GE and L&T to provide GIS substations for Saudi’s largest green hydrogen plant

GE Grid Solutions has secured a contract with Larsen & Toubro to supply three 380 kV T155 gas-insulated switchgear (GIS) substations for the  largest utility-scale green hydrogen plant in Saudi Arabia.

The green hydrogen plant will be situated in Oxagon, a planned smart city within the NEOM area in northwestern Saudi Arabia. The NEOM Green Hydrogen Company (NGHC) aims to produce carbon-free hydrogen at the plant using wind and solar power, with a target production capacity of up to 600 tonnes per day by the end of 2026. Under the agreement, GE Grid Solutions will be responsible for the design, manufacturing, supply, installation, and commissioning of the 92 bays of GIS required for the plant. The company’s GIS design, incorporating a 1.5-breaker configuration, will ensure reliable and uninterrupted power supply for the hydrogen plant, as well as the accompanying wind and photovoltaic (PV) plants. Meanwhile, Larsen & Toubro was awarded the engineering, procurement and construction contract for various elements of the project, including a 2.2 GWac PV solar plant, a 1.65 GW wind generation balance of plant, and a 400 MWh battery energy storage system. It will also construct three 380 kV substations, 306 km of 380 kV overhead lines, and underground cables for Saudi’s electrical grid. The collaboration between GE Grid Solutions and Larsen & Toubro builds upon their successful track record in delivering transmission and distribution  projects in Saudi Arabia.
