2014 included construction of six main plants (voltage 380kv), namely Waad Al Shamal Plant, Al Qurayyat Plant, Tabarjal Plant, Al-Jouf Plant 2, Arar Plant and Tabuk Plant; as well as the construction five aerial line projects with a total length of 2,214 circular kilometres.
These include a line linking Al Qurayyat Plant with Waad Alshamal Plant, a line linking Tabarjal Plant with Waad Alshamal Plant, a line linking Al- Jouf 2 Plant with Arar Plant and a line linking Tabarjal Plant with Tabuk Plant, in addition to establishment of dynamic compensators at Al-Jouf 2 and Hail 2 plants.
He went on to say that the projects have added 2,214 circular kilometres of aerial lines to the national grid and the fiber optic cables have been increased at the same volume throughout the electric grid, a matter which will facilitate linking the plants’ systems with the control centers.
The total capacities of the transformers installed at the new plants amounted to 7.319 mva, and the total length of the external insulated rods, which were installed at the six plants, amounted to 31km, of which 12.4km relate only to Tabuk Plant .
“The projects will set a base for future electric link with Green Duba Generation Plant, in addition to the link with Al- Madinah region through East of Al- Madinah Plant, as well as interconnection with the national grid of the brotherly Arab Republic of Egypt. The King Abdullah Project for development of Waad Al-Shamal city is considered as one of the most important development projects in the region, which is being supplied with electric power from these projects,” Al-Rashid concluded.
