PROJECT DESIGN DOCUMENT FORM (GS-VER-PDD) Voluntary Offset Projects - Version 01 The busiest period at Letaba Estates coincides roughly with the citrus fruit season. During late February/early March preparations begin for the production of citrus fruit juice and the juicing plant runs at a high steam load factor until early in December. Maintenance can be done in the intervening 3 month period until the following autumn. The project will be done in three phases. The projected dates at which each intervention will take place are approximate and the intention where possible is to deliver these interventions sooner rather than later. Phase 1 This template shall not be altered. It shall be completed without modifying/adding headings or logo, format or font. page 4 Phase 1 will commence in October 2009. Work will start on replacing the peel presses in order to improve the peel press efficiency and on the conversion of the two peel driers to run on biomass in the form of sawdust/wood chips. It is projected that Phase 1 will be commissioned on 31 December 2009. The result will be a complete fuel switch in the peel driers and higher efficiency, leading to projected VERs of 4 647 per annum. As a conservative measure 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 seven years, being 3 991 tonnes, equating to 5 286 VERs per annum. Phase 2 In October 2008 some steam efficiency measures will be implemented and an order for a biomass boiler in the 15-16 tonne per hour range will be placed. When the steam demand is clear another, smaller boiler in the 5-8 tonne range will be installed primarily to cater for very unusual peaks in demand. The first boiler is projected to be commissioned on 1 July 2010 and the second on 1 January 2011. Phase 2 is thus the replacement of the present coal boilers. The first boiler will be from Thermax and the second, if affordable, will also be from Thermax. If a second Thermax boiler is not affordable, a used John Thompson boiler will be converted to also burn biomass. After 1 January 2011, barring an emergency, no coal will ever be burnt again at Letaba Estates. Phase 3 Phase 3 targets the electrical energy consumption at Letaba Estates. At present the plant uses a maximum of approximately 0.5 MW grid electricity, primarily to cool fruit juice in storage. There is an opportunity to use waste heat from the production process at Letaba Estates to drive a Vapour Absorption Chiller (“VAC”) in order to provide cooling that will remove the need for grid electricity-based cooling. It is difficult to predict when the VAC will be installed as it cannot easily be done while the initiatives mentioned above are in progress. For purposes of this document it has been assumed that work on the VAC will commence on 1 October 2010 and will be completed another 3 months later (31 December 2010). Biomass is renewable (EB 23 annex 18) The biomass that will be used as a feedstock (sawdust and wood chips) is a biomass residue and the use of that biomass residue in the Project Activity does not involve a decrease of carbon pools, in particular dead wood, litter or soil organic carbon, on the land areas where the biomass residues are originating from. Biomass residue is usually defined as “biomass by-products, residues and waste streams from agriculture, forestry, and related industries”. The collection of the sawdust will not affect the forestry practices in the area and will not impact upon the carbon stocks. The sawdust and wood chips come from Eucalyptus Grande and Pine, species of tree used commonly for forestry in the area. Project structure The project in all phases will be developed by BioTherm Energy but owned by Letaba Estates.
PROJECT DESIGN DOCUMENT FORM (GS-VER-PDD) Voluntary Offset Projects - Version 01 The VERs will accrue to BioTherm Energy for its development services but in terms of a contractual agreement Letaba Estates and a to-be erected Worker’s Trust will share in the proceeds. In each Phase the VER income will increase. The project is not viable without carbon finance and faces amongst other things investment barriers and barriers of prevailing practice. Contribution to sustainable development On an economic level the project makes a contribution towards national economic development in that some employment will be supported both in the construction and commissioning phases (an estimated 10-15 contracting and 1-3 permanent jobs) by the end of Phase 3. The project will also lead to local skills development in the installation and maintenance of the peel driers and biomass/converted boilers. This template shall not be altered. It shall be completed without modifying/adding headings or logo, format or font. page 5 On a social level the VER income share held by the Worker’s Trust will see the trust earning money going towards the aims decided upon by the Trustees - which are likely to include study bursaries for workers and their children and the improvement of the housing of workers who live on the farm. This will contribute towards the eradication of historical economic imbalances in the country. In both Phase 1 and Phase 2 the project will utilize biomass wood chips or sawdust for energy. The biomass will be used to displace coal, an environmental hazard that not only creates greenhouse gas emissions but also soot and dust. If sawdust can be burnt a significant local environmental hazard in the form of sawdust waste heaps will be ameliorated. It is hoped to in this way create a win-win solution. At present the ash from the boilers at Letaba is landfilled on the property. In the Project Activity less waste will be produced (because the coal has a 14% ash content and the biomass only 3%) and it will be landfilled as before. If all peels are dried and none are landfilled, methane formation will be further avoided on the Letaba landfill (no VERs will be claimed for this). A projected 100 000 VERs emanating from the project will via the myclimate foundation be traded to FIFA to offset the emissions from the 2006 World Cup in Germany. As required the sustainable development assessment of the project has been completed. The matrix can be found in Annex 4. Total score of the project is +8, all categories score positive, and no negative indicators were recorded. It can therefore be concluded that the project positively contributes to a sustainable development. A.3.
