2  Large industrial players ◦ smelters, pulp and paper mills, refineries, steel producers, chemical plants, large mining houses, etc.  Smaller industrial players: ◦ Niche plastic and chemical producers, hospitals, prisons, manufacturing processes, agro- processing, confectionary producers, independent miners, etc.

3  High energy efficiency  No/little need for new transmission infrastructure  Quick implementation for many projects  High capacity factors  Typically electricity is produced where it is consumed  Competitive space developed by private sector

4 Net Importers of electricity (Embedded Generators) Net Exporters of electricity (“IPPs” that sell power) Typically see electricity as a utility and non-core (threat) Likely see electricity as a core product Use all of the “cogeneration” electricity “within the fence” May use some of the “cogeneration” electricity; but exports “beyond the fence” Net Exporter Net Importer

5 Net Importers of electricity (Embedded Generators) Net Exporters of electricity (“IPPs” that sell power) Reduces grid “demand”- classic demand side management (DSM) Does reduce grid “demand”, but is typically aiming to supply electricity Typically 1-3 year planning horizons Typically 7-20 year planning horizons Net Importer Net Exporter

6  The Industrial Sector needs support to develop cogeneration projects; two important typical incentives; ◦ Power Purchase Agreements (PPAs) through Procurement Programme ◦ Capital Incentives for Cogeneration/ Energy Efficiency Projects  These two enablers each enhance the viability of cogeneration projects

7 Capital IncentivesPower Purchase Agreements (PPAs) Short term Capital injection to overcome initial private CAPEX outlay over 3 years Long term PPA to assure income over the 5-20 years Successful Example: ESKOM’s Integrated Demand Management (IDM) initiatives Successful Example: Renewable Energy Independent Power Producer Procurement (REIPP) Programme Typical Term: Up to 3 year term over which “incentives” are realised against Cogeneration performance Typical Term: 5-20 years realised against Cogeneration performance Contractual Burden: Low Contractual Burden: High

8 Net Importers of electricity (Embedded Generators) Net Exporters of electricity (“IPPs” that sell power) Use all of the “cogeneration” electricity “within the fence” May use some of the “cogeneration” electricity; but exports “beyond the fence” Reduces grid “demand”- classic demand side management (DSM) Does reduce grid “demand”, but is typically aiming to supply electricity as well Key Incentive: Capital Incentive i.e. ESKOM’s Integrated Demand Management (IDM) initiatives Typical Incentive: Sector typical Power Purchase Agreement (PPA) Note Capital Incentive may be applicable too.

9  The entity typically sees electricity as non-core, and a business threat  A capital incentive programme will accelerate efficient cogeneration from private sector  No power purchase agreement (PPA) involved, as power is used on-site  No impact on the grid  These projects represent Demand Side Management (DSM) or Integrated Demand Management (IDM) projects, and alleviate the already overburdened grid

10  ESKOM have an existing Integrated Demand Management (IDM) Programme  Has enabled a few Cogenerator Projects  Reported that these ESKOM IDM initiatives have been suspended by ESKOM and/or NERSA due to funding constraints.  Severe blow to the embedded cogenerator potential  Accelerate the Reinstatement of the Capital Incentive Scheme to realise Cogeneration in this sector

11 An ESKOM IDM Sponsored Project

12  Up to 6.4MWe will be generated equating to approximately 47 803MWh per year or 3 983MWh per month of cogeneration  Indication of the electricity produced due to “cogeneration” over a typical 24 hour are shown below. 24 Hours Kilowatts electrical

13  This project has contributed and contributed favourably to the Sustainable Development of its region  Increased job opportunities in an Industrial center  Transfer of specialist technology and economic growth into the Industrial center.  Combating of climate change by reductions in carbon emissions and water consumption.  Alleviated Transmission and Distribution Constraints
