Tambon Scale

1. Warehouse Size & Specification

Functional Role

• Central aggregation hub for 10–20 village-scale warehouses

• Buffer storage feeding compost plants and biomass power plants

• Quality control, moisture management, and inventory tracking

• Contract-secured feedstock for SPV-owned assets

Physical Specifications

• Covered floor area: 2,000–3,000 m²

• Clear height: 8–10 meters

• Storage capacity: 2,000–3,500 tons/year (loose biomass equivalent)

• Land requirement: 4–6 rai (≈ 6,400–9,600 m²)

Structural Design

• Structure type: Fully roofed steel warehouse

• Columns: Hot-dip galvanized steel columns

  • Column spacing: 8–10 m

• Roof system:

  • Corrugated metal sheet or insulated metal panel

  • Ridge ventilation for heat dissipation

• Flooring:

  • Reinforced concrete slab (150–200 mm)

  • Designed for loader and truck traffic

• Drainage: Peripheral drainage channels

• Fire safety: Zoning, fire breaks, temperature monitoring points

• Ventilation: Natural + passive airflow (no complex systems)

Indicative CAPEX

• THB 6 – 10 million per warehouse

2. Equipment Specification

Tambon-scale warehouses are light-industrial logistics assets, optimized for reliability and low O&M complexity.

Core Equipment (On-Site)

• Wheel loader (or skid steer)

• Forklift (3–5 tons)

• Fixed or mobile weighbridge (40–60 tons)

• Moisture monitoring equipment

• Fire safety equipment (extinguishers, zoning sensors)

Interface Equipment

• Baler interface (biomass delivered from villages)

• Truck loading bays (10–12 wheel trucks)

• Inventory management & basic digital tracking (optional)

Operational Model

• Operated by SPV or contracted operator

• Village-level equipment financed separately via concessional loans (GSB / BAAC)

• No proprietary or high-risk technology exposure

3. Return on Investment (ROI)

Tambon-scale biomass warehouses generate stable, utility-like cash flows and materially enhance the economics of compost plants and power plants.

Revenue Streams

1. Biomass handling & aggregation fees

   • THB 200–350 / ton

2. Storage & inventory management fees

   • THB 100–200 / ton

3. Biomass resale margin

   • THB 150–250 / ton

4. Optional service contracts

   • Clean-air / residue-management programs

Annual Throughput Assumption

• 2,500–3,000 tons/year

Indicative Annual Revenue

• THB 1.0 – 1.8 million

Operating Cost

• Labor, equipment, maintenance, utilities

• THB 350,000 – 500,000 / year

Indicative EBITDA

• THB 600,000 – 1.3 million / year

Metric Range  (Per Warehouse)

CAPEX THB 6 – 10 million

EBITDA Margin 55–70%

Payback Period 5 – 7 years

Asset Lifespan 20–25 years

IRR (Standalone) 12 – 16%

IRR (Integrated Platform) 18 – 22%+

When bundled into a cluster SPV supporting compost plants and biomass power plants, Tambon-scale warehouses materially improve project bankability, debt terms, and time-to-COD, increasing overall platform IRR. 

The Tambon Warehouses provide:

• Low regulatory risk (non-power asset)

• High strategic leverage over energy projects

• Stable, infrastructure-like returns

• Strong ESG impact (PM₂.₅ reduction, rural income)

• Scalable replication across provinces

• Eligibility for blended finance and concessional support

They are best viewed as mission-critical infrastructure, not standalone real estate.
