Phase 3 will consist of the installation of a Vapour Absorption Chiller or “VAC” from Thermax in India for the purpose
of replacing the electricity used at present in the cooling of the storage facility at Letaba Estates, where the
perishable fruit juice is kept prior to shipment to clients. The VAC will be run off the waste heat produced by the
combustion of biomass in the plant (peel-driers and/or boilers).
The projected emissions reductions emanating from Phase 3 are estimated at 5 125 tonnes per annum. This is
calculated by multiplying the total number of hours per year with the projected load shifted (0.5 MW), with the
projected load factor of 0.9 and with the grid emissions factor of 1,31kg/kwH = 5 125 tonnes per annum. The
calculation of the grid emissions factor is attached hereto as Annexure 8.
The grid emissions factor is determined in accordance with AMS 1-D. version 13, paragraph 9(b) being: “The
weighted average emissions (in kg CO2e/kWh) of the current generation mix”. The data of the year in which project
generation occurs must be used.
It is anticipated that the grid emissions factor will increase in the next few years, as:
• Eskom, the national utility, is presently bringing three previously moth-balled, coal-fired power stations back
online. The three stations (Arnot, Komati and Camden) have installed capacity of
2 100, 1 000 and 1 600 MW respectively (aggregate 4 700MW) and will further increase the proportion of
grid electricity derived from fossil fuels;
• The renewable energy projects due to come on-stream in the next few years (Darling Wind Farm,
Bethlehem hydro and possibly some others) are unlikely to even approach 100 MW of installed capacity in a
national grid of approximately 42 000 MW installed capacity (0,23%);
• Eskom plans to ease pressure on capacity during peak hours by installing 1 000 MW of kerosene fired open
cycle turbines as soon as possible.

B.3. Description of how the anthropogenic emissions of GHG by sources are reduced below those that
would have occurred in the absence of the registered VER project activity:
As appears from the other parts of this document, the emissions reductions are clearly measurable. The emissions
from biomass in the Project Activity are zero. Using the emissions factors derived in section B.2. above, the coal use
