Transmission Grids

The existing grid was expanded by about 1,305 circular kilometers of overhead and underground lines, or 1.56 percent of what the size of the existing grid was at the end of 2018. Here's a breakdown of the additions:

· 199 circular km of ultra-high-voltage (UHV) lines in the 230-380 kilovolt range, 66km of which are underground and 132km overhead.

· 1,106 circular km of high-voltage (HV) lines in the 110-132Kv range, of which 356km are underground and 750km overhead.                  

Transmission Substations

· 54 new substations were built, adding 199 new transformers with a combined capacity of 24,000 megavolt-amperes to the grid.

· 26 more substations were expanded or refinished with a total of 39 additional transformers and a combined net power of 7,554MVA.

Fiber-Optic Networks

National Grid SA always has the latest, cutting-edge technology in its ultrahigh-speed fiber-optic network that stretches along its entire transmission grid to connect power plants and transmission substations across the Kingdom and enable national and regional control centers to control the grid reliably and in real time, with the ability to get readings and send commands instantaneously.

Fiber-optic networks are an essential part of Smart Grids because they facilitate the effective use of the latest, most modern technologies. As of 2009, the national power grid was being reinforced with interconnected networks of fiber optics, and each local network is constantly being reworked and expanded to ensure a solid infrastructure that is more than capable of supporting the company's operations and investment plans. As many as 4,286km of fiber optics were added in 2019 alone, for a total of 76,000km that is the length of the entire network, making it the region's largest fiber-optic network.
