ABOUT THE COMPANY

SOLUTIONS USING RENEWABLE ENERGY

PHILIPPINE CORPORATION ESTABLISHED IN 2004 DEVELOPER OF BIOGAS/BIOMASS PROJECTS BUILD-OWN-OPERATE-TRANSFER MODEL CURRENT PORTFOLIO :

BIOGAS PLANTS – 9 BIOMASS PLANTS – 3

BIOGAS DEVELOPMENT - BACKGROUND

MOSTLY BASED ON SWINE FARMS/ALCOHOL DISTILLERIES/BREWERIES/STARCH PLANTS FIRST PLANT GENERATING ELECTRICITY – 1992 MORE DEVELOPMENT POST 2000 DUE TO CDM TOTAL INSTALLED BIOGAS PLANTS - 50 (+) COVERED LAGOON TECHNOLOGY

ADAPTATION FROM OPEN LAGOONS CHEAPER TO BUILD AND OPERATE

BIOGAS DEVELOPMENT - BACKGROUND

TYPES OF SUBSTRATES AVAILABLE

- PIG MANURE - CHICKEN MANURE - CORN SILAGE - CORN COBS - RIZOMES - BANANA/PINEAPPLE PLANTATION WASTES - FOOD/MARKET WASTES - DISTILLERY WASTES

BIOGAS DEVELOPMENT – SUBSTRATES

BIOGAS DEVELOPMENT - TECHNOLOGY

UASB FOR WASTEWATER TREATMENT FROM INDUSTRIAL PLANTS (BIOGAS UTILIZATION FOR PROCESS STEAM) COVERED LAGOON TECHNOLOGY – PIG FARMS

ADAPTATION FROM OPEN LAGOONS CHEAPER TO BUILD AND OPERATE POWER GENERATION (100KW TO 1MW)

BIOGAS DEVELOPMENT – ENGINEERING FACTORS

CLIMATE – WET AND VERY WET AMBIENT TEMPERATURES – 25 TO 30 DEG C. EARTHQUAKES – TO BE EXPECTED LACK OF PRE-FABRICATED CONCRETE LACK OF CONSTRUCTION CRANES HIGH INTER ISLAND MOBILIZATION COSTS ELECTRICITY – INTERMITTENT (60HZ)

EXAMPLE 1 – COVERED LAGOON

EXCEL & AMIGO PIG FARMS – BULACAN WASTE-TO-ENERGY POWER ( 200KW On Each Farm) By Product – Fertilizer Carbon Credits – TERTIARY REVENUE Environmentally Compliant

BIOGAS DEVELOPMENT – COVERED LAGOONS

CASE STUDY– COVERED LAGOONS

CASE STUDY – CONCRETE TANKS

BUSINESS MODEL

BUILD-OPERATE-TRANSFER 5 TO 10 YEAR OPERATING PERIOD OFFER 10% TO 30% SAVINGS ON ENERGY PROVIDE O & M SERVICES AFTER TRANSFER

FINANCIAL CONSIDERATIONS

AVERAGE COST PER MW INSTALLED = 2 To 2.5 M EUROS DEBT FINANCING COSTS ARE HIGH (9% p.a.) SELL ELECTRICITY TO FARM – 10 CENTS EURO /KwH POTENTAIL FOR LARGE SCALE BIOGAS PLANTS

SOLUTIONS USING RENEWABLE ENERGY

POLICY CONSIDERATIONS

- REGULATED BY DEPARTMENT OF ENERGY - INCOME TAX HOLIDAY - FEED IN TARIFF – STILL EVOLVING - GRID INTERCONNECTION – POSSIBLE - GAS COMPRESSION – STILL EVOLVING

TECHNOLOGY CONSIDERATIONS

-OPPORTUNITY FOR BIOGAS COMPANIES - TURNKEY SERVICES - PROCESS/ ENGINEERING DESIGNS - SUPPLY OF COMPONENTS

- SUBSTRATES PREPRATION/LOGISTICS/STORAGE - TANKS/STIRRERS - GAS HOLDERS - GAS TREATMENT - POWER GENERATION - INSTRUMENTATION

SOCIO-ECONOMIC SIDE

-OPPORTUNITY FOR AGRICULTURE - REVENUE FROM WASTES - ORGANIC NUTRIENTS FOR SOIL

REHABILITATION - UNPRODUCTIVE LANDS UTILIZATION

- MINING AREAS FOR REHAB - VOLCANIC AREAS FOR REHAB - MARGINAL LANDS
