Cogen 3 Programme

• is the third phase of the European Commission
  (EC)-ASEAN cooperation programme
• promotes the implementation of Proven, Clean and
  Efficient Biomass, Coal and Gas cogeneration
  projects by facilitating business partnerships
  between EU suppliers and ASEAN industries
• The Full-Scale Demonstration Project (FSDP) a
  grant of 15 of the cost of the equipment will be
  given to a project that qualifies as FSDP. An
  FSDP is a showcase in ASEAN aiming to convince
  other potential end-users to select the
  appropriate technology in order to replicate
  successes.

Cogeneration

• Cogeneration (Combined Heat and Power or CHP) is
  the simultaneous production of electricity and
  heat, both of which are used.

Angkor Rice Mill
10
The rich, fertile soil of Central Cambodia
provides optimal environment for growing Neang
Malis rice
11
Angkor Rices carefully selected planting area is
in four provinces in Central Cambodia Kandal,
Kampong Speu, Takeo and Kampot
12

13
The regions (central Cambodia) naturally fertile
and sandy soil enables farmers to grow Angkor
Rices premium-quality Neang Malis rice in a
traditional way without chemicals.
14
More than 25,000 families are Angkor Rices
members and growing Neang Malis rice. There are
no middlemen. Angkor Rice sets a high standard.
The Agriculture Division distributes high quality
seeds and instructs the farmers in planting rice.

Proposed Rice Husk-Fired Cogeneration Power Plant
Angkor Rice Mill

• Steam turbine system with 1 MW electric capacity
• Present capacity of the mill is 10 tons/hour.
  Proposed expansion of another 10 tons/hour
• Rice husk will be used as fuel
• Two scenarios
• steam has no value
• steam has value equal to 50 of the cost for
  steam generation in a boiler using fuel oil
• Excess Electricity exported to other customers
• Utilization of heat for drying

18
Proposed Rice Husk-Fired Cogeneration Power Plant
Angkor Rice Mill

• Scenario Steam has no value
• Total Investment Cost including contingency 1.5
  million euro
• Net Present Value 3.1257 million euro
• IRR 49.7
• Discounted Payback Time 2.3 years
• Cogeneration Project Lifetime 20 years

19
Proposed Rice Husk-Fired Cogeneration Power Plant
Angkor Rice Mill

• Scenario Steam has value equal to 50 of fuel
  oil cost
• Total Investment Cost including contingency 1.5
  million euro
• Net Present Value 4.659 million euro
• IRR 64.4
• Discounted Payback Time 1.6 years
• Cogeneration Project Lifetime 20 years

20
Cogen3 Pre-evaluation and Recommendations

• Project seems feasible
• Further investigations are recommended,
  concerning
• detailed design (electricity capacity of steam
  turbine, utilization of capacity)
• necessary investment
• real value of steam (benefits of drying using
  steam)
• necessary investment in drying process
• necessary investment in electricity distribution
  grid
• all issues, (especially government regulations)
  related to selling of electricity to other
  parties
• Requires a full feasibility study and
  investigation

21
Benefits of the Rice-Husk Cogeneration Power Plant

• Environmental Benefits
• Less pollution
• Uses rice husk, which is considered an
  agricultural waste
• Economic Benefits
• Savings (electricity production)
• Income generating (selling excess electricity,
  ash sales)
• Generates job
• Saves on fuel, no foreign currency needed

22
Opportunities in Cambodia

• Biomass opportunities in rice mill, rubber
  processing plants, palm oil refinery
• Gas gas supply in Cambodia is in the
  exploratory stage. If gas is available, there
  will be opportunities in Buildings (hotels,
  restaurants, hospitals, schools, offices,
  supermarkets,etc.) and Industries (cement,
  pharmaceuticals, garments)
