These partnerships delivered the first multi-vessel plug-in facility at Phuket Deep Sea Port in 2023, which now supplies 5 megawatts of stable power to visiting luxury cruise liners. This technical synergy allows for rapid scalability across the Andaman Sea coastline, ensuring that electrical grid stability is maintained even during peak tourism seasons.
Market Challenges
Inconsistent Grid Infrastructure
Many secondary provincial ports in Thailand lack the high-voltage distribution networks required to support heavy vessel loads. Only 22 percent of medium-sized coastal terminals in the Surat Thani region possess the electrical capacity to facilitate stable cold ironing without inducing local power flickers.
Prohibitive Capital Expenditure
The initial cost of installing specialized transformers and automated connection systems remains a substantial barrier for private port operators. Deploying a single ship-to-shore connection system currently costs an average of 120 million Thai Baht, leading many domestic terminal managers to defer infrastructure upgrades indefinitely.
Fragmented Technical Standardization
The lack of a unified national regulatory standard for shore power connections forces operators to manage diverse equipment specifications from international suppliers. Currently, 35 percent of docked vessels in Thai waters remain incompatible with existing land-side power sockets due to conflicting frequency and voltage requirements.
Opportunities
Laem Chabang Port Electrification
The expansion of Terminal F at Laem Chabang creates immediate demand for high-voltage cold ironing infrastructure to reduce reliance on auxiliary diesel engines. Port authorities have mandated that all newly constructed berths integrate standardized shore-to-ship connection points by 2026.
