          "Formally awarded on September 30, 2026, the multibillion-riyal contracts mandate the engineering, procurement, and construction of four heavy-duty Bulk Supply Point (BSP) substations. The facilities will interface multi-gigawatt solar and wind generation with NEOM Green Hydrogen Company’s (NGHC) electrolyzer plants.",
          "Each substation features double-busbar 400 kV and 132 kV gas-insulated switchgear engineered for severe desert coastal environments characterized by saline humidity, ambient temperatures reaching 52°C, and abrasive sand ingress."
