EVNNPT reviewed construction of the 220 kV Sam Son substation and its connecting line, aiming for energisation in December 2026. The Government News portal reports two 250 MVA transformers and approximately 40.1 kilometres of transmission line. The station site and all 111 tower-foundation locations have been handed over, although some corridor issues remain. The investor called for coordination with local authorities, faster construction and completion of acceptance requirements before operation.
