Letaba Biomass to Energy PDD - MyClimate

SECTION B. Application of a baseline methodology
PROJECT DESIGN DOCUMENT FORM (GS-VER-PDD)
Voluntary Offset Projects - Version 01
B.1. Title and reference of the approved baseline methodology applied to the project activity:
Phase 1
Gold Standard VER Small Scale Methodology, “Ecologically sound fuel switch to biomass with reduced energy
requirement” version 1 – (fuel switch in peel driers) 2 .
Phase 2
Gold Standard VER Small Scale Methodology “Ecologically sound fuel switch to biomass with reduced energy
requirement”, version 1 – (fuel switch in boilers)
Phase 3
AMS II.D “Energy efficiency and fuel switching measures for industrial facilities“, version 11 (vapour absorption
chiller)
B.1.1. Justification of the choice of the methodology and why it is applicable to the project
activity:
Phases 1 and 2 3
This methodology was developed especially for this project to cater for the situation where there is a fuel
switch from fossil fuel to biomass that also changes the efficiency.
This template shall not be altered. It shall be completed without modifying/adding headings or logo, format or font.

The situation at Letaba Estates is that production varies in different years according to the size of the
harvest and the type of fruit juice produced at the plant (sub-tropical fruit juice and single strength juice
require different amounts of energy to process). It is thus not possible to determine an a priori baseline
against which project emissions can be measured as it cannot be predicted what production levels or the
production mix will be in any given year. If in such a scenario the energy input is measured in the project
activity, the proponent will not get the benefit of energy efficiency improvements as it would tend to produce
an artificially low baseline.
The answer is to determine an a priori energy usage (and implicitly an a priori emissions factor) for both
citrus and single strength juice and monitor output for an accurate baseline that gives credit for efficiency
improvements.
2 As a conservative measure and in accordance with the methodology, given that the baseline is determined ex post
and efficiency will improve (effectively expanding the capacity of the peel drier) the VERs will be capped at the
equivalent of the highest amount of peels dried in the last five years, being 5 286.
3 As a conservative measure and in accordance with the methodology, given that the baseline is determined ex post
and efficiency will improve (effectively expanding the capacity of the peel drier) the CER’s will be capped at the
equivalent of the highest amount of peels dried in the last five years, being 3 991 tonnes per annum
