UACJ (Thailand)
Target Load: ~280–320 GWh/year
Solar Rooftop Installed: 25 GWh/year (~6% of load)
Electricity Output: ~223 GWh/year (85% CF)
Fuel Requirement: ~600 tons/day (woodchips, bagasse, rice straw mix)
Technology: High-pressure steam boiler (92–100 bar, 500–540 °C), condensing turbine-generator
Environmental Controls: Multicyclone + baghouse (10–20 mg/Nm³), SNCR for NOx
Land Requirement: ~50–65 rai (8–10 ha), including fuel yard, boiler island, cooling, water ponds, and ash handling
Electricity Output: ~37 GWh/year (85% CF)
Thermal Output (CHP): ~40–45 GWhₜ/year (hot water/low-pressure steam for annealing and cleaning processes)
Feedstock: ~16 million Nm³ biogas/year (Napier grass, manure, food waste mix)
Digesters: ~36,000 m³ total volume (3–4 CSTR tanks, mesophilic 37 °C)
Gen-sets: 3 × 1.7 MWe or 5 × 1 MWe
Land Requirement: ~11–18 rai (1.8–2.9 ha), including digesters, gas handling, CHP units, and digestate treatment
On-Site RE Power: ~260 GWh/year
DPPA/Offsite RE: 30–60 GWh/year (10–20% of load)
RE Penetration: 75–90% of factory electricity demand in Year 1
Biomass Power Plant: 50–65 rai (8–10 ha)
Biogas CHP: 11–18 rai (1.8–2.9 ha)
Total: ~60–80 rai (10–13 ha) for Phase 1
Add ~5–10 MWe (biomass or biogas) to reach ~35–40 MWe on-site
Reduce DPPA share to ~10%
Secure full RE100 compliance (~100% renewable electricity supply)
Land Requirement for the Expansion Phase: +6–20 rai (depending on fuel storage strategy)
Water Consumption: ~0.35–0.5 million m³/year (cooling towers, process, biogas slurry)
Ash Production: ~5,000–7,000 tons/year (potential for soil amendment or cement additive)
Digestate: Solid fraction for compost/fertilizer; liquid fraction treated and partially reused
Biomass 30 MWe: US$60–75 million
Biogas 5 MWe: US$12–18 million
Infrastructure & Balance: US$12–18 million
Total Phase 1 CAPEX: ~US$85–110 million
Construction Timeline: 20–24 months to COD (EIA, permits, EPC, commissioning)
Phased Risk Management – Start with 35 MWe (Biomass + Biogas) plus DPPA, expand based on proven load and feedstock security.
RE100 Certification Ready – On-site renewables + certified DPPA ensure compliance with global supply chain standards (CBAM, RE100, ESG).
Circular Economy Model – Agricultural residues and organic waste valorized into renewable energy and by-products (ash, digestate).
Scalability & Reliability – Dual biomass blocks + modular biogas CHP for redundancy, load flexibility, and long-term growth.
Strategic Location – Situated in the EEC, with secure logistics, port access, and proximity to major downstream customers.
