"A mega-power plant, 1,500 megawatts, is an offshore and coastal hybrid power plant offering ultimate energy security by combining Andaman solar power and monsoon winds, eliminating electricity costs to zero. It's further enhanced with a 1,000-megawatt CCPP backup system, ensuring 24/7 operation of industrial plants and chipping estates."

A 10 Sq.km. area is designated for a floating solar farm with a capacity of 800 MW, plus 47 offshore wind turbines of 700 MW, strategically placed along a 15-kilometer underwater energy pipeline.

Project Information

  • Project Name : Special Project: Integrated Hybrid Renewable Energy Complex (Hybrid Renewable Energy Complex: Floating Solar 800 MW & Offshore Wind 700 MW) under the Strategic Plan of Ranong Green Energy Hub
  • Target Customers :
    1. Customer on the "Excess Clean Electricity 300 MW" side (Chip Industry & Logistics)
    2. Customer on the "Green Ammonia 1.2 Million Tons/Year" side (Export Market for Energy)
    3. Customer on the "Clean Hydrogen and Marine Fuel" side (Maritime Logistics)
  • rationale :
    In the era of transition to clean energy (Energy Transition), heavy green industries such as green ammonia (Green Ammonia) and clean hydrogen require enormous amounts of electricity and must be stable 24 hours a day. Relying solely on one renewable energy source is not sufficient to meet these demands due to the limitations of natural variability. GBI Holding has designed the energy infrastructure in a "hybrid marine and coastal" form that integrates floating solar energy and offshore wind energy in deep sea, combined with an intelligent control system (EMS) and a combined cycle power plant (CCPP) of 1,000 MW to reduce reliance on external power grids (Zero Grid Reliance), reduce operational costs (OPEX), and create the highest level of stability in driving the factories of the future.

Objectives :
1. To develop a total of 1,500 megawatts of clean and renewable energy sources to directly supply the project's green ammonia and clean hydrogen production plants.
2. To create a fully self-sustained energy ecosystem through collaboration with the project's 1,000 MW CCPP power plant.
3. To reduce greenhouse gas emissions in the industrial production process to net zero (Net Zero Emission) and elevate Ranong Province to become a center for clean energy in the ASEAN region.

Key Targets :
1. Establish and install a floating solar power plant with a capacity of 800 megawatts (MW).
2. Establish and install an offshore/coastal wind turbine power station with a capacity of 700 megawatts (MW).
3. Implement dynamic load shifting: delivering a maximum of 2,200 MW during the day and managing the power to 1,400-1,500 MW continuously at night, 24 hours a day.
4. Have a surplus of 300 megawatts (MW) of clean electricity available for commercial distribution to neighboring innovation zones and industrial estates (e.g., advanced semiconductor industries).

Key Requirements :
1. Floating Solar (800 MW) : Requires high-density polyethylene (HDPE) industrial-grade buoys resistant to saltwater corrosion and sea spray, along with double-glass bifacial solar panels for maximum light reflection from the water surface.
2. Wind Turbine (700 MW) : Utilizes large-scale marine-grade wind turbines to withstand the monsoon winds of the Andaman Sea, and employs an anchoring system designed to minimize underwater environmental impact.
3. Energy Management System (EMS) : Installs an AI and Smart Grid system for seamless switching between renewable and inert energy sources. and the CCPP Combined Cycle Power Plant No. 1 (1,000 MW)
3. Environmental Compliance : Construction and site planning must pass an Environmental Impact Assessment (EIA) and not affect commercial shipping routes, including natural coral reefs.

Location/Area :
  • Location : Located along the underwater energy pipeline, 15 kilometers in length
  • Area : Coastal sea area and water surface area strategically positioned around the Ranong Clean Energy Conversion Center, Ranong Province, Thailand (directly connected to the internal power grid of GBI Holding)

Budget :
  • Total Budget (Turnkey - EPC) : 180,500 Million Baht(THB) (Reference in Thai Baht) **(Financial structure ratio: Equity 30% : Debt 70% with tax benefits from BOI for 8 years)**

Timeline :
  • Construction and Installation Period (Phase 1 - Construction) : Year 1 – Year 4 (Total 48 months)
  • Commercial Operation Start (COD & Operation) : From Year 5 onwards (Projected payback period of the project is 7.2 years, with a payback period of just 3.2 years after the COD begins)

Responsible Parties :
  • Main Project Developer : Golden Bridge International Holding (Thailand) Co., Ltd. (GBI Holding) in partnership with a group of world-class marine energy engineering specialists (Tier-1 EPC Contractors)

Expected Outcomes :
1. The project has a power grid infrastructure to support the full production capacity of the green ammonia factory at 1.2 million tons per year, with the lowest average electricity cost in the region
2. The project can save on costs from purchasing electricity from external sources (Grid Power) by 100%, amounting to cost savings (OPEX Saved) of over 60 - 80 million USD per year
3. It can generate additional revenue from selling stable premium electricity (Baseload Green Power) of 300 MW into GBI Holding's revenue pool, adding over 120 million USD per year
4. It attracts investment and joint funding from international large-scale energy funds (e.g., funds in the Middle East) with a stable financial model, quick return on investment, and sustainable long-term profitability exceeding 30 years
