"1,000MW Combined Cycle Power Plant & Strategic Micro-Grid Project - Zone A"

High-efficiency power plant using clean gas as fuel, with a seawater cooling system and utilization of Cold Energy from LNG

Project Information

  • Project Name : 1,000MW Combined Cycle Power Plant & Strategic Micro-Grid Project - Zone A
  • Client :
    1. Internal Anchored Customers
    2. Infrastructure Operators
    3. External Customers through Main Grid Connection (Grid Power Purchase)
  • Background & Rationale :
    To ensure stability and maximum system reliability (Zero Down-time) for all infrastructure within the Ranong Center project and ENOC's refinery, the project design specifies "Zone A Island" as an independent island grid (Stand-alone Island Grid) for the combined cycle power plant (Combined Cycle) with a capacity of 1,000MW. This is achieved by isolating the site on the island to maximize safety in managing high-pressure energy systems, along with installing emergency energy storage systems to ensure continuous operation of the power plant even during emergencies when external grid connections are unavailable.

Objectives :
1. To create a stable electrical and thermal energy system (Steam) to supply all infrastructure and energy storage facilities in Ranong throughout 24 hours
2. To develop Zone A Island into a self-sufficient strategic energy center that can operate independently during emergency situations
3. To enhance the potential for utilizing clean energy in the future through a hybrid system of natural gas and liquid hydrogen

Key Targets :
1. Install a total generating capacity of 1,000 megawatts (MW) : The system is designed with two production blocks (500 MW each) for maximum flexibility and efficient energy cost management.
2. Strategic Fuel Storage System on the Island :
  • LNG Storage Tank : 1 tank
  • LH2 Storage Tank : 1 tank
  • Security Criteria : The reserve volume of both tanks is calculated to be able to continuously supply fuel to the power plant (CCPP) for 5 full days without relying on external supply.
3. Substation and Closed-Cycle Cooling System : Installation of a gas-insulated substation (GIS) to save space and a heat recovery steam generator (HRSG) to provide steam for project activities.

Key Requirements :
1. Island Safety Standards (NFPA / API) : The placement of power plant buildings and LH2/LNG pressure vessels on the island must comply with the highest safety clearance standards and be equipped with automatic fire suppression and containment systems.
2. Unlocking Island and Marine Area Concession Rights : Approval for the use of Zone A island area must be obtained from the Cabinet and relevant agencies, along with an Independent Power Producer (IPP) License and the completion of a Marine and Coastal Environmental Impact Assessment (EHIA) report.

Location/Area :
  • Location : Zone A (Andaman Bay, Ranong) *(1 Rai = 1,600 Square Meters)*
  • Area : Zone A Island, strategically located with a total area of 70 Rai, designed to accommodate the power plant buildings (2 blocks), cooling system buildings, substation (Substation), and strategic fuel storage tanks for LH2 and LNG.

Budget :
  • Total Budget (Turnkey - EPC) : 54,000 – 60,000 Million Baht(THB) (Reference in Thai Baht)

Timeline :
  • Preparation and EHIA Phase : 6 - 9 months (starting immediately after receiving operational support)
  • Construction and Vessel Procurement Phase : 36 - 42 months (phased implementation)

Responsible Parties :
  • Contract Manager and Concession Holder : Golden Bridge Investment Holding (Thailand) Co., Ltd. (GBI Holding) as the concession holder of the island and energy pipeline

Expected Outcomes :
1. The entire Ranong project will have a highly stable and safe power grid system, separated from the power plant area and located on the sovereign island
2. There will be energy security guarantees, allowing the system to operate continuously for 5 days even in emergency situations, providing the highest level of confidence to global expert investors and customers who will lease the storage facilities
3. GBI Holding will control the "heart of the power switch" of the large Ranong project, generating enormous returns throughout the 50-year contract period
