^{_{GUIDELINE (CHECKLIST)}}

The Feed-in Tariff (FiT) is a policy mechanism in Malaysia which allows electricity produced from renewable resources to be sold to power utilities at a fixed premium price for a specific duration to enable financial viability of renewable energy (RE) plant development. The FiT mechanism was introduced through Renewable Energy Act 2011 [Act 725] in order to promote RE generation in Malaysia. One of the renewable energy (RE) resources which qualify under FiT is biogas which abundantly available from waste resources such as landfill, sewage gas or agriculture waste including animal waste as fuel source.

It is the legal responsibility of SEDA Malaysia, the Authority to ensure that all biogas installations approved are designed and constructed in accordance to the international standards and best practices, while meeting minimum national safety standards for the protection of personnel and equipment. The Guideline on Biogas Power Plant Acceptance Test and Performance Assessment (AT&PA) for FiT Projects in Malaysia is prepared to provide assistance to the Feed-in Approval Holder (FiAH) under the biogas installation. This Guideline is useful when preparing the plant performance assessment reporting by the biogas project developers in preparing test report for FiT Commencement Date (FiTCD).

This Guideline/Checklist is in addition to, and intended to complement, not replace, the Electricity Supply Act, the Renewable Energy Act, the Occupational Safety and Health Act, and their related subsidiary legislation. It serves to provide simple yet clearer guide as to the step-by-step in conducting the AT&PA as required by the Authority.

This Guideline/Checklist consists of five (5) parts;

a) Checklist of AT&PA documentation;

b) Information about the Project;

c) Information about the Plant;

d) Acceptance Test & Reliability Run; and

e) Fuel sampling & Electrical Efficiency.

The AT&PA must be carried out by the respective FiAH’s Competent Persons in the presence of SEDA Malaysia’s representatives. A minimum notice of 14 days is required for the AT&PA arrangement, together with the payment of the prescribed fee. The AT&PA fees to be prepared in Bank draft or Bankers cheque in favour of “Sustainable Energy Development Authority Malaysia”.

Region	AT&PA Fee (including GST)
Peninsular Malaysia	RM41,509.00
Sabah & Labuan	RM45,283.00

In the event the AT&PA works need to be postponed or repeated due to unreadiness or fault by feed-in approval holder, additional charges of RM1,000.00 per day will be imposed to FiAH for the number of days to complete the AT&PA works.

^{_INTRODUCTION}

The most common approach to produce electricity from biogas is through gas engine either spark ignition (SI) or compression ignition (CI). It is because gaseous fuelled reciprocating is matured technology in terms of global manufactures supply and support efficient infrastructure. Moreover, this technology is more tolerant to biogas impurities and need less initial cost than other technology. Meanwhile, biogas is a renewable and sustainable energy carrier produced via Anaerobic Digestion (AD) in humid condition with absence of Oxygen or biological decomposing or organic matter in landfills. Biogas mainly consists of Methane (40-65%), Carbon Dioxide (30-45%) and some other compounds. The compositions of biogas vary from one source to another and also depend on condition of the digester or the landfill.

In reciprocating engine, the combustion occurs in enclosed combustion chamber where the thermal energy that generated due to combustion expand and converted into mechanical energy by rotating the crankshaft which is coupled with generator to produce electricity. Figure 1, shows the typical biogas fired gas engine power plant.

FUEL SAMPLING & ELECTRICAL EFFICIENCY

Should the Engine data sheet and FAT certificate show a value of less than 40% electrical efficiency, the fuel sampling and electrical efficiency test will not be conducted.

5.1 Fuel Sampling;

The fuel sampling shall be carried out by an Accredited Laboratory of Skim Akreditasi Makmal Malaysia(SAMM).
It is recommended that the fuel sampling be taken at 100% Rated Engine Load (REL).  Minimum parameters of biogas to be analysed;
Methane composition, CH₄(%)

Carbon Dioxide, CO₂(%)
Oxygen, O₂(%)
Hydrogen Sulphide, H₂S (%)
Ammoniacal Nitrogen, NH₄(%) - (if biogas landfill)
Net Heating value of biogas (kJ/kg)
Moisture content (ppm)
Real Density of biogas (kg/m³)

FiAH is required to complete Form 5a for fuel sampling documentation.

5.2 Electrical Efficiency;

The Electrical Efficiency (EE) requirement is to measure gas engine performance by using actual biogas at site. FiAH is required to complete Form 5bfor electrical efficiency documentation.
FiAH needs to provide the EE detail calculation. The plant log data (in VSC format) and laboratory result are to be attached to support the calculation.
The maximum EE value for each test will be based on the Factory Acceptance Test (FAT) certificate for each engine.
FiAH is eligible for the FiT bonus of use of gas engine technology with EE if the calculation of EE is above 40%.
