Small-Scale Alternative Energy Options & Projects for Rural (Remote) Areas

SCOPE OF PRESENTATION:


• Rural Electrification and Role of Solar (PV)

Systems;• The Household Electrification Project (HEP) and the Rural Electrification Project (RPP)• Small – Scale Gasifiers;• Biogas


The O-Ilaw and BEP (1999; 2001)

• Designed to address the goal of providing electric power to all barangays nationwide (41,995 in remote locations). As of Dec. 31, 2010, 99.89% have been energized.

• Goals: - Improve quality of life; - Better access to rural development; - Stimulate socio-economic growth in rural areas;

Barangay Electrification Partners in the Visayas

• Renewable Energy Management Bureau – DOE (EUMB-DOE)

• Phil. National Oil Company (PNOC)• Dept. of Interior & Local Gov’t. (DILG – MSIP)• Aus – Aid (MSIP)• ADB (8 barangays in Negros Occ.)• Japan International Cooperation Agency (JICA)• Kingdom of Belgium• GTZ • Power Bureau – DOE• Distribution Utilities• Independent Power Producers• NGO’s, e.g. World Vision & Philgerfund• Affiliated Renewable Energy Centers (AREC)


Issues & Problems

Communities need to be fully capacitated to maintain their systems;

Given the high initial cost of the system, gov’t. subsidy is still needed;

Some replacement components are not readily available or, as in the case of some batteries, not reliable;

The low power capacity of the installed systems precludes the use of household appliances, unless these are upgraded for the purpose;

Most systems installed depended largely on aid funding

These two are expansion programs to augment the BEP;

Target : Sitios situated far from the grid (between 2 – 5 km) and have not availed of the BEP;

Implemented in partnership with Distribution Utilities (DU);

Counterpart funding of P 1,000 from HH + P 150 – 250 monthly fee;


HEP (EUMB) and RPP (PB)


HEP (EUMB) and RPP (PB)

HEP System : one (1) 30 Wp Solar Panel good for three (3) 3 – watt LED lights;

RPP System : one (1) 50Wp Solar panel good for two (2) 3 – watt LED + provision for DC-TV (preferably LCD)

HEP initially targetted 14 sitios (370 HH) in 2010;

Other Potential Energy Sources

Gasifier

WOODGAS ICE PLANT



Gasifier

Reactor and Cornmill



Gasifier

BIOMASS MULTICAB with ELECTRIC GENERATOR



Gasifier

Benefits:

source of energy (methane); reduction of gas emissions which contribute to global

warming through methane capture (methane is 21 times more potent than CO2 as a pollutive gas)

protects ground water acquifers from leachates arising from livestock waste, e.g., poultry & hogs;

biodegraded waste & wastewater are utilized in farms as organic fertilizer and pest repellants



Biogas

As a source of energy, a cubic meter of biogas has the following equivalents: 0.454 Kg of LPG (1 LPG = 11.0 Kg) 0.52 Liter of Diesel Fuel 0.80 Liter of Gasoline 0.62 Liter of Kerosene 0.60 Liter of Crude Oil 1.10 Liter of Alcohol 1.50 Cubic Meter of Natural Gas 1.40 Kgs of Charcoal 4.70 Kw-Hr of Electricity 3.47 Kgs of Firewood 0.43 Kg of Butane12.30 Kgs of Cattle Dung Cake



Biogas

For small backyard livestock, biogas provides energy for domestic needs
