  1. Eskom’s response to Minimum Emission Standards Presented at the Parliamentary Portfolio Committee on Environmental Affairs' Air Quality Management Colloquium Date: 13 September 2017

  2. A few thoughts upfront… The Minimum Emission Standards are much needed to reduce harmful health effects of poor air quality in South Africa The MES provide certainty as to what level of emission reduction is required Eskom supports the MES and is doing its utmost to comply

  3. What has Eskom already done to comply with the MES? Particulate matter emissions Clean stacks after Grootvlei retrofit Matla ESP upgrade

  4. What has Eskom already done to comply with the MES? SO2 and NOx Fabric filter plant FGD absorber Island Boiler island Re-agent prep and gypsum de-watering 4

  5. What has Eskom done to comply with the MES? Budget commitment ~3% higher electricity tariff Cost (nominal) Description R63 billion Current emission reduction plan to 2025 (57% compliance) FGD at Medupi Low NOx burners at 3 stations FFP at 2.5 stations ESP upgrades at 4.5 stations Requested by DEA in the postponement decision in addition to Eskom commitment >R79 billion FGD at Matimba and Kendal ~10% higher electricity tariff Full compliance including retrofitting of stations close to end of technical life (risk cost) >R300 billion (total) FGD at 11 power stations Low NOx burners 11 stations FFP at 3.5 stations ESP upgrades at 4.5 stations

  6. Opportunities and challenges of MES compliance 6

  7. Eskom’s air quality offsets programme 2011-2013 2014-2016 2017 2018-2020 2019-2025 Insulation and electricity Tested insulation, LPG, clean coal stoves, electricity subsidy; electricity starter pack The implementation of an air quality offsets programme to reduce ambient particulate matter concentrations is a condition of the approved MES postponements granted to 12 power stations

  8. Air quality offsets: opportunities and challenges Insulated ceiling (and walls) Electric heater 4-plate stove and oven

  9. Concluding recommendations • Dialogue between government departments is needed to unlock conflicting mandates hampering full compliance with the MES (for example keeping electricity tariff low vs cost of reducing health burden; water for FGD) • A cost-benefit analysis is needed to prioritise retrofits and most efficiently channel scarce resources. • Could be done in partnership between DEA and industries • Eskom is commissioning independent cost-benefit analysis for power station emission reduction • Will give effect to section 5.4.3.3 of the National Framework for Air Quality Management in the Republic of South Africa: ‘The listing of activities therefore must be informed by appropriate analysis, such as cost benefit analysis’ • Eskom remains committed to reducing its environmental footprint
