Rice husk power

A biomass power plant which consists of a biomass boiler, a generator

plantset (genset) and auxiliary equipment. The biomass boiler generates
heat by combusting rice husks as its fuel, and the genset uses the heatto generate electricity.

Power generation

Electric output that a genset can generate, which is the installed/rated

capacity

capacity indicated by the manufacturer.

Power generation

Ratio of rated electric output to fuel input, which is the theoretical

efficiency

efficiency indicated by the manufacturer. It may also be the product ofheat generation efficiency of a biomass boiler (net heat output / fuelinput) and power generation efficiency of a genset (rated electric
output / heat input), each of which is the theoretical efficiency
indicated by the manufacturer.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated based on the net amount of electricity generated by a ricehusk power plant which replaces grid electricity and/or captive use where the project is
implemented during a given time period.
In general, auxiliary equipment of a rice husk power plant, when in operation, consumes
electricity generated by the power plant itself, but all the auxiliary equipment is not always inoperation, nor do they operate at maximum load. To ensure conservativeness in thismethodology, it is assumed that all the auxiliary equipment operates all the time at theoreticallymaximum load during a given monitoring period. Hence, the net amount of electricity
generated by the rice husk power plant can be calculated lower than the actual case, whichleads to net emission reductions.

F.2. Calculation of reference emissions

In case where the rice husk power plant is connected to both the national grid and a recipientfacility, and the amount of electricity generated by the rice husk power plant and supplied to
the national grid is identified, the following equation may be used for calculating the reference
emissions by applying the value of ‫ܨܧ‬ோா,௘௟௘௖ separately to each amount of electricity asinstructed in the section I of this methodology.
